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 Space Telescope has broken its own record in the quest to find the furthest supernova of the type used to measure cosmic distances.
Astronomers believe they've now worked out the details of how supernova remnants can form cosmic rays.
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.
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.
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.
Carnegie Institution for Science scientists believe they've identified a type 1a supernova in the making.
An average of two massive stars in our Milky Way galaxy explode each century, producing magnificent supernovae when they detonate.
A Danish physicist has concluded that the explosion of nearby supernovae has strongly influenced the development of life on Earth.
X-ray and ultraviolet observations from NASA's Swift satellite have given new infoprmation about the origins of Type Ia supernovae.
At the turn of the 19th century, the binary star system Eta Carinae appeared faint and rather undistinguished to astronomers.
The discovery of a supernova just hours after its explosion has given scientists an unprecedented amount of information about such cosmic explosions.
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.
If you're a largely unknown company and you had been working on an Android tablet, right now would be about the worst time to launch it.
Astrophysicist Rosanne Di Stefano compares it to the Hollywood blockbuster 'Speed' - a newly-described type of star that's destined to explode if it slows down.
Berkeley scientists this week discovered a new supernova, closer to Earth than any seen in the last 40 years, and believe they've spotted it within hours of its explosion.
A ten-year-old Canadian girl has become the youngest-ever person to discover a supernova.
New images from the Hubble Space Telescope show an appropriately festive-looking bubble of gas in our neighbouring galaxy, the Large Magellanic Cloud.
While looking for something else entirely, Harvard-Smithsonian astronomers have discovered several double-star systems which are merging, and which may explode as supernovae in the astronomically near future.
Astronomers using ESO’s Very Large Telescope have for the first time been able to see a stellar explosion in 3D.
