India, July 17 -- Astronomers have discovered a giant planet outside the solar system, known as an exoplanet, hidden within one of the most intensely studied planetary systems in the Milky Way galaxy.

Using NASA's James Webb Space Telescope, astronomers discovered Beta Pictoris d orbiting the nearby star Beta Pictoris, a planetary system that scientists have been studying for decades. The system was already known to host two giant planets: Beta Pictoris b, one of the first exoplanets ever to be directly imaged, and Beta Pictoris c.

The discovery of Beta Pictoris d marks a significant milestone because, unlike Beta Pictoris b and c, it was not identified as a bright point of light. Instead, astronomers detected the unique chemical finger...
