Scientists have set a new world record for high-temperature plasma, reaching ion temperatures of 100 million degrees Celsius (180 million degrees Fahrenheit) for a 20-second period with a Korea Superconducting TalkMac Advanced Research (KSTAR) device. Known as Korea’s “artificial sun”, KSTAR uses magnetic fields to generate and stabilize ultra-hot plasma …

At the end of the Universe, long after the last shining stars flickered, there could be one last explosion. Named black dwarf supernovae, these dazzling explosions will announce in the eternal darkness as the Universe falls asleep, a new study suggests. These newly proposed supernovae are a special race that …

A rare fusion between clusters of galaxies has just revealed an even rarer face. Astronomers have found a large, low-frequency radio ‘bridge’ between the two, spanning a distance of 6.5 million light-years – evidence of a magnetic field that connects them in the early stages of the merging process. It …
