The spin of a molecule (orange) changes and deforms the nanotube (black) mounted between two electrodes (gold).

The dark hot spot in this false-color image from NASA's Cassini spacecraft is a window deep into Jupiter's atmosphere. All around it are layers of higher clouds, with colors indicating which layer of the atmosphere the clouds are in.

This image, taken by NASA’s Hubble Space Telescope, shows five moons orbiting the distant, icy dwarf planet Pluto. The green circle marks the newly discovered moon, designated P5, as photographed by Hubble’s Wide Field Camera 3 on July 7, 2012.

The interior bulk of a topological insulator is indeed an insulator, but electrons (spheres) move swiftly on the surface as if through a metal. They are spin-polarized, however, with their momenta (directional ribbons) and spins (arrows) locked together. Berkeley Lab researchers have discovered that the spin polarization of photoelectrons (arrowed sphere at upper right) emitted when the material is struck with high-energy photons (blue-green waves from left) is completely determined by the polarization of this incident light.

An artificial atomic nucleus made up of five charged calcium dimers is centered in an atomic-collapse electron cloud.

Two Different Aqueous Environments
This set of images compares rocks seen by NASA's Opportunity rover and Curiosity rover at two different parts of Mars. On the left is " Wopmay" rock, in Endurance Crater, Meridiani Planum, as studied by the Opportunity rover.

Maps of ozone concentrations over the Arctic come from the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite. The left image shows March 19, 2010, and the right shows the same date in 2011. March 2010 had relatively high ozone, while March 2011 has low levels.

The illustration on the left shows the variations of light intensity within a nanolaser. The figure on the right shows schematically a nanolaser with a metallic cavity, where the center red region confines electrons and the grey enclosure is a silver cavity. The blue layer on top is a substrate where the laser structure is grown. The orange-yellow color on top indicates the light emission. Research led by Arizona state University engineering professor Cun-Zheng Ning has produced nanolasers that can operate under a battery power at room temperatures – instead of only in refrigerated conditions – which opens the door to use of the lasers in many practical applications in modern electronics.
