Using spectral data from Webb’s Near-Infrared Spectrograph (NIRSpec), astronomers determined that the warm super-Earth Gliese 486b either has a water-rich...
Terbium, a chemical element with the symbol Tb and atomic number 65, has never before been seen in an exoplanet atmosphere.
This illustration shows how...
The aftermaths of supernovae always produce X-rays, but if the supernova’s blast wave strikes dense surrounding gas, it can produce a particularly large...
Atmospheric ozone and oxygen protect the biosphere of our planet against harmful ultraviolet radiation. In new research, astronomers modeled atmospheres...
Researchers at Washington State University have demonstrated a new synergistic carbon-capture strategy, i.e., using concrete washout water and biochar...
New images from the NASA/ESA/CSA James Webb Space Telescope show the ice giant Uranus, its faint rings and several moons.
This image of Uranus, captured...
The most feasible explanation is that icy ring particles raining down onto Saturn’s atmosphere cause this heating, according to a team of astronomers...
The dayside of TRAPPIST-1b, the innermost planet in the seven-planet system TRAPPIST-1, has a temperature of about 227 degrees Celsius (441 degrees Fahrenheit),...
To facilitate studies of exo-Venus candidates, astronomers from the University of California, Riverside, the University of California, Santa Cruz, Brown...
In the lower atmosphere of Earth, oxygen contains a higher fraction of the heavy isotope 18O than ocean water does. This enrichment is a signature of biological...
‘Sun rays’ are also known as crepuscular rays, from the Latin word for twilight. It was the first time sun rays have been so clearly viewed on Mars.
This...
Frictional electrification is a common process in the Solar System, with Martian dust activities known to be a powerful source of electrical charge buildup....
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have validated the discovery of a warm, 0.99 Earth-radius exoplanet interior to the habitable...
In new research, paleontologists analyzed abundances of sunscreen-like chemicals in 800 fossil pollen grains from 250-million-year-old rocks in Tibet.
The...
Using data from NSF’s Karl G. Jansky Very Large Array (VLA), the Atacama Large Millimeter/submillimeter Array (ALMA) and NASA’s Juno spacecraft, two...
Using data from the NASA/ESA Hubble Space Telescope and NASA’s retired Spitzer space telescope, astronomers have discovered that two exoplanets around...
Titan, the largest moon of Saturn, is the only moon in the Solar System with a dense atmosphere, and it is also the only planetary body other than Earth...
