Why the F-117 Nighthawk isn't worried about radar detection

While the science behind the high bypass ratio engine in a 747 plane may seem complicated, the results are striking. It's capable of delivering over 70 percent more power than a standard engine.

Many scientists believe that black holes make sense in the realm of theoretical physics, but couldn't really exist in real life. Capturing an image of a black hole would change all that.

The F-117 Nighthawk is the ultimate stealth fighter, virtually undetectable to radar. But on a bombing raid over Belgrade in 1999, Colonel Dale Zelko is shocked to see two missiles locked in on his plane.

It's a tricky assignment: transporting a giant satellite dish 500 miles by lorry through narrow French roads, to the Belgian port of Antwerp. From there, it will be loaded onto a ship sailing to Chile.

The VSS Enterprise, which crashed on October 31, 2014, was powered by a new rocket motor with an experimental hybrid fuel. Did this cause the spacecraft to go down?
