Astronomers may have misread cosmic acceleration for 27 years. The universe may be slowing down, not speeding up.

For several decades, evidence has suggested that the expansion of the universe is accelerating. Crucial to those estimates ...

How much light does a supernova shed on the history of universe? New research by cosmologists at the University of Chicago and Wayne State University confirms the accuracy of Type Ia supernovae in ...

Astronomers recognize three flavors of type I supernovae: type Ia, Ib, and Ic. Type Ia supernovae occur in binary systems, where matter from a normal companion star flows onto a white dwarf. The white ...

In a controversial new paper, researchers argue that the acceleration of the universe's expansion has slowed down.

Distant exploding stars observed by NASA’s Hubble Space Telescope are providing astronomers with a powerful tool to determine the strength of naturally occurring “cosmic lenses” that are used to ...

Supernovae mark the dramatic end of a massive star's life that results in a colossal explosion. Supernovae mark the dramatic end of a massive star's life, resulting in a colossal explosion that can ...
