Astronomers spot lightest exoplanet

The Hindu  

Astronomers may have discovered the lightest exoplanet ever seen, which appears just as a dot orbiting a young star. “Direct imaging of planets is an extremely challenging technique that requires the most advanced instruments, whether ground-based or in space,” said Julien Rameau from Institut de Planetologie et d’Astrophysique de Grenoble, France. The observations were made using infrared light and a technique called differential imaging, which improves the contrast between the planet and dazzling host star. The youth of this star, just 10 to 17 million years, leads astronomers to believe that this new planet probably formed within the gaseous and dusty disc that surrounds the star.
