Fibers stick to a hard surface (top) and then can be removed to create a hollow ring (bottom left). Bottom right shows a closeup of the tiny fibers.

In one of the most remote lakes of Antarctica, nearly 65 feet beneath the icy surface, scientists from NASA, the Desert Research Institute (DRI) in Reno, Nev., the University of Illinois at Chicago, and nine other institutions, have uncovered a community of bacteria. This discovery of life existing in one of Earth's darkest, saltiest and coldest habitats is significant because it helps increase our limited knowledge of how life can sustain itself in these extreme environments on our own planet and beyond.

Spectacular jets powered by the gravitational energy of a super massive black hole in the core of the elliptical galaxy Hercules A illustrate the combined imaging power of two of astronomy's cutting-edge tools, the Hubble Space Telescope's Wide Field Camera 3, and the recently upgraded Karl G. Jansky Very Large Array (VLA) radio telescope in New Mexico.

The midnight sun casts a golden glow on an iceberg and its reflection in Disko Bay, Greenland. Much of Greenland's annual ice mass loss occurs through calving of icebergs such as this.

This image from NASA's Cassini mission was taken on Nov. 27, 2012, with Cassini's narrow-angle camera.

The possible quantum states of a chain of particles can be represented as points in space, with lines connecting states that can be swapped with no change in the chain's total energy. MIT researchers and their colleagues showed that such networks are densely interconnected, with heavily trafficked pathways between points.

Observations made with NIST's Electron Beam Ion Trap indicate that in ions with a strongly positive charge, electrons can behave in ways inconsistent with quantum electrodynamics (QED) theory, which describes electromagnetism. While more experiments are needed, the data could imply that some aspects of QED theory require revision.
