Scientsts from the United States, Europe and China have used the Ultraviolet Spectrograph (UVS) onboard NASA’s Juno spacecraft to map detailed patch...
Planetary scientists analyzing oxygen isotopes in lunar soil from the Apollo mission sites conclude that meteorite bombardment over 4 billion years could...
A team of researchers led by the University of Wisconsin-Madison has reverse-engineered a primordial nitrogen-fixing enzyme, illuminating how life thrived...
Researchers have found ancient gases and fluids trapped in 1.4-billion-year-old halite crystals from northern Ontario, Canada. Their analyses directly...
Scientists using the Ultraviolet Spectrograph (UVS) instrument aboard NASA’s Europa Clipper spacecraft have observed 3I/ATLAS, only the third confirmed...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered chemical fingerprints of primordial stars weighing between 1,000 and 10,000...
The atmosphere of Earth during the Mesozoic era, between 252 and 66 million years ago, contained far more carbon dioxide than it does today and total photosynthesis...
Around 390 million years ago (Devonian period), marine animals began colonizing depths previously uninhabited. New research led by scientists from Duke...
In a new paper, Penn State Professor Victor Pasko and his colleagues described how they determined strong electric fields in thunderclouds accelerate electrons...
Paleontologists have examined teeth of Teleoceras major — an extinct species of rhinocerotid that lived in North America from 17.5 to 5 million years...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected oxygen in the most distant confirmed galaxy ever found, JADES-GS-z14-0....
Described in a paper that appears today in the journal Nature Astronomy, the discovery means habitable exoplanets could have started forming much earlier...
A team of planetary researchers led by Caltech has determined the chemical mechanisms by which the ancient Mars was able to sustain enough warmth in its...
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...
In a paper published in the journal Nature Geoscience, scientists offer a new explanation for a string of severe environmental crises, called oceanic anoxic...
Until now, scientists broadly accepted complex life forms first emerged on Earth around 635 million years ago (Ediacaran period). But an international...
Researchers from the Scottish Association for Marine Science and colleagues have discovered that the polymetallic nodule-covered abyssal seafloor in the...
About 2.5 billion years ago, free oxygen first started to accumulate to meaningful levels in Earth’s atmosphere, setting the stage for the rise of complex...
