Using NASA's James Webb Space Telescope, Northwestern astrophysicists gained the longest, most detailed glimpse yet of the supermassive black hole at the center of the Milky Way.

The supermassive black hole at the center of the Milky Way appears to be having a party—and it is weird, wild and wonderful.

The Hubble Space Telescope has captured this striking image of an unusual galaxy with a bullseye structure, as nine rings surround its central point. Technically known as LEDA 1313424, the galaxy has ...

Hubble’s high-resolution imagery allowed researchers to hone in on more of the Bullseye galaxy’s rings — and helped confirm ...

the Andromeda Galaxy will collide with the Milky Way, resulting in a spectacular cosmic collision! Don’t worry, though – the distances between stars are vast, so we won’t feel a thing.

Explore the James Webb Space Telescope's incredible discovery: a cosmic alignment revealing the teenage years of our Milky ...

It seemed that these redshifted galaxies were all moving away from the Milky Way. Hubble’s results suggested the farther away a galaxy was, the faster it was moving away from Earth. Hubble got ...

The astronomical panorama is a major accomplishment because Andromeda is the “closest” large galaxy to ours, at a distance of 2.5 million light years away — equal to the diameter of the Milky Way disk ...

Observations show Andromeda has a more active star formation history than the Milky Way, potentially due to a past galactic collision. NASA recently released images of the Andromeda galaxy ...
