“This is a long-standing, really neat experimental idea,” says Paul Lett, of the National Institute of Standards and Technology in GaithersburgLett, “Now we have to see whether or not it will lead to something practical, or will remain just a clever demonstration of quantum mechanics.”(CreditBarreto-Lemos, Vergano)

The Borexino neutrino detector uses a sphere filled with liquid scintillator that emits light when excited. This inner vessel is surrounded by layers of shielding and by about 2,000 photomultiplier tubes to detect the light flashes.(Credit: Borexino Collaboration)

MOLECULAR MODEL In the molecular model, quark-antiquark pairs form two color-neutral mesons that become weakly linked as a molecule.DIQUARK MODEL The particles form quark-quark and antiquark-antiquark pairs, which are forced to combine to balance their color charges.

A computer model shows one scenario for how light is spread through the early universe on vast scales (more than 50 million light years across). Astronomers will soon know whether or not these kinds of computer models give an accurate portrayal of light in the real cosmos. (Credit: Andrew Pontzen/Fabio Governato)

What’s that dot on the Sun? If you look closely, it is almost perfectly round. The dot is the result of an unusual type of solar eclipse that occurred in 2006. Usually it is the Earth’s Moon that eclipses the Sun. This time, the planet Mercury took a turn. (Credit: D. Cortner, NASA, K. Schmidt)
“Maybe we will see how galaxies are magnetically connected to intergalactic space. This is a key experiment in preparation for the planned Square Kilometre Array (SKA) that should tell us how cosmic magnetic fields are generated,” says Rainer Beck, lead astronomer with the Max Planck Institute.

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.

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)
