I’m 70 years old now days and live in deep poverty area in the southern Philippines. Thank you for playing your part in making the world a better place,you are so very kind natured and love to listen to you on the edge of my seat. God bless you young man 👍
Awesome!
Congratulations for 25 years of great work. Here's to another 25!
When I visited Australia from the US we went to a dark sky location to see the milky way (MINDBLOWING), but I was pointing out Orion to my GF and suddenly realised it was upside down, really blew my mind realising that, finally converted me from a flat earther (only kidding) but just rocked my world seeing that, may not sound amazing but seeing it IRL and realising my position on the planet was giving me this new perspective really put things in, err, perspective.
And your Upside-down to me is the only way I've ever seen it. Hope to be in the north one day to experience it the other way too.
Congratulations on doing what you do so well for 25 years. Good to go for another 25.
Congratulations on a quarter century Fraser & universe today team! You know the old saying "Bulls of a horn flock together!"
Happy 25th, Fraser. I hope I'm able to find that same kind of spark for myself one day, and I'm so glad you did. My life without Universe Today would've taken a totally different course, and I'm convinced it would've been a worse course, because that's just the quality of content we're talking about here. Here's to many more 🎈📡🔭
Congratulations for the 25 years of devotion. You're amazing.
Congratulations Fraser! You are doing a fantastic job. Please keep it coming. 👍
🎊🎉✨🎇🌛happy 25th Fras..🎆🧨⚡🌟⛅🌜⭐
Happy anniversary. 25 years is a long time. Thanks for all you do
Huge congrats on the anniversary Fraser. Universe Today is amazing - thanks to you and the entire team for the entertainment and learning I get here
Congratulations, and thank you for bringing the cosmos into focus for us all! Your dedication to this subject matter has made a huge contribution to my knowledge...and many many others I'm sure would attest the same thing! Seriously, thank you very much for what you do! You HAVE made a positive contribution to this world!! ❤❤
Congrats on 25 years!
Always love this channel.
Hey Fraser! Thank you so much for the shout-out and for all that you do; Truly top tier science journalism. And Happy 25th Anniversary to Universe Today!
Thanks! And keep up the good work!
Great episode again Fraser! Congratulations on 25 years UT!
You are hilarious today Mr Universe.
The equatorial crescent Moon will now always be a ‘The Balls of a horn’ moon.
I spat my cuppa tea across the kitchen table and laughed so hard. Thank you, you made my day !
I've often wondered about moon moons myself 😅
Moon-Moon
'Bulls of a horn' passed through my brain as an entirely normal phrase, and it's only when you corrected yourself that I realised 😂
Fantastic achievement! Thank you so much for your work🎉
Congrats! My child is 25 years old... and so is yours
Cait. Congrats on 25 years, and thanks for sharing your story of following your passion. :)
Southern hemisphere stargazing is on my bucket list
Your enthusiasm for astronomy is contagious! From discussing potential Moon moons to the practicalities of space travel, this episode was both informative and inspiring. Can't wait for the next one!
Happy Anniversary. I like your channel.
Happy anniversary! Universe today (and all you do) is a big part of why I love space. Here's to 25 more!
Happy 25 years of Universe Today, Fraser! 🎉
Congrats on the 25th birthday Universe Today!
Congrats Fraser you're incredible!!!!!!
Vendiker, 25 yrs of space journalism is amazing. Congratulations!
0:32. Congrats!! I was 14 when you started. Glad you went this direction and stuck with it!
Thank you and your team for 25 years of journalism excellence. Your hard work and dedication to the high quality standards of both science and journalism has given you a reputation in both communities as a trusted and reliable source of contemporary science and space stories. Congratulations, and thank you.
Risa was my fav this week. Congrats on 25 years Fraser. Having Universe Today remain relevant through all the changes in how people learn and consume information is a true feat.
Andoria. Great question and great answer.
Congrats on 25 years! Going strong!
When you were talking about what you can see in the southern hemisphere you left out the Great Southern Cross. The first time I saw it I was stationed on a US Guided Missile Frigate on our way to Australia. The size is amazing.
I loved going out on the weather deck after midnight out at sea and watching the sky. Particularly in the Pacific Ocean, hundreds of miles from any land. On a clear calm night there is nothing like it❤❤❤
You’ve been a blessing in this world for 25 years
Congratulations on a quarter century of excellence! Cheers mate!
Congratulations on your 25th anniversary of starting Universe Today.
Today's episode is one of your very best for teaching us fundamental concepts. I learned so much. Thanks.😊
Congrats for unveiling the universe to the masses for such a long time, since the last millennia. Keep going far into the future.
Congratulations Fraser on your 25th anniversary! Wow, what an achievement! Fantastic!
I began listening to you on the early iTunes podcast around 2002 I think. It’s when you did a weekly audio show with a lady astronomer and I remember I had over 200 episodes on my titanium Mac laptop- and I still have it on life support?!
This was a great week! 👍🏾
Thank you for 25 years
YAY !!! So good. May the next 25 years bring us all more awesome news. ❤Keep on rocking and break for nobody. 😊
[Andoria] Best answer of the week.
The orientation of the crescent Moon changes even when you stay in the same place. There is a folk tale that drought is caused when the Moon "holds water," that is, looks like a bowl held horizontally. When the Moon bowl is tipped so the water can flow out, the rain will come.
During the 2012 Tulum cruise, I remember you mentioning the moon being in a different orientation because we were so far south and I was like, "Uh, I guess? A little?" Then I realized you were speaking mainly to people who didn't already live around 30N and the difference was much more significant to you. XD
Little late to saying this but congrats on 25 years. Your content is stellar glad I found you earlier this year.
Gratz on 25 years Fraser! Love your work mate
Congrats with such a significant anniversary. That was great, we liked it
Congratulations, Fraser. Great job, thanks for all the excellent reporting.
Congrats Fraser
And thank you to you and your team for all that you do
Wow congratulations 🎉 I’ve been watching you for over 23 yrs
Congrats on your 25 year anniversary!
One of the highlights of a trip to Buenos Aires for me was seeing Alpha Centauri for the first time. I didn't even realize at first I was looking at it, until I saw a bright star, and then saw Crux and realized where I was looking. Ironically enough a few months before that I'd gone to Hawaii for the first time and it was pretty cool to see so much of Scorpio.
Thank you Fraser for answering our questions, from stupid laypeople, in an understandable manner. Your pedagogy is exceptional.
From Ushaia, Argentina, I got to see the moon looking fully upside-down. I knew it would do that but it was still very weird to see.
Cait was the best question, cool to learn about your history and congratulations on 25 years since the website!
You should do an anniversary show with the most exciting events over the past 25 years
Congrats! You're the best out there!!
Ansonia: really good question!
Great answer. Super detailed and thorough , as usual.
Great videos. I am now a regular consumer :) you are so knowledgeable and yet so humble. Huge respect for you ! Keep up the good work.
Congrats on your anniversary!
thank you for your awesome show Frasier
Vendikar
The StarTrek documentary series shows just how we drop subspace beacons all over the place for this purpose.
Is there any chance you could snag Nobel laureate George Smoot for an interview, especially for his work on COBE? Your interviews are outstanding! Congrats on 25 years!
Congratulations on your sites Silver Jubilee!
Congrats on the amazing accomplishment
Congrats man!!!
Happy 25th! Wooooh Hoooh!
Congratulations Frasier! Been listening to you since Astronomy Cast when the iPod mini first come out lol.
Thank you!
I love the way my wife snores. It's so cute. Cute little snore. ❤️
Regarding Laniakea, we have a perfect reference frame - CMB. Our movement in relation to it is measured quite precisely. Without this correction, all measurements of the Hubble constant do not make sense.
Thanks a lot 👍
Risa! Such a cool concept
25 years??? Wow congratulations!!
Happy 25th anniversary!
Cait! Thanks for sharing your astronomy origin story :)
Congratulations Fraser! Here's to 25 more years👍
ConGrats on 25 years!! Wow time fly's Fast and thank you for all your Great information.
Best videos on youtube by far.
Omega Centauri can be seen from the northern hemisphere in May and June. I saw it from The San Luis Valley in southern Colorado around 38 degrees north. A dark unobstructed southern horizon (no clouds, trees, hills, mountains) is necessary.
I'm a big fan of the Plonk-satellite!
Planck satellite gave us amazing Universe information. We need more science satellites and fewer bombs.
Congratulations
Another great TH-cam channel is Graviton Media.
Congrats on the 25th anniversary!
Congratulations 🎉❤,🙌
Aeturen. Never traveled to the other hemisphere, but never thought of it. Totally makes sense.
Remus. Great program!
Aeturen
One can never have too many flat-earth counter arguments.
Hi Frasier, love your channel 😊
Question: would the universe be colder if there had been no stars, galaxy's ect. .??
Congrats on your 25 years ...
Need a 25yr anniversary show! Please your favorite highlights
So many stories. Maybe 30,000 to go through?
I also was inspired by Time-Life The Universe. Really did make you want to build a rocket in your back yard. I'm sure you are inspiring lots of kids in the same way right now.
Wow the show is the same age as me. Well done Fraser ❤
I heared from people like Dr. Becky that we don't really know how the supermassive black holes at the centres of galaxies formed. What's the deal with this? Could you talk about black hole formation for a bit?
Adding repeaters to the deep space network would help - so having a deep space network in deep space would help.
A 70m dish at Mars linked to a 70m dish at Jupiter would change a lot of things.
Space communications....several years ago I recall a new function of TCPIP protocol so that for each "hop" in a series of routers each router would buffer and could re-transmit a data packet without asking the source of the packet to re-transmit. This is a critical step to effective relays. Not sure if this has been implemented or not but like for Mars orbiters that we have today, I would expect the newer ones would be doing this already.
Luna Park trip!!!
Oh nooo.. I almost never comment and never before to disagree, BUT I think the answer about shadows on the moon is.. not right? Just watch the moon over the next year, (you're only slightly further north than me Fraser) you will see we have the smiley moon, a sad face, and the DreamWorks image (minus the fishing kid) from both directions and every rotation.. I think.. it surprised me too, but the realization was a family moment I will not forget.. Love the channel, I watch it all every week, (bring on the NIAC interviews!!) keep up the amazing work 🙂
Thought about it.. could it be due to the angle of the moon's orbit relative to our solar plane..? When it's low in it's relative inclination we would get the happy face??
25 turns around the Sun!!!!! Congratulations!!!!
