UGC 5189A, a relatively small galaxy located about 150 million light-years from Earth is featured in the Hubble Space Telescope image. Credit: ESA/Hubble & NASA,…
Astronomers discovered enormous radio wave circles in 2019, named ORCs. Research led by Professor Alison Coil indicates these are caused by galactic winds from starburst…
Groundbreaking observations by a Cornell-led team reveal repeated energetic flares from a stellar corpse following a star’s explosion, challenging existing theories about stellar deaths and…
This deep dataset from Chandra of the remains of a supernova known as 30 Doradus B (30 Dor B) reveals evidence for more than one…
This artist’s impression shows how hot, brilliant and high-mass stars evolve. The more massive brighter star expands first, until the outer layers start to strongly…
This new image of supernova remnant SN 1006 combines data from NASA’s Imaging X-ray Polarimetry Explorer and NASA’s Chandra X-ray Observatory. The red, green, and…
Visualization of a binary star experiencing mass transfer. Credit: © Ylva Götberg Uncovering the missing precursors of hydrogen-poor supernovae. Supernovae–stellar explosions as bright as an…
University of Tokyo researchers have applied deep learning to supernova simulations, significantly improving accuracy and efficiency, with potential applications in astrophysics and beyond, including climate…
This new image of supernova remnant SN 1006 combines data from NASA’s Imaging X-ray Polarimetry Explorer and NASA’s Chandra X-ray Observatory. The red, green, and…
A new study using nearly eight years of data from the CALorimetric Electron Telescope (CALET) instrument on the International Space Station reports more electrons arriving…
ESA’s Integral space telescope detected an unprecedented gamma-ray burst from a distant exploding star, causing significant disturbances in Earth’s ionosphere. This event, the brightest and…
This image taken by NASA’s Hubble Space Telescope shows part of the Veil Nebula or Cygnus Loop. To create this colorful image, observations were taken…
In the year prior to going supernova the red supergiant star now known as SN 2023ixf shed an unexpected amount of mass equivalent to the…
The three-dimensional simulation of the exotic supernova reveals the turbulent structures generated during the material ejection in the explosion. These turbulent structures subsequently impact the…
Animation showing the formation of a supernova remnant. New research, which will utilize advanced telescopes and blend machine learning with manual observation, hopes to double…
Ejecta from the first supernovae (cyan, green, and purple objects surrounded by clouds of ejected material) enrich the primordial hydrogen and helium gas with heavy…
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…
Artist’s impression of two white dwarf stars merging and creating a Type Ia supernova. Credit: ESO/L. Calçada What Is a Supernova? Supernovae are dramatic explosions…
