The World’s Smallest Snowman stands less than 3 microns tall. The snowman was fabricated from three 0.9 micron silica spheres stacked with the use of electron beam lithography. The eyes and mouth were cut with a focused ion beam while the arms and nose were sculpted with platinum.

Lightning Appreciation Post:
There are nearly 500 lightning strikes every second around the world.
Only about 100 of these strike the earth, the others are between and within the clouds themselves.
Lightning is very visible from space (last gif from Astronaut Reid Wiseman)
Besides regular storms (thunder storms, hurricanes, etc.) lightning can be found in volcanoes (gif 3) and even intense forest fires.
In conclusion: nature is fucking awesome!

On Earth, the change of the seasons can be marked by the length of the shadows cast by the sun. This approach also works on Saturn, where the shadow of the massive planet grows shorter each day.
A new photo from the Cassini probe shows the shadow of Saturn blanketing a large section of the planet’s ring system. But back in 2007, Cassini images showed Saturn’s shadow stretching well beyond the edge of the rings. The shortening of the planet’s shadow will continue as Saturn approaches a solstice in May 2017.
