Breakthrough discovery provides new clues about how these celestial bodies - that push the known laws of physics to their limits - find each other.

University of Cincinnati engineers looked for simple but effective ways to maintain a robot's orientation while working on a broken satellite in zero gravity. They discovered that a second robotic arm acting as a counterbalance could help the robot maintain stability.

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known as GRB 230906A, was likely caused by the collision of two neutron stars hundreds of millions of years ago and is now shedding light on how the universe creates some of its heaviest elements.  

Developed from recent observations, the model can be used to study exoplanets.

Three years ago, in the waters of the Mediterranean Sea, the passage of an “ultra-energetic” cosmic neutrino was observed — the most energetic ever detected. The event drew international attention from the scientific community as well as from the media and the public, not least because the origin of this particle — whose energy exceeded that of previously observed neutrinos by more than an order of magnitude — is unknown. A new paper published in the Journal of Cosmology and Astroparticle Physics (JCAP) by the KM3NeT collaboration, which operates the KM3NeT/ARCA detector off the coast of Sicily, suggests that the source of this particle may be in a population of blazars — active galactic nuclei hosting a supermassive black hole that emit a plasma jet directed toward Earth.
