Bangers and MASH - positively glowing with excitement
Clouds of hydrogen in space are usually called nebulae, due to their
misty (or 'nebulous') appearance. Surprisingly, they are a bit like
human beings - they glow pink when they get excited.
Back in 1997, scientists at the UK Schmidt Telescope in northwestern
NSW began a successful six-year search for such pink clouds. Among
the interesting objects that came to light were 'bangers' (the
remnants of exploding stars) and MASH (objects in the Macquarie Uni/
Anglo-Australian Observatory/Strasbourg H-alpha planetary nebula
Studying these objects in detail helps astronomers understand the
processes that take place at the end of a star's life, and can give
us insights into what will eventually happen to our own Sun.
In this entertaining and fully-illustrated talk, Fred Watson explains
how 'bangers and MASH' fit into the grand scheme of the Universe, how
the search for them was conducted, and what the results are telling us.
Professor Watson is the astronomer-in-charge at the Anglo-Australian
Observatory. He appears regularly on ABC radio and television, writes
a column for Australian Geographic magazine and is the author of two
books, Stargazer – The Life and Times of the Telescope and Why is
Uranus Upside Down? for which he won the Queensland Literary Prize
Professor Watson's talk takes place within a three-day international
workshop on stars in a late stage of their lives.
