ANIMATION Radioactive molecules are sensitive to subtle nuclear phenomena and might help physicists probe the violation of the most fundamental symmetries of nature. Imagine a dust particle in a storm cloud, and you can get an idea of a neutron’s insignificance compared to the magnitude of the molecule it inhabits. […]

Illustration of a planet floating freely through the universe with a moon that can store water. Credit: © Tommaso Grassi / LMU The moons of planets that have no parent star can possess an atmosphere and retain liquid water. Astrophysicists at LMU have calculated that such systems could harbor sufficient […]

This illustration shows the distant Comet Bernardinelli-Bernstein as it might look in the outer Solar System. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times. It has an extremely elongated orbit, journeying inward from […]

An artist’s impression of two black holes about to collide and merge. Study offers evidence, based on gravitational waves, to show that the total area of a black hole’s event horizon can never decrease. There are certain rules that even the most extreme objects in the universe must obey. A […]

An artist’s depiction of a neutron star merger. These mergers produce heavy elements like gold and platinum in abundance. Credit: Sonoma State University/A. Simonnet Nucleosynthesis is the creation of new atomic nuclei, the centers of atoms that are made up of protons and neutrons. Nucleosynthesis first occurred within a few […]

Scientists at University of Chicago and University of California, Riverside have put forward a surprising theory to explain mysterious, supermassive black holes that formed early in the universe; those black holes could have formed with the help of dark matter.
