It is now generally accepted that at the centre of active galaxies lies a black hole, which is accreting a disk of gas. Some of these disks produce jets, highly energetic plumes of hot, ionized gas which are propelled by twisted magnetic fields in the galaxy's gas.

In this project you will use data taken with the Faulkes Telescopes to produce a colour image of the active galaxy, M87 and its jet, and measure the size of the jet using SalsaJ.
