Figure 1. A schematic illustration of the first star’s supernovae and observed spectra of extremely metal-poor stars. Ejecta from the supernovae enrich pristine hydrogen and…
Many chemical elements are formed during a supernova explosion, so studying them can give scientists insight into the universe’s chemical make-up. New research sheds light…

The new work extends models from nuclear physics. A new model for matter in neutron star collisions. After a massive star burns its fuel and…
An artist’s rendition of a red supergiant star transitioning into a Type II supernova, emitting a violent eruption of radiation and gas on its dying…
Artist’s illustration of cosmic ray-driven winds (blue and green) superimposed on a visible-light image of the Triangulum galaxy M33 (red and white) observed with VLT…
This image shows a spectacular view of the orange and pink clouds that make up what remains after the explosive death of a massive star…
This artist’s impression shows a field of Population III stars as they would have appeared a mere 100 million years after the Big Bang. Astronomers…
Astronomers think GRB 221009A represents the birth of a new black hole formed within the heart of a collapsing star. In this illustration, the black…

[unable to retrieve full-text content] A Tenacious Star Validates a Revised Model of Supernovae A supernova is the cataclysmic explosion of a star. Thermonuclear supernovae,…
Scientists from the RIKEN Cluster for Pioneering Research have used computer modeling to show how a hypothesized type of supernova would evolve on the scale…
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…
When a star explodes in a supernova, it sometimes leaves a remnant that has a ring shape, such as seen here in this illustration of…
The supernova known as 2014C took place eight years ago—but scientists are still watching and learning from its aftermath. The very faintly visible explosion is…
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…
This schematic shows the various ejecta and winds (red and purple) given off by the exploding star (left, yellow). The common-envelope disk (blue) surrounds both…
The fast shockwaves form an hourglass shape as they expand, in which gamma rays are produced. This gamma-ray emission is then detected by the H.E.S.S.…
An artist’s conception illustrates the aftermath of a “kilonova,” a powerful event that happens when two neutron stars merge. Credit: X-ray: NASA/CXC/Northwestern Univ./A. Hajela et…
