As you probably have heard, today, February 15th, a 150-foot (45 meter) asteroid is whizzing by the Earth a hair’s breath from the surface. Missing us by only 14,000 miles, well within the 22,300 mile orbit of the Geostationary satellites that orbit around the Earth’s equator.
I wanted to put this in perspective for you with some of the chilling and fascinating facts:
This is approximately the same size as the asteroid that hit the Earth in Russia in Siberia (the “Tunguska Event”) on June 30th 1908.
That impact was equivalent to 1,000 Hiroshima nuclear bombs & knocked down 80 million trees down over an area covering 2,150 square kilometers (830 sq mi).
Had it hit near a population center it would have killed millions of people.

A parade of media reports this week name Penny Pritzker as Obamas prime choice for Secretary of Commerce. No longer will criminal bankers have to lobby the administration – because now they’ll have one of their own in the Cabinet.We never heard of this guy Barack Obama until 2004. Less than three years before taking the presidency, he was in the Illinois state senate, a swamp of scammers, backhanders, and party machine tools – not a stellar launch pad for the White House. And then, one day, state Sen. Barack Obama was visited by his fairy godmother. Her name is Penny Pritzker.

This story begins with a group of people who are expert at looking: the professional searchers known as radiologists.
“If you watch radiologists do what they do, [you’re] absolutely convinced that they are like superhuman,” says Trafton Drew, an attention researcher at Harvard Medical School.
About three years ago, Drew started visiting the dark, cavelike “reading rooms” where radiologists do their work. For hours he would stand watching them, in awe that they could so easily see in the images before them things that to Drew were simply invisible.
“These tiny little nodules that I can’t even see when people point to them — they’re just in a different world when it comes to finding this very, very hard-to-find thing,” Drew says.
In the Invisible Gorilla study, subjects have to count how many times the people in white shirts pass the basketball. By focusing their attention on the ball, they tend to not notice when a guy in a gorilla suit shows up.

But radiologists still sometimes fail to see important things, and Drew wanted to understand more. Because of his line of work, he was naturally familiar with one of the most famous studies in the field of attention research, the Invisible Gorilla study.
