NASA is coming up with its new space telescope that is going to search for the History of the Universe and epoch of Reionization.
To map the entire sky in order to study the rapid expansion of the universe post big bang is this observatory being launched. It is also going to search for a young planetary system and galactic history. The space telescope SPHEREx has already entered phase C in NASA lingo. It is managed by NASA’s Jet Propulsion Laboratory situated in South California. It is being planned to be launched between June 2024 to April 2025.
The instrument is the size of a subcompact car and it will use a technique of spectroscopy to detect near-infrared light or frequencies that are beyond human visibility. It is going to break infrared light into its components like a prism and analyze it to reveal the composition of the element which absorb the particular wavelength. It will create a huge database of stars, galaxies, nebulas, and remnant light coming from the past to study its history. During its two years of mission, it would map the entire sky four times. The full sky spectroscopy is going to map in near-infrared and observe 102 near-infrared colors.
It has got 3 main goals:
- Firstly to look for anything that might have occurred less than a billionth of a billionth second after the big bang by analyzing the primordial light.
- To study the history of galaxy formation.
- To look for ice and frozen organic molecules around the newly forming stars in our galaxy.
