The sun is in the midst of its quietest period in more than a century. Several days ago, it was in 'cue ball' mode, with an incredible image from Nasa showing no large visible sunspots seen on its surface
Celestial Fireworks - Hubble by Deep Space Photography - Resembling the puffs of smoke and sparks from a summer fireworks display in this image from NASA's Hubble Space Telescope, these delicate filaments are actually sheets of debris from a stellar explosion in a neighboring galaxy.
Astronomers have found a way to accurately measure the spin of a supermassive black hole for the first time and as expected, it's pretty darn fast -- nearly-the-speed-of-light fast. The black hole in question resides 60 million light years away at the centre of the NGC 1365 spiral galaxy, is a mind-boggling 3.2 million kilometres in diameter, has a mass two million times that of our Sun and is spinning at a rather impressive 1.08 billion km/h. http://www.wired.co.uk/
