Bad Astronomer is BADA55 or…
…How I Learned to Stop Worrying and Love Near Earth Objects
On November 8, 2011, you probably heard or read the news that an asteroid, 2005 YU55, flew between the Earth and the Moon. If you haven’t seen it yet, here is a little animation of images of the asteroid from NASA’s Jet Propulsion Laboratory. These pictures were taken when the object was getting close to the Earth on November 7, 2011. 2005 YU55 is about the size of an aircraft carrier.
Asteroids and other near Earth objects or NEOs are a concern because when they hit the Earth they do a lot of damage. Sometimes they cause catastrophic damage. For example, a giant asteroid is theorized to have hit the Earth causing so much devastation that it caused many of the life forms on Earth at the time, including the dinosaurs, to become extinct as a result. 2005 YU55 is just one of thousands of known near earth objects or NEOs that NASA’s Near Earth Object Program and other groups are watching closely.
Did I just scare you? Sorry.
But never fear, young Earthlings, for Phil Plait the Bad Astronomer is here!

Dr. Phil Plait is an astronomer and author of Death from the Skies!: These Are The Ways The World Will End. In this book he pretty much lists many of the ways that the universe in which we live can kill us and the odds of these events happening. Fortunately, the odds of these things happening in our lifetime are fairly low. (phew) Unfortunately, there is still a chance. So it’s a good idea for us to find things like near Earth objects that might some day hit the Earth and figure out a way to prevent them from turning our planet into a lifeless, molten ball of fiery lava. (whimper)
Phil Plait comes to the rescue by outlining a plan for preventing asteroid impacts in his awesome Ted Talk here.
Thanks, Bad Astronomer! You’ve saved the day!
Phil Plait writes the Bad Astronomy blog here. Almost every day, he points out new wonders of astronomy including gorgeous images of the universe and planetary aspects of the Earth.
By the way, ted.com is a site that is full of great, cutting-edge ideas in science and many other topics from the most brilliant people in a variety of fields. I encourage everyone to browse TED and enjoy the videos for their progressive and inspiring messages.
