Although this spiral galaxy appears unremarkable from afar, NGC 7456 is bursting with newborn stars and glowing gas, providing researchers with insight into galactic evolution.
Read moreWhen two neutron stars collide, they unleash some of the most powerful forces in the universe, creating ripples in spacetime, showers of radiation, and even the building blocks of gold and platinum. Now, new simulations from Penn State and the University of Tennessee Knoxville reveal that elusive particles called neutrinos—able to shift between different “flavors”—play a crucial role in shaping what emerges from these cataclysmic events.
Read moreJezero Crater’s rocks reveal three stages of water activity, shifting from hostile acidic fluids to more life-friendly alkaline ones. Perseverance’s discoveries guide future sampling and strengthen the hunt for past life on Mars.
Read more'Weather' in clusters of galaxies may explain a longstanding puzzle. Scientists have now used sophisticated simulations to show how powerful jets from supermassive black holes are disrupted by the motion of hot gas and galaxies, preventing gas from cooling, which could otherwise form stars.
Read moreElectromagnetism was discovered 200 years ago, but the origin of the very large electromagnetic fields in the universe is still a mystery.
Read moreAstronomers have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they spotted a tiny dwarf galaxy in its very first, high-energy stages of star formation.
Read moreOut at the boundary of our solar system, pressure runs high. This pressure, the force plasma, magnetic fields and particles like ions, cosmic rays and electrons exert on one another when they flow and collide, was recently measured by scientists in totality for the first time — and it was found to be greater than expected.
Read moreA team of scientists have discovered that the fading of infrared light following Type Ia supernovae explosions can be interrupted, with brightness staying the same for up to a year.

A new visualization of a black hole illustrates how its gravity distorts our view, warping its surroundings as if viewed in a funhouse mirror.
