The incredible story told by a supernova remnant

Astrophysical archaeology helps us learn the history of stars, revealing events like supernovae that impact our understanding of space and time.

How a nearby supernova could reveal dark matter

Dark matter's existence is inferred indirectly; direct detections have yielded null results, highlighting a need for extreme cosmic conditions.

The mystery of the Milky Way's most bizarre supernova

There are two primary pathways for supernovae: massive star core collapse and white dwarf explosions through mergers.

Daily briefing: 'All of Us' genetics chart stirs unease

The debate on depicting human diversity in genetics has been reignited by a figure in a high-profile paper.
A supernova mystery from 1987 has been solved, confirming it as a neutron star.

The Webb Telescope Just Solved a 37-Year-Old Space Explosion Mystery

SN 1987a resulted in a neutron star, not a black hole.
Scientists used data from the JWST to confirm the presence of the neutron star in SN 1987a.

Behold, the Mind-Blowing Bubbles of Betelgeuse

Betelgeuse is a red supergiant with unusual surface activity causing observable variations in its brightness.
Betelgeuse's high spin rate might be an illusion created by its large size and surface activity.

Daily Telescope: Finally, we've found the core of a famous supernova

SN 1987A, the first observable supernova, still a topic of study
James Webb Space Telescope finds emission lines from a newly born neutron star

Astrophysicists Solve Mystery of 12th-century Supernova - Medievalists.net

SN 1181 is a supernova documented by ancient astronomers, notable for its long visibility and implications for understanding stellar explosions.

Astronomers have found leftover 'zombie star' from supernova shone in the night sky 1,000 years ago

A rare Type Iax supernova event occurred in 1181, likely caused by a collision of two white dwarfs, leaving behind a 'zombie star.'

Saturday Citations: Citizen scientists observe fast thing; controlling rat populations; clearing nanoplastic from water

Discovery of CWISE J124909+362116.0, the first low-mass hypervelocity star, suggests a link to a white dwarf supernova event.

If Betelgeuse Explodes, Just How Bright Will It Get?

Betelgeuse, a famous star in the Orion constellation, is a red supergiant that has dimmed recently, potentially hinting at an impending supernova event in the future.

A new origin story for supernovae after 94 years

Stars can supernova through different pathways; massive stars via core collapse and less massive stars via white dwarf detonation.
Recent research suggests the older model for type Ia supernovae is inadequate, prompting a focus on more complex scenarios.

NASA's latest supernova image could tell us how fast the universe is expanding

The James Webb Space Telescope captured a unique image of a supernova that helps in understanding the expansion of the universe.

Full Flower Moon will appear in sky this week near supergiant star

The Flower Moon shines during a significant celestial event.

Don't PanicAt Least, Not about a Nearby Supernova

A nearby supernova's power is incomprehensible, releasing energy millions of times the sun's luminosity, impacting Earth even from great distances.

Behold the Strange Beauty of A Tangled Nebula

The Spaghetti Nebula is debris from a cosmic explosion, visible 40,000 years ago.
The filaments are made of hydrogen and oxygen, remnants of a massive star's explosion.

Astronomers Captured A Supposedly Dead Star Feasting On Its Cosmic Neighbor

Observations of a supernova in galaxy NGC 157 revealed a dead star flashing at regular intervals as it dimmed.
Bursts of movement of hydrogen gas coincided with the flashing bursts of light and powerful bursts of gamma rays.

Betelgeuse Will Briefly Disappear in Once-in-a-Lifetime Coincidence

Sky watchers will witness Betelgeuse briefly disappear as an asteroid blocks its view.
Scientists hope to use this opportunity to observe Betelgeuse's surface in high resolution.

A Supernova Blew Out Part of Earth's Atmosphere, Scientists Say

A powerful supernova 1.9 billion light-years away caused a gamma ray burst (GRB) known as the BOAT, with scientists estimating such an event occurs once in every 10,000 years.
The BOAT GRB took a chunk out of Earth's upper atmosphere, temporarily destroying the ozone layer, but it repaired itself in minutes.
GRBs in our own galaxy could potentially wipe out Earth's ozone layer for years, causing a devastating extinction event.

A Supernova Destroyed' Some of Earth's Ozone for a Few Minutes in 2022

Astronomers have discovered that a supernova explosion 1.9 billion light-years away caused a temporary depletion of ozone in Earth's upper atmosphere.
The gamma ray burst from the supernova resulted in a measurable change in the number of ionized particles in the atmosphere, including ozone molecules.
While the effect was only detectable for a few minutes and the ozone repaired itself, a closer supernova explosion could have catastrophic consequences for Earth's ozone layer.
