An explosion seen in the cosmos in the early 1600s may actually be an "Alien Type Ia supernova", according to a new paper. In ...

Astronomers working with the European Southern Observatory’s (ESO) Very Large Telescope (VLT) have detected patterns showing ...

When I joined Phenomena, Carl Zimmer asked: What obsesses you? Among my obsessions, I answered, are type 1a supernovae. Here we go. How can an astronomical object of such crucial cosmological ...

An important difference between these two progenitors is that the two white dwarfs are expected to be consumed in the explosion, whereas a companion star should survive the supernova. As a result, ...

New observations show a star that blew up in two separate bursts, confirming a long-suspected cosmic phenomenon called a ...

A recurrent nova in the Andromeda Galaxy is likely to become the next nearest Type 1a supernova.

Type 1a supernovae are a special type of cosmic explosion. They occur when a white dwarf–the dense remnant core of a star–takes in too much mass.

The “sphere” is likely the result of a Type 1a supernova shockwave, though astronomers aren’t sure exactly how far away the this supernova remnant is from Earth—either 7,175 light-years or ...

Astronomers have discovered an extremely rare, high mass, compact binary star system only ~150 light years away. These two stars are on a collision course to explode as a type 1a supernova ...

Observations investigate the connection of a supernova remnant with a nearby H II region Chinese astronomers have performed multi-wavelength observations of a galactic supernova remnant known as HB9.
