In case you didn't know, a huge -- like, on a galactic scale -- cloud of gas is currently speeding toward our galaxy at 700,000 mph.
Galaxies are known to contain stars, planets gas and dust, but one particular nearby dwarf galaxy is notable for lacking the latter -- it's astonishingly dust-free.
This massive black hole candidate may be of the 'intermediate-mass' variety, possibly tying up a perplexing astrophysical puzzle.
Scientists have made a cosmic growth chart of the Milky Way galaxy, an innovative blending of data collected by the ongoing Sloan Digital Sky Survey and a new technique to determine the ages of stars.
Although a mysterious cloud of gas was supposed to get eaten by the supermassive black hole at the center of our galaxy, its survival has revealed some interesting features surrounding the gravitational behemoth.
The winter sky is by far the best time for astronomy. Long, dark nights with cool weather can present us with fabulously clear dark skies that last for hours -- let's hunt down some astronomical treasures!
How low can you go? Astronomers have found a star with an incredibly low concentration of heavy elements that still has a sizable planet around it — the most metal-poor star ever discovered with an orbiting, rocky planet.
There's some hot stuff on the edge of our galaxy.
