The discovery of the bridge is another tantalizing step towards observing the cosmic web: the vast network of dark matter and hydrogen gas believed to form the backbone of the universe.
12 billion light years from Earth, scientists spotted a galaxy that is the spitting image of a young Milky Way. Its discovery challenges our understanding of the early universe.
Two recent studies probed ripples in spacetime from cataclysmic black hole events to reveal light in an implausible place and a mystery object in the cosmos.
Astronomers are trying to figure out whether the star collapsed into a black hole without going supernova, or if it disappeared in a cloud of dust.
Scientists estimated how many alien societies in the Milky Way can send interstellar messages. But just because they can talk does not mean we will hear them.
A disk galaxy in the early universe, just 1.5 billion years after the Big Bang, somehow formed during a time of chaotic cosmic conditions.
New observations reveal that an “extraordinary” optical illusion on a massive scale is making a jet from the galaxy 3C 279 appear to move 20 times faster than the speed of light.
The Milky Way's edges are warping and distorting in strange ways. A new study suggests the latest possible answer: another galaxy is messing with us.
Scientists have discovered the first fast radio burst that beats at a steady rhythm, and the mysterious repeating signal is coming from the outskirts of another galaxy.
The odd, dusty objects at the center of our galaxy could be stars that have been unified by intense tidal forces.
The shadowy entities are about 10,000 to 100,000 times smaller than the dark matter halo of the Milky Way.
Scientists believe that mysterious dark matter is key to forming galaxies in the cosmos. Now, a recent series of bizarre findings threatens to undermine everything we think we know.
