First measurement of isotopes in atmosphere of exoplanet
An international team of astronomers have become the first in the world to detect isotopes in the atmosphere of an exoplanet. It concerns different forms of carbon in the gaseous giant planet TYC 8998-760-1 b at a distance of 300 light years in the c.....»»
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......»»
New measurement captures clearer picture of our galaxy and beyond
With unique capabilities to track microwave energy fluctuations, a small observatory in the Andes mountains of northern Chile produced maps of 75% of the sky as part of an effort to measure the universe's origin and evolution more accurately......»»

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.....»»
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.....»»
14 parameters in one go: New instrument for optoelectronics
An HZB physicist has developed a new method for the comprehensive characterization of semiconductors in a single measurement. The "Constant Light-Induced Magneto-Transport (CLIMAT)" is based on the Hall effect and allows the recording of 14 different.....»»
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.....»»
Webb telescope spots hints that Eris, Makemake are geologically active
Webb measured isotopes at the edge of the Solar System, hinting at chemistry. Enlarge / Artist's conceptions of what the surfaces of two dwarf planets might look like. (credit: SWRI) Active geology—and the large-scale.....»»
New nuclei can help shape our understanding of fundamental science on Earth and in the cosmos
In creating five new isotopes, an international research team working at the Facility for Rare Isotope Beams (FRIB) at Michigan State University has brought the stars closer to Earth......»»
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.....»»
