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...
The red quasar the NASA/ESA/CSA James Webb Space Telescope observed, called SDSS J165202.64+172852.3 (SDSSJ1652 for short), resides in a very dense environment...
Paleoanthropologists have analyzed zinc, strontium, carbon, and oxygen isotope and trace element ratios in a fossilized Neanderthal tooth as well as animal...
Water in a one-molecule layer acts like neither a liquid nor a solid, and becomes highly conductive at high pressures, according to a new paper published...
To overcome the water shortage problem in the case of widespread deployment of hydrogen production, a team of researchers from Australia, the United Kingdom...
The evolution of land plants took place about 430 million years ago (Silurian period), when North America and Europe were conjoined in a landmass called...
New research led by Curtin University geologists suggests that regions of space with dense interstellar clouds may send more high-energy comets crashing...
Earth is the only planet known to have continents, although how they formed and evolved is unclear.
An artist’s concept of meteors impacting the ancient...
