‘Once-in-a-lifetime’ nova explosion will bring a new star to the night sky, NASA says

Astronomers expect a “new star” to appear in the night sky between now and September in a celestial event that has been in the works for years, according to NASA. “It is a once-in-a-lifetime event that will create many new astronomers, giving young people a cosmic event that they can observe for themselves, ask their … Read more

A star that exploded like an atomic bomb still raises questions half a century later

a galactic disc of gas sucks the light off a closer red star.

The aftermath of a thermonuclear explosion in a double star system about 3,400 light-years away has been observed by the Hubble Space Telescope. HM Sagittae, or simply HM Sge, is a so-called symbiotic system, in which a white dwarf feeds on a companion red giant star. The stolen material forms an accretion disk that swirls … Read more

‘Supernova discovery machine’ James Webb Space Telescope finds the most distant star explosion ever recorded

Red and yellow dots against a black ground with some circled with blue rings

When it comes to hunting down the explosive deaths of massive stars in the early universe, the James Webb Space Telescope (JWST) is a true cosmic detective. This celestial Sherlock Holmes has found evidence of 80 new early supernovae in a patch of sky as wide as a grain of rice, held at arm’s length. … Read more

Webb telescope discovers a mysterious carbon treasure around the young star

SciTechDaily

This is an artist’s impression of a young star surrounded by a disk of gas and dust. An international team of astronomers used NASA’s James Webb Space Telescope to study the disk around a young, very low-mass star known as ISO-ChaI 147. The results reveal the richest hydrocarbon chemistry yet observed in a protoplanetary disk. … Read more
