A speculative “corona' may be responsible for the odd properties of the Magellanic Stream, a river of gas and galaxy guts that stretches across half the night sky.
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.
The Milky Way tore apart a collection of extremely old stars two billion years ago, and scientists have found the grizzly remains.
An international team of scientists has discovered a filament of a fundamental structure known as the cosmic web hiding in the 'Zone of Avoidance,' and it's one of the biggest structures ever seen by humans.
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.
For the first time, scientists have detected clear patterns in a group of humongous and noisy stars that could unlock secrets about how our galaxy formed.
In yet another win for Albert Einstein’s theories, scientists report the first ever detection of “Schwarzschild precession” around a black hole.
For years, scientists debated whether the glow was a telltale sign of dark matter. A new study refutes that theory, but that only deepens the mystery.
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.
When the supermassive black hole at the center of our galaxy explodes, it likely eviscerates any life close to it. But over longer distances, these bursts of radiation may help life emerge.
