Strange Objects Found at The Galactic Centre Are Like Nothing Else in The Milky Way

Posted by in category: cosmology

There’s something really weird in the centre of the Milky Way.

The vicinity of a supermassive black hole is a pretty weird place to start with, but astronomers have found six objects orbiting Sagittarius A that are unlike anything in the galaxy. They are so peculiar that they have been assigned a brand-new class — what astronomers are calling G objects.

The original two objects — named G1 and G2 — first caught the eye of astronomers nearly two decades ago, with their orbits and odd natures gradually pieced together over subsequent years. They seemed to be giant gas clouds 100 astronomical units across, stretching out longer when they got close to the black hole, with gas and dust emission spectra.
