Astronomers have identified a rare stellar pair as the origin of long-period radio transients, mysterious repeating signals detected in the Milky Way. The system features a white dwarf drawing material from a red dwarf companion.

The James Webb Space Telescope has produced the most detailed infrared image yet of the Helix Nebula, showcasing a dying star shedding its outer layers. This close-up reveals glowing knots of gas shaped by stellar winds and highlights the nebula's role in recycling material for new stars and planets. Located 650 light-years away in Aquarius, the nebula offers insights into the potential future of our Sun.

A team using the CHARA Array at Georgia State University has produced high-resolution images of the early stages of two nova explosions detected in 2021. These images, created through near-infrared interferometry, reveal the rapidly evolving conditions right after the blasts. The findings indicate that the novae were not simple single events.

Observations from the James Webb Space Telescope suggest the presence of enormous stars in a distant early universe galaxy. These potential Population III stars could reach masses up to 10,000 times that of the sun. The findings may explain the origins of supermassive black holes.
