Study Confirms Two Different Sources for Type Ia Supernovae
A newly published study from the Harvard Smithsonian Center for Astrophysics details two models supporting the origin of Type Ia supernovae, finding that both the…
Origins of Type Ia Supernovae
While studying SN 2011fe and using X-ray and ultraviolet observations from NASA’s Swift satellite, researchers were able to provide new insights into the origins of…
Hubble Telescope Image of Eta Carinae
At the turn of the 19th century, the binary star system Eta Carinae was faint and undistinguished. In the first decades of the century, it…
Spectra Creates Doubt on Cause of Eta Carinae Stellar Explosion
One hundred and seventy years ago, astronomers thought that a series of explosions on the surface of Eta Carinae (η Carinae) were the beginning of…
Possible Evidence of Hadron Acceleration in Tycho Supernova Remnant
Recent gamma-ray observations of Tycho’s supernova remnant (SN 1572) by the space-based Fermi-Large Area Telescope (Fermi-LAT) and the Very Energetic Radiation Imaging Telescope Array System…
Links Between Core Collapse Supernovae and Star Formation Established
When massive stars accumulate more iron than they can hold, they explode in what is called a core-collapse supernova, also known as Type II…
Lasers Mimic Supernova to Explain Cosmic Magnetic Fields
Scientists are using powerful lasers to mimic the effects of supernovae, which are helping to reveal how the magnetic fields of galaxies may have been…
SN Primo Is Farthest Type Ia Supernova Discovered
Supernova Primo originated 9 billion years ago, when its progenitor star exploded. The light was captured by the Hubble Space Telescope by a three-year project…
Youngest Supernova Photographed
The death of a star has been captured on film just fourteen days after the explosion occurred, marking the supernova in the galaxy Galàxia del…
