Do aliens walk among us? Have we been
visited before? Are they out there watching…
listening…studying us? And if they are out
there, where might ‘there’ be? Our Milky Way
can be a nasty and inhospitable place for
life to develop, but all is not lost. There are
some very unique and special places hidden
amongst this hostile environment where the
building blocks for life might be just right for
extraterrestrial life to flourish.
Brad Gibson is a Professor of Astrophysics. He completed his MSc and PhD at the University of British Columbia, building the world’s first Liquid Mirror Telescope Observatory. He was responsible for using exploding stars to determine the expansion rate of the Universe (as part of the Hubble Space Telescope Key Project), for which his team was awarded the Gruber Prize in Cosmology. Clearly a busy guy, he also discovered the first evidence that our own Milky Way’s nearest neighbours were being cannibalised by our Galaxy. Who better
to answer the question: alien worlds and
extraterrestrial life – where are they?!
