Observing 2012 DA14

Mostly the Universe stays unchanged for hundreds, thousands or even millions of years. There are some cases however when some things change really rapidly. Recently I observed one of these rapidly changing, transient phenomena, as asteroid called 2012 DA14. I work for Las Cumbres Observatory and we have been trying to observe this asteroid since 5 February.

DPS 2012: Future impact risks

Continuing my writeup of notes from last week's Division for Planetary Sciences meeting: presentations on the risks of future asteroid impacts. How much risk do we face, and what are the appropriate actions to take in the face of that risk?

Hunting Asteroids from a Field in Kansas

TPS Shoemaker NEO Grant Winner Gary Hug hunts near Earth objects from his back yard in Kansas. NPR's Morning Edition picked up on this fascinating story.

Meteorites hit Earth all the time, but they almost never score direct hits on human-built structures (or humans, for that matter). Once in a while, though, direct hits do happen, and it looks like this recent event in Poland was the real thing.

Close approach to Earth turns Apollo into Aten

Last week we got buzzed by a very small asteroid, something that happens fairly often. But there were several details that made the close approach of asteroid 2011 CQ1 worthy of note.

That's a bit of an overdramatic title, but it's true that the most efficient way for us to reduce the risk we face from asteroids that have a very small chance of hitting Earth in the future is to determine their orbits more precisely.
