“The dark matter seems to ‘know’ how the visible matter is distributed. They seem to conspire with each other such that the gravity of the visible matter at the characteristic radius of the dark halo is always the same,” said Dr. Benoit Famaey (Universities of Bonn and Strasbourg).

An artist’s concept illustration shows a quasar, or feeding black hole, similar to APM 08279+5255, where astronomers discovered huge amounts of water vapor. (NASA/ESA)
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)
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)

Mechanical oscillators translate an applied force into measurable 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)

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)
