A supernova and its host galaxy are the subject of this NASA/ESA Hubble Space Telescope image. The galaxy in question is LEDA 132905 in the constellation

Explosions shouldn't get brighter after they fade...right?

The subject of this NASA/ESA Hubble Space Telescope image is a supernova-hosting galaxy located about 600 million light-years away in the constellation

This NASA/ESA Hubble Space Telescope image features the galaxy LEDA 857074, located in the constellation Eridanus. LEDA 857074 is a barred spiral galaxy, with partially broken spiral arms. The image also captured a supernova, named SN 2022ADQZ, shining brightly on the right side of the galaxy's bar.

In the latest issue of the journal Nature, astronomers from Stockholm University reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the exploding white dwarf star had a helium-rich companion.

An international group of astronomers has used observations to unlock a puzzling mystery about a stellar explosion discovered several years ago and evolving even now. The results will help astronomers better understand the process of how massive stars live and die.

Introduction In the lasts posts we've been writing about proving systems and incremental verifiable computation: * Pinocchio Virtual Machine: Nearly Practical Verifiable Computation * Decentralized private computation: ZEXE and VERI-ZEXE * Incrementally verifiable computation: NOVA Incremental proof systems offer some advantages over conventional proving systems: * They do not require static bounds on loop…

The tattered shell of the first-ever historically recorded supernova was captured by the US Department of Energy-fabricated Dark Energy Camera, which is mounted on the National Science Foundation's (NSF) Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF's NOIRLab. RCW 86's ring of debris is all that remains of a white-dwarf star that exploded more than 1800…

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have begun the study of SNR 1987A, one of the most renowned supernova remnants.

Fireworks display from rare dying star is unlike anything astronomers have seen

Filipp Romanov discovered a supernova on February 20, 2022, using the remote iTelescope T24 in California. It's his first confirmed supernova discovery. The post Supernova discovery by EarthSky Community member first appeared on EarthSky.

NASA has released a beautiful photo taken by the NASA/ESA Hubble Space Telescope of the spiral galaxy LEDA 22057.

This NASA/ESA Hubble Space Telescope image features the galaxy LEDA 857074, located in the constellation Eridanus. LEDA 857074 is a barred spiral galaxy, with partially broken spiral arms. The image also captured a supernova, named SN 2022ADQZ, shining brightly on the right side of the galaxy's bar. Several evolutionary paths can lead to a supernova […]

Pierrick's and his son's passion for dirt-track racing leads to some friendly competition, in a short documentary by Damien and Marc Bettinelli.

In a recent Webb telescope image, astronomers simultaneously captured three moments during an ancient supernova explosion marking the death of a star.

New work looks at using machine learning to decipher the early stages of supernovae explosions by reconstructing the light emitted during the outburst. The research was presented today at the 2022 National Astronomy Meeting by Eleonora Parrag, a Ph.D. student at the University of Cardiff.

A strange supernova remnant first appeared as a "guest star" seen in 1181 by sky watchers in China and Japan
