In this example there are four couples of pink and brown bands at the base, followed by a few whitish bands and then an overall lighter pattern before ending up in the black cherts.

The cracks have been filled likely with calcite, but they stop at the edge of the iron layer: you can not follow the cracks into the chert, indicating that the iron was already a solid rock when the chert, above and below, was plastic enough to flow following the deformation.

Magnificent CME Erupts on the Sun with Earth to Scale (por NASA Goddard Photo and Video) On August 31, 2012 a long filament of solar material that had been hovering in the sun’s atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled at over 900 miles per second. The CME did not travel directly toward Earth, but did connect with Earth’s magnetic environment, or magnetosphere, causing aurora to appear on the night of Monday, September 3. The image above includes an image of Earth to show the size of the CME compared to the size of Earth. Credit: NASA/GSFC/SDO

ISS027-E-036747 (by NASA: 2Explore) 23 May 2011 —- This image of the International Space Station and the docked space shuttle Endeavour, flying at an altitude of approximately 220 miles, was taken by Expedition 27 crew member Paolo Nespoli from the Soyuz TMA-20 following its undocking on May 23, 2011 (USA time). The pictures taken by Nespoli are the first taken of a shuttle docked to the International Space Station from the perspective of a Russian Soyuz spacecraft. Onboard the Soyuz were Russian cosmonaut and Expedition 27 commander Dmitry Kondratyev; Nespoli, a European Space Agency astronaut; and NASA astronaut Cady Coleman. Coleman and Nespoli were both flight engineers. The three landed in Kazakhstan later that day, completing 159 days in space.

This extraordinary view of our planet Earth offers a very brief sneak peek #FromSpace of an exciting project we’re working on for @FragileOasis. With our thanks to musician and pioneering advocate for human rights, Peter Gabriel. ”Did you think that your feet had been bound by what gravity brings to the ground? Did you feel you were tricked by the future you picked? Well, come on down …”

What’s it Like at the Centre of the Earth? - Horizon: The Core - BBC Two (by BBC)

http://www.bbc.co.uk/programmes/b0148vph The earth’s inner core is made of iron nickel alloy. But what happens to it under the immense temperatures and pressures found there? Professor Kei Hirose spent 10 years devising an experiment to recreate these extreme conditions. Here he reveals the results…

“It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the plant Earth. I didn’t feel like a giant, I felt very, very small.” This is probably my favorite quote. It is from Apollo 11 astronaut Neil Armstrong, who I think is the most poetic of the astronauts.
