15 Greatest Discoveries from NASA’s Spitzer Space Telescope

3. Milky way map

Spitzer discovered one of the most extensive maps of Milky Way galaxy. Spitzer has identified many distant galaxy clusters. Map data provided by GLIMPSE360 Galactic Legacy Mid-Plane Survey Extraordinary 360 project.

Infrared light of Spritzer helps a lot to detect the Milky Way map infrared light can be penetrated easily industrial region as compared to visible light so that’s why spritzer displayed the best Milky Way map.

1. Seven Earth-size planets

Spitzer conjointly aided within the discovery of planets on the far side our system, as well as the detection of seven Earth-size planets orbiting the star TRAPPIST-1, among alternative accomplishments.TRAPPIST-1 orbited by seven earth-size planets. This is an amazing planetary system in which the “habitable zone” where the temperature is in accordance to the planets three planets sit in it.

Spitzer determined the number of planets orbiting The star here infrared light also worked well for deep analysis. The results told us about TRAPPIST-1 star that this is cooler than the sun.
