BERKELEY, CA — A group of scientists affiliated with the SuperNova Legacy Survey (SNLS) have found startling evidence that there is more than one kind of Type Ia supernova, a class of exploding stars ...
Three years after its explosion, a type Ia supernova continues to shine brighter than expected, new research finds. The observations, made with the Hubble Space Telescope and published today in The ...
Astronomers have discovered evidence that could help solve a long standing dispute over the origin of Type Ia supernovae, by observing the youngest example of the titanic explosions located to date.
The exploding stars known as Type Ia supernovae serve an important role in measuring the universe, and were used to discover the existence of dark energy. They’re bright enough to see across large ...
Supernovae, categorized as Type I (low hydrogen) and Type II (high hydrogen), produce varying abundances of heavy elements. Type Ia supernovae, resulting from thermal runaway in white dwarfs, are rich ...

Are astronomers wrong about dark energy? New study casts doubt on universe’s accelerating expansion
A new study casts doubt on the universe’s accelerating expansion, suggesting dark energy might be weakening over time.
May 8 (UPI) --The discovery of Type Ia supernovae with hydrogen, a rarity, could help astronomers trace the origins of the explosive cosmic phenomena. Type Ia supernovae occur when the white dwarf in ...

Hubble helps explore the wreckage of a supernova star explosion in a satellite galaxy of the Milky Way (image)
Using the Hubble Space Telescope and an array of other instruments, astronomers have probed supernova wreckage in the Large ...
For the first time, astronomers have caught a type Ia supernova being magnified by more than 50 times and split into four images in the night sky thanks to gravitational lensing. The discovery, ...
Astronomers know that when a star runs out of fuel and reaches the end of its life, it may go through an epic final stage in which it explodes in a tremendous output of energy called a supernova. But ...
Ever since Edwin Hubble's 1929 discovery that the universe is expanding, astronomers have known that the more distant a galaxy, the faster it's traveling away from us. They've long wondered to what ...
