When a massive star reaches the end of its short
life, it explodes as a supernova. For a few weeks, this star will outshine
the combined glow of its galaxy. In 1006 AD, the "Lupus Supernova" shone so
brightly that it was visible for several months in broad daylight! A supernova occurs in our galaxy on average
every 50 years, but as luck would have it, the last one exploded in 1604.
However, 444 million years ago a nearby supernova almost wiped out all life on
Earth, causing the "Ordovician Mass Extinction". Luckily, our Sun is too small to explode this way,
but the familiar stars Betelgeuse, Spica and Antares will. When they do - what
will happen to us?
These and other questions will be answered by Professor Stephen Smartt, of Queens University, Belfast - a leading European authority in this field who is giving our September Public Lecture on Monday.
