Last week, a group of astronomers announced that they had for the first time discovered the source galaxy for a mysterious type of event known as a fast radio burst (FRB). But only a few days later, another group of scientists produced informal research that suggested otherwise.
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.
A supermassive black hole at the center of a neighbor galaxy apparently 'burped' after swallowing up nearby matter, a phenomenon that may have been instrumental in shaping the early universe
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.
The find affords researchers a rare look into how ancient galaxies evolved.
To celebrate 100 years since Einstein formulated his theory of general relativity, we celebrate the beautiful observations created by a spacetime phenomenon known as gravitational lensing.
Astronomers have detected something baffling at the furthest frontiers of our observable universe: lots of massive galaxies that shouldn't even exist.
In a galaxy, 600 million light-years away, a black hole deathmatch is ripping up spacetime, exposing some fascinating dynamics at the heart of a powerful quasar.
