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...
To gather information on the animals’ habits, University of British Columbia’s Professor Andrew Trites and his colleagues used drone footage and biological...
An ultra-weak geomagnetic field between 591 and 565 million years ago (Ediacaran period) coincided with a significant increase in the oxygen levels in...
In May 2017, NASA’s Curiosity rover observed higher than usual amounts of manganese in the lakebed rocks within Gale crater, Mars. These sedimentary...
NGC 6440 is a typical massive, obscured and contaminated globular cluster formed and orbiting within the bulge of our Milky Way Galaxy.
This Webb image...
In August 2021, the ESA/JAXA Mercury-bound BepiColombo spacecraft performed its second flyby of Venus and provided a short-lived observation of its induced...
Using data from the Jovian Auroral Distributions Experiment (JADE) instrument onboard NASA’s Juno spacecraft, planetary scientists have calculated the...
The earliest known evidence of photosynthetic structures has been identified inside a collection of the enigmatic cylindrical microfossils Navifusa majensis...
