ZTF discovers a new mass-transferring brown dwarf binary system
Astronomers from the California Institute of Technology (Caltech) and elsewhere report the discovery of a binary system consisting of two brown dwarfs undergoing stable mass transfer. The detection of the system, designated ...
TESS discovers an Earth-sized planet orbiting nearby M-dwarf star
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an extrasolar planet orbiting TOI-4616—a nearby M-dwarf star. The newfound alien world, which received designation ...
Black hole mergers test the limits of general relativity
General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from rotational frame dragging ...

The JWST finds more overmassive black holes. This time in dwarf galaxies
One of the things astronomers find when they look around at galaxies is a correlation between a galaxy's mass and the mass of its supermassive black hole. Contrary to popular belief, these SMBH don't anchor their galaxies; ...

Giant craters may reveal if Psyche is a lost planetary core
When we think of asteroids, we almost immediately think of giant rocks bouncing around like the iconic chase scene in "The Empire Strikes Back," and we often hear how they are remnants from the birth of the solar system. ...

Scientists detect magnetic waves deep within the sun, helping predict solar activity
Researchers at NYU Abu Dhabi have discovered new large-scale waves moving deep inside the sun, driven by magnetic fields far below the surface. These waves provide a window into parts of the sun that are otherwise inaccessible, ...

Earth's magnetic field creates a previously undetected pocket of protection from radiation on the moon
High-energy particles called galactic cosmic rays (GCRs) bombard unprotected objects in space, often causing damage. Earth, however, is protected by its magnetic field, which creates a protective shell around the planet that ...
Human sperm may get lost in space
