NASA's Fermi mission sees no gamma rays from nearby supernova

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray ...

Study uses thermodynamics to describe expansion of the universe

The idea that the universe is expanding dates from almost a century ago. It was first put forward by Belgian cosmologist Georges Lemaître (1894–1966) in 1927 and confirmed observationally by American astronomer Edwin Hubble ...

Study presents evidence that recent reductions in aerosol emissions create an additional warming effect

Recent reductions in emissions of tiny particles, the major cause of air pollution globally, have led to more heat in the Earth's climate system. This is shown in a new international study led by CICERO and published in Communications ...

New research traces the fates of stars living near the Milky Way's central black hole

Despite their ancient ages, some stars orbiting the Milky Way's central supermassive black hole appear deceptively youthful. But unlike humans, who might appear rejuvenated from a fresh round of collagen injections, these ...
