Terrestrial and sub-Neptune exoplanets are expected to form in the inner regions of protoplanetary disks around their parent stars. Water plays a key role...
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...
Earth’s rotational pole has drifted toward 64.16°E at a speed of 4.36 cm per year during 1993-2010 due to groundwater depletion and resulting sea level...
Hygroscopic hydrogels are emerging as scalable and low-cost sorbents for atmospheric water harvesting, dehumidification, passive cooling, and thermal energy...
Phosphorus has not previously been detected in oceans beyond those on Earth and this discovery provides a promising step forward in our understanding of...
As Enceladus orbits rapidly around Saturn with a period of only 1.37 Earth days, the ejected water vapor is spread along and around its orbit, forming...
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...
The new observations from the Near-Infrared Spectrograph (NIRSpec) aboard the NASA/ESA/CSA James Webb Space Telescope show that the main-belt comet 238P/Read...
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...
Using spectral data from Webb’s Near-Infrared Spectrograph (NIRSpec), astronomers determined that the warm super-Earth Gliese 486b either has a water-rich...
Researchers at Washington State University have demonstrated a new synergistic carbon-capture strategy, i.e., using concrete washout water and biochar...
The first records of Greenland Vikings date to 985 CE. Archaeological evidence yields insight into how they lived, yet drivers of their disappearance in...
Scientists from China and the United States have analyzed the impact glass beads from a lunar soil sample returned by China’s Chang’e-5 mission.
Asteroid...
With ongoing carbon dioxide emissions from the burning of fossil fuels, the atmosphere of Earth heats up, which has dramatic consequences for the ice sheets....
The radar properties of icy satellites of Jupiter and Saturn commonly differ by more than an order of magnitude from those of rocky planets because of...
The previously unreconciled acceleration of 1I/2017 U1 ‘Oumuamua, a strange object of extrasolar origin discovered on October 19, 2017 by the Pan-STARRS...
A so-called light-toned deposit (LTD) in Eastern Noctis Labyrinthus, about 160 km (99.4 miles) north-west of Oudemans crater near Mars’ equator, presents...
Rocky exoplanets orbiting red dwarf (M-dwarf) stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets...
In new research, planetary scientists from the University of Maryland and elsewhere analyzed melted meteorites that had been floating around in space since...
