Astronomers image lowest-mass exoplanet around a sun-like star

Using infrared data from the Subaru Telescope in Hawaii, an international team of astronomers has imaged a giant planet around the bright star GJ 504. Several times the mass of Jupiter and similar in size, the new world, dubbed GJ 504b, is the lowest-mass planet ever detected around a star like the sun using direct imaging techniques.

Planets found in stellar cluster

Astronomers have, for the first time, spotted planets orbiting sun-like stars in a crowded cluster - the best evidence yet that planets can form in dense stellar environments.
