SPHEREx produces first all-sky map, highlights entire universe in infrared light
After launching in March and collecting near-infrared data throughout 2025, NASA’s SPHEREx observatory has completed its first map of the universe. The map, which is comprised of 102 infrared wavelengths, will allow SPHEREx’s team and astrophysicists to research the source of the early universe’s inflation and the distribution of organic molecules throughout the universe. “It’s…

LIGO goes to space: ESA to proceed with LISA gravitational wave detector
On Thursday, the European Space Agency’s Science Programme Committee gave the go-ahead to the Laser Interferometer Space Antenna, or LISA project. This would mean the construction of the mission’s three spacecraft could begin as early as a year from now. While the interferometer would follow the same basic principles as the ground-based LIGO (Laser Interferometer…

Communal stargazing using your phone: The Unistellar eQuinox 2, reviewed
When we reviewed the Unistellar eVscope a couple of years ago, we came away impressed. It offered a communal stargazing experience that takes our ubiquitous smartphones and turns them into a way to view the heavens. Unistellar’s newest offering is the eQuinox 2, a lower-cost alternative to eVscope 2, taking all of the features from…
