These ‘pebbles’ detected for 1st time: crucial link in building planets. Since1990s, astronomers have found both disks of gas and dust, and nearly 2000 fully formed planets, but the intermediate stages of formation are harder to detect.
Dr Greaves and Dr Anita Richards from Manchester University used e-MERLIN array of radio telescopes centred on Jodrell Bank, Cheshire, and that stretches across England in an interferometer, mimicking resolution of a single large telescope. They observed the star DG Tauri, a youthful star just 2.5 million years old and 450 light years away in constellation of Taurus. Looking at radio wavelengths, they discovered a faint glow characteristic of rocks in orbit around the newly formed star.
