The newly launched NASA observatory, SPHEREx, aims to study the universe’s evolution by mapping the entire sky and observing hundreds of millions of galaxies. The spacecraft, launched atop a SpaceX Falcon 9 rocket from Vandenberg Space Force Base, will use 102 different colors of infrared light to gather data on the composition, density, temperature, and chemical makeup of celestial objects. This data will help scientists unravel the mysteries of how galaxies form, trace the origins of water in the Milky Way, and understand what happened in the immediate aftermath of the Big Bang. The $488 million mission is set to survey the sky four times over two years, providing valuable insights into the history and development of the universe. The launch was delayed multiple times but finally took place on Tuesday evening. Additionally, the observatory’s instruments will allow researchers to use spectroscopy to analyze the gathered infrared light, providing a more detailed understanding of the characteristics of galaxies. Through this mission, NASA hopes to shed light on the earliest moments of the universe and contribute to expanding our knowledge of the cosmos.
