Rolls-Royce expects remote-controlled cargo ships by 2020 http://engt.co/2912EDE
Autonomous ships wouldn't be that far behind.

Conservation of Momentum

This collision between two cherries depicts a fundamental property of classical mechanics: the conservation of momentum. Momentum is defined as the product of the mass and the velocity of an object. The conservation of momentum is implied by Newton's third law of motion, which states that for every action (force) there is an equal and opposite reaction. As the two cherries collide, the net momentum of the system is maintained as the cherries bounce backwards and the water droplets continue forwards.

Holy crap.
Skydivers channel their inner Harry Potter and Ron Weasley to score points in this high-flying fantasy game. Even Professor Snape would be impressed.

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.

Ferrofluid and Magnets

Ferrofluid is a liquid that becomes strongly magnetized in the presence of a magnetic field. It is typically composed of ferromagnetic (iron) particles suspended in oil. When exposed to a magnet, the particles align with the surrounding magnetic field. The complex orientation of the ferrofluid reveals the magnetic field around the two magnets.

Spacex will use Falcon Heavy for 2018 Mars Mission, then at least two Falcon Heavies in 2020 and then a Mars Colonial Transporter in 2022 http://nextbigfuture.com/2016/06/spacex-will-use-falcon-heavy-for-2018.html
Starting as soon as 2018, Musk’s SpaceX plans to fly an unmanned spacecraft to Mars. The unmanned flights would continue about every two years, timed for when Earth and Mars are closest in orbit, and, if everything goes accor...

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
