Less than a year into its mission, NASA’s SPHEREx has already completed its first full survey of the sky, producing a near-infrared map that captures the entire cosmos in a staggering 102 colors.

Astronomers have produced the most detailed map yet of dark matter, revealing the invisible framework that shaped the Universe long before stars and galaxies formed. Using powerful new observations ...

This new map is not only the most detailed view of the universe’s invisible scaffolding to date, it also allows astronomers to look deeper into cosmic history. Reading time 3 minutes Dark matter—the ...

Are we alone in the universe? It’s the kind of question that fuels debates, History Channel marathons, and real-world space missions. The new documentary Starman dives straight into that mystery by ...
