How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies these rocky, or "terrestrial," worlds are far more common than was suspected ...

The sun is not a mirror, but it is a lens. And we understand it's a lens through the magic of gravity. When Einstein developed general relativity, he realized that gravity can strongly bend the ...

Physicist Melvin Vopson proposes gravity might emerge from cosmic information processing, hinting the universe runs on a ...

Scientists are using cosmic distortions in light to test a bold idea: that the Universe might not be as symmetrical as we’ve ...

The solar gravitation lens (SGL) has much potential as a telescope. This point in space, located about 650 AU away from the ...

A new study released on Thursday describes a search for what are called "microlensing" events, where a planet acts as a ...

The school-bus-sized observatory launched on April 24, 1990 and overcame early setbacks to become one of the most scientifically productive instruments in history. From its vantage point 320 miles ...

Astronomers have caught a black hole far from the center of its galaxy ripping a star to shreds — offering for the first time ...
