Star orbiting massive black hole lends support to Einstein's theory

Observations of light coming from a star zipping in orbit around the humongous black hole at the center of our galaxy have provided fresh evidence backing Albert Einstein's 1915 theory of general relativity, astronomers said on Thursday. Researchers studied a star called S0-2, boasting a mass roughly 10 times larger than the sun, as it travels in an elliptical orbit lasting 16 years around the supermassive black hole called Sagittarius A* residing at the center of the Milky Way 26,000 light-years from Earth.

Giant dinosaur bone found in southwestern France

The thigh bone of a giant dinosaur was found this week by French paleontologists at an excavation site in southwestern France where remains of some of the largest animals that ever lived on land have been dug up since 2010. The two-meter long femur at the Angeac-Charente site is thought to have belonged to a sauropod, herbivorous dinosaurs with long necks and tails which were widespread in the late Jurassic era, over 140 million years ago.
