NASA's SPHEREx and PUNCH missions successfully launched aboard a SpaceX Falcon 9 rocket, marking a significant step in space exploration. SPHEREx will map the entire sky in infrared light, studying galaxies and cosmic evolution,

Spherex (the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) will survey hundreds of millions of galaxies and "their combined cosmic glow" to give scientists new "insights into the universe's evolution since the Big Bang ", said The Independent.

A new NASA observatory launched into space Tuesday on a mission that could help scientists unravel what happened in the first fractions of a second after the Big Bang.
