VOX.com has a page with “40 maps that explain the universe”. Photos and drawing plus text are there for your review. Some of the illustrations are really eye catching. For example:

Even a single comet is pretty darn big

This is the comet 67P/C-G — which the Philae probe landed on in November 2014 — superimposed on Los Angeles. In terms of space, the comet is absolutely tiny: just 3.5 miles wide.

Mayan Apocalypse And Earth’s Magnetic Field Reversal

Posted on December 14, 2012 | Leave a comment

NASA issued a bulletin that reviews the worried inquires people have made relative to the Mayan Apocalypse.  The “apocalypse” is that the Earth will end on 21 December 2012  when the Mayan 5125 year Long Count calendar ends. NASA said that a catastrophic celestial collision between Earth and the mythical planet Nibiru or  a disastrous crash with a comet are not going to happen.   Nibiru is supposed to be hiding behind the Sun. NASA says there is no planet hiding behind the Sun.  NASA also: “… rejected apocalyptic theories about unusual alignments of the planets, or that the Earth’s magnetic poles could suddenly “flip.”polarflips285px-Geomagnetic_polarity_late_Cenozoic
 
I am intrigued by the magnetic field flip. The North and South magnetic poles have flipped a number of times over the 5 billion year history of the Earth.  But generally scientists concur that the most recent flip occurred some 800,000+ years ago.  There are people that believe the magnetic poles have flipped much more recently.  One author, Robert Felix says, for example, that 11,000 years ago as well as 23,000 and 33,500 years ago, the polarity flipped.  He correlates these times with ice ages, eruptions of super volcanos and species mutations.
The legend on the chart to the right: Geomagnetic polarity during the late Cenozoic Era. Dark areas denote periods where the polarity matches today’s polarity, light areas denote periods where that polarity is reversed. (from Wikipedia–Click on chart to improve clarity)
