The Horsehead Nebula

The Horsehead Nebula (Barnard 33) is a dark nebula located in the constellation Orion just south of the star Alnitak. The nebula was discovered in 1888 by Scottish astronomer William Fleming on a photographic plate at the Harvard College Observatory. The nebula is approximately 1,500 light years away from the Earth and spans several light years. The red/pinkish glow originates from hydrogen gas behind the nebula that is ionized by the nearby star Sigma Orionis.

This imagery is a composite of photographs taken with the Hubble Space Telescope's Wide Field Camera 3 and the European Southern Observatory's Visible and Infrared Survey Telescope for Astronomy.

Cutting steel under an electron microscope

Unlike conventional light-based microscopes, electron microscopes use a beam of electrons to image a specimen. Because electrons are much smaller (~2.8 femtometers) than the wavelength of visible-light photons (400-800 nanometers), they are capable of producing much higher-resolution images.

Here a piece of steel is being cut by a titanium-coated carbide blade with a tip radius of approximately 200µm. As the piece of steel is pressed against the blade the rough upper layer is sheared away to produce a smooth surface.

This material (#Vantablack) is the darkest material ever created. It is so black it can fool your eyes that this piece of aluminum is smooth even though it is crumpled as you cant see the dents anymore after absorbing so much light. Pretty neat. http://www.popsci.com/only-one-artist-can-use-blackest-material-in-world

Mercedes-Benz's AMG division gave the SL-Class a powerful, hand-built engine.
It may be bigger than a typical roadster, but the 577-horsepower 2017 Mercedes-AMG SL63 feels light and quick in the turns.
