University of Warwick researchers explain mystery of the loneliest supernovas. Compact binary star systems that have been thrown far from their host galaxy when one star of that pair became a neutron star, go through a second trauma when the remaining white dwarf star is eventually pulled onto the neutron star.

While time travel may be theoretically possible, there are unfortunately several drawbacks to the researchers’ TARDIS concept. In order to function, it requires the use of exotic matter, which has yet to be shown to exist in our universe. Time travel would also have to violate classical mechanics, and in order to move in anything other than a circular direction in both time and space, more than one TARDIS curve would need to be constructed, raising the possibility of exiting the time vortex into a universe of anti-matter.

Do you see a duck? On August 6, millions of miles away from Earth, the firing of a rocket thruster signalled the end of a decade-long journey by a European spacecraft to reach its ultimate target – the ‘duck’ comet. (Credit: ESA/Rosetta/MPS)

A typical magnifying glass works by bending light (i.e. refraction) to a focus point, in this case your eye. In a similar way, gravitational lensing also works by bending light, but in this case it is mass from another galaxy bending the light. This galaxy that extends far into space causes light rays passing near and through its gravitational field to bend and again refocus onto a particular location. The more massive and dense the matter, the more bending and refracting. (Credit: Flickr, Hubble Heritage)

Chu says worker feedback from the trial has been mostly positive. Testers were pleased that the exoskeleton let them lift heavy objects repeatedly without strain, but everyone also wanted it to move faster and be able to cope with heavier loads. (Credit: Daewoo)

This is a schematic of the process to localize NV centers in 3-D. The researchers blasted carbon ions through holes to create vacancies and heated the diamond to make the vacancies mobile within the crystal. NV centers could form in the nitrogen-doped layer below where the holes were placed. (Credit: F.J. Heremans and D. Awschalom/U. Chicago and K. Ohno/UCSB)
Scientists have observed for the first time a weird quantum phenomenon known as the ‘Cheshire Cat’ effect (illustration shown). The ‘cat’ in question was a subatomic neutron particle, and the ghostly ‘grin’ the particle’s magnetic moment, which describes the strength of its coupling to an external magnetic field.

This graphic shows a 3-D model of 98 geysers whose source locations and tilts were found in a Cassini imaging survey of Enceladus’ south polar terrain by the method of triangulation. While some jets are strongly tilted, it is clear the jets on average lie in four distinct “planes” that are normal to the surface at their source location. (Credit: NASA)

Figure 1: Nucleons (protons and neutrons) are made up of quarks (colored spheres) and have an orientation called spin (indicated by up and down arrows). The spin–orbit force is the interaction between two orbiting nucleons, resulting in a potential well (center) that holds them together.
