Registration is open for digital content creators to attend the launch of NASA’s Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission, and NASA’s Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission. SPHEREx…

The space telescope will detect over 100 colors from hundreds of millions of stars and galaxies. Here’s what astronomers will do with all that color. NASA’s SPHEREx mission won’t be the first space telescope to observe hundreds of millions of…

Some 13.8 billion years ago, the universe began with a rapid expansion we call the big bang. After this initial expansion, which lasted a fraction of a second, gravity started to slow the universe down. But the cosmos wouldn’t stay…

Key elements are coming together for NASA’s SPHEREx mission, a space telescope that will create a map of the universe like none before. NASA’s SPHEREx space telescope is beginning to look much like it will when it arrives in Earth…

The SPHEREx mission will create a 3D map of the entire sky. Its cutting-edge instruments require a custom-built chamber to make sure they’ll be ready to operate in space. After three years of design and construction, a monthlong boat ride…

The SPHEREx mission will have some similarities with the James Webb Space Telescope. But the two observatories will take dramatically different approaches to studying the sky. NASA’s upcoming SPHEREx mission will be able to scan the entire sky every six…

The observatory will map the entire sky to study the rapid expansion of the universe after the big bang, the composition of young planetary systems, and the history of galaxies. NASA’s upcoming space telescope, the Spectro-Photometer for the History of…
