Concentration of N2O in the atmosphere increases strongly and speeds up climate change. In addition to CO2 and methane, it is the third important greenhouse gas emitted due to anthropogenic activities.
A team of U.S. astronomers have created the Pan-STARRS1 Source Types and Redshifts with Machine Learning (PS1-STRM), the world’s largest three-dimensional astronomical catalog.
A team of researchers claims they've discovered the amino acid glycine in Venus' atmosphere. There are about 500 known amino acids, but only 20 are present in the genetic code. Glycine is the simplest of them.
The planet just recorded its hottest September since at least 1880. The data, most of which was released Wednesday, shows that 2020 is on track to be one of the hottest years on record.
The Ozone hole over the Antarctica continent has become unprecedentedly deeper and larger in the last 15 years, the latest finding of the World Meteorological Organization has shown. It has reached its peak of at 24 mil square km.
Since the mid-1990s, coral in the Great Barrier Reef has declined by more than 50%. The research spanned the entire 2,300 km of the Great Barrier Reef and found a disturbing loss at pretty much every level.
