This handout picture released by the the European Southern Observatory on January 13, 2016 shows the bright, young stars known as the Trapezium Cluster, located in the heart of the Orion star-forming region, observed with the new GRAVITY instrument. From these first data, GRAVITY made a discovery: one of the components of the cluster (Theta1 Orionis F, lower left) was found to be a double star for the first time. The brighter double star Theta1 Orionis C (lower right) is also well seen. The background image comes from the ISAAC instrument on ESO's Very Large Telescope. The views of two of the stars from GRAVITY, shown as inserts, reveal far finer detail than could be detected with the NASA/ESA Hubble Space Telescope.
