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.
