Daniel CleryAstronomers know of thousands of planets around other stars, yet only a handful have been imaged directly. The existence of the rest is inferred by how they affect their stars.Now the world’s largest optical telescope has directly spied a new planetary system—the first time more than one planet has been imaged around a star like our Sun.
Astronomers used the European Southern Observatory’s Very Large Telescope (VLT) to observe the Sun-like star TYC 8998-760-1, 300 light-years from Earth.
Using the VLT’s Spectro-Polarimetric High-contrast Exoplanet Research (SPHERE) instrument, which is equipped with an optical mask called a coronagraph to block out a star’s light, they were able to see two planets orbiting it (pictured above),.
