Einstein’s right again: Star obeys relativity as it whirls around Milky Way’s black hole
News Brief: A 26-year-long observational campaign provides clear evidence of the effect that general relativity has on the motion of a star known as S2 as it boomerangs around the supermassive black hole at the center of our Milky Way galaxy. The redshift observations, made in infrared wavelengths using instruments on the European Southern Observatory’s…

Gravitational waves found! LIGO experiment watches two black holes smash together
A computer simulation shows two black holes shortly before they merge into one. (Credit: SXS) WASHINGTON, D.C. – After more than a decade of looking, scientists say they’ve detected the gravitational waves given off when two black holes merged into one bigger black hole. “Ladies and gentlemen, we have detected gravitational waves. We did it!” Caltech…

LISA Pathfinder blasts off to blaze a trail for relativity’s biggest test
The LISA Pathfinder probe lifts off from the European Space Agency’s spaceport in Kourou. (ESA photo) The LISA Pathfinder probe is heading for a vantage point a million miles from Earth to help look for gravitational waves and add a missing piece to the evidence for general relativity. The European Space Agency said an Italian-built Vega rocket sent…
