Gravitational lensing is a phenomenon in which massive objects, such as galaxies or black holes, bend and magnify light from distant sources, acting as natural cosmic telescopes that allow astronomers to observe otherwise faint or hidden objects in the universe.

Beta Pictoris, a young star system located approximately 63 light-years from Earth, is renowned for its circumstellar disk of dust and gas, offering astronomers a prime opportunity to study planetary formation in action.

In a surprising discovery, astronomers using the Hubble Space Telescope uncovered a concentration of small black holes lurking in the core of the globular cluster NGC 6397.
