Alien stone discovered in Egypt may be Earth’s first evidence of rare supernova
“Standard candle” (or Type Ia) supernova explosions are among the most energetic events in the Universe, occurring when a dense white dwarf subsumes another star. Now scientists believe they have found the first evidence on Earth of such a supernova. The claim comes after careful study of the alien stone Hypatia which was found in […]

This Record-Breaking “Gold Standard” Star Is Unlike Any We’ve Seen Before
What’s in a star? Well, if you’re a highly evolved specimen nearing the end of its life named HD 222925, that’s quite a lot, actually. Scientists conducted an analysis of this dark object and identified 65 distinct elements. This is the largest number of elements ever found in a single object outside the solar system, […]

Astronomers witness the X-ray ‘fireball’ of a stellar nova for the first time
The brief but colossal flare 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 at Lagrange Point L2 (yes, Webb’s home), captured the so-called “fireball” phase for the first time. “of a classic […]
