Look at those stars in the center.

 

[prvteye2003]

that's cool

That's pretty cool.

I remember one of my astronomy professors always told us that if a supernova were to become visible from the northern hemisphere, she would give the whole class an A for the semester. She wanted to see one badly during her lifetime.

Those stars be truckin'.
That's our galactic center, correct?

Yep.

Oh come on people! This post has been up for an entire half hour and nobody has posted a pic of an anus! This forum is losing it's touch :disgust:

 

[Schadenfroh]

sweet, those things are invisiable right? those stars behind it or infront of it or getting sucked into it?

 

[Viper GTS]

Stupid question, but why are some of the stars moving away from it?

[dighn]

are the stars orbiting around the blackhole?

that's what I was thinking...

I'm betting it's a combination of the angle of view, and the fact that they may be moving parallel to it...

Almost certainly just an eccentric orbit.

this is awesome but i dont get why the other stars dont move either (there are stars closer to the black hole that dont move at all - or at least there appear to be).

I have a feeling that the stars aren't necessarity moving, moveover their light is being bent. The angle between our planet, the blackhole, and the stars is changing, causing light passing near the blackhole to be bent at different angles, making it appear to use as if the stars are moving.

This accounts for the seemingly confusing motion of some of the stars (some moving opposite directions), as some stars are behind the black hole, some are on one side, some are on the other, etc. most likely the stars aren't being 'sucked in'.

Don't think so 2 dimensionally. Those other stars could be hundreds or thousands of lightyears away from the black hole. They just happen to be in the same field of view.

Most plausible explanation I think.

How fascinating for it to be if one day we made a craft to observe a black hole. If they even exist that is. Where light and time do not exist.

But whatever it is, they say it's over 21 million times the mass of our sun and sits like a rock in space . Even if its not a black hole it's pretty damn impressive.

I think that would have some trouble with taxpayers...

"We're going to build this ship to send into a point of infinite density where it will surely be ripped apart before being completely broken down on the subatomic level and all its matter will cease to exist as we know it. It'll cost 800 Billion and it will get there in 60,000 years. Questions?"

I thought it was going to be an all black pictures

Also a couple of those stars could have been slingshot by the blackhole and are headed away.

Anyone know of a solar system/gravity simulator that does 3 dimensions? I've see a few 2d ones around. It's neat to setup a solar system and have a large intruder(planet/sun/black hole) enter a solar system and rip it apart.

Lol. A fanciful thought in deed.

No, the stars are not being sucked in. If they were, they wouldn't disappear. To us, they would stop right at the event horizon (the point at which light can no longer escape).

It looks like the light is just being heavily distorted by the hole.
