X-ray radiation from black holes explained

Monday, August 26, 2024 by Freeman Lightner

Using detailed supercomputer simulations, researchers at the University of Helsinki modeled the interactions between radiation, plasma, and magnetic fields around black holes. It was found that the chaotic movements, or turbulence, caused by the magnetic fields heat the local plasma and make it radiate. Focus on the X-ray radiation from accretion disks A black hol...

Mars InSight lander reveals crust could have stores of liquid water

Wednesday, August 21, 2024 by Freeman Lightner

The recent analysis of data from the Mars InSight lander suggests that the presence of liquid water in the Martian crust is the most plausible explanation for the observed findings. This conclusion, led by Vashan Wright, a geophysicist at UC San Diego’s Scripps Institution of Oceanography, provides the strongest evidence yet that liquid water exists on Mars, in ad...

UH astronomers reveal that red dwarf stars can produce stellar flares

Thursday, August 8, 2024 by Russ Scritchfield

A groundbreaking study has revealed that red dwarf stars can produce stellar flares that carry far-ultraviolet (far-UV) radiation levels much higher than previously believed. This discovery suggests that the intense UV radiation from these flares could significantly impact whether planets around red dwarf stars can be habitable. Led by current and former astronomers fro...
