http://www.spaceweather.com/ "Daily Sun: 26 Mar 09 The Sun is blank--no Sunspots. Sunspot number: 0" "Far side of the Sun: This holographic image reveals no sunspots on the far side of the sun." The face of the Sun is without blemish: http://www.spaceweather.com/images20...hsb7riej e854 Please visit: http://blog.nj.com/southjersey_impac...SolarCycle.jpg The right panel shows the face of the Sun as it looked on a good day during the late Modern Warm Period. Sunspots are the apparent size of craters on the moon. The left panel shows a Sun as it appears today. Please write to Al Gore so that Al knows that the Sun is not living up to his religious expectations. Al Gore is a divinity school dropout. George Carlin had a better grasp of the true nature of God's creation, than does Al Gore. Please visit: http://www.co-intelligence.org/newsl...es/sun-etc.jpg which shows the relative sizes of the Sun and planets. Compared to the Sun, Jupiter is the size of a pea, earth is the size of a grain of sand. Scientists recover pieces of asteroid previously tracked by telescope By Daily Mail Reporter Last updated at 1:37 AM on 26th March 2009 Scientists have for the first time recovered pieces of an asteroid previously tracked through space by a telescope, it was revealed today. The car-sized asteroid was spotted last October before it exploded over the Nubian Desert in northern Sudan. Researchers recovered 47 meteorite fragments from the desert, giving them the first opportunity to analyse an asteroid previously seen in space. 'Any number of meteorites have been observed as fireballs and smoking meteor trails as they come through the atmosphere. It's been happening for years. 'But to actually see this object before it gets to the Earth's atmosphere and then to follow it in - that's the unique thing,' said Douglas Rumble, of the Carnegie Institution's Geophysical Laboratory. Mr Rumble has since written a research paper on the discovery published today in the journal Nature. The compositions of asteroids can be studied through a telescope by analysing the way sunlight reflects from their surfaces. Although this allows scientists to divide them into broad categories, it does not provide detailed enough information for their exact make-up to be determined. When the asteroid, known as 2008 TC3, was first spotted on October 6 by telescopes from the Catalina Sky Survey near Tucson, Arizona, it was tracked until it disappeared in to the Earth's shadow. After it vanished, Peter Jenniskens, of the SETI Institute in California, and Muawia Shaddad, from the University of Khartoum in Sudan, started searching for meteorites along its projected path. Dr Jenniskens, lead author of the paper, said: 'This asteroid was made of a particularly fragile material that caused it to explode at a high 37 kilometre altitude, before it was significantly slowed down, so that the few surviving fragments scattered over a large area. 'The recovered meteorites were unlike anything in our meteorite collections up to that point.' One known asteroid with a similar spectrum, the 2.6 kilometre-sized asteroid KU2 from 1998, has already been identified by researchers as a possible source for the one that exploded over Earth last October.
