How do you recognize the atmosphere of extraterrestrial lava worlds?
In the past 30 years, more than 5,000 planets have been discovered outside our solar system. One common exoplanet is the lava world, a hot super-Earth with oceans of liquid lava. Mantas Zilinskas developed models to simulate possible atmospheres of t.....»»
Old satellite to burn up over Pacific in "targeted" re-entry first
After 24 years diligently studying Earth's magnetic field, a satellite will mostly burn up over the Pacific Ocean on Sunday during a "targeted" re-entry into the atmosphere, in a first for the European Space Agency as it seeks to reduce space debris......»»
AI shines a new light on exoplanets
Researchers from LMU, the ORIGINS Excellence Cluster, the Max Planck Institute for Extraterrestrial Physics (MPE), and the ORIGINS Data Science Lab (ODSL) have made an important breakthrough in the analysis of exoplanet atmospheres......»»
Study shows how amateur astronomers can aid in Jupiter weather monitoring
Jupiter's striking appearance comes from its stormy atmosphere. Swirling clouds surround the gas giant, and their distribution reflects the planet's weather. Scientists have used professional observatories such as the Very Large Telescope in Chile (w.....»»
Eclipses create atmospheric gravity waves, student teams confirm
Student teams from three U.S. universities became the first to measure what scientists have long predicted: eclipses can generate ripples in Earth's atmosphere called atmospheric gravity waves. The waves' telltale signature emerged in data captured d.....»»
Astronaut captures a meteor exploding in the atmosphere over Earth
An incredible new video taken by an astronaut aboard the International Space Station shows a meteor exploding as it hits the planet's atmosphere......»»
More water worlds than we thought might support life
Too much water on exoplanet surfaces would mean high pressure ices, not life. Enlarge / High pressure ices near the crust are a feature of water-rich worlds.` (credit: Benoit Gougeon (University of Montreal)) The possibi.....»»
Astronomers discover iron winds on an ultra-hot exoplanet
An international team of astronomers, including scientists from the University of Geneva (UNIGE) and the PlanetS National Center of Competence in Research, has identified the presence of iron winds in the atmosphere of the ultra-hot Jupiter WASP-76 b.....»»
Small, harmless asteroid burns up in Earth"s atmosphere over the Philippines
A small asteroid discovered on Wednesday harmlessly burned up in Earth's atmosphere the same day, NASA said......»»
Soil treated with organic fertilizers stores more carbon, study finds
With carbon dioxide levels in the atmosphere increasing in recent decades, there is a growing urgency to find strategies for capturing and holding carbon......»»
Scientists uncover hidden source of snow melt: Dark brown carbon
Wildfires leave potent climate heaters behind in their wake, particles that enhance the absorption of sunlight and warm the atmosphere. Dropped on snow like a wool poncho, these aerosols darken and decrease the surface reflectance of snowy places......»»
Sulfurous acid detected in gas phase under atmospheric conditions for first time
Once again, the atmosphere amazes us with its diverse chemical processes. For the first time, researchers at the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig have demonstrated the existence of sulfurous acid (H2SO3) under atmospher.....»»
Webb discovers six new "rogue worlds" that provide clues to star formation
Rogue planets, or free-floating planetary-mass objects (FFPMOs), are planet-sized objects that either formed in interstellar space or were part of a planetary system before gravitational perturbations kicked them out......»»
The impact of human activity on air quality: A look at aerosol pollution before and after the Industrial Revolution
A recent study led by the Institute of Atmospheric Physics at the Chinese Academy of Sciences sheds new light on how human activities have altered the composition of the atmosphere over time, particularly focusing on secondary organic aerosols (SOA)......»»
Teens recognize risk behavior in movies and series, but are not always critical
When teens see risk behavior such as drinking, smoking or drug use in movies or series, they sometimes find it difficult to define whether it's realistic or not. They recognize stereotypes but cannot always interpret it critically. This is according.....»»
In six new rogue worlds, Webb Telescope finds more star birth clues
The James Webb Space Telescope has spotted six likely rogue worlds—objects with planetlike masses but untethered from any star's gravity—including the lightest ever identified with a dusty disk around it......»»
US grid adds batteries at 10x the rate of natural gas in first half of 2024
By year's end, 96 percent of the US's grid additions won't add carbon to the atmosphere. (credit: DOE) While solar power is growing at an extremely rapid clip, in absolute terms, the use of natural gas for electricity pr.....»»
Iceland"s volcanic eruption slows as lava flows from second fissure
Icelandic authorities said Friday that a second fissure had formed on the southwestern Reykjanes peninsula, but volcanic activity had decreased after lava started spewing forth for the sixth time in the region since December......»»
Carbon emissions from forest soil will likely grow with rising temperatures
The soils of northern forests are key reservoirs that help keep the carbon dioxide that trees inhale and use for photosynthesis from making it back into the atmosphere. But a unique experiment led by Peter Reich of the University of Michigan is showi.....»»
From sun to Earth: A new network for comprehensive space weather monitoring
There's a lot going on between Earth's atmosphere and the sun. Accurately forecasting conditions in this area of space is challenging but critical to the safety of astronauts, satellites, and even ground-based systems such as power grids. Doing so re.....»»
An Iceland volcano erupts again but spares the nearby town of Grindavik for now
A volcano in southwestern Iceland erupted Thursday evening for the sixth time since December, spewing red lava through a new fissure on the Reykjanes Peninsula......»»
