Sample of Hypatia Stone From Outside Solar System

Extraterrestrial Stone Could Be First Evidence on Earth of Supernova Ia Explosion

A 3-gram (0.1 ounce) sample of the Hypatia stone. Researchers found a consistent pattern of 15 elements in the Hypatia stone. The pattern is completely unlike anything in our solar system or our solar neighborhood, in the Milky Way. Credit: Romano Serra New chemistry ‘forensics’ indicates that the stone named Hypatia from the Egyptian desert …

Astronomers Witness The X-Ray 'Fireball' of a Stellar Nova For The First Time

Astronomers Witness The X-Ray ‘Fireball’ of a Stellar Nova For The First Time

The brief, yet colossal eruption of a dead star undergoing a nova explosion has been captured by one of the most powerful X-ray instruments in space. The joint German-Russian eROSITA telescope, aboard the Spektr-RG space observatory in the L2 Lagrange point (yes, Webb’s home), caught for the first time what is known as the ‘fireball’ …

Hubble Reveals Surviving Companion Star in Aftermath of Titanic Supernova Explosion

Hubble Reveals Surviving Companion Star in Aftermath of Titanic Supernova Explosion

This artist’s illustration shows supernova 2013ge, with its companion star at the lower right. The companion star is impacted by the blast wave from the supernova, but not destroyed. Over time astronomers observed the ultraviolet (UV) light of the supernova fading, revealing a nearby second source of UV light that maintained brightness. The theory is …
