On May 24, 2023, as part of the A Sign in Space project, ESA’s ExoMars Trace Gas Orbiter (TGO) will transmit an encoded message to Earth to simulate...
Recently, former and current government officials, legislators, and faculty in the United States have called for research on what their government terms...
Glacial cycles during the Early Pleistocene epoch are characterized by a dominant 41,000-year periodicity and amplitudes smaller than those of glacial...
Low frequency sounds can travel vast distances across our planet, carrying information about the events that generated them as well as the medium through...
Mobile communication towers represent a relatively new but growing contributor to the total radio-leakage associated with planet Earth. In new research,...
Life most likely started during the Hadean Eon (4.5 to 4 billion years ago). However, the environmental conditions which contributed to the complexity...
One of the biggest challenges to growing food on Mars is the presence of perchlorate salts, which have been detected in the Martian regolith (soil) and...
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...
ESA’s Jupiter Icy Moons Explorer (JUICE) has taken its first monitoring camera images showing part of the spacecraft with our home planet as a stunning...
Phosphate minerals such as those in the apatite group tend to be the dominant forms of phosphorus in minerals on the Earth’s surface. Phosphates can...
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....
Diverse branching forms have evolved multiple times across the tree of life to facilitate resource acquisition and exchange with the environment. As an...
In new research, planetary scientists from the University of Maryland and elsewhere analyzed melted meteorites that had been floating around in space since...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected gaseous water in the planet-forming disk around V883 Orionis, a...
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...
The new model provides a high-resolution understanding of how today’s geophysical landscapes were created and how millions of tons of sediment have flowed...
Previous research estimated that it took hundreds of million years for early Earth’s magma ocean to solidify, but new research narrows these large uncertainties...
Stunning radar images of the near-Earth asteroid 2011 AG5 were obtained from January 29 to February 4, 2022, by the powerful 70-m (230-foot) Goldstone...
The newly-detected molten rock layer is located about 150 km (93 miles) from the surface of our planet and is part of the asthenosphere, which sits under...
A small near-Earth asteroid designated 2023 BU made its closest approach on January 26, 2023 at 7:29 p.m. EST (4:29 p.m. PST, or January 27, 2023 at 00:29...
