Galaxy’s Black Hole Has a Surprisingly Small Appetite

For years, scientists have observed that the black hole at the center of our galaxy has a surprisingly small appetite.

Chandra Images Sgr A* Capture Hot Gas Ejected by Nearby Stars and Funnel It In

Astronomers using NASA's Chandra X-ray Observatory have taken a major step in explaining why material around the giant black hole at the center of the Milky Way Galaxy is extraordinarily faint in X-rays. This discovery holds important implications for understanding black holes.

Physicists Simulate Cosmic Microwave Background Radiation Following the Big Bang

Physicists have reproduced a pattern resembling the cosmic microwave background radiation in a laboratory simulation of the Big Bang, using ultracold cesium atoms in a vacuum chamber at the University of Chicago.

Modified Newtonian Dynamics Predicts Velocity Dispersion in Andromeda’s Dwarf Satellite Galaxies

A modified law of gravity correctly predicted, in advance of the observations, the velocity dispersion—the average speed of stars within a galaxy relative to each other—in 10 dwarf satellite galaxies of the Milky Way’s giant neighbor Andromeda.

Gas Cloud in Milky Way Galaxy Splits Images of Quasar

For the first time, astronomers have seen the image of a distant quasar split into multiple images by the effects of a cloud of ionized gas in our own Milky Way Galaxy. Such events were predicted as early as 1970, but the first evidence for one now has come from the National Science Foundation's Very Long Baseline Array (VLBA) radio telescope system.

Oldest Solar Twin Identified and Studied Using ESO’s Very Large Telescope

An international team led by astronomers in Brazil has used ESO’s Very Large Telescope to identify and study the oldest solar twin known to date. Located 250 light-years from Earth, the star HIP 102152 is more like the Sun than any other solar twin — except that it is nearly four billion years older.

Nobel Laureate Astrophysicist to Present Lectures at Brookhaven Lab

Nobel Laureate Adam Riess, a distinguished astrophysicist at The Johns Hopkins University and Space Telescope Science Institute, will present two George B. Pegram Lectures at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory in Berkner Hall on Monday, Sept. 23, at 4 p.m. and Tuesday, Sept. 24, at 11 a.m.

Researchers Demonstrate Dynamical Stabilization of Non-Equilibrium Many-Body Quantum System

A simple pendulum has two equilibrium points: hanging in the “down” position and perfectly inverted in the “up” position. While the “down” position is a stable equilibrium, the inverted position is definitely not stable. Any infinitesimal deviation from perfectly inverted is enough to cause the pendulum to eventually swing down.

Spitzer Space Telescope’s 10th Anniversary Celebrated at Lockheed Martin

Ten years ago, NASA's Spitzer Space Telescope – built, integrated and tested at Lockheed Martin [NYSE: LMT] Space Systems in Sunnyvale – roared into space from the Kennedy Space Center in Florida, carrying the observatory into an Earth-trailing orbit around the sun.

ORNL Welcomes Leaders in the Neutron Scattering Field

Oak Ridge National Laboratory's Neutron Sciences Directorate (NScD), home organization for the Department of Energy's Spallation Neutron Source (SNS) and High Flux Isotope Reactor (HFIR), has filled two high-level administrative positions with leaders in the neutron scattering field.
