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.....»»
Check out this supercomputer’s stunning image of a supernova remnant
Australia’s newest supercomputer, Setonix, has crunched masses of data to create a stunning image of a supernova remnant......»»
NASA"s Fermi telescope confirms star wreck as source of extreme cosmic particles
Astronomers have long sought the launch sites for some of the highest-energy protons in our galaxy. Now a study using 12 years of data from NASA's Fermi Gamma-ray Space Telescope confirms that one supernova remnant is just such a place......»»
James Webb Space Telescope may have spotted its first supernova
The James Webb firsts keep coming, with the new space telescope having recently spotted its first supernova......»»
Balancing act: Can precariously perched boulders signal long-term earthquake risk?
The trouble with big earthquakes is that their subterranean root systems can lurk for centuries or millennia before building enough energy to explode. Among many places, this is true of the New York City area, where scientists believe big quakes are.....»»
Rewinding a supernova with machine learning
New work looks at using machine learning to decipher the early stages of supernovae explosions by reconstructing the light emitted during the outburst. The research was presented today at the 2022 National Astronomy Meeting by Eleonora Parrag, a Ph.D.....»»
The star that survived a supernova
A supernova is the catastrophic explosion of a star. Thermonuclear supernovae, in particular, signal the complete destruction of a white dwarf star, leaving nothing behind. At least that's what models and observations suggested......»»
Astronomers find evidence for most powerful pulsar in distant galaxy
Astronomers analyzing data from the VLA Sky Survey (VLASS) have discovered one of the youngest known neutron stars—the superdense remnant of a massive star that exploded as a supernova. Images from the National Science Foundation's Karl G. Jansky V.....»»
Cosmic "dust" from supernovae hints at how stars are born
New research detected strong polarization from a young supernova remnant. It provided independent and solid evidence that the cosmic dust in the early universe was formed in supernovae. While it's true that supernovae eject and destroy cosmic dust, i.....»»
Copper makes seed pods explode
Plants have evolved numerous strategies to spread their seeds widely. Some scatter their seeds to the wind, while others tempt animals and birds to eat their seed-filled fruits. And a few rare plants—such as the popping cress Cardamine hirsuta—ha.....»»
Mysterious Hypatia stone might hold earliest evidence of Type Ia supernova
Latest chemical "forensic" analysis finds telltale abundances of trace elements. Enlarge / Tiny samples of the Hypatia stone next to a small coin. Rare type Ia supernovas are some of the most energetic events in the universe. Researche.....»»
A dazzling Hubble collection of supernova host galaxies
Spanning from 2003 to 2021, this collection of images from the NASA/ESA Hubble Space Telescope features galaxies that are all hosts to both Cepheid variables and supernovae. These two celestial phenomena are both crucial tools used by astronomers to.....»»
Pixel smartphone sales explode by 220% in the UK
Thanks to the Google Pixel 6, it appears that Pixel sales in countries like the UK have seen an explosion in popularity. The post Pixel smartphone sales explode by 220% in the UK first appeared on Phandroid. Google’s Pixel smartphone.....»»
Extraterrestrial stone brings first supernova clues to Earth
New chemistry "forensics" indicate that the stone named Hypatia from the Egyptian desert could be the first tangible evidence found on Earth of a supernova type Ia explosion. These rare supernovas are some of the most energetic events in the universe.....»»
Hubble captures the beautiful aftermath of a supernova explosion
Supernovas might spell the end for the star they happen to, but they aren't only destructive. Hubble has captured a beautiful remnant created by a supernova......»»
Astronomers spot quadruple stars that may spark supernova explosions
A quadruple star system discovered in 2017 and recently observed at the University of Canterbury Mt. John Observatory could represent a new channel by which thermonuclear supernova explosions can occur in the universe, according to results published.....»»
Extremely resilient star survives a giant supernova explosion
This is a tale of survival.In the deep cosmos, the Hubble Space Telescope found evidence that a star remains after its companion star (they orbited each other) went supernova — an extremely powerful stellar explosion. The exploded star, dubbed.....»»
Watch eggs explode in extreme, art-like slow motion
The Slow Mo Guys are back with another artful masterpiece, this time letting eggs slowly explode into the air. As with most of their videos, you wouldn't expect the act to look so graceful but it ends up being exactly that, especially at the ridiculo.....»»
Hubble reveals surviving companion star in aftermath of supernova
NASA's Hubble Space Telescope has uncovered a witness at the scene of a star's explosive death: a companion star previously hidden in the glare of its partner's supernova. The discovery is a first for a particular type of supernova—one in which the.....»»
Simulating supernova remnants, star formation in earthbound lab
Molecular clouds are collections of gas and dust in space. When left alone, the clouds remain in their state of peaceful equilibrium......»»
Discovery of mysterious circular ring points to intergalactic origin
Western Sydney University researchers, together with an international team of experts, have discovered a mysterious circular ring near our neighboring galaxy that could be the first known case of an intergalactic supernova remnant—remains of an exp.....»»
