Eta Carinae is the closest, best known, and most studied of the stars known as "supernova impostors". After surviving a supernova-like brightening in the 1840's, Eta Car faded away for the rest of the 19th century, and slowly grew more luminous over the 20th century. Modern observations across visible, ultraviolet, and x-ray wavelengths reveal complex, nested structures of gas and dust that resulted from the 1840's Great Eruption and other outbursts from this massive star system. Dr. Summers will showcase a 3D visualization of these nebulae as well as delve into the colliding wind binary star at the core of this remarkable celestial object.

I could listen to Frank Summers all day long. This is a great presenter and a man who found his calling.
We are watching you from Greece and we totally thank you for the amazing lectures. You help the world to learn
I would suggest adding the scale of the homunculus nebula. Great lecture! Thanks for your work and keeping the public a part of the exploration of the universe.
14:50 Yes, between those two there is a third "cross" called "The Diamond Cross" that has a cool open cluster (IC 2602, known as "The Southern Pleiades") In this photo it is seen in the center of the orange arrow used to point the EC nebula at 15:37
Well worth watching, and again. Thanks.
I take this video as another support for my guess that eta Carinae will be the first science image of the James Webb Space Telescope. Anyone have any other favourite objects you think could be the first image?
Gum 29 nebula / Westerlund 2 (Hubble’s 25th anniversary image & Dr. Summers “Celestial Fireworks” visualization).
Thank you Dr. Summers. I think your visualizations are beautiful and amazing. As a 30+ year graphic designer who is obsessed with space, creating these visualizations would be my absolute dream job. Thank you for the video interviews.
Great talk.
Thank You!
Great speaker! 😎😎
Dr Summers I have a question, as going deeper into space we observe light from 'younger' galaxes because the light from their childhood just arrived to us at the moment of the observation, but why we can not observe light from the very distant deep space from other object when they were 'old', those old object should be next to the young one otherwise we must assume that at the point in time when light from that deep region was sent to us there were only new born galaxes right? Is that assumption correct? And why doest it happen that way that all galaxes in the particular time and region was born at the simmilar time? How come we can not see the mix of the light from old and young objects at the same time?
I love the guest presenters, but I'm subscribed for those from Dr. Summers. This one surely did not disappoint! I loved every second. If possible I'd suggest the description be updated to link to the Universe Unplugged version of the video as the embedded version from this talk has a lot of frame drops th-cam.com/video/5Peg7hwuH9E/w-d-xo.html&t
Our host has been doing this (show?) for 20 years and got his UG from VPI !!!
Isn't that music from the Tangerine Dream band's phaedra album ? 56:30
55:21 ETA CARINAE - The Great Eruption of a Massive Star - The Movie
Stunning - how do you get involved?!!
Question???
Would Spitzer still be functional if it didn't lose so many reaction wheels?
Would it have exhausted it's helium supply by now???
7:45 Yes, but r those images really the raw data, or have any artist clean them up? Since u know most space pictures we get to see have been edited to look better.
The Cosmic Background Radiation Ambient Noise map shows us the density of galaxies when we observe the universe from the earth. There more galaxies in red spots and less in the dark areas.
the noise is not the left over of big bang, but the collective noise of galaxies. see Hubble's UItra Deep Field. When James Webb telescope is ready, we can find a black spot in Hubble's UItra Deep Field to have long long exposure picture, what we will have is Webb's UItra Deep Field, repeating Hubble's UItra Deep Field patent.
The big bang is very suspicious, to me, the redshift is caused dark matter and dark energy, not by galaxies moving away from each other. If the universe were expanding faster and faster, galaxies would move away from each other, at one point, galaxies would stop collations. But the collations happened, are happening, and will happen for ever.
The arms of a galaxy indicate how many collations that galaxy has gone through. No arm means original galaxy. The arms and sub-arms numbers (N-1) tell us how many collations that galaxy experienced. Two arms, one collation. Two main arms, one of them with a minor sub arm, three collations; formed by one galaxy and one galaxy had prior minor collation. The galaxy can't grow infinitely, when the mass go beyond certain amount, the core will explode.
The universe is isotropic. To the people live at the end of James Webb telescope can ever reach, think that we are as old as we thought they are.
dark matter and dark energy caused red/blue shift, not galaxies moving. black holes can hold certain amount of matter, go beyond that, explosions happen.
e=mc2 may be right may be wrong, it could be e=mc3 or 4 or 5, or 2.71828,,,,or 3.1415926,,,,
