Celestial Fireworks: Hubble's Universe Unfiltered
Celestial Fireworks
Presented by Dr. Frank Summers, Space Telescope Science Institute
To help commemorate Hubble's 25th anniversary in April 2015, our imaging team captured an amazing cluster of thousands of massive, hot, bright stars. The brilliance of the cluster inspired the metaphor of "celestial fireworks," celebrating decades of astronomical accomplishments. To make this beautiful image even more eye-popping, our visualization team processed it into a three-dimensional computer model and created a flight into the nebula. In this episode, Dr. Summers explores the spectacular image and reveals behind-the-scenes details of how the visualization was made.

Hubble Space Telescope Celebrates 25 Years of Unveiling the Universe

Show Notes:
-- It is remarkable that the Hubble Space Telescope reached the 25 year milestone. However, that doesn't mean the telescope is "old." The five servicing missions to the telescope provided a continuing series of advances in both the observatory hardware and the scientific instruments. In addition, two decades of experience running the observatory have brought about vast improvements in efficiency and yield. In so many ways, Hubble has increased its capabilities over the years and gotten demonstrably better with age. Scientific productivity is perhaps the best measure of the vitality of a telescope, and on that measure Hubble is a robust as it has ever been.
-- A search for the Spitzer Space Telescope image of the nebula Gum 29 finds an object known as RCW 49. They are the same nebula. There are multiple catalogs of nebulae by different astronomers, at different observatories, at different times. Colin Stanley Gum published his study of 84 nebulae in 1955, while the team of Rodgers, Campbell, and Whiteoak (RCW) produced a catalog of 182 objects in 1960. Other catalogs of nebulae include those of Caldwell and Sharpless. A nebula can be referenced by any of these catalog names, or by the more well-known NGC catalog number if such an entry exists. Unfortunately, there is no one standard naming convention, and cross-referencing between catalogs is a standard feature in astronomy.
-- In many of our visualizations, the stars were handled as image cutouts. If there are just a few hundred stars in an image, the process of identifying the pixels associated with each star is not overly cumbersome. Software written for astronomical research addresses such tasks and can be applied to visualization. However, dense star clusters with many thousands of stars present a severe challenge with tremendous overlap amongst the stars. The point-spread function technique, described in the video, is also an adaptation of research software. Although developed specifically for star clusters, the process can be applied to any image.
-- The development of computer graphics software to support Hollywood movies has greatly benefited our work in scientific visualizations. Astronomy is not a large enough market for specialized visualization software to be particularly profitable. Instead, we use the software written for the billion-dollar film market, and adapt it to our purposes. The sophisticated tools for look development, virtual cameras, and image rendering help add a cinematic feel, while we can keep track of the scientific details and ensure the presentation is astronomically appropriate. We strive for a combination of accuracy and aesthetics.

No matter how "old" these videos are, there're still wonderful and extremely educational! Thanks Hubble Institute 👍
How does this not have millions of views? This is amazing work. Thank you!

simple to answer really.....99.9 % of humans cannot or could care less to comprehend past the front of their nose... much less gasses that are expanding at about 8 and a half million(8,500,000) miles a day
big applause to the team who made this . love it
Even more beautiful is the passion of the presenter about the subject.

In true layman's terms
Really like these series of videos by Dr Frank Summers. He has a way of breaking down the data into layman's terms without patronising. Wish there were more.

Forest Ntt what happened to him?
That last sequence of moving through space that fast was mesmerising. Like the first time I used space engine. MIND BLOWN
What an era to live !!
Thanks a lot, Frank Summers. You are the best.
That's certainly a very hasty work!, and it one can imagine, this is just a mind blowing visualisation of nebulae. In spite of such a great work, don't know why people don't give it a like. (One can presume those who saw this presentation might not so exited about watching something, which they can never ever be able to watch without the help of the Hubble team).
It's been almost a year now, bring back Frank! We miss him. Great series.

Boofatcha what happened to him
Wow! That was a fantastic, "brief" interstellar journey that you've allowed me to go on just from the comfort of my couch. Thanks a lot!
I'd love to see more Hubble Unfiltered episodes in the future!
How fast did we travel in the animation? 10:47 I assume we start close to Sol 12:07 Journey ends about 13700 ly away. Journey last about 120 seconds. 13700 years ≈ 4.3x10^11 seconds So we travel at about 3.5x10^9 times the spead of light. Nice. I feel much younger.

I was actually wondering how fast the "camera" would have to move to see this, thanks fellow nerd lol
Great job! Thank you so much.
Amazing work!!!!!!!!!!!!! Thank you quadrillion times. Also, Frank Summers gives the best explanations on the subject.
These are the most interesting videos in youtube
Most Fantastic talk through by Frank Summers. I am already his fan. Thank you so much for the detailed explanations. You are a great teacher Just like Walter Lewins
Great shows of the night sky, great work.
Ive just saw today , january 10th , 2018, a shooting star here in the south hemisphere in the south direction , around 1:05 AM and I would like to share my experience with all you. Its amazing !!!
Absolutely amazing, thank you!
Amazing work. Thank you to everyone involved.
woooow brilliant!!!
Wow ! Thank you for this amazing work,
Fascinating
Amazing stuff
How has there not been a new unfiltered since 4 Years ago ? I want a new one ?
This video is awesome 👏
great work
Awesome
Thank you guys for making such impressive animations for us plebs aweing at the sky at night. Really appreciated. However I have a question: is you 3d "animation" up to scale, meaning are the distances between the star heavily condensed or not? Just wondering.
very nice.
New videos please please please.
I am 📙 to the next level
What software do you use to make the 3-D model? I am a graphic designer by trade, and I would love to learn how to do this. This would be my dream job to make visualizations like this. This is the most awesome thing I can think of for astronomy.
I don't understand what is he doing the entire video, until 10:41, Then I cried

Me too, felt like I was on a flight into heaven itself
Amazing how stars appear like a cross
view this channel is a very nice one
Wow
What software is used for the 3d modeling?
No more videos? Why not, please make more. Explain how you learn all of that stuff. My friend believes in flat earth because he cant understand how would you know all things what you presents
How can I get the image? then use it in one of those virtual walkthrough programs, so i can zoom in, out and around at will. That would make the Hubble's team work a fantastic teaching opportunity that i and many can use, also great for entertainment on any personal computer.

teabadge what?
How fast would we be speeding through space during the ‘Grand Finale?’
Wouldn't it be amazing to live in such a star custer? You would have Starswith a magnitude of -5 or -6 at the night sky, and of course, this amzing nebula:D
Cosmos, is all that ever was, is and ever will be! (Who said that? ;- ) )
you don't use a watch on your wrist Dr Summers, interesting, you don't need to know the time when traveling in space...
There seems more positive about celestial fire🔥work round the clock in our Universe . Is it a God particles....?.
son..
I hate those defraction spikes
I saw like a figure of a woman in the clouds (right). Who else?
So your photos are fake?
Can forward to 10:10. I just saved you 10 minutes.
