This view of the “belly” and part of the “head” of comet 67P/Churyumov-Gerasimenko indicates several morphologically different regions.
The comet has areas dominated by cliffs, depressions, craters, boulders and even parallel grooves. While some of these areas appear to be quiet, others seem to be shaped by the comet’s activity, in which grains emitted from below the surface fall back to the ground in the nearby area.

Indeed, whether or not one particular country is slightly misplaced isn’t really the point. It’s that when we look back 300 million years into our geological history, it seems absurd to think that we somehow ended up where we are today–not from the standpoint of nature but from the standpoint of human nature.

The map above shows land surface temperature anomalies in North America for January 1 to 7, 2014. Data was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.
The map depicts temperatures for this period compared to the 2001–2010 average for the same week. Areas with warmer than average temperatures are shown in red, near-normal temperatures are white, and areas that were cooler than the base period are shown in blue.

During roughly this same period, Australia suffered an intense heatwave that brought record-breaking temperatures, while in South America, Argentinians faced a two-week heatwave that boosted temperatures more than 15°C (27°F) above average in some areas, causing widespread power and water shortages.

Created by cartographer Joan Blaeu, the chart is based partly on an exploratory voyage by the Dutch East India Company and also on Abel Tasman’s sightings in 1642.
Believed to have been mostly used as a wall decoration in a grand home or palace, the map was found in a storage unit in Sweden in 2010 and offered for sale in Stockholm for about $10,000.
