Computer simulation of an object from the Late Heavy Bombardment period ~4 billion years ago striking a modern earth. It is inferred from craters on the moon that several objects perhaps as large as 100 km or more may have struck the earth during this time.

In the wake of last month's dramatic cosmic visitor lighting the dawn skies of Chelyabinsk, the U.S. House Committee on Science scheduled a long overdue hearing. Giant stony-rocky-snowball missiles, barreling near earth at miles per second; huge potential for damage and/or huge potential for resources?

Congressional leaders want to know if the government is doing all it can to spot potential space threats in time to possibly respond. NASA's Near Earth Objects Program, commonly called SpaceWatch, keeps an eye out for bodies approaching Earth and says it has identified nearly 1,400 potentially hazardous asteroids in space.  NASA was tracking the asteroid that passed by Earth on Feb. 15, it did not know about the meteor that caused the explosion over Russia.
Alas, the predicted and unrequited snow-pocalypse postponed what would have been a fascinating talk. For now I'll go ahead and guess a government drowning in a bathtub wrapped in a sequester isn't doing all it can on much of anything ...
  • The year 2013 is shaping up to be a banner year for another kind of visitor. The Bad Astronomer has a wrap up of those cometary neighbors including one that may be visible tonight!
  • Rep. Adam Schill (D-CA) opines on how the sequester will impact planetary science:
    It is my understanding that the planetary science program can withstand these cuts if they are of short duration, but if they continue, there will undoubtedly be consequences for the world's most amazing workforce and for science.
  • Just in case you needed an excuse for more red wine and chocolate, there it is.
  • I'm shocked, shocked I say!
    Global temperatures are warmer than at any time in at least 4,000 years, scientists reported Thursday, and over the coming decades are likely to surpass levels not seen on the planet since before the last ice age.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
