James Webb Space Telescope Detects Supernova From 11.4 Billion Years Ago
Astronomers using the James Webb Space Telescope (JWST) have identified AT 2023adsv, a supernova that occurred 11.4 billion years ago. This stellar explosion, from a star 20 times the size of the Sun, offers a glimpse into the early universe's unique stellar evolution. Part of the JWST Advanced Deep Extragalactic Survey, the event highlights how th...

Astronomers Spot New Cosmic Explosions 100 Times Brighter Than the Sun
Astronomers have discovered a new class of cosmic explosions, known as 'millinovas,' which are 100 times brighter than the Sun. These events, first identified in 2023, were observed in the Large and Small Magellanic Clouds, two satellite galaxies of the Milky Way. The millinovas are thought to occur when white dwarfs feed off a companion star, prod...

NASA's Parker Solar Probe Unveils New Insights into Solar Heating Mystery
NASA's Parker Solar Probe has delivered groundbreaking insights into one of the sun's most perplexing mysteries: why its outer atmosphere, or corona, is significantly hotter than its surface. This phenomenon, known as the "coronal heating mystery," has puzzled scientists for decades. The Parker Solar Probe, which is the fastest human-made object, h...

NASA Shares Photos Of Massive Explosions On Sun That Unleashed Solar Flares
NASA has recorded two explosions on the surface of the sun which unleashed powerful solar flares on Friday and Saturday.

Solar Flares Seen During Total Solar Eclipse. Here's What It Means
A solar flare is a massive explosion that occurs on the Sun when energy that has been trapped in "twisted" magnetic fields, which are often found above sunspots, is abruptly released.

NASA's Spacecraft Flies Through Most Powerful Solar Explosion Ever Recorded
NASA's Parker Solar Probe captures unprecedented footage of a massive solar eruption on a close approach to the Sun.

Largest Cosmic Explosion That Occurred 8 Billion Light Years Away Detected
Astronomers have discovered the largest cosmic explosion that has ever been witnessed. The event took place eight billion light years away from Earth and lasted for three years.

Hubble Telescope Reveals Huge Star's Explosion In Blow-By-Blow Detail
About 11.5 billion years ago, a distant star roughly 530 times larger than our sun died in a cataclysmic explosion that blew its outer layers of gas into the surrounding cosmos, a supernova documented by astronomers in blow-by-blow detail.

ESO Releases Image of Aftermath of Large Star's Explosive Death
The aftermath of a large star's explosive death is seen in an image released on Monday by the European Southern Observatory, showing immense filaments of brightly shining gas that was blasted into space during the supernova. Before exploding at the end of its life cycle, the star is believed to have had a mass at least eight times greater than our ...

NASA's First Set of Small Satellites for SunRISE Mission Ready to Detect, Track Hazardous Space Weather Events
The first of the small satellites to be used in NASA's SunRISE, or Sun Radio Interferometer Space Experiment, have been completed at Utah State University Space Dynamics Laboratory (SDL). The SDL has been contracted by the American space agency to build, test, and commission all six satellites for the mission to detect and track hazardous explosiv...

Chandra X-Ray Observatory Reveals Information on the Events Around a Rejected Star
Data received from the US space agency NASA's Chandra X-ray Observatory has revealed some fascinating features of a star, which was likely ejected from its birthplace due to a powerful explosion. The star, Zeta Ophiuchi, has a complicated past and is located some 440 light-years from Earth.

Dormant Black Hole Deemed ‘Needle in a Haystack’ Identified Outside the Milky Way
Astronomers have identified a black hole that not only is classified as dormant but appears to have been born without the explosion of a dying star, in a galaxy adjacent to the Milky Way. Black holes are extraordinarily dense objects with gravity so intense not even light can escape. Deemed a cosmic "needle in a haystack", the newly discovered ‘d...

Meet the 'Zombie Star', Residing in Spiral Galaxy NGC 1309, That Survived Supernova Blast
Astronomers have observed a star that not only survived a stellar explosion called a supernova, but emerged from it brighter than before the blast. This white dwarf is gravitationally locked in orbit with another star — a pairing called a binary system.

NASA Shares Stunning Image of Solar Flares Recently Ejected by Sun
The Sun's surface is marked by electrically charged gases that keep generating powerful magnetic forces. Their area of influence is called magnetic fields. As these gases are dynamic, they continuously stretch and twist the magnetic fields. Sometimes, this tangling of magnetic fields causes a sudden explosion of energy called solar flares.
