At least one supernova occurs per decade in our galaxy .

Then almost a half-century after determining that it was a supernova astronomers figured out how the supernova proceeded .

The problem has been that predicting exactly when a star will go supernova is nearly impossible .

The chances of a planet surviving a supernova always looked terribly slim .

Astronomers observe approximately one supernova every year in the universe .

A supernova is the last stage of stellar evolution and is a violent astrophysical phenomena .

Some supernova researchers wondered if it might be just a nine-day wonder .

Astronomers have suspected for more than a decade that supernova shock waves can act like giant particle accelerators .

Nevertheless other isotopes suggest a supernova did go off just as the solar nebula was forming .

The supernova explosion disrupts the binary .

u8d85 u65b0u661fu7206u53d1u4f1au74e6u89e3u53ccu661fu7cfbu7edfu3002

Supernova explosions are immensely complicated events .

The most natural drivers of this preheating were supernova explosions .

When a star collapses it can become either a White Dwarf or a Supernova .

The ejected mass then probably becomes the observed material of a supernova outburst .

A supernova is a violent explosion that happens to the most massive stars .

When a large star has burnt all its fuel it explodes into a supernova .

If the collapse if not perfectly spherical the supernova will give off an intense burst of gravitational waves .

Perhaps we even think that maybe supernova explosions trigger formations of planets and stars .

But calculations indicated that fields of interstellar gas would have dissipated a supernova 's radiation and blunted its impact .

One way this may happen is if a supernova explodes nearby .

When a star collapses it will be White dwarf or Supernova .

The hot gas will be heated further by any supernova which go off in the galaxy .

These filaments are seen in other supernova remnants such as Cassiopeia A Tycho and Kepler .

Consequently mysteries have remained about a supernova 's earliest moments .

In 1987 the brightest supernova in recent history occurred in the Large Magellanic Clouds .

Supernova were reported by astronomers in the seventeenth and eighteenth centuries .

The new star was visible for months and is thought to be the earliest recorded supernova .
