The Einstein ring, formed as light from a distant galaxy bends to glow around another object in the foreground, could help solve the universe’s mysteries.

A European space telescope captured a rare halo of light that circles a galaxy that is 590 million light-years away, which is close in cosmic estimates.

The $10 billion orbiting observatory will give astronomers a better sense of the near-Earth asteroid 2024 YR4's size and position.

The Webb telescope is well-suited to identify asteroid 2024 YR4's size. Webb views a type of light we can't see with the naked eye, called infrared. Infrared light is largely heat energy, allowing Webb to observe the heat from distant objects, whether they're planets or distant galaxies.
