NASA says its SPHEREx space observatory is ready to embark on its expansive mission. As of May 1, the spacecraft has begun imaging a 3D map of the entire sky and its hundreds of millions of galaxies.

Just wow!" SPHEREx works differently than space telescopes like the Hubble and James Webb, NASA said. It takes a broader view of the sky than previous models, and will map the entire celestial sky ...

The cone-shaped Spherex — at 1,110 pounds (500 kilograms) or the heft of a grand piano — will take six months to map the entire sky with its infrared eyes and wide field of view.

Around 16-17 June, Mars will appear to pass close to Regulus, the bright star at the heart of the constellation Leo, the lion ...

When I say NASA finally turned ... SPHEREx will snap 3,600 images of the sky each day, capturing the light coming our way from hundreds of millions of galaxies to chart their position.
