Double Star Detected By New Black Hole Probe | Video

Known simply as 'Gravity', this multi-mode interferometer combines light from several telescopes to enable observations simulating a single extremely large telescope. Applied to the European Southern Observatory's Very Large Telescope array, ‘Gravity’ detected a binary star pair within the Trapezium Cluster during its first observing run.
