New view of supernova death throes

A powerful, new three-dimensional model provides fresh insight into the turbulent death throes of supernovas, whose final explosions outshine entire galaxies and populate the universe with elements that make life on Earth possible.

Closest, brightest supernova in decades is also a little weird

A bright supernova discovered only six weeks ago in a nearby galaxy is provoking new questions about the exploding stars that scientists use as their main yardstick for measuring the universe.

Spitzer stares into the heart of new supernova in M82

The closest supernova of its kind to be observed in the last few decades has sparked a global observing campaign involving legions of instruments on the ground and in space, including NASA's Spitzer Space Telescope. With its dust-piercing infrared vision, Spitzer brings an important perspective to this effort by peering directly into the heart of the aftermath of the stellar explosion.

NASA spacecraft take aim at nearby supernova

An exceptionally close stellar explosion discovered on Jan. 21 has become the focus of observatories around and above the globe, including several NASA spacecraft. The blast, designated SN 2014J, occurred in the galaxy M82 and lies only about 12 million light-years away.

A closer look at a supernova's super dust factory

Galaxies can be remarkably dusty places and supernovas are thought to be a primary source of that dust, especially in the early Universe. Direct evidence of a supernova's dust-making capabilities, however, has been slim and cannot account for the copious amount of dust detected in young, distant galaxies.

Supernova blast provides clues to age of binary star system

Data from NASA's Chandra X-ray Observatory has revealed faint remnants of a supernova explosion and helped researchers determine Circinus X-1 -- an X-ray binary -- is the youngest of this class of astronomical objects found to date.

Mach 1000 shock wave lights supernova remnant

When a star explodes as a supernova, it shines brightly for a few weeks or months before fading away. Yet 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?

Understanding Kepler's supernova

An analysis of X-ray observations from the Japan-led Suzaku satellite indicates that an exploding star observed in 1604 by the German astronomer Johannes Kepler held a greater fraction of heavy elements than the sun.

NASA's Hubble spots a far-away supernova

NASA's Hubble Space Telescope has broken its own record in the quest to find the furthest supernova of the type used to measure cosmic distances.

Clue to origin of cosmic rays

Astronomers believe they've now worked out the details of how supernova remnants can form cosmic rays.

New 'cosmic candle' could help explain dark matter

Mingus - or more formally, SN SCP-0401 - is a Type Ia supernova with a redshift of 1.71, dating back 10 billion years. It's exceptional for its detailed spectrum and precision color measurement, unprecedented in a supernova so distant, says the team.

Brightest-ever supernova explained

Astronomers reckon they've found the cause of the brightest stellar event ever recorded: a supernova first observed on April 30 1006 that continued to shine for three years.

Hubble snaps a supernova in NGC 5806

NASA has released an image of a supernova (SN 2004dg) that occurred in NGC 5806, a spiral galaxy in the constellation Virgo (the Virgin) located approximately 80 million light years from Earth.

Scientists spot supernova before it blows

Carnegie Institution for Science scientists believe they've identified a type 1a supernova in the making.

Exploring the heart of a supernova

An average of two massive stars in our Milky Way galaxy explode each century, producing magnificent supernovae when they detonate. 

Nearby supernovae affect climate, and help life thrive

A Danish physicist has concluded that the explosion of nearby supernovae  has strongly influenced the development of life on Earth.

Swift satellite throws light on origins of supernovae

X-ray and ultraviolet observations from NASA's Swift satellite have given new infoprmation about the origins of Type Ia supernovae.

NASA previews Eta Carinae supernova

At the turn of the 19th century, the binary star system Eta Carinae appeared faint and rather undistinguished to astronomers.

Supernova observations yield new answers

The discovery of a supernova just hours after its explosion has given scientists an unprecedented amount of information about such cosmic explosions.

Christmas gamma ray burst explained?

Astronomers have come up with two competing theories to explain a mysterious cosmic explosion first detected by NASA's Swift observatory on Christmas Day 2010.
