In the very first moments of the universe, matter didn’t exist as we know today. A millionth of a second or so after the big bang, the universe was a dense, hot soup scientists call quark-gluon plasma (QGP). For several years, particle colliders—which smash molecules together at nearly the speed of light—have been able to
From this vantage point, Roman will conduct an unprecedented survey of the universe. Its field of view is 100 times larger than Hubble’s and, according to NASA, it can survey the sky 1,000 times faster using its 300-megapixel infrared camera. Roman also has a Coronagraph system that can block and mask glare from stars, allowing
Pandora, NASA’s newest exoplanet mission and the first satellite to launch through the agency’s Astrophysics Pioneers program, is now making unique observations of worlds beyond our solar system and the stars they orbit. The mission will determine the atmospheric make-up of at least 20 exoplanets, including the presence of hazes, clouds, and water. “Pandora’s data

Los Lunas, New Mexico A company has started to build a fusion machine that it hopes will be the first to generate more energy than it consumes, thanks to the use of immense pulses of electricity to squeeze capsules of hydrogen fuel. The billion-dollar facility, which will sit down the road from a major US
