Great video! Thanks for highlighting our works. Just share one more thing about FGS part, it’s not only due the exposure duration. Actually we were using different tracking mode during the commissioning but also pointing towards a field which has more reference stars. ESA and our EC scientists have put a lot of effort on it, the good news is that in the end we managed to solve the issue🎉
Missed, but not forgotten. Yes, please, to your offer on your Planetarium. You always put on a good production. I'm sure that would be just as interesting as your other installments. Thanks.
Christian, each of your videos is a golden nugget! You go down to minute details I'd hardly ever find by myself. I still remember your η Car video with those simulations of spiraling gas shells and explaining the protrusions at the “waist” of the nebula-wow! It's fair to say that every video makes me say “wow” not once!
@@LaunchPadAstronomy And when I think of Euclid, Gaia and the upcoming N. G. Roman telescopes, I feel a paradigm shift in astronomy. Thanks in part to the proliferation of useless cryptomining and chatbots talking like they lost a few marbles, we have such a huge and still growing, and more and more affordable computing infrastructure. Last year I set my personal record: I ran a computational experiment in parallel on 180 32-core machines in the cloud. I'm now getting results in a couple hours from computations that 10 years ago would take 10 years to complete on what I had back then. :) Astronomy is shifting towards being a Big Data science. The amount of data in these wide-field observations is so many orders of mag beyond what astronomers (their grads, actually, I remember my time as one :-)) ) and the Galaxy Zoo regulars can ever process by eyeballing.
Great video! I wish these ESA missions like Euclid and Gaia were more well known. They are so important to astronomy but most people don't even know of them.
We don't mind Days Between your videos Christian, they are so good they are worth the wait! Yeah tell us about the planetarium, I'm in blighty with no chance of getting there to see it.
Well thanks. Of course, I'm always trying to get things just exactly perfect, which I really have to ease up on. Happy to talk about the planetarium though!!
Fantastic video as always, Christian! Thank you for this; your videos are my favorite way to catch up on what's happening in space and astronomy! I'd love to see what kind of work you've been doing with the planetarium.
Christian, if you consider the topic interesting, could you talk about the superenergetic events MS 0735.6+7421 and NeVe 1? I searched for papers, but what I could find was too specialized for me (I have a degree in physics, good grasp on GR, but still, astrophysics at depth is a different beast), and Internet news and press releases are dumbing down everything. Wikipedia says the Oph cluster eruption was generated by the NeVe 1's SMBH consuming 270×10⁶ M☉ worth of material (it's an order of a dwarf galaxy mass!), but then Eddington limit? And I couldn't understand the significance of the 10 kly distance between the eruption center and the current position of that galaxy: Wikipedia says this ended the eruption depriving it of _gas,_ but I can't imagine accretion of 270×10⁶ M☉ of gas alone by the center of a truly giant elliptical-how would the gas sneak to the center in the first place? I naively imagine that it was really either a compact, dense, tightly gravitationally bound dwarf galaxy. If it was a gas cloud, then it would more likely disrupt orbits of the galaxy's own stars-but then, a single continuous eruption, even if 1My long, against the light and burped matter pressure of a feasting SMBH? How dense such a gas cloud should be to pull such a trick? Sounds implausible. If you'd ever consider as detailed an explanation as yours always are, I'd be happy!
Wow, that does sound interesting. I confess I'm not familiar with the astrophysics involved here either but I'd like to take a look at it. Who knows, maybe there's a video in there somewhere? :)
@@LaunchPadAstronomy They are called in popular articles and… ahem, ever reliable Wikipedia as the two known most energetic events in the Universe, both of the order of 10^54 J. I likely have to correct them, most energetic events in EM: LIGO and friends have probably seen higher energies, not even speaking of their power. Still, these are unimaginable energies, even if released over 10⁵-10⁶ years! There is a 2-min long video at the Chandra's site, but it's popular, for the public. I could find nothing even remotely close in the level of detail to your η Carinae nebula breakdown. All videos and articles explain how the remnant was discovered-the Oph supercluster eruption, how its called, multimodally in X-ray and radio-but not what probably happened.
Yeah, I found that surprising, myself. Goes to show that you can do your best to simulate space on Earth, but it's still a best guess until you go there.
Great video. Sad to see not many views. I didnt even get the new video appear on my feed. RUclips really prioritses accounts that post quantity over quality 🙄
It could, but Euclid might be an even better tool because of its wide field. Unfortunately, NH is in the constellation Sagittarius which isn't part of Euclid's survey space.
this is probably my gamer brain talking but this explanation makes me imagine Hubble and Webb with these slick high powered sniper rifles (feel free to visualise Hubble as a grizzled retiree) and Euclid rocks up like sup I have the world's most advanced bazooka lol
Can you give us an update on all the new telescopes that Covid almost killed but are still in the loop? Please? ELT someone? Rubin, Roman, Magellan, TMT, SMT?

You're back 🎉
I hope you are ok and nothing bad kept you from creating astonishing videos
Thanks! Nothing bad happened, I just got overwhelmed with my day job :(
@@LaunchPadAstronomy that's very nice to hear. You're a gem Sir. Do not forget that ❤️
Great video! Thanks for highlighting our works. Just share one more thing about FGS part, it’s not only due the exposure duration. Actually we were using different tracking mode during the commissioning but also pointing towards a field which has more reference stars.

Thanks for the clarification, and congratulations on getting that issue resolved so nicely!
Missed, but not forgotten.
Yes, please, to your offer on your Planetarium.
You always put on a good production. I'm sure that would be just as interesting as your other installments.
Thanks.
I second that!
Great to see you again. I was wondering a few days ago. Yes, I'd love to see your Planetarium. Best of luck at Towson University.
It's always a great day when there is a new LPA video! Thanks Christian; I can't wait to watch it.
These videos are always a gift. Thanks for coming back!

A treat as always, good to have you back!
It’s good to have you back dude!
Oh WOW 🎉 HoverPen is so freaking cool!
Great video! I wish these ESA missions like Euclid and Gaia were more well known. They are so important to astronomy but most people don't even know of them.
15:35 - Yes! Planetariums are cool....
15:35: “video about the planetarium” - Yes, yes, please!
Welcome back! Thanks for The video!!
As usual, I love your videos. Keep posting so we can keep learning !
Thank you so much. I'm glad to be back making videos!
thanks for the new video!

I’ve missed you. Best videos on the subject.
Interesting and useful science content
Holy moly! The amount of information generated by Euclid will keep astronomers very busy for a long time. What a great investment!
Fantastic video as always, Christian! Thank you for this; your videos are my favorite way to catch up on what's happening in space and astronomy! I'd love to see what kind of work you've been doing with the planetarium.
Thank you so much, I really appreciate it. Will definitely put together a planetarium video!
Definitely would like to hear about the planetarium, and also just generally about your academic work
Christian, you made my day with this video! I always look forward to your videos!!
Thank you so much!
Welcome back Christian. And yes, we definitely would like to watch the planetarium video.
Thanks! And happy to do the planetarium video!
Nice to see you back!
Thanks, it's good to be back!
Amazing. I’m really wanting to get into deep sky astrophotography This is a huge motivation to get doing it.
New video! 🎉 More than 20 JWST updates needed to catch up 😊
Sorry I've been so absent!
excellent informative video. god bless
Thanks
Thank you so much!
Where have you been Christian?!?!
Yeah, sorry I've been so absent. I talked a little about it at the end of the video :)
I would love to see a video about the planetarium!
Love space and science
Do we know if most globular clusters harbour a black hole in their centres like galaxies do in theirs?
Yes please, post a video about your planetarium. :)
Yes, planetarium video please.

I think waiting 2 years for the data release will be manageable. It’s only been 13.7 billion years in the making 😊
That light streak seems like a really benign error. I wonder why it wasn't cought in the prototype testing.
Yeah, I found that surprising, myself. Goes to show that you can do your best to simulate space on Earth, but it's still a best guess until you go there.
Great video. Sad to see not many views. I didnt even get the new video appear on my feed. RUclips really prioritses accounts that post quantity over quality 🙄
Tell me about it.
Can the GWST be used to search out candidates for the New Horizons Probe to continue its mission of visiting Kuiper Belt objects?
It could, but Euclid might be an even better tool because of its wide field. Unfortunately, NH is in the constellation Sagittarius which isn't part of Euclid's survey space.
@@LaunchPadAstronomy Seems like the very thing Euclid avoids, our galaxy and more specifically it's center
Exactly. Also makes searching for KBOs that much harder since it's such a crowded part of the sky.
this is probably my gamer brain talking but this explanation makes me imagine Hubble and Webb with these slick high powered sniper rifles (feel free to visualise Hubble as a grizzled retiree) and Euclid rocks up like sup I have the world's most advanced bazooka lol
Can you give us an update on all the new telescopes that Covid almost killed but are still in the loop? Please? ELT someone? Rubin, Roman, Magellan, TMT, SMT?

We cant be the only ones floating on a space rock.
I would like to see a video about the planetarium! WHO’s with me?
