Stars - NASA Science

Stars form in molecular clouds, eventually leading to protostars and stellar clusters.
Main sequence stars undergo nuclear fusion, with gradual changes throughout their lifecycle.
The supernova explosion marks the death of a star, leaving behind dense remnants.

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

First Close Up Picture of Star Outside Our Galaxy Shows a Giant About to Blow

Astronomers have captured the first close-up image of a star, WOH G64, in another galaxy, revealing it as a dying red supergiant.

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.

First close-up image of a star outside Milky Way shows supergiant in cocoon'

Astronomers captured detailed images of WOH G64, revealing its egg-shaped cocoon and suggesting it is approaching a supernova phase.

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.'

This is what we'll see when Betelgeuse goes supernova

Betelgeuse is experiencing unprecedented brightness variations, indicative of unusual stellar activity.

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.

The first magnified photo of a dying star outside our galaxy indicates a violent end

Astronomers have captured the first high-resolution image of a dying red supergiant, WOH G64, indicating it's close to becoming a supernova.

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.

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.
