Animated map of ~10,000 years of volcanic activity on Earth. ESRI, used by permission.
We live on a geologically-active planet. This, of course, isn't a shock to anyone but sometimes seeing just now active it is can be fascinating. ESRI put together a dynamic map (above) that captures worldwide volcanic activity over the past 10,000 years in just over 90 seconds. The planet lights up like a Christmas tree with all the eruptions of all sizes!

With a series of built-in rockets
on its underside, the ship could rise from the ground and touch back down again
vertically — the first of its kind.

When NASA launched Voyager 1 and Voyager 2 in the summer of 1977, its engineers were sending the spacecraft on specific missions. Originally, the space agency tasked the Voyagers with conducting close-up studies of Jupiter and Saturn. They would compile data on magnetic fields, the Sun’s influence, Saturn’s rings, a few large moons, and se ...read more
