How Supernovae Explode: New Model Reveals Star Instability Before Massive Outburst

How and why do supernovae explode? Those are questions that astronomers have been attempting to answer for years--with only some success. Now, though, scientists have created a new model of supernovae that may just answer these questions.

The Prescription of a Cosmic, Gravitational Lens: Exploding Stars Shed Light on Lenses

The NASA Hubble Space Telescope has captured the images of three distant exploding stars with help of a gravitational lens. The latest pictures of the supernovae offer researchers a powerful tool to check the prescription of these gravitational lenses.

New Supernova Revealed with Gravitational Lens in Cosmic Illusion

Astronomers have made a startling discovery. They've found a galaxy that magnified a background, Type Ia supernova by 30 times through gravitational lensing.

Stellar Explosion Simulated: Key Supernova Phase Rendered at High Resolution

The supernovae that Chris Malone studies, Type Ia, are “basically thermonuclear explosions of really compact stars,” says the University of California, Santa Cruz, US, postdoctoral researcher. Malone and the other members of the astrophysics team, led by professor Stan Woosley, use computationa...

Starbursting in the Galaxy M82

Messier 82, the galaxy in which the nearest supernova in decades recently exploded, also is the closest galaxy that is undergoing a rapid burst of star formation, known as a starburst.

ALMA Telescope Spots Supernova Dust Factory

Astronomers have spotted the remains of a recent supernova brimming with freshly formed dust with the help of the Atacama Large Millimeter/submillimeter Array (ALMA) telescope. The findings could help explain how many galaxies acquired their dusty, dusky appearance.

New 2013 Supernova as Seen by Hubble Telescope

Supernovae are intensely bright objects. They are formed when a star reaches the end of its life with a dramatic explosion, expelling most of its material out into space.

Surprisingly Early Cosmic 'Seeding' of Life's Elements Driven by Supernovae and Blackholes

Most of the universe's heavy elements, including the iron central to life itself, formed surprisingly early in cosmic history and somehow spread evenly throughout the universe, according to a new study of the Perseus Galaxy Cluster using Japan's Suzaku satellite.

Supernova Explosion of Yellow Supergiant Star in March Confirmed

Observational results of the Hubble Space Telescope announced in March 2013 confirmed the theoretical prediction by the Bersten team at the Kavli Institute for the Physics and Mathematics of the Universe that the yellow supergiant star found at the location of supernova SN 2011dh in the famous nearb...

Baby Black Hole of Milky Way May Created by Rare Explosion

A highly distorted supernova remnant shown in the image below may contain the most recent black hole formed in the Milky Way galaxy. The image combines X-rays from NASA's Chandra X-ray Observatory in blue and green, radio data from the NSF's Very Large Array in pink, and infrared data from Caltech's...
