NASA’s Solar Dynamic Observatory this week (Oct 2) captured an M7.3 flare, a mid-sized flare that posed little threat to Earth. It did however provide a spectacular show for SDO to capture and send back to NASA. Capturing the immense power of our favourite star as magnetic loops larger than planets burst from the suns surface.
Presented for your viewing pleasure is the latest video to come from our eyes in the sky, SDO staring at the Sun. Sit back, relax and let the solar dance began.

Learning about the Sun and our relationship to it is of great importance to NASA, and all of us. The fact that from time to time incredible videos result from the science, that’s just a bonus.
Two of the most spectacular videos to come from all of this staring at the Sun capture the Sun at its explosive and fiery best. The Graceful Eruption and the Magnificent Eruption videos both capture massive CME events occurring on the surface of the sun, both of them spectacular.
Presented for your viewing pleasure are two of the best examples of CME action captured by the SDO satellite. Capturing the Sun as it sheds immense amounts of energy and matter. Sit back, relax and let the solar storm begin.

With the solar maximum of 2012 building up the sun is putting on quite a show for us all. The sun, our all gas jolly giant is due to reach the peak of its solar flare activity in 2013. The peak called Solar Maximum is generating a lot of interest. Scientist have calibrated instruments, created classifications, the rest of us just have to sit back and enjoy the wild ride. We actually know a lot about how the flares happen we just can’t do much about it.
Solar flares – also called Mass Coronal Ejection – consist mainly of super excited protons and electrons, heated to millions of degrees before spewing out of the sun. The individual particles don’t have enough mass to do any direct damage, no bullets from the sun, but collectively there is so much energy being sent out in the flare that they can be very dangerous. At most risk are astronauts and soon to join them space tourists. When travelling outside the Earths magnetic field the radiation – especially X-rays and Gamma rays – is extremely dangerous to living organisms, doing damage to each cell in your body. Currently no space craft are able to completely protect its crew from this radiation. Ironically Solar Flares actually cut the number of cosmic rays hitting Earth by deflecting the stream – solar wind – of particles.
