The infographic illustrates SN 2021ukt, a groundbreaking supernova that underwent a first-of-its-kind identity transition. Initially a Type IIn, it transformed into a Type Ib as its ejecta interacted with a dense hydrogen cloud. This significant shift marks a new understanding in supernova classification, emphasizing the unique nature of the progenitor star and its hydrogen envelope.
The Vera Rubin Observatory will do more than probe dark energy—it is poised to revolutionize our detection of Near-Earth Objects, giving us unprecedented warning before they strike.
The Vera Rubin Observatory (VRO) has barely begun observations and is already wowing us. Images like its Cosmic Treasure Chest have us anticipating even more cosmic glory. And when the observatory sent out 800,000 alerts in one night in February, we got a taste of the scientific boost it will giv
Just a few days in simulated microgravity can subtly change the way women's blood clots, sparking bigger questions about health monitoring protocols for astronauts who spend six months or more in orbit.
First reported in 2020, an International Space Station (ISS) mission detected an unexpected blood clot in a female astronaut's jugular vein.
For the first time, scientists have successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec within the gamma-ray halo surrounding the Geminga pulsar wind nebula.
Published in Science Advances, this groundbreaking observation extends to the highest energies—above 100 tera-electron volts (TeV)—providing entirely new insights into the behavior of cosmic rays and magnetic fields within the Milky Way.
