When we think of the Big Bang, we think loud, hot, and bright. But was it followed by a colder, darker shadow? Read...

Behold the limitless, crowded cosmos. The Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Survey has put out its latest data release, increasing the size of the largest 2D sky map. Read...
Researchers used data from the Dark Energy Survey and the South Pole Telescope to re-calculate the total amount and distribution of matter in the universe. They found that there’s about six times as much dark matter in the universe as there is regular matter, a finding consistent with previous...
It may be tempting to load up on online shopping deals this Black Friday—but before you order a whole new wardrobe or electronics setup, take a moment to think about the trip all those packages may take. International shipping to bring all that stuff to your door is responsible for almost 3% of...
Astrophysicists Just Made a New Count of All the Dark Matter and Dark Energy in the Universe

A new analysis of more than 1,500 supernovae has put fresh precision on measurements of the dark matter and dark energy that permeate our universe. Read...
Despite being an excellent source of renewable energy, wind turbines, like most manufactured products, eventually need to be disposed of, for one reason or another. That poses an obviously large problem given their size, but researchers at Michigan State University are working on a novel solution:...
There is a realm the laws of physics forbid us from accessing, below the resolving power of our most powerful microscopes and beyond the reach of our most sensitive telescopes. There’s no telling what might exist there—perhaps entire universes. Read...
Despite the vast and expensive effort to figure out the identity of the invisible stuff that seems to make up much of the universe, no proposed dark matter candidate has been detected by any scientific experiment. Now, a team of researchers has suggested a design for a new dark matter experiment,...
For a little more than a week in July 2018, a team of physicists at CERN tried a new technique to slow down antimatter particles zipping around at breakneck speeds. Those 10 days of observation were the culmination of 10 years of development in an international collaboration called ALPHA, which...
One of NASA’s more important science missions now has a ride. The agency has awarded SpaceX a contract to launch its SPHEREx astrophysics project. The mission won’t blast off using a Falcon 9 rocket until June 2024 at the earliest, but it promises...
On the night of November 23, 2014, a powerful telescope on Mauna Kea in Hawaii was trying to pick out the enigmatic movements of a black hole traveling through space. In the seven hours the telescope peered at the cosmos, it may have caught one, as a structure about the size of Earth eclipsed a...
High up in Chile’s Atacama Desert, miles away from the dull glow of light pollution, the secluded Atacama Cosmology Telescope is in prime position to search the sky for answers. The question most recently on its mind? The age of the universe, a cosmic quandary that can be answered in different...
