The habitability of super-Earths in Gliese 581
Aims: The planetary system around the M star Gliese 581 consists of a hot Neptune (Gl 581b) and two super-Earths (Gl 581c and Gl 581d). The habitability of this system with respect to the super-Earths is investigated following a concept that studies the ...

Teaching Astrobiology Online [PDF]
As part of Swinburne Astronomy Online (SAO), we run an online short course entitled Searching for Extrasolar Planets and Extraterrestrial Life. The main aim of the short course is to act as a “feeder” into our graduate programs and allow students to trial online education while exploring one of the new hot topics of astronomy – astrobiology.I will ...

Perchlorates on Mars enhance the bacteriocidal effects of UV light
Perchlorates have been identified on the surface of Mars. This has prompted speculation of what their influence would be on habitability. We show that when irradiated with a simulated Martian UV flux, perchlorates become bacteriocidal.
