Atmospheric Chemistry

Planetary researcher Tereza Constantinou and her colleagues at the University of Cambridge have examined the chemical composition of the Venusian atmosphere and inferred that the planet's interior is too dry today for there ever to have been enough water for oceans to exist at its surface.

An international team of scientists, led by Profs. Daniel Strasser and Roi Baer from The Hebrew University of Jerusalem, has made an important discovery in molecular physics, revealing unexpected symmetry-breaking dynamics in ionized carbon dioxide dimers. The study uncovers new insights into the structural changes that occur when these molecular clusters are exposed to extreme ultraviolet (EUV) radiation.

New regulations, and satellites such as MethaneSat, very likely will not cut methane emissions. Natural gas industry economics will instead continue delaying their needed reduction

From microbes to mammoths, life has transformed Earth into one big living system, says Ferris Jabr, author of Becoming Earth: How Our Planet Came to Life

A new UC Riverside study shows soot from large wildfires in California traps sunlight, making days warmer and drier than they ought to be.

Astronomers have found that one of the lightest exoplanets ever seen, the young 'cotton candy' world V1298 Tau b, may be shrinking from the size of Jupiter...

Studying Venus' water loss can help scientists better understand how planets go from potentially habitable to incapable of supporting life.

Elizabeth Kolbert on why some leading geologists reject the "Anthropocene," a term used by scientists to describe this new age in which humans shape the Earth.

The space station has multiple instruments collecting climate-related data helping scientists solve the challenges created by climate change.

In honor of Women's History Month, we caught up with the ASIA-AQ team on the other side of the Earth and asked the women from Langley about their inspirations

Since "Anthropocene" was coined in 2000, it has increasingly defined our times as an age of human-caused planetary transformation.

Eighty-five percent of the Earth's air resides in the lowest layer of its atmosphere, or troposphere. Yet, major gaps remain in our understanding of the atmospheric chemistry that drives changes in the troposphere's composition.

There's a one in a billion chance it could hit somebody on the head. Europe's space agency doesn't know exactly when or where it will land.

A type of distant planet long thought to have water oceans on its surface may be too hot for liquid water, and magma oceans might be more likely

MIT Professor Susan Solomon won the 2023 VinFuture Award for Female Innovators in recognition of her contributions to understanding ozone depletion and the creation of the Montreal Protocol.

Information theory can help us decode signs of biological activity hiding in the atmospheres of distant exoplanets

Planetary scientists simulate how haze might be obstructing our view of exoplanet's atmospheres, and potentially alien water.

The wildfire smoke that smothered the U.S. Northeast last week has surprising connections to astrophysics—and to the historic search for our place in the cosmos

The global warming effect of leaked hydrogen is almost 12 times stronger than CO2, shows a new study by CICERO, a climate research center, published in Communications Earth & Environment.
