Black holes are one of Einstein’s most profound predictions in his general theory of relativity. They were first investigated as a mathematical consequence of the theory rather than as physically meaningful objects, but they quickly evolved into generic and sometimes unavoidable results of the gravitational collapse that produces a galaxy. In fact, most physicists believe … Read more
WASHINGTON – After traveling nearly 1.5 million kilometers, NASA’s James Webb Space Telescope arrived at its destination in space on Monday. Webb fired its onboard thrusters at 2 p.m. Eastern Time (1900 GMT) for nearly five minutes to complete the final postlaunch course correction to its trajectory, according to NASA. This mid-course correction burn inserted … Read more
WASHINGTON: The most powerful space telescope ever built completed a tricky two-week-long deployment phase Saturday, unfolding its final golden mirror panel, as it readies to study every phase of cosmic history. Engineering teams in the James Webb Space Telescope’s control room cheered as confirmation came back that its final wing was deployed and latched into … Read more
The James Webb Space Telescope, the most powerful space observatory ever built, is now tentatively set for launch on Christmas Day, after decades of waiting. An engineering marvel, it will help answer fundamental questions about the Universe, peering back in time 13 billion years. Here are five things to know.
