Controllable electron flow in quantum wires

Princeton researchers have demonstrated a new way of making controllable "quantum wires" in the presence of a magnetic field, according to a new study published in Nature.

First evidence discovered of planet's destruction by its star

(Phys.org) -- The first evidence of a planet's destruction by its aging star has been discovered by an international team of astronomers. The evidence indicates that the missing planet was devoured as the star began expanding ...

Double engine for a nebula

(PhysOrg.com) -- The new image, showing a very rich field of stars towards the Carina arm of the Milky Way, is centred on the star HD 87643, a member of the exotic class of B[e] stars [1]. It is part of a set of observations ...

First quadruple asteroid system detected

A trio of researchers from the National Astronomical Research Institute of Thailand, Université de Lyon and Sorbonne Université, respectively, has made the first sighting of a quadruple asteroid system—an asteroid with ...

Swarm and Cluster missions get to the bottom of geomagnetic storms

The notion of living in a bubble is usually associated with negative connotations, but all life on Earth is dependent on the safe bubble created by our magnetic field. Understanding how the field is generated, how it protects ...

Fastest orbiting asteroid discovered

Using the powerful 570-megapixel Dark Energy Camera (DECam) in Chile, astronomers just ten days ago discovered an asteroid with the shortest orbital period of any known asteroid in the Solar System. The orbit of the approximately ...
