Hello and welcome! My name is Anton and in this video, we will talk about an extraordinary satellite of the Milky Way that currently makes no sense

Can we just take a minute to appreciate the work ethics of Anton? He can take research papers 10's or 100's of pages long full of science language, and turns them into a 10-15 minute videos that can be easily understood by someone with a reasonable intelligence. And we can't forget the friendly smile at the end. I say, good work sir!

Hello wonderful Anton. Thank you for the years of dedicated reporting you've done for the world. You spread goodness and it makes my days a little brighter when I get to learn from one of your videos. Thank you so much.

It's pretty clear that these stars are just staying together for the sake of the children. Once the kids are off to college, they'll all go their separate ways.

Anton is a true gift to humanity. I love you Anton you are just amazing and I can’t explain how grateful I am that you are doing this work. These are things that people need to know! Thank you for doing such an amazing job over the years Anton, you are such a wonderfully marvelous person ❤

[glennalderton]

What I would like to know, is how the night sky would look from the perspective of a planet in one of the satellite galaxies. The Milky Way must look fantastic!

I wish I was still actively partaking in hallucinogenics. Those universe simulations are trippy enough sober...
Stay Wonderful, Anton!

Yet another interesting co-mover group that can be, at least substantially, credited to our wonderful little satellite. "[W]e confirm the reality of Ursa Major III/UNIONS 1 with Keck II/DEIMOS follow-up spectroscopy and identify 11 radial velocity members, eight of which have full astrometric data from Gaia and are co-moving based on their proper motions."

[TheSwamper]

Every time the explanation is dark matter, I roll my eyes and think "OK, they don't know." Dark matter has not been proven to exist. They might as well just call it magic, but it'd be more honest if they just said "We don't know."

[rolestream]

I just want to say you work really, really hard and we appreciate it! =) <3

[Whittz.Youtube]

Here's a sci-fi movie idea. Like we have satellites around the earth, a species that's monitoring the galaxy created a mini cluster as a jumping point/satellite.

[stevenkarnisky]

Great mystery. Cannot wait to see the resolution!
Thanks for the dose of excitement, Anton!

[cryptc]

If that object has a lot of dark matter, wouldn't it cause major gravitational lensing, proving that it has dark matter?

[craigo]

Thanks so much Anton for showing us this study and explaining it's findings so clearly. It's really fascinating, a collection of 20 or so stars, travelling together at the same speed and staying together for 10 billion years despite the effects of huge tidal forces over this incredibly long period of time. What could possibly be 'holding' it together for so long?

[steveowens]

A collection of sixty or so stars, 10 light years across, with lots of planets, 10 billion years old, that should have fallen apart due to tidal forces but hasn't? Forget Omuamua. This is my idea of a starship!

[antibrevity]

3:39. That moving, white starfield murdered the video compression, turning Anton into a potato until it was over ;). Thanks for the video about this surprising object.

[OG_stevedidWHAT]

Thank you for the continued content and discussion

[jamesbarry]

Wow, thanks for letting us know all these fabulous

[epiccurious]

3 questions: Is it rotating around a gravitational center? And is there possibly a quiescent black hole at the center of it holding it together? Is it possibly a new arrival to the Milky Way that hasn't had time to be disrupted by the MW's gravitation?

[willsherman]

We enjoy your work so very much. Our window into the complex world of modern science. Thank you. We appreciate you.

[diGritz]

Imagine what will happen if one of the theories that explains away dark matter
turns out to be right. It becomes ridiculous when you consider how many of our
observations use something we don't know whether or not it actually exists.
