The anisotropies of the Cosmic microwave background (CMB) as observed by Planck. The CMB is a snapshot of the oldest light in our Universe, imprinted on the sky when the Universe was just 380 000 years old. It shows tiny temperature fluctuations that correspond to regions of slightly different densities, representing the seeds of all future structure: the stars and galaxies of today.

The two inset images show before-and-after images captured by NASA’s Hubble Space Telescope of Supernova 2012Z in the spiral galaxy NGC 1309. The white X at the top of the main image marks the location of the supernova in the galaxy. (Credit: NASA)

Nearly half of the respondents (48%) predicted that robots and AI will displace more jobs than they create over the coming decade. While that left a slim majority believing the impact of technology on employment will be neutral or positive. (Credit: Humanrobo/Wikimedia Commons)

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)

Japanese scientists recently published a paper that showed they could monitor neutrinos by putting a detector in the back of a van and parking it outside the reactor.

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)

Einstein was the first person to propose that ‘empty space’, which does not contain matter or radiation, is not actually empty and in fact has a residual energy. This empty space is also capable of creating more space from itself. (Credit: benmoat/Shutterstock)

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)
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. (Credit: NASA/SDO)

The 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. (Credit: Vienna University of Technology.)

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)

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. (D. A. Aguilar, Harvard-Smithsonian Center for Astrophysics)
