Atomic fireballs: the man with the pics

tumbler_snapper_bombThought ya’ll might get a kick of the old sensawunda out of these “rapatronic” high-speed photos of nuclear bombs exploding:

The exposures were often as short as 10 nanoseconds, and each Rapatronic camera would take exactly one photograph.

A bank of four to ten or more such cameras were arranged at tests to record different moments of early fireball growth.

They provide technical information about the device’s disassembly.

Some really awesome images captured here. More on rapatronics here.

First image of Mercury from Messenger mission transmitted

The first images ever of this side of the first planetMessenger, a NASA probe launched towards Mercury, has transmitted the first image of the unseen side of the first planet in our solar system, Mercury. Whilst Mariner 10 did pass Mercury 3 times in the seventies, it never saw this side due to the strange relationship between Mercury’s spin and orbit around the sun. The image is very good quality, with a lighter region in the top right corner believed to be the area of the planet that comes closest to the scorching heat of the sun.
