About:
- Objective: The aim of this mission is to count the number of stars that exist in the Universe.
- How? The experiment is measuring a mysterious glow of infrared light that fills our skies called the cosmic infrared background, which is emitted by some of the most common stars.
Is it the first of its kind?
- While this is not the first time that such a mission has been undertaken, the CIBER-2 instrument has been improved upon to see if any stars had been undercounted in the previous counting attempts.
- The European Space Agency (ESA) infrared space observatory Herschel also counted the number of galaxies in infrared and measured their luminosity previously.
