Two asteroids approach in the night

Map showing Ceres and Vesta as they approach each other closely this coming week. Both asteroids are near the easy-to-find star Zeta in Virgo not far from bright Mars. Although the asteroids appear very close together in the sky, they’re really about 51 million miles apart with Vesta in the foreground. (Credit: Chris Marriott’s SkyMap)

Novel Technique to Measure Quantum-Optical Effect in Light from the Sun

By filtering light from the sun, CQT researchers have made a strong detection of a quantum effect known as 'photon bunching' in its light. This is a hallmark of the sun radiating like a black body. (Credit: NASA/SDO)

Researchers detect tiniest of force ever measured

Mechanical oscillators translate an applied force into measureable mechanical motion. The Standard Quantum Limit is imposed by the Heisenberg uncertainty principle, in which the measurement itself perturbs the motion of the oscillator, a phenomenon known as “quantum back-action.” (Credit: Kevin Gutowski)

The Smallest Black Hole in the Universe (Synopsis)

A binary system containing a stellar-mass black hole called IGR J17091. The strong gravity of the black hole, on the left, is pulling gas away from a companion star on the right. This gas forms a disk of hot gas around the black hole, and the wind is driven off this disk(Credit: NASA/CXC/M.Weiss)

NASA: Sun’s corona much larger than previously thought

Scientists used these observations of the sun's atmosphere (the bright light of the sun itself is blocked by the black circle at the middle) from NASA's Solar Terrestrial Relations Observatory on Aug. 5, 2007, to define the outer limits of the solar atmosphere, the corona. (Credit: NASA/STEREO)

Clumped galaxies give General Relativity its toughest test yet

More than 600 000 galaxies from the BOSS survey were utilized to measure the strength of gravitational interactions of galaxies extremely far away from each other. This is a visual representation of that measurement; the amount that the circles are distorted, or squashed from perfect concentric rings, indicates the velocity that galaxies are falling towards each other and hence the strength of the gravitational interactions. Credit: BOSS/U. Portsmouth
