The Homunculus Nebula is about 0.6 light-years across. Hence, each lobe is about 0.3 ly in diameter. To expand to 0.3 ly in 200 years requires an average velocity of about 500 km/s ( roughly a million miles an hour).
That is the best CGI yet of a star going though a time period that is exciting to see and understand and it is the real deal. I still find Hubble's Ultra Deep Field image as the most incredible.
This is why we do science! I just hope that Eta Car blew itself up a long time ago, and that the light from the supernova will hit earth at any moment. I could die happy then. Thank you to all involved in making this, you are the true heroes of the universe.
Thank you to the team at STSI. That was fantastic. For the last few months I had wondered what this star would look like if we could get JWST to look at it. Now I know it would be a useless to try. Considering how much IR light the star emits.
Up until today I though this star already underwent a supernova in 1843, but now I understand it was just some kind of precursor event that has happened multiple times before. What's the homunculus nebula made of? I imagine it can't be anything heavier than iron as you need a proper supernova for that.
Fascinating stuff! Love the imagery. I am curious though. I am far from an expert, just someone who has been interested in space since I was a kid many years ago. It hasn’t gone supernova yet, so what processes are thought to have caused this huge explosion? I’ve never really heard of anything that could happen to a star, other then going Supernova, that could cause something like that!
Absolutely luved it. It's amazing to think that all (In therory because there could be an exception to the notion that is beyond Human comprehension of thought!?!) Stars end their lives via this similar process. In death the is life "A star dies, ✨A new star is born" Higgs boson! The music 🎵🎶🎵 in this🎥 was spot on. Brilliantly attributed!¡!¡!
I'd love to have a better appreciation of the time and distance scales represented in these video clips. Does the depiction of the future collision of Andromeda and the Milky Way Galaxies take Billions of years? Tens of Billions? more? How fast do you have to be traveling to cross a galaxy in a matter of seconds? The numbers, even though hypothetical, would be fascinating to contemplate and would give a better understanding of what we're looking at.
If I can get permission to travel, I should be bringing a fulldome version of the 3D model spin to your planetarium for the MAPS conference in May. I've produced a preliminary version for AAS in Salt Lake, but that was cancelled.
We will never know how powerful can be the known Universe... We are only seeing light side of it. Not anymore. Cause we are human beings, not anything else..... MYSTERIOUS WORLD. 🌐👍🐱⭐⭐⭐⭐💥💥
Probably not. Estimates vary, but even a Long GRB from 4k lightyears wouldn't strip the ozone layer away completely. Thankfully, eta car is 7500 lys away.
You guys are the worst thing ever for the newly legalied Canabis Industry because you show that study, knowlege and discipline can give one the same "Wow High" at no cost not any neuro/pulmonary damage. Ubdistorted reality is still the biggest high, especially when so well and enthusiastically explained. You oboth are exceptionl Homo sapiens...and I can say that as a life-long student of thr species. The world "professor" will never sound the same to me ever again. Thanks!
It is the brightest object in the night sky because it is the brightest object which we can see in the sky during the night, the Sun being the brightest during the day. The statement does not mean to convey that it is night there, of course.
That zoom in was almost like a spiritual experience. Truly awesome.

Hi everyone, I'm the leader of the team that created this video. Thank you for watching, and I'll answer your questions about it as time permits.
Eta Carinae is about 7,500 light-years away.
The Homunculus Nebula is about 0.6 light-years across. Hence, each lobe is about 0.3 ly in diameter. To expand to 0.3 ly in 200 years requires an average velocity of about 500 km/s ( roughly a million miles an hour).
Well done, an excellent presentation! Thanks
@@FrankSummers Okay, so do you know How big was Eta Carinae during that Great Eruption? I Heard about 1400 Rsol and 4900 Rsol
So it would take around 154 days for the expanding cloud to reach pluto from the sun. Thats fast!
Very cool! Nicely done on this one--short and sweet, with a lot of cool information. Eta Carina is utterly fascinating.
Incredibly well done , beautiful images and also very interesting comments . I was glued to my screen for a moment .Thank you

I'm 55 been into astronomy 40+ years..eta c is my favourite neb.truly awesome....what's the webb..gonna show us....I can't wait...thank you so much🖖👍🙏
Thank you. That was both intellectually and artistically satisfying, and adds to my sense of wonder of the cosmos.
It's absolutely dazzling. Thank you for the excellent model
Wow, that cgi of the blast was amazing, this is an awesome way of learning about our universe. Thanks so much.
Amazing to watch! The best video-made Vista of ETA CARINAE so far!
Thanks!
Both the star and the video itself are amazing. Thank you.
Fantastic production

It's more than 7000 light years ahead it can't do any wrong to our solar system

It's a because Eta Car is an example of an LBV - a really weird variable star
The Carina Nebula is so pretty!
Most beautiful ❤❤❤
Incredible, thank you One Love from Portugal.
Excellent video thanks. Super Nova in the next few million years? I'll get me Popcorn lol.

I can only imagine how rich those clouds must be with heavier elements. Ripe for mining or perhaps some day to form lively planets.
Love it. Thank you NASA!
AWESOME. Exploding stuff.
Very good view.thanks.
Utterly Amazing
my first comment, and gotta say best video i've watched so far
We are made in His image.....awesome
Amazing Hubble Space Telescope
Fascinating! 🤩🤯
Thanks a lot!

So what is the size of the nebula?
η Car; the enigmatic ⭐
Nice
Need a fulldome version of this for planetariums!

@@FrankSummers that would be wonderful! Hope to see you here in Maine in May!
Telescopi Hubble?
If only I could buy space a beer and ask it some questions.
Quanti anni luce è distante dalla Terra
7,500 light-years
Wow7,500 light year
I wonder how Astronomers explain why stars explode in hourglass shapes instead of spherical shapes.
We will never know how powerful can be the known Universe... We are only seeing light side of it. Not anymore.
Cause we are human beings, not anything else..... MYSTERIOUS WORLD.

Awesome to. See my mighty gods hand at work
Thank God this thing is far away from us.

I actually viewed the star system, the fact that a gamma ray from this star system would kill all of us is very scary
Probably not. Estimates vary, but even a Long GRB from 4k lightyears wouldn't strip the ozone layer away completely. Thankfully, eta car is 7500 lys away.
There was no sense of scale. Perhaps you could add one.
I was expecting to see how many light years across the nebula was.
I answered your question in the replies to my comment. Basically, Eta Car is 7500 ly away, and the Homunculus is 0.6 ly across.
@@FrankSummers Thanks!
wow
I'll show you a great eruption alright!

AND NO REAL PHOTO OR VIDEO EVIDENCE OF IT,insane
There are plenty of real photos out there. Plus you can just grab a telescope and see it yourself

Eta carine more ike eat a car

Why do you say it's the brghtest object in the "night" sky? It's not night there. lol
It is the brightest object in the night sky because it is the brightest object which we can see in the sky during the night, the Sun being the brightest during the day.
