For those interested, there's going to be a total lunar eclipse on Monday night.  Best viewing in the US will be around 1:15am eastern.

YES! .. great success.

A new website lets astronomers - and anyone who likes to watch stuff blow up - calculate the damage a comet or asteroid would cause if it hit Earth.
The interactive website, called Impact: Earth! (available at www.purdue.edu/impactearth), is scientifically accurate enough to be used by the Department of Homeland Security and NASA, but user-friendly enough for elementary school students, according to the researchers who developed it.

I think this thing is broken.  I put in a strike on land by a 10km wide asteroid made of solid depleted uranium and it said there would be survivable areas.

hmm, how fast? Here is the math for those more gifted than me. http://www.purdue.edu/impactearth/Conte … tation.pdf

I put the speed as high as it would go with a 90 degree and 45 degree impacts.  The location was 5000km away from impact, but I'd expect a blast of over a trillion times the power of an average atomic bomb to level pretty much everything on earth.  Instead this thing told me that there were places where the pressure would go unnoticed and the noise would be at about the level of highway traffic.

I used to enjoy the Bad Astronomy blog by Phil Plait, nowadays it seems he uses it as his own personal soapbox for the same old tired American political bullshit, nonsense about his personal life and generally everything else except what it should be about. This is what I notice about alot of people when they become successful with their blogs, they quickly diversify from what made them successful and end up becoming a diluted mess.

• 10: Every black hole may hold a hidden universe Our universe could be inside a black hole – if an analysis based on a modified version of Einstein's general relativity proves to be correct.
• 9: Starship pilots: speed kills, especially warp speed Star Trek fans, prepare to be disappointed: travelling near light speed is as lethal as standing in front of the Large Hadron Collider beam at full power.
• 8: New black hole simulator uses real star data A new interactive program that uses data from more than 100,000 stars reveals the spectacular light show you'd see if you wandered close to a black hole.

• 7: Neptune may have eaten a planet and stolen its moon The brutal deed could explain mysterious heat radiating from the icy planet and the tilted, backwards orbit of its moon Triton.
• 6: 'Space diver' to attempt first supersonic freefall A daredevil who parachutes from skyscrapers announced in January that he would try to smash the nearly 50-year-old record for the highest-ever jump, becoming the first person to go supersonic in freefall. But in October, his corporate sponsor, Red Bull, stopped work on the project, citing a multi-million-dollar lawsuit by an entrepreneur who claimed rights to the idea.
• 5: Jupiter loses a stripe A dark band on the giant planet's southern hemisphere vanished in May. But by November, it was making a comeback (see bright spots in inset, taken on 18 November). "The reason Jupiter seemed to 'lose' this band – camouflaging itself among the surrounding white bands – is that the usual downwelling winds that are dry and keep the region clear of [white] clouds died down," says NASA's Glenn Orton.
• 4: Rethinking Einstein The end of space-time Physicists struggling to reconcile gravity with quantum mechanics have hailed a theory – inspired by pencil lead – that could make it all very simple.
• 3: Hints of life found on Saturn moon In 2005, researchers predicted two potential signatures of life on Saturn's moon Titan – now both have been seen. But there are non-biological explanations for the observations, and several missions to Titan's surface would be needed to find unambiguous evidence for life there.
• 2: What's wrong with the sun? Right now our nearest star should be flaring up as never before. But instead it's eerily calm – and we need to find out why.
• 1: Mysterious radio waves emitted from nearby galaxy There is something strange in the cosmic neighbourhood. An unknown object in the nearby galaxy M82 has started sending out radio waves, and the emission does not look like anything seen in the universe before.
