Images from Mars.


The European Space Agency launched the Rosetta space probe {wiki} in 2004 to study the comet 67P/Churyumov-Gerasimenko. It should reach the comet by 2014. Rosetta has just passed Mars, and sent back some beautiful photographs.

In the lead image above, an orange (red), green and near-UV colour filter composite image of Mars is shown; the UV channel (the blue color) has been enhanced. The enhanced UV signal clearly shows the presence of the cloud system covering most of the Martian disk.

His dictionary count is a bit off.

If you included medical/science terms it's over a million for the count in English. But current usage has us at 250k, not counting derivatives and historical words. If you include the full lexicon it's somewhere above 750k.
