Atmosphere

While Mars may be the most likely place we might find life beyond Earth, it's not alone. High in the atmosphere of Venus, astronomers have made the startling discovery of a gas called phosphine – a strong contender for a sign of microbial life.

A few years ago researchers discovered bacteria in Antarctica that could survive on nothing but air. Now the team has found evidence of this handy ability in other cold desert locations. The finding could have implications for life beyond Earth.

Home to constant turbulent weather and the Great Red Spot – a storm bigger than Earth – Jupiter is the storm capital of the solar system. Now NASA’s Juno mission has discovered two new quirks of these storms – shallow lightning and “mushball” hail.

A NASA spacecraft has observed a pulsing glow coming from Mars. Huge spots of ultraviolet light were seen in the night sky, pulsing with uncanny regularity – exactly three times every night. The find highlights the Red Planet's atmospheric processes.

NASA has released a time-lapse video of our Sun that condenses 10 full years of solar observations into a 61 minute movie. The shots were taken by the Solar Dynamics Observatory, which has been keeping vigil over our parent star for a decade.

Turns out the Red Planet is a little more green than we thought. The ExoMars Trace Gas Orbiter (TGO) has detected a tinge of green in the atmosphere, making it the first time this aurora-like glow has been spotted around a planet other than Earth.

Current levels of carbon dioxide in the atmosphere are the highest they’ve been in a long time. According to a new study of fossil plant matter, CO2 concentrations haven’t been this high in at least 23 million years, and have never shot up this fast.

When did Earth's plate tectonics begin? A new study from Yale University claims to have found evidence that plate tectonics started about a billion years earlier than is currently thought, which places it very soon after the planet’s formation.

A new study has revealed that a cataclysmic disruption of Earth’s protective ozone layer may have allowed damaging levels of ultraviolet (UV) radiation to saturate the Earth 359 million years ago, triggering a global mass extinction.

Using what is known as the “lucky imaging” technique, scientists have created one of the sharpest infrared images of Jupiter ever taken from Earth, helping to reveal its weather systems, lightning and iconic Great Red Spot in exciting new detail.

Life continually outdoes expectations. A new study from MIT has found that E. coli and yeast can survive in an atmosphere made up of 100 percent hydrogen – and that could have fascinating implications for life on other planets.

Astronomers may have found a world where it rains iron. The exoplanet is exposed to thousands of times the radiation that the Earth receives from the Sun, rendering the surface hot enough to vaporize metals that later fall as rain.
