A large team of researchers affiliated with multiple institutions in the U.S., Spain, France and Finland has found that frequent dust devils and daytime upslope winds are the reason for Mars's constant atmospheric haze. In ...
Scientists on Earth will soon see our planet's atmospheric dust sources in high resolution, as a new state-of-the-art imaging spectrometer—developed by NASA's Jet Propulsion Laboratory (JPL) and Cornell University—aims ...

An international team of researchers has found via global modeling that loss of biocrusts due to global warming could result in an additional 15% more dust emitted into the atmosphere by 2070. In their paper published in ...
Atmospheric dust plays a key role in Earth's climate system. While it can have a positive impact, such as fertilizing the soil, dust can also have a negative impact on our planet's ecosystems, affecting everything from the ...

A pair of researchers at The Higgs Centre for Theoretical Physics in the U.K. has found evidence suggesting that strong vertical winds in the upper atmosphere could push bacteria higher than 120 km. In their paper published ...
Planetary scientist Erdal Yiğit, with George Mason University, has published a Perspective piece in the journal Science suggesting that upper atmospheric interactions with solar wind cannot fully explain the loss of surface ...
The interaction of dust particles in Martian dust storms may cause electric fields that are powerful enough to have charges that induce standing electromagnetic waves known as Sсhumann resonances. This is the conclusion ...
