Through a combination of theoretical models and Infrared observations, Researchers found a specific group of Asymptotic Giant Branch (AGB) stars that shrouded in a high fraction of iron dust. This latest research, published in the journal ‘The Astrophysical Journal Letters’, compared the Infrared observations of the Spitzer Space Telescope with the theoretical models of…
Researchers propose that TRAPPIST-1e resembles Earth the most and it has an Oxygen-rich atmosphere to go with it. TRAPPIST-1 is a small, cool dwarf star located 39 light years or 235 trillion miles from our Sun. It is orbited by seven terrestrial (Earth-like) planets. These planets are temperate, which means the conditions there allow water…
Spitzer has been amazing us for 15 years now through its marvelous discoveries. Spitzer Space Telescope was launched on 25th August 2003 by NASA. The primary mission of this telescope was 2.5 years long and it was scheduled for that but it outlasted all the estimates of its lifetime and is still hovering in space.…
Current observations of ultra-hot planets by NASA’s Hubble and Spitzer space telescopes mystifies theorists. The planetary spectra suggest unusual compositions. A team of researchers from the Arizona State University explained in their recently published study that the gas-rich planets have basically normal compositions when we are relying on the known planet formation. The difference is…
