Nearby supernova ashes continue to rain on Earth
Traces of 60Fe detected in space indicate that a nearby supernova occurred within the last few million years. The iron isotope 60Fe, which is very rare, is created when a massive star collapses in the form of supernova. (2016-04-21)

XMM-Newton's anniversary view of nearest detected supernova

Mach 1000 shock wave lights supernova remnant
When a star explodes as a supernova, the material blasted outward from the explosion still glows hundreds or thousands of years later, forming a picturesque supernova remnant. What powers such long-lived brilliance? In the case of Tycho's supernova remnant, astronomers have discovered that a reverse shock wave racing inward at Mach 1000 (1,000 times the speed of sound) is heating the remnant and causing it to emit X-ray light. (2013-11-25)

Ultraviolet light from superluminous supernova key to revealing explosion mechanism
An international team of researchers led by Kavli IPMU's Alexey Tolstov and Ken'ichi Nomoto have discovered a way to use UV light from superluminous supernovae to uncover its explosion mechanism, and used it to identify Gaia16apd as a shock-interacting supernova, reports a new study. (2017-09-07)

Revealed: The explosive origin of superluminous supernova SN 2006gy
Providing answers about its curious supreme brightness, researchers say the superluminous supernova SN 2006gy -- one of the brightest stellar explosions ever studied, and discovered in 2006 -- gained its exceptional luster when a normal Type Ia explosion smashed into a surrounding shell of ejected stellar material. (2020-01-23)

U of A physicist identifies mysterious core left by exploding star
University of Alberta physics professor Craig Heinke has solved a mystery that lies 11,000 light years beyond Earth. A supernova (or exploding star), 20 times heavier than our sun blasted apart, leaving behind a small core that has puzzled astronomers since its discovery in 1999. (2009-11-04)

Pan-STARRS finds a 'lost' supernova
Supernova explosions of massive stars are common in spiral galaxies like the Milky Way, where new stars are forming all the time. They are almost never seen in elliptical galaxies where star formation has nearly ceased. As a result, astronomers were surprised to find a young-looking supernova in an old galaxy. (2013-03-07)

NASA'S Swift sees double supernova in galaxy
In just the past six weeks, two supernovae have flared up in an obscure galaxy in the constellation Hercules. Never before have astronomers observed two of these powerful stellar explosions occurring in the same galaxy so close together in time. (2007-06-26)

This image, taken with NASA's Hubble Space Telescope, shows the supernova remnant SNR 0509-68.7, also known as N103B. It is located 160,000 light-years from Earth in a neighboring galaxy called the Large Magellanic Cloud. N103B resulted from a Type Ia supernova, whose cause remains a mystery. (2017-03-30)

Supernova remnant menagerie
A violent and chaotic-looking mass of gas and dust is seen in this Hubble Space Telescope image of a nearby supernova remnant. Denoted N 63A, the object is the remains of a massive star that exploded, spewing its gaseous layers out into an already turbulent region. (2005-06-07)

Hubble watches exploding star fade into oblivion
When a star unleashes as much energy in a matter of days as our Sun does in several billion years, you know it's not going to remain visible for long. Like intergalactic paparazzi, NASA's Hubble Space Telescope captured the quick, fading celebrity status of a supernova, the self-detonation of a star. (2020-10-01)

X-Ray Structure In Supernova Remnants Linked To Age
A team of astronomers studying supernova remnants has found direct evidence linking the pattern of their X-ray emission to the size -- and therefore, age -- of the remnants. (1999-02-04)

Spectacular supernova's mysteries revealed
The new research into its cause, published in the latest issue of the Astrophysical Journal, used vast networks of radio telescopes in the UK and across Europe including the seven telescopes of e-MERLIN operated from The University of Manchester's Jodrell Bank Observatory. These enabled them to obtain extremely deep images revealing a lack of radio emission from the supernova. (2014-08-22)

Supernova explosions stay in shape
A new study of images from NASA's Chandra X-ray Observatory on supernova remnants -- the debris from exploded stars -- shows that the symmetry of the remnants, or lack thereof, reveals how the star exploded. This is an important discovery because it shows that the remnants retain information about how the star exploded even though hundreds or thousands of years have passed. (2009-12-17)

Little supernova is big discovery: The origin of binary neutron stars
An international research team discovered the first recorded 'ultra-stripped supernova,' a rare, faint type of supernova that is believed to play a role in the formation of binary neutron star systems.

Fear no supernova
Given the incredible amounts of energy in a supernova explosion -- as much as the sun creates during its entire lifetime -- another erroneous doomsday theory is that such an explosion could happen in 2012 and harm life on Earth. However, given the vastness of space and the long times between supernovae, astronomers can say with certainty that there is no threatening star close enough to hurt Earth. (2011-12-16)

Astronomers see historical supernova from a new angle

Surprising neutrino decoherence inside supernovae
Neutrinos produced in the core of a supernova are highly localized compared to neutrinos from all other known sources. These findings are published in EPJ C by Jörn Kersten from the University of Bergen, Norway, and his colleague Alexei Yu. Smirnov from the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. With a new estimate for an entity characterizing neutrinos, they suggest that the wave packet size is irrelevant in simpler cases. (2016-07-12)

An international team of researchers has found evidence that the brightest stellar explosions in our Universe could be triggered by helium nuclear detonation near the surface of a white dwarf star. Using Hyper Suprime-Cam mounted on the Subaru Telescope, the team detected a type Ia supernova within a day after the explosion, and explained its behavior through a model calculated using the supercomputer ATERUI. This result was reported in Nature published on Oct. 5. (2017-10-04)
