Sulfur-rich Mercury magmas behave differently than Earth’s do

by quasarn01 | Apr 19, 2026 | Astronomy

Mercury is a small, rocky planet about which researchers know relatively little. Two missions, taking readings as they passed over the planet, have revealed that Mercury is covered by an iron-poor and sulfur-rich crust. It is also reduced, a chemical state in which...

These blazing blue explosions may be born when a compact dead star slams into a Wolf-Rayet star

by quasarn01 | Apr 19, 2026 | Astronomy

Luminous fast blue optical transients (LFBOTs) are among the universe’s brightest and fastest explosions but their origin is not completely understood. A new study takes a closer look at the galaxies they occur in, offering two important clues about their...

Theoretical models of supernova chemistry overhauled after X-ray data from Perseus Cluster reveal key discrepancies

How tiny voids could make fusion targets more stable under powerful shockwaves

by quasarn01 | Apr 19, 2026 | Latest in Physics

Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that wave hits a bump in the material interface, it slows down. If it hits a...
