The earliest atmosphere on Mercury
Mercury is a most unusual planet. The smallest planet in the solar system, and the closest planet to the sun, it is in a 3:2 spin resonance, slowly turning and experiencing scorching heat up to 430 degrees Celsius, and the night side frigid, down to.....»»
Study reveals accelerated soil priming under climate warming
A first-of-its-kind study led by researchers at the University of Oklahoma highlights a crucial biosphere feedback mechanism and its effects on releasing soil carbon into the atmosphere......»»
Image: ERS-2 buckles and bends during final farewell
Following a hugely successful mission and almost 30 years in orbit, ESA's ERS-2 reentered Earth's atmosphere at approximately 18:17 CET (17:17 UTC) on 21 February 2024......»»

Satellites are burning up in the upper atmosphere—what impact could this have on the Earth"s climate?
Elon Musk's SpaceX has announced it will dispose of 100 Starlink satellites over the next six months, after it discovered a design flaw that may cause them to fail. Rather than risk posing a threat to other spacecraft, SpaceX will "de-orbit" these sa.....»»
Ditching meat could release vital land to produce energy and remove carbon from the atmosphere—new study
A radical reduction in the amount of meat, dairy and other products sourced from animals is possible in the coming decades, as people turn to an increasing variety of alternatives. This would unlock vast amounts of land currently used to rear animals.....»»
Side-effects of expanding forests could limit their potential to tackle climate change—new study
Tackling climate change by planting trees has an intuitive appeal. They absorb the greenhouse gas carbon dioxide from the atmosphere without using expensive technology......»»
Earth"s early evolution: Fresh insights from rocks formed 3.5 billion years ago
Our Earth is around 4.5 billion years old. Way back in its earliest years, vast oceans dominated. There were frequent volcanic eruptions and, because there was no free oxygen in the atmosphere, there was no ozone layer. It was a dynamic and evolving.....»»
Old European satellite plunges harmlessly through the atmosphere over the Pacific
An old Earth-observing satellite fell out of orbit Wednesday and harmlessly broke apart over the Pacific......»»
Research shows how air pollution has offset expected increases in rainfall
We know that greenhouse gas emissions like carbon dioxide should increase rainfall. The emissions heat the atmosphere, causing a one-two punch: Warmer oceans make it easier for water to evaporate, and warmer air can hold more water vapor, meaning mor.....»»
Spacecraft looks like a "Star Wars" ship. It just crashed into Earth.
The large ERS-2 satellite fell through Earth's atmosphere and will largely burn up, the European Space Agency said. An image of the falling spacecraft looks like a "Star Wars" TIE fighter. UPDATE: Feb. 21, 2024, 3:30 p.m. EST In an update p.....»»
Spacecraft looks like a TIE fighter. It"s about to crash into Earth.
The large ERS-2 satellite will fall through Earth's atmosphere and burn up, the European Space Agency said. An image of the falling spacecraft looks like a "Star Wars" TIE fighter. After nearly three decades in space, a satellite the length of.....»»
Neanderthals" usage of complex adhesives reveals higher cognitive abilities, scientists discover
Neanderthals created stone tools held together by a multi-component adhesive, a team of scientists has discovered. Its findings, which are the earliest evidence of a complex adhesive in Europe, suggest these predecessors to modern humans had a higher.....»»
Possible atmospheric destruction of a potentially habitable exoplanet
Astrophysicists studying a popular exoplanet in its star's habitable zone have found that electric currents in the planet's upper atmosphere could create sufficient heating to expand the atmosphere enough that it leaves the planet, likely leaving the.....»»
Mercury levels in tuna remain nearly unchanged since 1971, study says
Tuna is one of the most popular seafoods worldwide. But this protein-rich fish can build up high levels of methylmercury from feeding on contaminated prey, like smaller fish or crustaceans. Despite efforts to reduce mercury emissions into the environ.....»»
Detecting atmospheric rivers with satellite observations
Atmospheric rivers (ARs) are filaments of intense moisture transport in the atmosphere. These weather systems drive a large fraction of the extreme precipitation events over coastal regions. Detecting ARs in satellite observations has long been a cha.....»»
Android 15 has launched in the form of a developer preview
The 2024 version of Android is now out in its earliest form, but you should wait until the betas at least......»»
Study finds oxygen rise in the tropical upper ocean during the Paleocene-Eocene Thermal Maximum
Oxygen is fundamental to sustaining life on Earth. The ocean gets its oxygen from its uppermost layers in contact with the atmosphere. As our planet continues to warm, the ocean is gradually losing its capacity to absorb oxygen, with severe consequen.....»»
Study shows methane emissions from wetlands increase significantly over high latitudes
Wetlands are Earth's largest natural source of methane, a potent greenhouse gas that is about 30 times more powerful than carbon dioxide at warming the atmosphere. A research team from the Department of Energy's Lawrence Berkeley National Laboratory.....»»
Astronomers investigate the atmosphere of a nearby cold brown dwarf
Using the James Webb Space Telescope (JWST), astronomers have observed a nearby cold brown dwarf designated WISEPA J182831.08+265037.8 (or WISE 1828 for short). The observations delivered important insights into the composition of the object's atmosp.....»»
