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.....»»
AI model harnesses physics to autocorrect remote sensing data
Turbulence, temperature changes, water vapor, carbon dioxide, ozone, methane, and other gases absorb, reflect, and scatter sunlight as it passes through the atmosphere, bounces off the Earth's surface, and is collected by a sensor on a remote sensing.....»»
Scientists find new way global air churn makes particles
You can think of our atmosphere as a big chemistry set, a global churn of gaseous molecules and particles that constantly bounce off and change each other in complicated ways. While the particles are very small, often less than 1% of the thickness of.....»»
Melting high-mountain glaciers would release greenhouse gases into atmosphere, suggest scientists
The retreat of high mountain glaciers has accelerated since the 1980s, resulting in increased glacier runoff. However, it remains uncertain whether melting mountain glaciers enhance or release greenhouse gases, and whether areas exposed to glacier re.....»»
Forest carbon storage has declined across much of the Western U.S., likely due to drought and fire
Forests have been embraced as a natural climate solution, due to their ability to soak up carbon dioxide from the atmosphere as they grow, locking it up in their trunks, branches, leaves, and roots. But a new study confirms widespread doubts about th.....»»

Evidence of water vapor detected in the atmosphere of Smertrios
Using the CARMENES spectrograph, astronomers have found evidence of water vapor in the atmosphere of a hot Saturn exoplanet designated HD 149026 b, dubbed Smertrios. The finding, reported in a research paper published on the preprint server arXiv, co.....»»
Deep learning model enhances maize phenotype detection and crop management
A research team has developed the Point-Line Net, a deep learning method based on the Mask R-CNN framework, to automatically recognize maize field images and determine the number and growth trajectory of leaves and stalks. The model achieved an objec.....»»
Repurposed technology used to probe new regions of Mars" atmosphere
Using the repurposed equipment, a team including Imperial College London researchers have measured parts of the Martian atmosphere that were previously impossible to probe. This includes areas that can block radio signals if not properly accounted fo.....»»
Study finds early-onset El Niño means warmer winters in East Asia, and vice versa
The phenomenon known as El Niño can cause abnormal and extreme climate around the world due to it dramatically altering the normal flow of the atmosphere. In Japan, historical data has shown that El Niño years tend to lead to warmer winters. This c.....»»
Pooping on the Moon Is a Messy Business
If humans are to return to the moon, space agencies and governments need to figure out the legal, ethical, and practical dimensions of extraterrestrial waste management......»»
Lava continues to flow from Iceland volcano but not at powerful level as eruption
Lava continued to spurt from a volcano in southwestern Iceland on Thursday but the activity had calmed significantly from when it erupted a day earlier......»»

How to watch Europe launch a new Earth observation satellite tonight
The European Space Agency will launch a satellite called EarthCARE to observe clouds and aerosols in the atmosphere tonight. Here's how to watch the launch......»»
Asian forests show resilience despite rising disturbances from climate change and human activities
Since 1850, global temperatures have been steadily rising. Human activities have significantly increased the emissions of greenhouse gases into the atmosphere, exacerbating the greenhouse effect and global warming. Forests in Asia have faced numerous.....»»
Tropical forest resilience to seasonal drought linked to nutrient availability
Tropical forests are highly productive ecosystems, accounting for nearly half of the global forest carbon sink. If tropical forests can no longer remove carbon dioxide from the atmosphere, the effects of climate change may become even more severe......»»
Video: Unraveling the mysteries of clouds
Clouds are one of the biggest mysteries in the climate system. They play a key role in regulating the temperature of our atmosphere. But we don't know how their behavior will change over time as Earth's atmosphere gets warmer. This is where EarthCARE.....»»
