While banning ozone-destroying gases such as CFCs has helped the ozone layer to recover, when combined with increased air pollution the impact of ozone...
Planets too close to their star are too hot (such as Venus), those too far, are too cold (like Mars), whereas planets in the habitable zone are just right....
In the search for life in the Universe, Earth provides a template of evolution for the one habitable planet we know. Earth’s atmospheric composition...
The aftermaths of supernovae always produce X-rays, but if the supernova’s blast wave strikes dense surrounding gas, it can produce a particularly large...
Atmospheric ozone and oxygen protect the biosphere of our planet against harmful ultraviolet radiation. In new research, astronomers modeled atmospheres...
In new research, paleontologists analyzed abundances of sunscreen-like chemicals in 800 fossil pollen grains from 250-million-year-old rocks in Tibet.
The...
The annual ozone hole over the South Pole reached an average area of 23.2 million km2 (8.9 million square miles) between September 7 and October 13, 2022,...
Hydroxyl radicals are highly reactive chemical species that attack most of the organic molecules.
High concentrations of OH radicals were found when people...
Iodine, the same chemical added as a nutrient to table salt, is an atmospheric trace element emitted from oceans that efficiently destroys ozone. Low ozone...
The Antarctica’s ozone hole has now reached its maximum size, according to an analysis of data collected by ESA’s Copernicus Sentinel-5P satellite.
This...
Multiple supernova explosions about 65 light-years away may have contributed to the ozone depletion and several subsequent extinction events at the Devonian-Carboniferous...
Taking advantage of a total lunar eclipse in January 2019, astronomers using the NASA/ESA Hubble Space Telescope have measured the amount of ozone in the...
The Atmospheric Chemistry Suite (ACS) aboard ESA’s ExoMars Trace Gas Orbiter (TGO) has spotted never-before-seen spectral signatures of ozone and carbon...
The newly-invented method, named the matrix assembly cluster source (MACS), involves no solvent and is a step change in the approach to water treatment...
High levels of damaging ultraviolet-B (UV-B) radiation collapsed forest ecosystems and killed off many species of fish and tetrapods at the end of the...
Using data from the Tropomi instrument on ESA’s Copernicus Sentinel-5 Precursor satellite (also known as Sentinel-5P), a team of scientists from the...
An international team of researchers led by Prof. Susan Solomon of the Massachusetts Institute of Technology (MIT) has identified the first ‘fingerprints...
European and Australian researchers have identified three new ozone-depleting chlorofluorocarbons, dubbed CFC-112, CFC-112a, CFC-113a, and one new ozone-depleting...
A new study published in the journal Nature Geoscience explains how global atmospheric circulation creates a previously undetected layer of ozone above...
