ZTF J203349.8+322901.1, nicknamed Janus after the two-faced Roman god of transition, is a transitioning white dwarf with two faces: one side of its atmosphere...
New research from the University of Toronto shows that from approximately 2 billion until 600 million years ago, an atmospheric tide driven by the Sun...
Aside from the Moon, the brightest object in our night sky is planet Venus, whose thick cloud layer reflects around 75% of the Sun’s light. By comparison,...
Some steep slopes on Mars have gullies with morphologies suggesting that they were formed by a liquid. However, the planet’s current climate is not conducive...
Seven rocky planets orbit the nearby dwarf star TRAPPIST-1, providing a unique opportunity to search for atmospheres on small planets outside the Solar...
On January 15, 2022, Hunga Volcano in Tonga produced the most violent eruption in the modern satellite era, sending a water-rich plume at least 58 km (36...
Hygroscopic hydrogels are emerging as scalable and low-cost sorbents for atmospheric water harvesting, dehumidification, passive cooling, and thermal energy...
Precursors of the molecules needed for the origin of life may have been generated by chemical reactions promoted by meteoritic and volcanic particles approximately...
Astronomers using the Karl G. Jansky Very Large Array in New Mexico have observed a bright, compact spot centered at Uranus’ north pole at several wavelengths....
Recently, former and current government officials, legislators, and faculty in the United States have called for research on what their government terms...
The newly-discovered planet has a radius of 1.03 Earth radii and a temperature between 27 and 127 degrees Celsius (81-261 degrees Fahrenheit), with the...
Low frequency sounds can travel vast distances across our planet, carrying information about the events that generated them as well as the medium through...
Gliese 1214b is a so-called mini-Neptune, a smaller, denser version of Neptune that consists of a rocky core surrounded by a thick blanket of gas.
This...
Life most likely started during the Hadean Eon (4.5 to 4 billion years ago). However, the environmental conditions which contributed to the complexity...
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...
