A new study found if some planets were habitable, life would become extinct right after its origin due to extreme heating or cooling.
Scientists found one of the most luminous supernova, ASAS-SN-15lh, which is 50 times more luminous than the Milky Way galaxy.
Apparently a distant and quiet quasar SDSS J1011+5442 has run out of gas.
NASA's Cassini spacecraft revisited a mysterious landscape on Enceladus after ten years during its final close flyby.

The Hubble Space Telescope captured the image of two galaxies as they smashed into each other, forming a giant elliptical galaxy, NGC 3597.
Astronomers used data from NASA's Great Observatories, which enabled them to carry out a detailed study of a large young galaxy cluster and they even weighed the mass of the galaxy.
