March 19 will be a good day for photographers and astronomers. The moon will be the biggest, fullest it has been for 18 years. This point of the moons orbit – where it is closest to Earth – is known as the Lunar Perigee.
While this is common, this closeness happens every 9 years, it doesn’t often coincide with a full moon. As long as there is a clear sky in your neighborhood get ready for a big moon. Even with binoculars or a good zoom lens on your camera you will be able to see incredible detail.
A combination of effects have aligned to put this show on for us all. The elliptical orbit of the moon – it’s sometimes called our Eccentric Companion – along with Earths elliptical orbit and the gravitational effects of the sun mean the moon will be 30,000km closer to earth than usual – normally it’s 354,000km from earth.

Aerogel. Our favourite almost there material
AeroGel – Frozen Smoke, so called as it has a transparent smokey look – has added another use to its growing list of can do’s. Scientists at the University of Southern Florida are working to develop batteries using the material. There is something impossible about this strange material, something very cool.
So what makes AeroGel so great? Firstly it’s 99.98% air but still manages to be a solid, there is literally nothing too it. It has the texture of polystyrene when you hold it but it looks fairy floss. It is a great insulator of both heat and electricity. Currently it holds 15 Guinness World Records for various properties, worlds lightest solid, worlds lowest density solid, worlds highest insulation value. It is an extreme material, it doesn’t do that many things but what it does do is always a world record.

Is a Pole Shift underway as we speak ? A geomagnetic reversal could have dire effects on our high tech lifestyles, temporarily knocking us back into the dark ages, time to get ready to be cave men again. If worst the case scenarios eventuates.
The British Geological Survey has reported as part of the ‘South Atlantic Anomaly and South Georgia Magnetic Observatory’ report that there may be some signs of the Earths magnetic pole shifting, a geomagnetic reversal.
The magnetic poles of the Earth are part of the magnetic field that surrounds the earth. This field is generated by the spinning core of the earth just like an electric motor and the poles are just the same as the poles on a bar magnet. While the earths North and South pole do wander around a bit, if you were to make timed observations of a compass you would see slight movements in where the compass points, a pole reversal refers to the switching of North and South magnetic poles, in effect the compass needle would swing 180 degrees. Once the poles have swapped place things continue on as normal, it makes surprisingly little difference which is actually north and south.

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.
