It's capable of peering inside atoms, yet at first glance the synchrotron appears to be little more than a white-walled...
Bombardier and ATR figured out how to quiet the beast, although the Q400's 15-second drone on takeoff caused a recent flyer to initially doubt the improved 76-seater. Once the plane is cruising, though, Bombardier's noise-and-vibration-reduction system (cousin to technology used in submarines) monitors...

It is probably more than 1.5 times the diameter of Earth and five times heavier. But unlike our world, which orbits a comfortable 92.9 million miles from the flames of the sun, 581c...
