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...
Boron monoxide, a binary compound of boron and oxygen, was first reported in the 1940s. However, scientists were unable to determine the structure of the...
Superradiance occurs when an atomic nucleus reaches a high excitation energy.
Mirror nuclei, such as oxygen-18 and neon-18, have the same number of protons...
In new research, scientists from the University of Cambridge and elsewhere reconstructed changes in summer and winter rainfall from trace elements and...
The dinosaur-bird transition is among the most fascinating events in evolutionary history, but several aspects such as changes in reproductive system,...
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...
GHZ2/GLASS-z12, initially identified in the JWST GLASS survey, existed when the Universe was only 367 million years old (redshift z=12.117).

While the NASA/ESA/CSA James Webb Space Telescope and other space telescopes previously have revealed isolated ingredients of the atmosphere of WASP-39b,...
The Devonian period, which occurred 419 to 358 million years ago, prior to the evolution of life on land, is known for a series of catastrophic mass extinction...
Mass extinctions are well recognized as significant steps in the evolutionary trajectory of life on Earth. In new research, geobiologists from Virginia...
