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...
Planets too close to their star are too hot (such as Venus), those too far, are too cold (like Mars), whereas planets in the habitable zone are just right....
The atmospheric nightglow is observed on Earth. On Mars, it was something expected, yet never observed in visible light until now.
This image shows an...
Atomic oxygen is produced on the dayside of Venus by photolysis of carbon dioxide and carbon monoxide.
Atomic oxygen is a key species in the mesosphere...
In the search for life in the Universe, Earth provides a template of evolution for the one habitable planet we know. Earth’s atmospheric composition...
The oxygen-28 (28O) nucleus is of particular interest as, with the Z = 8 (protons) and N = 20 (neutrons) magic numbers, it is expected in the standard...
Active galactic nuclei are primarily powered by a supermassive black hole lying at the center of a host galaxy that is accreting matter from its vicinity....
Jupiter’s moon Ganymede is the only satellite in the Solar System known to have an intrinsic magnetic field. Interactions between this field and the...
