The way you talked about the end of Voyager II operations reminded me of the time the doctors accidentally turned down my grandfather's pacemaker's levels just a little too much. My grandmother is rumored to have yelled "TURN HIM BACK ON!" loudly enough that he, with almost no functional heart rhythm, heard her loud & clear.
Correction Dr. Becky -------The ring nebula is a planetary nebula formed when a star like our sun expels material in its dying stages (the ring) and becomes a white dwarf (seen in the center of the ring). The star consists mostly of carbon and oxygen. An example of a supernova remnant is the crab nebula with its many tendrils, formed when a much more massive star explodes, forming many different heavier elements and leaves behind a neutron star.
@@Ominousheat She said at 10:05:: "The ring nebula is the remnant of a star a bit bigger than the sun that has lived, died, and gone supernova about 4000 years ago." My ears are just fine.

Voyager 2 was launched in Aug of 1977 followed by Voyager 1 in Sept. I'm old enough to have remembered it all and thrilled to witness the discoveries as they occurred. I envy those who can witness what new discoveries could be made 30-50 years from now.
Hello Dr. Becky. Thank you for your videos. You really keep my space spark fully ignited. Fun little note for you: PBS Space mentioned you in their video they just released. I do not know if you were aware of it, but I was happy to see that your influence is much stronger than what some people would think. Best wishes and thank you for your information. *edit:* Wow! 100 likes?! Thank you all!
Thanks for this month's space news updates Becky. It amazes me that the remaining power available on Voyager 2 can still be predicted so accurately after all these years. It will be a bittersweet day when this incredible little probe finally falls silent.
@@DrBecky I know I'm gonna cry for a week *at least,* if not longer... 📡〰️〰️〰️🛰️ She's a tough ol' bird. Hardly workin', but still workin' hard. I'm gonna miss you, V2.❤
The Voyagers use radioisotope thermal generators which rely on radioactive decay to produce heat which is then used to generate electricity. The half-life of the isotope used is well known so it’s actually easy to predict when the available power will drop too low for the radio transmitter to produce a usable signal.
I will miss Voyager 2 when it quits. It reached Jupiter on the day I began working at JPL. (My job was to design & code the firmware for the Galileo spacecraft's flight computer.) It treated us to a series of pretty pictures that day.
Voyager 2 is one of those things that just felt like it was always going to be there, since it's been there since long before I have. It's hard coming to terms with the fact that the spacecraft we love are eventually going to die.
thank u for such work, Galileo did so much for space sci and impressing ppl about space as well. Iirc, i saw the program about Galileo's history and it's the most poignant docu of its type i've ever seen, bar none.
What's really crazy is that once Voyager goes silent and loses power, the satellite itself will keep travelling somewhere out there in the void of interstellar space. Long after humanity is gone, it's probably still going to be out there flying on its own as a legacy of one ridiculous planet and species. Truly mind boggling to think about.
@mrgalaxy396 The universe is mind boggling! It's amazing like yourself! I love the fact the old thing is still out there surprising the world and it will until it can give no more and then it will STILL be out there, just in case it runs across someone/something...... Don't count out the old stuff with out of date technology, might just surprise ya when you least expect it! Be safe out there and have a wonderful day!!
I like the idea of V2 someday crashing in the garden of an alien house owner - without hurting anyone of course. I wonder what 'What the heck' sounds like in whatever sort of language they have 😆
Sounds like a Star Trek movie... ;-) but yeah, it and its sibling once depleted will end up being a "we are here" flag! One wonders if the moment will ever come that we'll see them again.
I saw a ton of meteorites this weekend. The weather wasn't the best, but even through high wispy clouds I saw a number of large arcs. Still a few stragglers, but much more quiet. Thank you for this news. It's so nice to hear astrometric news.
I got to see the perseid meteor shower last weekend thanks to last month's space news! It was the night before my birthday, so I convinced my sister to drive up to the local skywatching spot with me shortly before midnight, and it was magical. We were lucky and the skies were really clear that night, we saw at least 20 meteors, and really beautiful ones too. Especially as a physics student and aspiring astrophysicist, that was the perfect birthday gift. Thank you, Becky!
I'm sure a few others have already pointed this out, but the voyagers were both launched in 1977. Probably just a typo on your end. Super love your videos and the awesome science you are always talking about. Please never stop doing this. We are all fascinated! ❤
As a former navigator (C-130), who navigated using a sextant (before GPS), I’d like to add to what Dr. Becky was discussing with the distance of Voyager from earth, and how accurate your signal has to be. We had the 60-1 rule, where 1 degree off would be 1 nautical mile off for every 60 nautical miles travelled. The display at 21:40 shows Voyager about 19.7 billion kilometers from the earth, so 2 degrees off at 18 billion (lazy math for me) means it was pointed over 600 million miles away from earth. That must have been some shout by that station to get Voyager’s attention!
That's true, but there are a few other factors to consider. Here on Earth we knew pretty much exactly where Voyager was at the time, and we could throw a helluva lot of power into that transmission. In order for Voyager to receive any signal it uses a parabolic reflector to concentrate the signal onto its receiver. By throwing more power into the transmission from earth we increased the chances that the parabolic reflector would get some of it into the receiver even though it wasn't pointing directly towards us. Voyager has the opposite problem. It didn't know where we were, and even though we use much more enormous parabolic reflectors to concentrate its signal, being 600 million miles off means our antennae are utterly incapable of recognizing its comparatively weak signal scattering from the incorrectly pointed transmitter. Think of it like a boy with a flashlight on the beach. If you're a mile away from him and he points it right at you, you can probably make out a light. But if he points it even a couple degrees off you'll be unable to see it. Even if you've got big binoculars. But if you've got a _search light_ turned up to 11, he can probably see you if he's pointed those same degrees off to the side, even without binoculars.
What if the “Wow!” signal was some other civilization’s instructions to its Voyager 2 that was two degrees off for a hot second, and we just happened to be in the line of fire?
Thanks as always Dr Becky for all you do especially for us lay people, it is one of the great things about the interweb but you still need someone to be generous with their time and expertise. JWST is finding things that are simply mind blowing for my limited understanding anyways. The finding of water vapour is seriously big news. - (I think). That they can communicate with voyager 2 amazed me I didn't know it was even possible and the shout thingy and the foresight I am lost for words.
A preemptive thank you for your attention to detail and commitment to high quality content that leads to the two mentioned upcoming videos regarding the 'dark stars' papers, and not just rushing to throw minimal details into this regular release
Switched on the TV the other night and who should I see on 'The Sky at Night' ? None other than our very own favourite Dr Beck's!! Pretty cool segment btw. I enjoyed the projections on the brick wall illustrating your descriptions! 👌👍
I love you Dr. Becky. You are so informative without being condescending. You have a lovely accent, such a pretty face, and such a warm endearing personality. Thx for all you do
Dr. Becky's just the bomb! Great smile that runs right through her voice, coupled with a bright mind and an exceptional ability to communicate with everyone. Thank you Dr. Smethurst.
Always awesome, how passionate you are about space news and to present it so pleasantly to your crowd of admiring followers, Dr. Becky! Including the lovely bloopers 😎🫶🇩🇪🙏
The JWST color team is on point. I’m happy that false color images have gotten beyond the primary colors. They should be beautiful, and they deserve the eyes of an artist.
7:57 L2 (along with L1 and L3) is a gravitationally UNstable point. That's why spacecraft have to periodically adjust their orbit to stay there. L4 and L5 are gravitationally stable points. L2 is a very gravitationally flat area so while objects always drift away from L2, they do so slowly. Objects don't have to use fuel to stay at L4 or L5, but because of this there's lots of captured rocks and debris already there.
Evening Dr Becky, loving the stream and loved the book! I'm always up for some Voyager news. Random question - what might it look like these days? Still box fresh like in the animations (because space is largely empty), or ragged and full of holes (because it's been on the longest journey in human history)?
It's got a few tiny holes from micrometeorites but is otherwise fine; remember it's going through space not a woodland. :P There's next to nothing out there, and most ahat there is is tiny or microscopic.
I would suggest that is still to be determined. As far as I'm concerned the Apollo program is still the greatest, followed closely by the Voyager program. Coming in at 3rd and only slightly behind the Voyagers are the Mars Exploration Rovers. They both started off to run the 400 meters, but ended up running two back-to-back marathons. Armstrong and Aldrin landed on the moon and came back basically with the technological equivalent of stone knives and bear skins. Apollo 13 came back from a disaster with less than that.
Isn't the ring nebula a planetary nebula? Aren't those the leftovers of smaller stars that become white dwarfs and therefore don't go supernova? From the description you give, that's what it feels you meant, but accidentally used the term supernova, am I correct? I do understand that when recording, the mouth says things that were not meant sometimes... it definitely happens to me all the time.
I watch your videos with my 3 year old daughter. She loves the pictures. It's so nice to have female role models in the sciences, especially for space.
I really appreciate the effort you expend making these videos so useful with chapter marks and just your general organization. You (and your crew?) are doing an excellent job. I just checked out an old video (actually an interview) that I was able to find because of these organizational extras accessible to search engines. #FeedTheAlgorithm
There is no one better than you. We can understand so much from your videos. Thank you so much. Please keep up your fantastic work. Live long and prosper 🖖
@@alankilgore1132I’m not sure it even went nova. I think this is just the expelling of the star’s outer layers during the pulsing of the red supergiant phase.
Seconding this. Wikipedia refers to the stellar remnant in the Ring Nebula as a white dwarf, stating: "within the last two thousand years, the central star of the Ring Nebula has left the asymptotic giant branch after exhausting its supply of hydrogen fuel" and "it is now becoming a compact white dwarf star".
What completely bows me away is the complexity of the maths that must go with tracking and communicating with Voyager 2. Glad there’s people out there that paid more attention than I did during high school maths class.
10:08 I’ve always been taught that the precursor to a planetary nebula is always a star lower than about 8 solar masses which means that it can’t and won’t undergo a supernova explosion. It does expel a lot of matter-creating the nebula-but not in a cataclysmic implosion/explosion event.
Your video making skills have really come on in leaps and bounds Dr. Love the new natural colour grade and the frame motion. Great supporting graphics and visuals too. Yours is truly one of the great science news channels. Between you, Sabine and Anton, I feel totally up to speed. I really enjoyed your CERN tour video. Please take us with you again next time you go somewhere amazing like that!
Some of these bloopers were particularly funny! I love that you said what I was thinking [nice nail polish!]. Also enjoying the slightly more casual speech. Thanks!
4:33 I learned how to find most planets that can be seen naked eye long ago from some astronomy book I found on my granmother attic. I was 10 or something. it was not so hard to learn but I was so proud of this skill. I'm still proud. Totally worth it.
6:35 😅 I do believe that is the first time I have heard you swear on Night Sky News... I don't know why but I found it VERY entertaining... ... Down the rabbit hole again
Been watching you (now that sounds creepy) develop your channel over last few years. Love the content and your "laymans explanations", I don't have enough time myself at the moment to explore this stuff myself. I look forward to your videos, space talk, lovely smile and humour :D
What's amazing to me is that (until gravitational wave detection), everything ... every single thing ... we know about the universe outside our solar system has been determined by looking a light. Just "light rays of certain colours" (yes, I'm including X-rays and IR here). The big bang, inflation, star growth, black holes; all of it from just studying "coloured light" (obviously with hugely successful theories used to make predications about it etc.).
Looking forward to your video about testing MOND with WB, Dr.! In the recent conference celebrating MOND's 40h anniversary, these blessed crazies had a lot of fun discussing this business: two talks finding no hint of MOND, just old Newton, and two talks claiming a clear MONDian signal.Some people even went with popcorn to the discussions...
Great Gratitude to you Dr Becky... 28 minutes of astrophysics information and I am ready to listen to another 28 minutes or much more!!! Bravo Bravo Bravo Thank You...Thank You
Love the shirt 👕 Please ask Megan to give us versions that are printed on the back! with something small on the front. 🧙♂️ For those of us who aren't as pleasant to look at as you 🤭
the best stargazing of my life was when I lived in the countryside of guatemala. the small town there had no power at night so zero pollution. The sky was so bright though just from the stars. I lived there in the 90s and got to see Hale-Bopp comet too. Makes me want to go back.
I realized I hadn't yet thanked you for the binocular and camera recommendations. Not this week, but the week before, I went on vacation to a fairly remote area. I was able to capture some images that were very satisfactory, especially for someone just entering the astrophotography field. With binoculars I was able to point out several objects to my partner and let her appreciate them. To see the clouds of our galaxy resolve into seemingly inifinite starfields was worth the trip and the expense. Thank you again for reawakening my old nerddom obsession and improving my appreciation for it.
Hi Becky - isn’t the ring nebula a planetary nebula? from a dying sun-like star that’s puffed off its outer layers and left behind a white dwarf. Not from a supernova. Love your work!
I finally got to watch The Sky At Night and there is a familiar face! So cool! I love your show and I have been watching The Sky At Night as long as I can remember.
Dr. Becky, when your schedule next slows enough to allow it, I hope you'll consider giving Star Trek the Next Generation a do-over? If you choose to, please consider Season 5 Episode 25, "The Inner Light". I'd very much enjoy hearing you talk about the ways stars have influence over the planets that orbit them.
A fun video as Dr. Becky's channel usually is. However the last part about Voyager 2 was a bit of a shock. I remember when Voyager 1 and 2 were launched. I remember when they arrived at each planet and eagerly looking for the photographs they would send back. And then I realized Dr. Becky is younger than Voyager, a lot younger. I'm old....
This video is a prime example why you deserve to name your book simular to another exceptional individuals book, because you explained all of that so a simple person like me could understand it. Big thank you for great and informative videos.

It's fascinating learning about the amazing work these people are doing. Thank you for sharing that with us!
I'm addicted to your enthusiasm, finally someone as excited as I am about good ol nerdy science.
Evening Dr Becky, loving the stream and loved the book!
I'm always up for some Voyager news. Random question - what might it look like these days? Still box fresh like in the animations (because space is largely empty), or ragged and full of holes (because it's been on the longest journey in human history)?
It's got a few tiny holes from micrometeorites but is otherwise fine; remember it's going through space not a woodland. :P There's next to nothing out there, and most ahat there is is tiny or microscopic.
i figure it could be a bit dulled and darkened by all the cosmic rays and diffuse gas
Thanks a lot Dr. Becky, another wonderful video full of news and really great comments from you !!
Is JWST already one of the greatest space missions of all time? The discoveries are just mind blowing.
I would suggest that is still to be determined. As far as I'm concerned the Apollo program is still the greatest, followed closely by the Voyager program. Coming in at 3rd and only slightly behind the Voyagers are the Mars Exploration Rovers. They both started off to run the 400 meters, but ended up running two back-to-back marathons.
Armstrong and Aldrin landed on the moon and came back basically with the technological equivalent of stone knives and bear skins. Apollo 13 came back from a disaster with less than that.
Love the frame of 7:36 :D
I was looking for meteors the other night and I definitely saw the milky way but I wasnt sure if it was possible to see with your eyes
It is! 🥳
it's possible without city light pollution or stuff like that
Highly visible so long as it's not washed out by light pollution
Thanks Dr. Becky I learn new things from every new video.
Isn't the ring nebula a planetary nebula? Aren't those the leftovers of smaller stars that become white dwarfs and therefore don't go supernova? From the description you give, that's what it feels you meant, but accidentally used the term supernova, am I correct? I do understand that when recording, the mouth says things that were not meant sometimes... it definitely happens to me all the time.
I watch your videos with my 3 year old daughter. She loves the pictures. It's so nice to have female role models in the sciences, especially for space.
I really appreciate the effort you expend making these videos so useful with chapter marks and just your general organization. You (and your crew?) are doing an excellent job. I just checked out an old video (actually an interview) that I was able to find because of these organizational extras accessible to search engines. #FeedTheAlgorithm
My favorite is the Blood Wolf Moon we had here in South Carolina a few years back. Easy to photograph too.
I remember when the Voyagers were launched, I’m glad that we’re still around.
Me too (I was 10 years old in '79). News about them makes me feel very humble, small in a Big Universe.
@@jeroenrl1438, I wonder how those probes would be constructed now and how long would they last?
Yeah. I was 25 when they were launched. Lucky to still be here. Both of my friends have sinced died.
@@robertvarner9519, sorry about your friends.
There is no one better than you. We can understand so much from your videos. Thank you so much. Please keep up your fantastic work. Live long and prosper 🖖
10:03 since the ring nebula is a planetary nebula, wouldn't that mean the star became a white dwarf instead of going supernova?
You are correct. Not sure why Becky didn't catch that one. The star went "Nova", just as our sun will later in its life.
@@alankilgore1132I’m not sure it even went nova. I think this is just the expelling of the star’s outer layers during the pulsing of the red supergiant phase.
Seconding this. Wikipedia refers to the stellar remnant in the Ring Nebula as a white dwarf, stating: "within the last two thousand years, the central star of the Ring Nebula has left the asymptotic giant branch after exhausting its supply of hydrogen fuel" and "it is now becoming a compact white dwarf star".
What completely bows me away is the complexity of the maths that must go with tracking and communicating with Voyager 2. Glad there’s people out there that paid more attention than I did during high school maths class.
6:32-6:39 YES! Thank you for saying this!
10:08 I’ve always been taught that the precursor to a planetary nebula is always a star lower than about 8 solar masses which means that it can’t and won’t undergo a supernova explosion. It does expel a lot of matter-creating the nebula-but not in a cataclysmic implosion/explosion event.
Keep looking up Dr. Becky ✨👍
Your video making skills have really come on in leaps and bounds Dr. Love the new natural colour grade and the frame motion. Great supporting graphics and visuals too. Yours is truly one of the great science news channels. Between you, Sabine and Anton, I feel totally up to speed.
I really enjoyed your CERN tour video. Please take us with you again next time you go somewhere amazing like that!
I mean this in the most purest way possible, I love you. You are awesome.❤
P.S. Thanks for the bloopers.
Dr Becky, I love the universe in your eyes!
Some of these bloopers were particularly funny! I love that you said what I was thinking [nice nail polish!]. Also enjoying the slightly more casual speech. Thanks!
4:33 I learned how to find most planets that can be seen naked eye long ago from some astronomy book I found on my granmother attic. I was 10 or something. it was not so hard to learn but I was so proud of this skill. I'm still proud. Totally worth it.
Thanks for the news Becky!
Thanks for watching 🤗
Thanks a bunch for all the news, dr. Becky! 😊
Stay safe there with your family! 🖖😊
I definitely stay for the bloopers
Your production quality has exploded this year. Great work!
6:35 😅 I do believe that is the first time I have heard you swear on Night Sky News... I don't know why but I found it VERY entertaining...
... Down the rabbit hole again
If you are going to swear at anything, swear at pseudoscience. 🔥
Come for the space, stay for the bloopers - love it. Keep it up Dr. B! it's great to see this.
Camera upgrade and change of background are very nice! And you look great! And, as always, thank you very much for another portion astro news
Indeed, come for the space, stay for the bloopers, especially the random songs you throw in.
Been watching you (now that sounds creepy) develop your channel over last few years. Love the content and your "laymans explanations", I don't have enough time myself at the moment to explore this stuff myself. I look forward to your videos, space talk, lovely smile and humour :D
I never skip over parts of your videos, your opinion is more than worthy of my attention lol.
I love that upfront "hellooo & welcome"... It's like a song.
Looking fwd the Mod Grav vid
I thought it was pretty awesome that PBS Spacetime mentioned your channel recently 🙂
We come for the space, and we stay for the bloopers.
What's amazing to me is that (until gravitational wave detection), everything ... every single thing ... we know about the universe outside our solar system has been determined by looking a light. Just "light rays of certain colours" (yes, I'm including X-rays and IR here). The big bang, inflation, star growth, black holes; all of it from just studying "coloured light" (obviously with hugely successful theories used to make predications about it etc.).
New subscriber, just wanted to say thank you for a brilliant vid. I love astronomy and your delivery is fun and bubbly.
Thank you Dr. Becky!
Ahhhhh I am too excited for those upcoming videos!
Thanks so much for these vlogs. Amazing content!!!!!!
Ive been hooked on your videos!
Your way of presenting is so palatable especially for people (me) who are new to this space. Pun unintended hehe
Looking forward to your video about testing MOND with WB, Dr.! In the recent conference celebrating MOND's 40h anniversary, these blessed crazies had a lot of fun discussing this business: two talks finding no hint of MOND, just old Newton, and two talks claiming a clear MONDian signal.Some people even went with popcorn to the discussions...
Hi Dr Becky. Love watching your uploads and don't usually leave a comment... so just wanted to say Hi 👋and thank you for everything you do. 😆
Great Gratitude to you Dr Becky... 28 minutes of astrophysics information and I am ready to listen to another 28 minutes or much more!!! Bravo Bravo Bravo Thank You...Thank You
Thank you Becky 🙏🙏
You rule! I love listening to you talk!!!! ❤
Wow. So intelligent & so passionate. Love it. Thanks.
Love the shirt 👕
Please ask Megan to give us versions that are printed on the back!
with something small on the front.
🧙♂️ For those of us who aren't as pleasant to look at as you 🤭
Thanks for sharing DR. Becky
the best stargazing of my life was when I lived in the countryside of guatemala. the small town there had no power at night so zero pollution. The sky was so bright though just from the stars. I lived there in the 90s and got to see Hale-Bopp comet too. Makes me want to go back.
My goodness, you are communicator with such clarity...Im not from a science background but love astronomy,,,just fantastic!
I realized I hadn't yet thanked you for the binocular and camera recommendations. Not this week, but the week before, I went on vacation to a fairly remote area. I was able to capture some images that were very satisfactory, especially for someone just entering the astrophotography field. With binoculars I was able to point out several objects to my partner and let her appreciate them. To see the clouds of our galaxy resolve into seemingly inifinite starfields was worth the trip and the expense. Thank you again for reawakening my old nerddom obsession and improving my appreciation for it.
sooo cool and awe-some.!
That sounds like an exciting month for news. Thank you.
Geeze I LOVE your channel. Thank you!
Hi Becky - isn’t the ring nebula a planetary nebula? from a dying sun-like star that’s puffed off its outer layers and left behind a white dwarf. Not from a supernova. Love your work!
I finally got to watch The Sky At Night and there is a familiar face! So cool! I love your show and I have been watching The Sky At Night as long as I can remember.
Dr. Becky, when your schedule next slows enough to allow it, I hope you'll consider giving Star Trek the Next Generation a do-over?
If you choose to, please consider Season 5 Episode 25, "The Inner Light".
I'd very much enjoy hearing you talk about the ways stars have influence over the planets that orbit them.
A fun video as Dr. Becky's channel usually is. However the last part about Voyager 2 was a bit of a shock. I remember when Voyager 1 and 2 were launched. I remember when they arrived at each planet and eagerly looking for the photographs they would send back. And then I realized Dr. Becky is younger than Voyager, a lot younger. I'm old....
Thanks for making this video.
Thanks for the update, all the best from the west Highlands of Scotland
We love this channel! ❤🎉😊
Thanks! 🤗
This video is a prime example why you deserve to name your book simular to another exceptional individuals book, because you explained all of that so a simple person like me could understand it. Big thank you for great and informative videos.
