NASA’s Perseverance rover has explored and sampled igneous and sedimentary rocks within Jezero crater to characterize early Martian geological processes...
White dwarfs are the dense cores left behind when stars exhaust their fuel and collapse. They are Earth-sized stellar embers weighing typically half as...
The Sun rarely produced extreme solar particle events, orders of magnitude stronger than everything directly observed. Their enormous power can greatly...
NASA’s Curiosity rover has found evidence of a carbon cycle on ancient Mars, bringing scientists closer to an answer on whether the planet was ever capable...
Paleontologists have examined teeth of Teleoceras major — an extinct species of rhinocerotid that lived in North America from 17.5 to 5 million years...
The Sample Analysis at Mars instrument onboard NASA’s Curiosity rover has detected decane, undecane, and dodecane molecules in a sample from Gale crater.
This...
Organometallic molecules consist of a metal ion surrounded by a carbon-based framework. They are relatively common for early actinide elements like uranium...
Wolf-Rayet 140 (also known as WR 140 or HD 193793) is a system of two massive stars located some 5,000 light-years away in the constellation of Cygnus....
Bright, twisted light can be produced thanks to nanostructured filaments with twisted geometry, according to scientists at the University of Michigan.
Planck’s...
A new class of atomically dispersed nickel catalysts directly converts captured carbon dioxide (CO2) to methane (CH4), according to Dr. Tomaz Neves-Garcia,...
Carbonate minerals are of particular interest in paleoenvironmental research as they are an integral part of the carbon and water cycles, both of which...
Using data from the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected carbon dioxide...
Geological observations of Mars indicate a dense early atmosphere ranging from 0.25 to 4 bar of carbon dioxide. But 3.5 billion years ago, the Martian...
A new biomaterial called C-ELM incorporates living cyanobacteria into translucent panels that can be mounted on to the interior walls of buildings. As...
In lunar regolith samples collected by China’s Chang’e-5 probe, planetary scientists have identified few-layer graphene formed together with complex...
Very-low-mass stars host orbiting rocky exoplanets more frequently than other types of stars. The compositions of those planets are largely unknown but...
Gas bubbling up from a lava-covered surface on the super-Earth exoplanet 55 Cancri e may feed an atmosphere rich in carbon dioxide or carbon monoxide,...
Goldene in the form of gold monolayer sheets has been prepared by etching away titanium carbide (Ti3C2) slabs from titanium gold carbide (Ti3AuC2).
Preparation...
