In the starless void of intergalactic space, there are clouds of cosmic gas as old as the Milky Way. They produce no visible light, and they barely radiate heat. Now, for the first time, astronomers have determined their size. These shadowy structures are as big as galaxies.
A controversial experiment at Fermilab designed to hunt for signs that our universe may really be a hologram has failed to find the evidence it was seeking, the laboratory has announced.
Billions of years from now, the universe as we know it will cease to exist. The good news is, that gives us a lot of time to prepare, and maybe even figure out a way to cheat cosmic death. Here are some possible ways our descendants might survive a cosmological apocalypse.
The nuclear strong force binds the smallest bits of matter together to form atoms, thereby making our material world possible. Physicists at Brookhaven National Laboratory have made the first-ever measurement of a similar strong force for antimatter — the mirror image of regular matter that lies at the heart of one of…
Perhaps you saw the news this week about new evidence that we do, indeed, live in a multiverse. A scientist claims he’s found signs in the cosmic microwave background radiation — the afterglow, so to speak, from the Big Bang — that our universe collided with another universe early in our cosmic history.
You’ve heard it before: In space, no one can hear you scream. That’s because sound doesn’t move through a vacuum, and everyone knows that space is a vacuum. The thing is, that’s not completely true.
Have you ever wanted to meander between two spiral galaxies, or follow in the footsteps of a comet? Now visitors to southwest Scotland’s Nith Valley can do just that. Welcome to the “Crawick Multiverse,” a massive installation created by renowned landscape architect Charles Jencks that gives symbolic physical form to…
Astrophysicists at Caltech say they’ve detected the oldest, most distant galaxy known so far. It’s 13.2 billion years old — just over half a billion years younger than the universe itself — and the discovery may change what astrophysicists know about the early history of the universe.
Brace yourselves: winter is coming. And by winter I mean the slow heat-death of the Universe, and by brace yourselves I mean don’t get terribly concerned because the process will take a very, very, very long time. (But still, it’s coming.)
A multi-decade analysis of a distant pulsar is affirming the longstanding notion that the gravitational constant—one of four fundamental forces of nature—is the same everywhere in the universe.
Calculations made by a JPL-California research scientist suggest that thin strands of dark matter filaments are spreading out from large planetary bodies like Earth and Jupiter. If true, it’s a possible sign that we may be able to finally detect these hypothetical forms of matter.
“Space is big,” said Douglas Adams. “You just won’t believe how vastly, hugely, mind-boggingly big it is.” But why must this be so? And why does our Universe exhibit such tremendous scale, from the very tiny to the extremely large? Here are some possible answers.
An exceptionally bright supernova discovered last month appears to shine brighter than 500 billion Suns. That’s twice as luminous as the previous record—but because it’s low in hydrogen, scientists are confused as to where this exploding star got all its energy.
Scientists working with the Planck Satellite have produced a new polarization map of the Milky Way in microwaves, providing an unprecedented view of a rather dramatic electromagnetic loop discovered over a half-century ago.
New research from Western University in Ontario suggests the universe’s first stars amassed in conglomerations so bright they shone with the power of a hundred million suns.
By applying the rules of Einsteinian general relativity to data pulled in by the Pan-STARRS telescope, scientist have developed two distinct simulations of supermassive black hole mergers that are considered the best yet.
Could there be a mirror universe, where everything is backwards – and everybody has goatees? How badly do you need to bend the laws of physics to make this happen?
Nothing lasts forever, not even black holes. According to Stephen Hawking, black holes will evaporate over vast periods of time. But how, exactly, does this happen?
Katie Silver has penned an article for BBC Earth in which she explores the idea of finding a single theory that describes the entire Universe. But as her article aptly points out, it's a challenge that appears to be getting increasingly difficult.
Information can escape the clutches of a black hole, say researchers from Buffalo University. And incredibly, they say this information is not just gobbledygook — it can actually be deciphered to show what lies beneath.
