Einstein Ring

• The ESA's Euclid space telescope has captured a rare Einstein ring around galaxy NGC 6505, located 590 million light years away.
• This phenomenon, caused by gravitational lensing, occurs when a massive galaxy distorts light from a more distant galaxy, offering valuable insights into dark matter and the universe's expansion.
• The discovery, described as extra ordinary, highlights Euclid's capabilities in studying deep space phenomenon.
