Exploding stars may have motivated human ancestors to walk

This is an artistic representation of ancient supernovae that bombarded Earth with cosmic energy millions of years ago. Galaxy NGC 4485 collided with its larger galactic neighbor NGC 4490 millions of years ago. Astronomers developed a mosaic of the distant universe called Hubble Legacy Field, which documents 16 years of Hubble Space Telescope observations. The image contains 200,000 galaxies spanning …

How hot are atoms in the shockwave of an exploding star?

An international team of researchers combined observations of the nearby supernova SN1987A, created with NASA's Chandra X-ray Observatory, with simulations to measure the temperature in shock waves produced by the explosive death of a star. This image overlays synthetic X-ray data on a density map with the simulation of SN1987A. Photo credits: Marco Miceli, Dipartimento di Fisica and Chimica, Università …
