A quasar (also known as a QSO or quasi-stellar object) is an extremely luminous active galactic nucleus (AGN). It has been theorized that most large galaxies contain a supermassive central black hole with mass ranging from millions to billions of solar masses. In quasars and other types of AGN, the black hole is surrounded by a gaseous accretion disk. As gas in the accretion disk falls toward the black hole, energy is released in the form of electromagnetic radiation. This radiation can be observed across the electromagnetic spectrum at radio, infrared, visible, ultraviolet, and X-ray, and gamma wavelengths. The power radiated by quasars is enormous: the most powerful quasars have luminosities exceeding 1041 watts, thousands of times greater than an ordinary large galaxy such as the Milky Way. Wikipedia
I feel strangely attracted (heh) to images of galaxies, black holes, and any combination of them (
click and
click) so it felt kind of like a must to go into this direction one day or the other again. When I read about the
Nature Wallpaper Contest, this felt like the perfect opportunity to paint one of the largest natural objects known to mankind (excluding these dreaded superclusters for the sake of getting my point across
). In the end, it kind of turned out like a hybrid between a nebula and a galaxy...
Anyway, added bonus: it's a wallpaper-pack! Included sizes are:
1920x1080
1920x1200
1600x1200
Just hit the download-button, unpack the zip, and decorate your desktop with spacey goodies
As always, if you feel like motivating me to create more of this kind of stuff, I love any kind of support, comments, favs,
points, watches, you name it! Thank you
