Cambridge, U.K.—A set of four modest telescopes at the University of Cambridge has achieved an astronomical first by merging their light into single images. The technique, known as imaging interferometry, should yield views as sharp as those from a single telescope with a mirror tens or even hundreds of meters across. The first images bear out that promise, showing the binary star Capella at five times the resolution available from the Hubble Space Telescope.
