NASA’s Spitzer Space Telescope was able to detect a super Earth’s direct light for the first time using its sensitive heat-seeking infrared vision. Super Earth‘s are more massive than Earth but lighter than gas giants like Neptune. Image credit: NASA/JPL-Caltech
The star-forming region, 30 Doradus, is one of the largest located close to the Milky Way and is found in the neighboring galaxy, Large Magellanic Cloud. About 2,400 massive stars in the center of 30 Doradus, also known as the Tarantula Nebula, are producing intense radiation and powerful winds as they blow off material.
