This is the result of a 20-year collaboration of several hundred scientists from around 30 different institutions worldwide.
The half-exploded star is careening across the Milky Way at 900,000 kilometres per hour, according to a new study by international researchers.
Where did the elements that make up our bodies come from? How fast is the universe accelerating? A pair of dead stars, among the weirdest scientists have seen, could point toward the answers.
In the latest datapoint supporting the radical idea that the universe isn’t totally random, a scientist’s observations of about 200,000 galaxies suggest a “rather exotic” model of a spinning universe that is losing its structure over time.
Two unrelated studies recently raised the same possibility: the laws of physics might not apply everywhere, which, if true, would upend an idea underpinning centuries of science.
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.
Beyond the impenetrable cosmological horizon is the unobservable universe: vast, possibly infinite, and maybe the likeliest location for alien life.
The record-smashing explosion in the cosmos was at least twice as bright as the next most luminous supernova ever observed.
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.
The blazar—powered by an extremely bright black hole that can blast a hole through galaxies—is the most ancient ever discovered, sending radio signals from the early universe
A spontaneous hole in the fabric of reality could theoretically end the universe, but don't worry: physicists are studying the idea for what it can teach us about the cosmos.
A supermassive black hole's eruption blasted for hundreds of millions of years, making it the biggest explosion ever detected since the Big Bang.
