Other discoveries in the Milky Way detailed in the special edition include the sharpest image yet of a gamma ray source — a nearby supernova remnant — which will enable researchers to study this object at finer scale than before — and three new «gamma ray shells» that are possibly examples of a new type of supernova remnant.

Although this looks like a single nebula, NSF's Gemini South Observatory revealed it is actually two separate gas and dust clouds formed by different types of supernova explosions.

Since the Type Ia supernova form from the collapse of a stellar core of a particular mass, rather than the range of core masses possible for the other types of supernova, the Type Ia supernova are expected to have the same luminosity.

Last April astronomical detectives announced a break: An orbiting X-ray observatory picked up the chemical fingerprints of several elements in a burst's afterglow, identifying the object as an unusual type of supernova — the detonation of a massive, dying star.

Astrophysicists think that this process is what powers a common type of supernova explosion, known as Type II.

Theorists have gradually ratcheted up the sophistication of their models and have recently succeeded at last in reproducing the two main types of supernovae.

They planned to do so by carefully calibrating the brightness of a well - studied type of supernova in very distant galaxies.

The discovery beautifully confirms the commonly accepted theory behind the formation of a particular type of supernova.

It is this same type of supernova that led to the discovery of Dark Energy in the Universe using the Keck Observatory, and three Nobel prizes.

These strange GRBs appear to occur at the same rate as certain types of supernovae, called Types Ib and Ic, which occurs when the core of a massive star implodes.

iPTF14hls looked like an ordinary type of supernova in a galaxy about 500 million light - years away.

She accepted an offer from a group of astronomers at Berkeley, part of a collaboration studying a rare type of supernova that some believe holds the key to measuring the expansion of the universe.

This explosion is called a Type Ia supernova to distinguish them from the other types of supernova that occurs when a massive star's core implodes to form a neutron star or black hole.

The finding could challenge the textbook wisdom of single stellar evolution, and provide a critical link to some types of supernovae discovered over the past decade.

For the first time, astronomers have captured in visible light an exploding star's «shock breakout» — an extremely brief window into what triggers one type of supernova.
