There is no denying the awesome predictive power of Albert Einstein’s 1915 theory of gravity, general relativity — yet, the theory still has inconsistencies when it comes to calculating its effect on vast distances. And new research suggests these inconsistencies could be the result of a “cosmic glitch” in gravity itself. In the 109 years since it was first formulated, general relativity has remained our finest description of gravity on a galactic scale; time and again, experiments have confirmed its accuracy. This theory has also been used to predict aspects…

A new telescope billed as the world’s highest astronomical site is officially open for business. The Japanese University of Tokyo Atacama Observatory, or TAO, which was first conceptualized 26 years ago to study the evolution of galaxies and exoplanets, is perched on top of a tall mountain in the Chilean Andes at 5,640 meters (18,500 feet) above sea level. The facility’s altitude surpasses even the Atacama Large Millimeter Array, which is at an elevation of 5,050 meters (16,570 feet).  TAO is located on the summit of Atacama’s Cerro Chajnantor mountain,…

When we picture what’s in deep space, we often think of static images — colorful composites of distant objects like nebulas and galaxies, frozen in time. The reality is that everything is moving, and it’s moving fast. But given the vast distances involved, it’s hard for us to see that motion. NASA’s Chandra X-Ray Observatory, however, has been taking images for decades — long enough to compile timelapses that show the movement of deep space objects. And the team has just released two such “movies,” one of the iconic Crab…
