Faint Companion Star Likely Found Orbiting Betelgeuse
Researchers using the Gemini-North telescope and speckle interferometry have likely detected a faint stellar companion to Betelgeuse, a red supergiant star in Orion, solving a long-standing mystery about its brightness fluctuations; the companion, estimated at 1.6 solar masses, is predicted to be co...

Gold's Origin: Core-Collapse Supernovae
Core-collapse supernovae, resulting from the implosion of massive stars, produce gold within hours via shockwaves that synthesize heavy elements through photodisintegration and neutron formation.

Supernovas May Have Caused Two Unexplained Mass Extinctions on Earth
A new study hypothesizes that two of Earth's largest mass extinctions, the Late Devonian (372 million years ago) and Late Ordovician (445 million years ago), might have been caused by nearby supernovas, suggesting that supernova radiation could have damaged the ozone layer, leading to a chain of eve...

Supernovas May Have Caused Two of Earth's Mass Extinctions
New research hypothesizes that nearby supernovas, occurring approximately every 500 million years based on calculations from the Gaia space telescope, may have caused the Late Ordovician and Late Devonian mass extinctions by damaging Earth's ozone layer, though direct evidence is lacking.

First Photographic Evidence of Type Ia Supernova's Double Detonation
Astronomers using the European Southern Observatory's Very Large Telescope have obtained the first photographic evidence of a Type Ia supernova, a double-detonation event 160,000 light-years away in the Large Magellanic Cloud, revealing two concentric calcium shells expanding outwards, confirming th...

Mysterious Astronomical Explosions Suggest Existence of Intermediate-Mass Black Holes
Astronomers have observed approximately a dozen unusual bright, fast explosions, initially thought to be failed supernovae, but now theorized to be caused by intermediate-mass black holes consuming nearby stars, a discovery that could bridge the gap in black hole size understanding.

Supernovae Linked to Two Mass Extinction Events
A study suggests that two of Earth's five mass extinction events may have been caused by nearby supernovae, occurring roughly every 400 million years, based on an analysis of OB stars and the timing of ozone depletion events.
