How Bright Will Comet ISON Be? A Look Back to 1680
At the end of next month, Comet ISON is expected to be at its brightest, when it is nearest to the Sun. Still, no one knows exactly what it will look like.
At the end of next month, Comet ISON is expected to be at its brightest, when it is nearest to the Sun. Still, no one knows exactly what it will look like. And so, to provide a hint, NASA dug up the image above, which is Comet Kirch, the Great Comet of 1680 that is pictured above a crowd of Rotterdam in the Netherlands. Some people in the crowd are holding cross-staffs, a primitive angle measuring device.
This image is a painting by Lieve Versheier, and it represents the moment when Comet Kirch was also nearest to the Sun.

New research links urban planning and political polarization.
- Canadian researchers find that excessive reliance on cars changes political views.
- Decades of car-centric urban planning normalized unsustainable lifestyles.
- People who prefer personal comfort elect politicians who represent such views.
Progressive America would be half as big, but twice as populated as its conservative twin.
- America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
- Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
- Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America
Science and the squishiness of the human mind. The joys of wearing whatever the hell you want, and so much more.
- Why can't we have a human-sized cat tree?
- What would happen if you got a spoonful of a neutron star?
- Why do we insist on dividing our wonderfully complex selves into boring little boxes
