A new network of surveillance cameras will track meteorites as they enter Earth’s atmosphere, helping meteor-hunters track where the rocks land and where they came from.
So far, there are only three cameras, but astronomers hope to add a dozen more in schools and science centers, eventually broadening the All-Sky Fireball Network to the entire country. The system consists of smart black-and-white cameras that record the entire night sky, fish-eye-like.
As tonight bleeds into tomorrow morning, the earth will be hurtling through a long skein of dust and rocks. Lucky for us, the result of our bombardment will not be annihilation, but rather one of the richest natural light shows of the year—the Perseid meteor shower. Here's how to watch.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
