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.

Late night until dawn: Perseid Meteor Shower

 

Elk Island National Park
On the shores of Astotin Lake

The Perseids are perhaps the most popular meteor shower of the year; and this year, they’ll be the best shower of the year. This year, during the peak, people should see about 60-70 meteors per hour. The meteor shower’s peak will be visible both the nights of Aug 11-12 and Aug 12-13.

This year, the peak of the meteor shower will occur near New Moon – the Moon will be a crescent, which means it will set before the Perseid show gets underway after midnight. The Moon is very favorable for the Perseids this year, and that will make the Perseids probably the best shower of 2018 for people who want to go out and view it. The Perseids are rich in fireballs, so the show should be even better.

Perseid meteors tend to strengthen in number as late night deepens into midnight, and typically produce the most meteors in the wee hours before dawn. Skywatchers looking out for the Perseids should also be able to see Mars (visible until about 3 AM) and Saturn (visible until about 2 AM). As evening falls, Venus will be low in the West and Jupiter will be a bit higher in the Southwest – both planets set before the Perseid meteor shower.
