2022 and it's still chugging along.

2023 and hubble is still going strong! As an american proud of this, our greatest contribution to all mankind, I'm so glad. My earliest memories of astronomy are images from hubble and I'm so glad it's still up there giving us data!

I had the pleasure and honor of performing (as a juggler) at the 50th birthday party of a Hubble engineer during the period between the original launch and the service mission which fixed it. (I threw in some jokes about redshifted juggling balls, which went over quite well). Most memorable, though, was when the attendees, rather than Pin the Tail on the Donkey, played Pin the Corrective Lens on the Hubble. Clearly their sense of gallows humor was well developed by that point.

Her voice over and story telling made this an epic, yet a sad video.

My dad and his friends worked on Hubble a Lockheed. They were very proud of that program. I later worked at Lockheed as well. On Hubble's 20th anniversary I attended a celebration event that included 2 of the astronauts from the mission that launched the telescope. I met Kathy Sullivan and Bruce McCandless. They were the EVA crew that was to be prepared to do a spacewalk should it be required. It was an amazing spacecraft and an amazing era.

Sullivan also flew on the first servicing mission, STS-61.

I especially enjoyed the shot of the astronomers reaction when they received the first good quality images. I always enjoy those "Happy Nerd" shots in any endeavor like this.

As I recal, they DID test the mirror on the ground, but the error on the mirror wasn't in the grinding, it was in the design itself. Which was also used to create the test equipment. So, the test equipment showed "AOK", but since the design of the test equipment was flawed, those results were a false positive...

You got to see the looks of NASA people when they corrected Hubble's "vision"; priceless moment of joy!

hubble is by far my favorite telescope ever

I started studying astronomy in 1992. I remember the disappointment of Hubble being ground the wrong way, and the relief (and awe of its first images) when the corrective optics had been installed.

I love videos with her! Thanks Brady!

I love having information fed to me through videos. It's alot easier than reading wikipedia entries. Keep it up Brady.

All upgraded instruments installed during HST servicing missions have taken the curvature of the mirror into account. so the corrective optics the astronauts installed was no longer needed by 2002. That module, called COSTAR, was brought back by the last servicing mission in 2009 to make room for the Cosmic Origins Spectrograph. You can go see it at the National Air and Space Museum.

What a very well-done video.

I saw the IMAX movie about Hubble at the Science Museum in London, it was one of the most intense experiences ever. Unlike some of the other "3D" space films, this one was shot on IMAX cameras and it was as close as one gets to actually being there. Highly recommended.

I sincerely hope they find a way to preserve hubble. Either keep it in orbit or somehow get it back down to the ground and put in a museum. Because that telescope is too precious. In sentimentality.

MetalMonarchy what are you suggesting ? "Hey NASA, please attach a bunch of parachutes on the telescope and bring it back to earth !"

How you get time on various telescopes was mentioned in some other video. You need to submit a proposal and a committee decides whether to grant you that time or not. In some ground telescopes, once your proposal got accepted, you actually go to the telescopes and do the observing; in others (and I assume in case of Hubble), it is done automatically which has a benefit that if the conditions are not good for your observation, some other may be done, and your done later.

She's Canadian. She got her BSc in New Brunswick. I think the most remarkable thing about her speech is that she often pronounces her t's as t's when most North American English speakers would pronounce them as d's. E.g.: 3:32 "So a few years later..." instead of "...lader..." I don't know if it's a shibboleth of her accent or her just speaking clearly for the video. She is very clear, though, and I enjoy listening to her explain things even if I already know them. :)

What an excellent video. Great narration and a very good choice of images to go along with it.

Didn't know that. Thanks for the update.

Wonderful! What a work of art too! Sending best wishes to you from this side! :)

Gotta love the Hubble.

Hubble introduced many of us to the beauty of the cosmos , it will be like losing an old friend. The simply mind blowing new GMT, Euclid telescope and others will see everything you could ask Hubble to aim at, repeatedly and in grater resolution as a matter of coarse. That has to be one of the most astonishing facts in human history. D S V. 👋👍

As the matter of fact, Hubble was designed for a very large spectrum from 0.115-1.03 μm of the STIS to 0.2-1.7 μm of the ACS, near-infrared spectrum was possible before the NICMOS when offline.

Brilliant video, one of your best Brady :).

I am too young to "remember" Hubble's day one flaws but I knew about them before this video but still nice. Thank you Brady keep more videos coming. :->

STILL STRIVING!! GO HUBBLE!!

2017 and still goin good

We can... in fact I believe Dr Gray has spent time on the selection panel (one of the jobs of many astronomers is to pend tie on these panels, sifting through proposals). See our earlier video with Dr G in which she is writing one of these submissions!

I still remember when one of the lenses built to correct Hubble's vision passed through Pittsburgh on its way to Florida. That was a crazy convoy to watch

I found this strangely moving. Beautiful video.

Can't wait. I hope by then I can receive some observation time on it. Its practically impossible to receive time on the Hubble now a days.

During polishing, the device which determined the contour of the mirror wasn't calibrated correctly, saying it was correct when it wasn't. It's one of those things that no amount of on-Earth testing could have spotted, since the telescope relied on being in orbit to function as expected, so they had to take the instrument's word for it. Once they saw it wasn't right, they used data from the onboard null corrector to figure out how bad it was off.

Beautiful ... :)

I can't frikken wait for the James Webb Space Telescope.

Thank you!

Great Video. You should do a video on pulsars.

Dearest Dr. Gray: Please, please, please try and find time to do a video on ARP 273 and explain some of it's incredible features and neighbors!! Not to mention: So many RED objects, so little time...! Humbly thanking you, Kit

although it was indeed disappointing when it failed to work at first deployment, the fact that we successfully serviced the Hubble makes it a little more special, and its images more satisfying, because of the engineering involved in those subsequant missions--not to mention its longevity. Let's just hope James Webb works on the first and only try it'll get!

Thanks, very interesting!

So it was inaccurate with a very high degree of precision!

Presents people make themselves are the best :-) Very cool.

I can't believe I just subscribed to this channel. Wait...yes I can.

I had to go back and watch the reactions of the scientists to the, probably, first picture which indicated that they had fixed the problem. I wonder how different the world would have been today if that mission had failed. For all I know, it could have had a significant impact on subsequent space telescopes and NASA funding etc. I'm glad it worked :) Also, I'm happy that this video was uploaded as I just watched an hour long presentation of the JWST. Should make a good video Brady :)

The editing of this video is really good indeed. So much different footage - I love it. I wish you could do magic and release so much more, because I really like your style of videos. Much of the "sciency" series on TV are just not smart enough - they dumb it down way more than needed. You also focus on the layman, but in a way to educate them.

Wow only 6'' high bumps. This is astonishing!

Interestingly, one of the jobs on the last mission was to remove the correcting mirror array (COSTAR) and replace it with an instrument (Cosmic Origins Spectrograph). In the servicing missions, all the original instruments had been replaced, and the new replacements all had corrective optics, rendering COSTAR unnecessary.

Dr Gray's CV says that she has had actual eyepiece time with Hubble in 2004. Sooo jelly!!

Aww, I was hoping for a video on the Witches Head Nebula (or some other Halloween themed object) never the less, Hubble is still awesome :D

I like Meghan. I could listen to her talk for hours.

Well fortunately in 2020 hubble is still going strong. We have been trying to launch JWST for some time now, hopefully they'll get it up there in 2021? I'm gonna come back and rant here if they don't by then!!

She is really good at pronouncing those T's!

lol yea me too, i was so happy to see mission control's reactions when curiosity landed. scientists aren't known to be the happiest/expressive types of people so when they are, you know that it must have been something profound that happened.

I love this woman!

I remember reading an article in a magazine in '84 or '85 about how they made that mirror and how they fixed a small crack that had developed in the mirror by drilling it out. One part of the article was about how precise they needed to be in their measurements and if they got it wrong it would be a disaster. Years later when they announced the mirror flaw, I remembered that article. It was that article and help from my grandfather which lead to me getting into science and aerospace.

The tech on the ground - adaptive optics and suchlike - has reduced the need for a space telescope in the visual. We can cancel out the atmospheric interference to get images that rival or even surpass what Hubble can do. What we do need in space is telescopes that sense wavelengths that get absorbed by the atmosphere. Despite all this, webb will produce enough pretty pictures to pay for itself many times over.

When I first read this comment, I was thinking: HEY WE PRONOUNCE IT AS T. Then I said the sentence out loud and realized you are right. Its just a bit easier to pronounce it as a d. Although we don't do it for all words, like it for example. I guess it just depends on what letters come after it.

NEW DEEP SKY VIDEOS AAAAAAAA

It'll be a sad day when its shut down but there is JWST to look forward to.

very interesting, i did not know that it was a failure for the first few years ^^

I'm curious to know how an astronomer gets working time on the Hubble. I assume there's an administrative process to apply for a turn to take the pictures one wants? Maybe you could do a video on that involving Dr. Gray.

What type of orbital telescope will substitute Hubble when its time for retiring is due? Thanks.

I'd love to know exactly how the Hubble mirror got polished wrong and testing missed it, and how did they figure out how to fix it. Was it designed to allow for a correcting lens or lenses?

Are you planning on doing something on the James Webb space telescope?

"how the Hubble mirror got polished wrong and testing missed it" The testing instruments were badly calibrated and due to time pressure, the mistake went unnoticed through several steps of independent testing. In essence, it was a string of human errors. "Was it designed to allow for a correcting lens or lenses?" No, they had to remove one instrument (the High Speed Photometer) to put the correcting lenses in the optical path. See the wikipedia entry on Hubble, it has all the details.

someone tell me why I seen video and on the internet I cant find a hook up to watch it

I agree wholeheartedly, but it probably will not happen. There once were plans to bring hubble back down with one of the last space shuttle missions. Space shuttle was the only spacecraft designed to not only launch satellites but bring them back down as well. However, after the Columbia accident the risks were deemed too great. If an empty shuttle can burn up in the atmosphere, the risks of it burning up while carrying 20 tons of cargo are much greater.

Probably, but a cool one!

9 years ago "shut down in the next couple of years"... Fingers crossed... Maybe we'll actually be able to fix it again at some point

Wo! Send along some congratulations to the new Doctor would you? Once he recovers from the defense, I've heard those things can virtually vivisect the mind.

I remember hearing that they were working on software which would clarify the vision from the atmosphere. ( on land based telescopes ) To be able to get images even clearer than Hubble. Was I dreaming?

When is the james webb telescope coming?

Every time I see Dr. Gray's wedding ring I die a little inside.

So I know Hubble will be decommissioned soon and we got the Chandra, Webb (in a few years) etc , which shoot in different wavelengths though. My question is the following: is the Webb telescope going to be a worthy replacement of Hubble in the visible spectrum or we just dont care about that anymore?

Are there any plans for a better replacement?

They should GET ON WITH IT AND GET IT UP THERE!!! :-)

in few years not only the clouds will affect the ground based telescopes, but also space debris.

there need to be a biology channel along with numberphile, psyfile, periodicvideos and deepskyvideos

the James webb telescope is one off the replacement for Hubble, I think the have plans for more than only that one

yep, the james webb space telescope... And it's MASSIVE

yes.

Happy scientists make me happy :3

In terms of its data and how its images connected with so many people, the HST is possibly the greatest single collection of 20th century technology lofted into space. It will certainly be a significant historical artifact. Simply deorbiting it is a major anthropological loss. I'd like to see a joint NASA/ESA/SpaceX/etc venture to retrieve it. The 26k people who signed the Death Star petition should already be campaigning for this. I'm not down with the DS but I'd be happy to save the HST.

I'm wondering if James Webb telescope will start in the same way as hubble.

Are you saying that they will let it in space or destroy it?

24th April 1990 is my birthday too and I love astronomy, coincidence? :)

Will it be replaced soon?

RIP Hubble Space Telescope

What area of North America? Like England, America just has one accent to foreigners, but if you live here, there are several: east coast, west coast, mid west, New York, southern, and the different accents of Canada. She sounded Canadian to me

4:00, nerd equivalent of the super bowl lol (I would love to be there myself)

So how about the James Webb Space Telescope?

At the end, Hubble should be brought down to Earth and placed safely in a spot where it can rest for the eternity.

Brady, you should do a video asking Dr. Gray what she thinks about being the crush of the internets

yes, the james webb

VLT with adaptive optics can produce images more sharp than HST.
