stux⚡️Stars orbiting Sagittarius A* (Super Massive Blackhole in center of Milky Way)
Jo - pièce de résistance@stux wow.
What is that sparking thing in top left corner? With so much energy.
This is an incredible Timelapse.
Woozle Hypertwin@JoBlakely Looks like it's another star -- it comes into view at one point. The sparkling looks to me like the equivalent of lens-flare.
It'd be nice if the timeline weren't chopped up into multiple pieces; I wonder where the source material is...
I spent too much time on this, as I am wont to do: removed the duplicate bits, zoomed in on the timestamped bits (there didn't seem to be a lot of correlation between the lower and upper frames, so this zooms in on the lower frame, with the timestamps) and put the two separated segments together.
@stux I've been wondering when we'd have enough images accumulated over enough time to make a time-lapse of some celestial object, but I was thinking maybe a nebula or something; "black hole" was not on my list of likely candidates!
Sir Osis of Liver 🇨🇦 🇲🇽II can't hear the term 'super massive black hole' without also hearing this opening riff.

I should get help.

@Sir_Osis_of_Liver Heavy rock? 
Muse is cool

Helge WurstOne of the best time-lapses. Haven't read the paper yet, but here's the dark matter angle:
A Dense Clump Of Dark Matter, Not A Supermassive Black Hole, Could Reside In The Milky Way's Center.
There's been widespread agreement that a supermassive black hole resides in the Milky Way's Center. But that may not be true. Researchers say that a dense clump of fermionic dark matter can also explain the motions of stars and gas clouds in the region. Crucially, it can also explain the famous Event Horizon Telescope image of the SMBH.
GradientDescent@stux I don't like linking to YouTube, but David Butler has an excellent segment on sag A*.

Marcos Dione@stux what's that star going by in the upper left corner?
mossman@stux wow - that looks *EXACTLY* like the effect of a black hole in a space missile shooter game I played on an HP terminal in the late 1970s or early 1980s. Loved that game... Have looked for it on the internet several times but no luck.

@fluidlogic @stux no, that's more like Asteroids. The one I'm thinking of was like a space version of the game where you shoot at each other across a mountain range or city scape... You take turns to give angle and velocity and release your missile. In the space version you have to go around planets with their own gravity effects, so it's all about the orbital mechanics. Sometimes you would discover a blank point on the screen where weird slingshot effects happened like in the video up thread...
This was on an HP 150 touchscreen terminal from 1983 if I'm not mistaken.
Benben@stux I somehow had to pause for one second to merge two conflicting readings:I was in this namespace
John Harden@stux 😮 So this is 1999-2012, 13 years elapsed time?
