An analysis of Northwest Africa (NWA) 16286, a lunar meteorite with a unique chemical signature, offers fresh insights into how the Moon’s interior evolved,...
There is extensive geologic evidence of ancient volcanic activity on the Moon, but it is unclear how long that volcanism persisted. Magma fountains produce...
The rapid neutron capture process, or the so-called r-process, occurs in neutron-rich environments such as neutron star mergers or certain types of supernovae....
By analyzing tiny lunar zircon crystals gathered by Apollo 17 astronauts in 1972, planetary scientists recalculated the age of the Moon. Although previous...
Harvard University’s Professor Avi Loeb and colleagues have discovered at least 50 tiny spherical iron fragments near the fireball path of the first...
An explosion of a fast-spinning strongly magnetized star, called a magneto-rotational hypernova, is the most likely explanation for the presence of unusually...
Physicists at the Heavy Ion Research Facility in China have observed the lightest uranium isotope to date, uranium-214 (214U), and precisely measured the...
The thermal evolution of rocky planets depends on the heat input from three long-lived radiogenic elements: potassium, thorium, and uranium. Concentrations...
An international team of physicists has used high-resolution microscopy tools to peer at the inner-workings of the recently-discovered heavy-fermion superconductor,...
An underground particle detector called the Borexino detector has detected 53 antielectron neutrinos emanating from the Earth, so-called geoneutrinos.
The...
Physicists have observed a rare phenomenon called re-entrant superconductivity in uranium ditelluride (UTe2). The discovery, reported in the journal Nature...
According to new research, a nearby binary neutron-star merger gave birth to 0.3% of the Earth’s heaviest elements, including gold, platinum and uranium;...
In conventional magnets, small magnetic constituents align with one another to create a strong magnetic field. By contrast, the newly-discovered type of...
Origin of Universe’s heavy elements, ranging from gold to uranium, has finally been confirmed, after a gravitational wave source was seen and heard for...
A new study published in the Astrophysical Journal Letters examines whether radioactive decay could support life on ocean worlds like Jupiter’s moon...
