Did this supernova explode twice?
All supernovae are exploding stars. But the nature of a supernova explosion varies quite a bit. One type, named Type 1a supernovae, involves a binary star where one of the pair is a white dwarf. And while supernovae of all types usually involve a sin.....»»

Astrophysicists determine how to find a supernova
The probability of detecting a supernova associated with a gamma-ray burst is currently 0.00346%. A network of several telescopes in different geographical coordinates, checking data in different photometric filters, analyzing images and taking into.....»»
Ascertaining distances for supernovae that struck the Earth 3 million and 7 million years ago
A study, released on the pre-print server arXiv, examines how the Earth was hit by blasts from supernovae (plural form of supernova (SN)) that occurred 3 million years ago (Mya) and 7 Mya with the goal of ascertaining the distances of where these bla.....»»
Observations explore the properties of Type Ic supernova SN 2022jli
An international team of astronomers has performed multi-wavelength photometric and spectroscopic observations of a recently discovered Type Ic supernova known as SN 2022jli. Results of the observational campaign, published September 22 on the pre-pr.....»»

Saturday Citations: Volcano vs. asteroid; NASA"s supernova time lapse; immortal chemicals
This week, we're highlighting a study involving toxic chemical contaminants, and just for fun, a second study involving other toxic chemical contaminants. But NASA made a cool time-lapse video using the good old Hubble space telescope, and a group of.....»»
Living on the edge: Supernova bubble expands in new Hubble time-lapse movie
Though a doomed star exploded some 20,000 years ago, its tattered remnants continue racing into space at breakneck speeds—and NASA's Hubble Space Telescope has caught the action......»»
Extreme weight loss: Star sheds unexpected amounts of mass just before going supernova
A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers insight into what happe.....»»
New Type I supernova discovered with JWST
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed the galaxy cluster PLCK G165.7+67.0. The observational campaign resulted in the detection of a new Type I supernova. The finding is reported in a paper pub.....»»
