M87

We return to a space theme with today’s wallpaper, which is an image taken by the famous Hubble Space Telescope of the distant active galaxy M87. An active galaxy is one with a core that is much brighter than we would expect, and it thought to be caused by a supermassive black hole at the centre of the galaxy pulling in and destroying vast quantities of matter. This image shows a huge blue jet of matter, 5,000 light-years long, that has been ejected by the galaxy and is hurtling through intergalactic space. The blue light comes from the highly energetic particles that make up the jet. This stunning image makes a perfect desktop wallpaper for anyone with an interest in astronomy.
