A rare Jupiter-sized planet AT2021uey b was found 3,200 light-years away using microlensing, a method based on Einstein's ...

Using gravitational microlensing, scientists have discovered a rare, large planet at the edge of the Milky Way. The planet is ...

An Einstein Ring was discovered by the European Space Agency's Euclid space telescope in September 2023.

Europe's Euclid space telescope has detected a rare ring of bright light around a nearby galaxy, astronomers have said. The halo, known as an "Einstein ring," encircles a galaxy 590 million light ...

An Einstein ring occurs when a distant galaxy is perfectly centered behind a closer one. The positioning causes its light to be distorted into a circle.

According to Albert Einstein’s general theory of relativity, light will bend around objects in space, so that they focus the light the way that a lens does.

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light. Albert Einstein's 1905 theory of ...

Scientists have discovered an incredible new "Einstein Ring"—a type of intergalactic mirage formed when a massive galaxy warps the fabric of spacetime like a colossal lens. The ring was spotted ...
