Pondering questions such as What is in an exoplanet name Sunspots and flares As we head towards the maximum of the Sun's 11 year cycle of activity , the Sun's surface is becoming much more interesting . Although here in the UK we've had awful weather for the past month or two , the sudden improvement of the past couple of days has meant we're able to see huge sunspot 1476 which is launching solar flares in our direction . Here is my photo taken a few minutes : ago The Sun seen at the eyepiece of a Coronado PST 12 May 2012 : CREDIT Stuart It isn't the best picture ever but you can see the sunspot to the left of centre as well as some prominences around the edge .

Pondering questions such as What is in an exoplanet name Asteroids 1980-2011 Via Alberto Conti I re-discovered an animation from last year that shows the discovery of over 500,000 asteroids since 1980 The video shows the planets orbiting the Sun and each asteroid discovery is highlighted when it happens . As time runs into the 2000s the pace really picks up and the asteroid belt becomes incredibly obvious . You should quickly spot that the discoveries occur on the side of the Earth facing away from the Sun i.e . when it's night although there are some interesting evening morning discovery wedges in 2010 and I'm not sure . why Tags : asteroids video animation
