    SOLAR FLARE: Emerging over the sun's southeastern limb, sunspot AR1389 unleashed an M2-class solar flare at 1350 UT on Dec. 29th. The blast shows that the newly-visible sunspot is capable of significant eruptions. AR1389 is not yet facing Earth, but it is turning in our direction.

    On December 30, 2011 there were 1272 potentially hazardous asteroids.

    Please have a safe trip if traveling outside our atmosphere :wink:

    I get updates on this stuff from my radio group as it can affect radio transmission and reception. I always find it amusing that we humans get on with our everyday lives largely unaware that the Sun is a wildly active entity and can affect us in many subtle ways without a great deal of warning.

    A 80m wide lump of matter also shot by at 13kmps less than 3 times the distance of the moon on the 26th, close call.

    It's been a wild year on earth with nature unleashing some of its force but all of that is miniscule compared to what our star or others can unleash on the planet.

    I watched this over Christmas http://www.youtube.com/watch?v=U1yIWOiDMZw&feature=share which has a funny bit at the end. Which seems to be about this http://wtfdiam.stevenredhead.com/photonbelt.html

    It seems to be about the 2012 midpoint of our oscillation around the center of the milky way. Stating there is some high energy beam we pass through. Now this seems a bit conspiracy theory to me and the idea that we need a Mars base to survive, as stated in the video. Its the last bit of the video. If there is some high energy space thing it's just as likely to affect Mars too.

    But it does show a real threat. http://www.lifeslittlemysteries.com/1007-will-betelgeuse-really-become-second-sun.html Betelgeuse might or might not send destructive bursts of energy to earth and may not explode for a long time, but we never know what might be drifting toward our solar system.

    Humans will never be assured of survival at least until we are living in a couple of solar systems, if not a couple of galaxies...

    Nice amateur blog on the event.

    If you missed it catch the Horizon show on Sun spots, fascinating.

    Recent & Upcoming Earth-asteroid encounters:

    Upcoming near misses include the 2012 DH54 only just over 3 time the distance of the moon and a tiny 13m in size followed by1999 RD32 the huge 2.4km chunk of space debris which is staying a respectful 50+ lunar distances from us.

    Brilliant imaging nowadays - it really is amazing the detail. Every time I see something like this is reminds me of a fantastic June 1976 episode of Horizon entitled: "What's Wrong With The Sun?" which was probably the first time I realised how dynamic our local star was and how much there was still to learn about its physics.

    Who would have thought that a massive burning ball of plasma and stuff would be so wild :p:

    It's easy to underestimate the scale of those pictures too....

    This is brilliant!!!! Really really good at putting scale in a way people can easily understand.

    Just one question - HOW BIG IS ANTARES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    About the size of a tennis ball according to my screen, although I'm fairly sure my computer has scaled it somewhat....
