This story begins not in a galaxy far away, but at a Milwaukee rummage sale a few years ago. Tom Lynch paid $10 for an odd hunk of metal he figured might be copper or bronze with potential salvage value.
He had no idea it had dropped from space into the Arizona desert some 50,000 years ago.

"For the last two years, it kept my grandson's basketball hoop from blowing over in the yard. It weighs 50 pounds" - Lynch, a retired foundry and General Motors worker who lives in South Milwaukee.

Recently, he saw a show about meteorites on the Travel Channel and realised that's probably what he had. It was curious, he thought, that the thing never oxidised in the weather. Following advice from the TV show, he held a magnet up to the object and it stuck.
He took his 4.6 billion-year-old find to the Milwaukee Public Museum and then to Chicago's Field Museum last month. The scientists got excited. Yes, they said, it's a meteorite.

As holes go, the one off Interstate 40 a short drive from Flagstaff is a whopper. From a distance it's a mere blip on the horizon, its rim rising 150 feet above the flat scrubland that dominates much of northern Arizona. But that rim hides a yawning expanse - more bowl than hole, really - 4,100 feet across and 550 feet deep. If they played a football game in the bottom, the sides could hold two million fans, give or take a luxury box or two.
But what really raises this hole above humdrum is how it was created. About 50,000 years ago, a 150-foot lump of iron and nickel, a renegade from the asteroid belt between Mars and Jupiter, sliced through the sky out of the northeast at seven miles per second. When it hit it tore up the landscape in an instant, excavating several hundred million tons of dirt and rock and flipping layers of sandstone like pancakes.

Canyon Diablo Meteorite
Iron, coarse octahedrite
Meteor Crater, Coconino County, Arizona

This is a palm-sized meteorite. While it stands in a variety of positions, a scoop on the reverse was most probably created by the ejection of a graphite nodule. With softened ridges separating its numerous faces, this is a lively fragment of the asteroid belt-like all iron meteorites- recovered at Canyon Diablo ("The Devil's Canyon"), the most famous American meteorite impact and the best preserved meteorite crater on Earth. 58 x 61 x 52 mm (2.25 x 2.5 x 2 inches) and 489 grams (1 pound).

Meteor Crater was formed in 10 seconds. About 50,000 years ago, a meteor struck the Earth, blasting a hole into the landscape about 700 feet deep and three-quarters of a mile wide. More than 175 million tons of rock were thrown into the air. Hurricane-force winds blew in all directions.
You can see the abyss left by this impact at a museum about 35 miles east of Flagstaff.

The land near Flagstaff, AZ thats home to Meteor Crater is also known as Barringer Crater, formerly Canyon Diablo Crater. Daniel Barringers Standard Iron Company purchased the land in 1903 and members of Barringers family, who are on the board at The Franklin Institute, donated this gargantuan sample to the museum.
