NASA's SPHEREx observatory has completed its first map of the entire sky over Earth, and it is incredible.

"It's incredible how much information SPHEREx has collected in just six months — information that will be especially valuable when used alongside our other missions’ data to better understand our universe," Shawn Domagal-Goldman, director of the Astrophysics Division at NASA Headquarters in Washington, said in a statement. "We essentially have 102 new maps of the entire sky, each one in a different wavelength and containing unique information about the objects it sees.

"I think every astronomer is going to find something of value here, as NASA's missions enable the world to answer fundamental questions about how the universe got its start, and how it changed to eventually create a home for us in it."

SPHEREx, which stands for the "Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer," orbits Earth just under 15 times per day from the North Pole to the South Pole.

As it does, this conical spacecraft captures 3,600 images throughout each of its orbits, with the orbit of Earth around the sun shifting the space observatory's field of view.

Beginning operations in May, it took SPHEREx until this month to complete its first map of the entire sky over our planet. During its primary mission lasting two years, the spacecraft is expected to complete another three all-sky scans. This data will be merged with the existing map to create an even more detailed picture of the sky over Earth.

"SPHEREx is a mid-sized astrophysics mission delivering big science," JPL Director Dave Gallagher said. "It's a phenomenal example of how we turn bold ideas into reality, and in doing so, unlock enormous potential for discovery."
