The tractor beam, which is a staple of science fiction like 'Star Wars' and 'Star Trek' that was used to grab spaceships and other things remotely, is going to enter the realm of reality. On Tuesday, researchers said that they have created a tractor beam that takes help from high-amplitude sound waves to levitate, move and rotate tiny objects without coming in touch with them.

The researchers have envisioned medical and other applications for the device. Study's lead author Asier Marzo of Britain's University of Bristol and Spain's Public University of Navarre said that being a mechanical wave, sound can exert large forces on objects. While giving an example, Marzo said that just recall once, the last time you were in a concert and your chest started vibrating with the music.

NASA's Jet Propulsion Laboratory scientists and engineers are making Cassini spacecraft ready for a daring run across a plume ejected from the surface of Enceladus, the sixth-largest moon of Saturn.

During the pass, the spacecraft will reach speed of about 19,000 mph. With the help of this pass, scientists will be able to better understand the dynamics present in the ocean on far away icy world.

Cassini will sample water ejecting up from geysers spraying up from the Saturn's moon on Wednesday, October 28.
