Organic 'building blocks' discovered in Titan's atmosphere Posted: 2 years ago by AutumnLotus
Scientists analysing data gathered by the Cassini spacecraft have confirmed the presence of heavy negative ions in the upper regions of Titan’s atmosphere. These particles may act as organic building blocks for even more complicated molecules and their discovery was completely unexpected because of the chemical composition of the atmosphere (which lacks oxygen and mainly consists of nitrogen and methane).

Volcanic moon’s gassy mystery solved Posted: 2 years ago by AutumnLotus
Jupiter's volcanic moon Io is veiled by a thin atmosphere, but how much its volcanoes and chunks of frozen gas contribute to its atmosphere has puzzled scientists for decades. The New Horizons spacecraft recently documented the moon's glowing aurora, however, giving researchers a chance to solve the atmospheric mystery.

Why Sun's Atmosphere Is 'So Darned Hot' Posted: 3 months ago by AutumnLotus
Small, sudden bursts of heat and energy, called nanoflares, are responsible for the million-degree temperature of the sun's tenuous atmosphere, a new study reveals.

Space storm caught slamming into Earth's atmosphere Posted: 6 months ago by AutumnLotus
A space storm has been observed exploding from a central point in Earth's upper atmosphere for the first time. The result could one day lead to better predictions of the storms, which can harm satellites and power grids on the ground.

Cluster watches Earth’s leaky atmosphere Posted: 1 year ago by AutumnLotus
Oxygen is constantly leaking out of Earth’s atmosphere and into space. Now, ESA’s formation-flying quartet of satellites, Cluster, has discovered the physical mechanism that is driving the escape. It turns out that the Earth’s own magnetic field is accelerating the oxygen away.

NASA Selects 'MAVEN' Mission To Study Mars Atmosphere Posted: 1 year ago by AutumnLotus
NASA has selected a Mars robotic mission that will provide information about the Red Planet's atmosphere, climate history and potential habitability in greater detail than ever before.
I posted this because it has MAVEN.

Origin of "Breathable" Atmosphere on Earth Found Posted: 2 years ago by AutumnLotus
Geologists have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today. The study suggests that upheavals in the earth’s crust initiated a kind of reverse-greenhouse effect 500 million years ago that cooled the world’s oceans, spawned giant plankton blooms, and sent a burst of oxygen into the atmosphere.

Saturn Does the Wave in Upper Atmosphere Posted: 2 years ago by AutumnLotus
Two decades of scrutinizing Saturn are finally paying off, as scientists have discovered a wave pattern, or oscillation, in Saturn's atmosphere only visible from Earth every 15 years.

Tiny Flares Responsible for Outsized Heat of Sun's Atmosphere Posted: 3 months ago by kakana
Solar physicists at NASA have confirmed that small, sudden bursts of heat and energy, called nanoflares, cause temperatures in the thin, translucent gas of the sun's atmosphere to reach millions of degrees.

Origin of Hiss in Upper Atmosphere Identified Posted: 2 years ago by AutumnLotus
Scientists have solved a 40-year-old puzzle by identifying the origin of the intense radio waves in the Earth's upper atmosphere that control the dynamics of the Van Allen radiation belts — belts consisting of high-energy electrons that can damage satellites and spacecraft and pose a risk to astronauts performing activities outside their spacecraft.

Setting stars reveal planetary secrets Posted: 2 years ago by AutumnLotus
Watching the stars set from the surface of the Earth may be a romantic pastime but when a spacecraft does it from orbit, it can reveal hidden details about a planet’s atmosphere. It works by watching stars from space, while they drop behind the atmosphere of a planet under investigation, before disappearing from view below the planet’s horizon.

Scientists enhance Mother Nature's carbon handling mechanism Posted: 2 years ago by AutumnLotus
Taking a page from Nature herself, a team of researchers developed a method to enhance removal of carbon dioxide from the atmosphere and place it in the Earth's oceans for storage.

Lunar eclipse may shed light on climate change Posted: 2 years ago by AutumnLotus
Last month's lunar eclipse not only treated skygazers to a ruddy view of the Moon – it revealed that Earth's atmosphere contains little light-blocking volcanic dust.
Some researchers say the low volcanic dust levels in the atmosphere over the last dozen years could be contributing to global warming, but others dispute the claim.

A dash of lime - a new twist that may cut CO2 levels back to pre-industrial levels Posted: 1 year ago by AutumnLotus
Scientists say they have found a workable way of reducing CO2 levels in the atmosphere by adding lime to seawater. And they think it has the potential to dramatically reverse CO2 accumulation in the atmosphere.

'Chemical equator' keeps southern air clean Posted: 1 year ago by AutumnLotus
A boundary of air, wrapped like a belt around the earth's equator, is keeping the polluted atmosphere of the Northern Hemisphere separate from the relatively pristine south, say UK researchers.

Potential Sources Of 'Rain-Making' Bacteria In The Atmosphere Identified Posted: 1 year ago by AutumnLotus
Brent Christner, assistant professor of biological sciences at LSU, recently found evidence that bacteria and biological cells are the most efficient ice-forming catalysts in precipitation from locations around the globe. The formation of ice in clouds is important in the processes that lead to snow and rain.
