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)

Professor Howard Milchberg. University physicists working in the Intense Laser Matter Interactions group have made two breakthroughs in recent months: One allows them to send high-powered lasers through atmosphere, and another uses this technology to collect weak signals from a distance.

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)

Sandia National Laboratories researchers Steve Plimpton, left, and Michael Gallis look at a projection of a model of the Russian MIR space station, which fell out of orbit several years ago and disintegrated, with the remains ending up at the bottom of the Indian Ocean. Using Sandia’s 3-D code SPARTA, the calculation is simulating an instance of the process of de-orbiting. (Credit: Randy Montoya)

Of course science has overturned earlier notions of how the Universe works. But sometimes, those rules are shown to be true so much and so often that when you come up with an idea that overthrows all of it, you’d better have iron-clad evidence of it. (Credit: Phil Plait, Paramount Pictures)

The work verifies theoretical models of the most likely way in which a quantum system will collapse, proving that the probable path can be predicted. This paves the way to actively controlling a quantum system in the future by steering it towards a certain outcome.(Credit: Irfan Siddiqi, UC Berkeley)

A perigee moon rises in Washington, DC, on March 19, 2011. A perigee moon is visible when the moon’s orbit position is at its closest point to Earth during a full moon phase. The full moon coincided with its closest approach to the Earth, 221,565 miles (356,575 km), making the so-called “super moon” look slightly larger than average. (Credit: JEWEL SAMAD/AFP/Getty Images)

The Rosetta spacecraft is scheduled to rendezvous with Comet 67P/Churyumov-Gerasimenko on Wednesday. If all goes according to plan, Rosetta will become the first probe ever to orbit a comet — and, in November, the first to drop a lander onto the surface of one of these icy wanderers. (Credit: ESA)
