Scientists See Trippy Quadrupled Black Hole While Peering Through a Galaxy
Using another galaxy as a telescope created a trippy quadrupling effect in a rare image of an exploding black hole from the early universe.
A Weird X-Ray Signal Is Coming From Nearby Galaxies and Nobody Knows Why
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.
We Actually Live Inside a Huge Bubble in Space, Physicist Proposes
What if the Earth, the galaxy, and all the galaxies near us were enclosed in a weirdly empty bubble? This scenario could resolve some longstanding questions about the nature of the universe.
Our Galaxy Is Mysteriously Distorting and Nobody Knows Why
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.
A Black Hole Spewed the Ingredients for Life Across the Galaxy, Study Suggests
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.
Scientists Have Detected the Biggest Explosion Ever in the Universe's History
A supermassive black hole's eruption blasted for hundreds of millions of years, making it the biggest explosion ever detected since the Big Bang.
Scientists Found Breathable Oxygen in Another Galaxy for the First Time
Molecular oxygen is a key component of the air humans breathe, and now astronomers have spotted it a half-billion light years away. But don't hold your breath for quasar whippets.
Strange Dark Matter Findings Could Rewrite the Universe's History
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.
Watch This Ultra-Hypnotic Supercomputer Simulation of Galaxies Feasting
The color-coded NASA visualization reveals the turbulent relationship between galaxies and the gassy “fog” that surrounds them.
There’s Growing Evidence That the Universe Is Connected by Giant Structures
Scientists are finding that galaxies can move with each other across huge distances, and against the predictions of basic cosmological models. The reason why could change everything we think we know about the universe.
Scientists Are Chasing an Ancient Signal That Could Explain the Modern Universe
The faint, 12-billion-year-old signal would lead scientists to the very first stars and illuminate the origins of the modern universe, dark matter, and, well, everything.
A Nearby Cannibal Galaxy Is Going to Eat the Milky Way, Scientists Say
If Earth still hosts life in four billion years, whatever exists will be treated to the most spectacular night skies in the planet's history.
