NGC 5746 :: NGC 5746 Handout - Chandra X
... Caption: Chandra's observation of the hot halo (blue) surrounding the optical disk (white) of NGC 5746 should help astronomers better understand how galaxies form. Spiral galaxies are thought to form from enormous clouds of intergalactic gas that collapse to form spinning disks of stars and gas. The ...

... In the years leading up to 1920 Kapteyn completed a huge survey of stars to determine the structure of our galaxy. He did not know anything about the absorption of starlight by dust in the galaxy and decided that our galaxy, and therefore possibly the universe, was like a flat lens with a diameter o ...

... Setting vesc = c yields the Schwazschild radius of the object: Rs = 2GM / c2 If an object of mass M is compressed to the point that its radius R is less than its Schwarzschild radius Rs, then it would require a speed greater than the speed of light to escape its surface. Since nothing travels ...
