The first cosmic map generated thanks to NASA’s SPHEREx space telescope
NASA has published the first cosmic map generated using observations from its SPHEREx space telescope. In particular, these observations include 102 wavelengths in the near-infrared. What NASA has defined as 102 colors offer a wealth of different information about the observed objects, valuable in a variety of cosmological studies. The wealth of information is such that NASA treats them as if they had obtained 102 different maps.
