Uranus size exoplanet discovered using gravitational microlensing

Astronomers have confirmed the existence of a Uranus-sized exoplanet orbiting far from its central star, discovered through a technique called gravitational microlensing.

Uranus size planet discovered

NASA’s Hubble Space Telescope and the W M Keck Observatory in Hawaii made independent confirmations of the exoplanet orbiting far from its central star. Microlensing technique can find distant and colder planets in long-period orbits that other methods cannot detect. Microlensing occurs when a foreground star amplifies the light of a background star that momentarily aligns with it. If the foreground star has planets, then the planets may also amplify the light of the background star, but for a much shorter period of time than their host star.
