Black Holes Don’t Suck!

Often portrayed as cosmic vacuum cleaners that ensnare everything that dares come close, black holes represent the ultimate end, in both science fact and science fiction. First theorized in the early 20th century, black holes have fascinated astronomers for the last 100 years. I will discuss the history of these systems, from the accidental discovery of Sagittarius A* at the centre of our Galaxy by Karl Jansky in the 1930s, to the violent accretion events occurring in X-ray binary systems and active galactic nuclei. I will show you that, contrary to popular belief, black holes don’t suck!

Bold colour images from telescopes act as extraordinary ambassadors for astronomers

because they pique the public’s curiosity. But are they snapshots documenting physical
reality?  Or are we looking at artistic spacescapes created by digitally manipulating
astronomy images? This lecture provides a tour of how original black and white data from the Hubble Space Telescope, as well as current cutting-edge observatories, are converted into striking colour images. It illuminates how practices from the art world are used to produce media friendly images which still retain scientific value.
