Particulate emission from cooking stays longer in air than earlier thought

This should be taken into account for city planning but should also look at ways air can be better filtered, especially in fast food industries.

Water vapour from Mars is sent high into atmosphere where it gets lost in space

Mars continues to lose water today as vapour is transported to high altitudes after sublimating from the frozen polar caps during warmer seasons.

Odd carbon-based molecule found in atmosphere of Saturn's moon Titan

Instead of oxygen in its atmosphere like Earth, Titan has small amounts of methane, much like the early stages of our home world.

Oceans around the world have captured 10 percent of global carbon emission, new study suggests

The researchers part of the study calculated a time history of ocean-atmosphere CO2 fluxes (or movement) from 1992 to 2018.

Carbon emissions are chilling the atmosphere 90km above Antarctica, at the edge of space

In the high atmosphere above Antarctica, carbon dioxide and other greenhouse gases do not have the warming effect they do in the lower atmosphere

Where are the airborne plastics? Scientists find they are in the air we breath, the wind and the skies

Microplastics equivalent to123 million and 300 million plastic bottles rain down in America's western national parks and wilderness areas.

Early Earth had an atmosphere rich in carbon dioxide, claims study looking at ancient meteorites

Our planet is pelted with space dust and tiny meteorites daily, which make their way through the atmosphere and collect on the surface.

NASA's HabEx telescope proposed to seek out Earth-like exoplanets in our galaxy

The telescope, if approved, will have a mission life of 5 years and four instruments that will help in its mission.

Swiss startup ClearSpace signs contract with ESA to make space debris-free

The mission, ClearSpace-1, is to find and capture Vespa’s upper stage left in orbit after Vega's launch in 2013.

Understanding Saturn's moon Titan's seasons might provide insights about Earth's climate

Titan is the only body in the solar system, other than Earth, with a significant atmosphere and liquid surface lakes.
