Articles about 'atmosphere'

A team of astronomers has found that Venus has never been habitable, despite decades of speculation that our closest planetary neighbour was once much more like Earth than it is today.

Pollutants preserved in Antarctic ice document historic fires in the Southern Hemisphere, offering a glimpse at how humans have impacted the landscape and providing data that could help scientists understand future climate change.

Researchers may have identified the missing component in the chemistry of the Venusian clouds that would explain their colour and 'splotchiness' in the UV range, solving a longstanding mystery.

Stratospheric clouds over the Arctic may explain the differences seen between the polar warming calculated by climate models and actual recordings, according to researchers from the University of Cambridge and UNSW Sydney.

Researchers have found that the cooling effect that volcanic eruptions have on Earth's surface temperature is likely underestimated by a factor of two, and potentially as much as a factor of four, in standard climate projections.

Researchers have developed a new method for assessing the impacts of ozone-destroying substances that threaten the recovery of the ozone layer. 

The unusual behaviour of sulphur in Venus’ atmosphere cannot be explained by an ‘aerial’ form of extra-terrestrial life, according to a new study.

Dr Maria Russo is a Research Associate in the Department of Chemistry, where she studies the physical and chemical processes at work in the atmosphere. Here, she tells us about the links between climate and air pollution, the excitement of 'blue-skies' research, and achieving work/life balance while raising a family.

The chemical composition of gases emitted from volcanoes – which are used to monitor changes in volcanic activity – can change depending on the size of gas bubbles rising to the surface, and relate to the way in which they erupt. The results, published in the journal Nature Geoscience, could be used to improve the forecasting of threats posed by certain volcanoes. 

An international team of astronomers has detected titanium oxide in the atmosphere of an exoplanet for the first time. The results, reported in the journal Nature, provide unique information about the chemical composition and the temperature and pressure structure of the atmosphere of this unusual and very hot world.
