Best evidence yet for coronal heating theory

NASA's Solar Dynamics Observatory captured this image of what the sun looked like on April 23, 2013, at 1:30 p.m. EDT when the EUNIS mission launched. EUNIS focused on an active region of the sun, seen as bright loops in the upper right in this picture.

Scientists separate a particle from its properties

he study, carried out at the Institute Laue-Langevin (ILL) and published in Nature Communications, showed that in an interferometer a neutron's magnetic moment could be measured independently of the neutron itself, thereby marking the first experimental observation of a new quantum paradox known as the 'Cheshire Cat'. Pictured are Yuji Hasegawa, Tobias Denkmayr, Stephan Sponar, Hartmut Lemmel, and Hermann Geppert.

Exclusive: NASA’s Hubble finds ‘magnifying lens’ galaxy

In this image from the Hubble Space Telescope, a giant elliptical galaxy 9.6 billion light-years away appears as a red patch. The bluish dot and tadpole-shaped smear are the distorted and magnified shapes of a more distant spiral galaxy 10.7 billion light-years away. (Credit: NASA, ESA, K.-V.

Scientists in Scotland have created a working tractor beam

(Credit: iStock/360/Getty) — The Dundee tractor beam is not entirely dissimilar from those in “Star Wars” and “Star Trek,” in that it draws an object toward it without making physical contact. The device works by taking advantage of an acoustic wave’s natural push effect, called radiation pressure. (Photons also exert radiation pressure, which is part of the reason comet tails always point away from the sun.) What the Dundee team was able to demonstrate was an example of negative radiation pressure, otherwise known as pull. (Credit: iStock/360/Getty)

Giant asteroids reshaped Earth 4 billion years ago

The team says that during this 500 million year period the planet likely experienced three to seven impacts by objects more than 300 miles wide. There were also as many as four impacts by titanic space rocks more than 600 miles across. If there had been any life on the Earth, a 600 mile wide monster asteroid probably would have wiped it out. Surprisingly, these impacts are compatible with the existence of liquid water on the surface as early as 4.3 billion years ago. — The team says that during this 500 million year period the planet likely experienced three to seven impacts by objects more than 300 miles wide.

In 2013, Rutgers astronomer Rachel Somerville received the Dannie Heineman Prize in Astrophysics from the American Astronomical Society and the American Institute of Physics. The prize recognizes exceptional work by mid-career astronomers, citing her for providing fundamental insights into galaxy formation and evolution using modeling, simulations, and observations.

Mystery of the ‘Cheshire Cat’ of quantum physics solved: Scientists manage to separate a particle from its spin

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.

101 geysers identified on Saturn’s icy moon Enceladus

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.

Listening in on cosmic messages

Mapping signals on the sky can offer clues about where the signals originate. Pulsars (top) concentrate in the Milky Way, because most of the ones we see sit in our galaxy. Gamma bursts (middle) come from everywhere, which means they’re parked in other galaxies. Fast radio bursts (bottom) seem to mostly avoid our galgaxy, a hint that they may come from very far away.(Credits: Green Bank Telescope, West Virginia Univ; G. Fishman et al/BATSE, CGRO, NASA.; J.
