Two models of the dark matter distribution in the halo of a galaxy like the Milky Way, separated by the white line are shown. The colors represent the density of dark matter, with red indicating high-density and blue indicating low-density. On the left is a simulation of how non-interacting cold dark matter produces an abundance of smaller satellite galaxies. On the right the simulation shows the situation when the interaction of dark matter with other particles reduces the number of satellite galaxies we expect to observe around the Milky Way.

Cassini spied just as many regular, faint clumps in Saturn’s narrow F ring (the outermost, thin ring), like those pictured here, as Voyager did. But it saw hardly any of the long, bright clumps that were common in Voyager images. (Credit: NASA/JPL-Caltech/SSI)

Oscillations of photons create an image of frozen light. At first, photons in the experiment flow easily between two superconducting sites, producing the large waves shown at left. After a time, the scientists cause the light to “freeze,” trapping the photons in place. Fast oscillations on the right of the image are evidence of the new trapped behavior.

Erlangen-based physicists have sent bright pulses in sensitive quantum states through the window of a technical services room on the roof of the Max Planck Institute for the Science of Light to a building of the University Erlangen-Nürnberg. These types of light flashes are easy to receive even when the sun is shining brightly, unlike the signals of individual photons used to date. (Credit: MPI for the Science of Light)

The gravity of a black hole swallows the matter around it. The link between tensor networks and quantum entanglement may prove useful in studying the physics of black holes, some physicists propose. (Credit: M. Weiss, Chandra X -ray Center/NASA)

Square, cage-shaped molecules called diamondoids (left) linked to soccer-ball shaped buckyballs (right) create a new molecule called a buckydiamondoid, center, in this illustration. These new hybrid molecules may be useful for developing molecular electronic devices in the future. (Credit: Manoharan Lab/Stanford University)

Machines have surpassed humans in physical strength, speed and stamina. What if they surpassed human intellect as well? Science fiction movies have explored this question. In the classic “2001: A Space Odyssey,” astronaut David Bowman, played by Keir Dullea, struggles for control of the spacecraft against the sentient computer HAL 9000.

NASA hopes to add precious years of functional life to satellites and expand options for operators who face unexpected emergencies, tougher economic demand and aging fleets. (Credit: Bob Granath, Kt-Imaging)

Andromeda is twice as massive as the Milky Way. Scientists say that Andromeda has twice the mass, made of dark matter, than the Milky Way. (Credit: Phil Plait)

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)
