The hunt for the elusive dark matter received yet another blow earlier today at an international conference in Sheffield, England. Scientists with the Large Underground Xenon (LUX) dark matter experiment announced that they found no hints of dark matter particles in their latest analysis, despite increasing the…
For the second time this year, physicists at the Advanced Laser Interferometer Gravitational Waves Observatory (LIGO) are giddy with excitement. They’ve just confirmed the second detection of gravitational waves, ripples in the fabric of spacetime proposed by Albert Einstein a century ago. It seems we’ve officially…
Add this to the list of existential fears that keep you up at night: the universe appears to be expanding faster than we thought. A lot faster.
In need of a quick refresher course on, well, the science of pretty much everything? Here’s a cheeky, irreverent summation of the universe in just four minutes from Exub1a, YouTube purveyor of “spacey stuff and existential angst.”
On the grandest scale, our universe is a network of galaxies tied together by the force of gravity. Cosmic Web, a new effort led by cosmologists and designers at Northeastern’s Center for Complex Network Research, offers a roadmap toward understanding how all of those tremendous clusters of stars connect—and the…
Ten years ago, billions of humans had their worldview upended when a group of astronomers announced that the solar system only contains eight planets. Now, the same guys are trying to rewrite our childhood mnemonics once again. A ninth planet may exist after all, and it isn’t Pluto.
For years, astronomers have puzzled over “fast radio bursts” (FRBs), mysterious cosmic beats that may come from pulsars. Now, for the first time, researchers have pinpointed the location of one such burst—and the discovery hints at an even more epic origin story.
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.
