Visualization of the SPHEREx Galaxy Catalog
SPHEREx team members from Argonne National Laboratory have created an exciting new visualization of the galaxy catalog that SPHEREx will generate (if approved by NASA, that is). Specifically, the Argonne scientists created a fly-through movie demonstrating how SPHEREx will map out the extragalactic sky in three dimensions. Watch the video below to see how SPHEREx will reveal the large-scale structure of the universe (galaxy clusters and voids, visible in blue and black) by measuring the redshifts of nearly 500 million galaxies with a precision of 10%. But there's more -- SPHEREx will measure the redshifts of another 16 million galaxies with an exquisite 0.3% precision. More about the groundbreaking science this will enable.

NASA’s SPHEREx Observatory Completes First Cosmic Map Like No Other
Launched in March, NASA’s SPHEREx space telescope has completed its first infrared map of the entire sky in 102 colors. While not visible to the human eye, these 102 infrared wavelengths of light are prevalent in the cosmos, and observing the entire sky this way enables scientists to answer big questions, including how a dramatic event that occurred in the first billionth of a trillionth of a...

SPHEREx has made detailed multi-spectral observations of interstellar comet 3I/ATLAS, detecting an abundance of carbon dioxide gas in its coma (the extended gaseous atmosphere of a comet) and water ice in its nucleus. The observations were made between Aug. 7 to Aug. 15, when the object was about 290 million miles (470 million kilometers) from the Sun.

NASA’s newest astrophysics space telescope launched in March on a mission to create an all-sky map of the universe. Now settled into low-Earth orbit, SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) has begun delivering its sky survey data to a public archive on a weekly basis, allowing anyone to use the data to probe the secrets of the cosmos.
