Study suggests the Moon is millions of years younger than previously thought

A new study suggests that the Moon is much younger than what was previously thought– about 85 million years younger. Lunar rock samples collected on the Apollo missions are not old enough to confirm the normally accepted 4.51 billion-year for the Moon's age,…

ESO telescope catches the disappearance of massive unstable star

Astronomers have discovered the absence of a massive unstable star in the Kinman Dwarf galaxy using ESO's Very Large Telescope (VLT). One explanation offered is the end of a luminous blue variable (LBV) eruption of a surviving star, with a mild drop in…

Unusual green glow detected for the first time in atmosphere of Mars

The European Space AGency's (ESA) Trace Gas Orbiter (TGO) has detected an unusual green glow for the first time in the atmosphere of Mars. According to the new study, the bright emission has been predicted to exist at Mars for around 40 years. "One of the…
