The European Southern Observatory’s (ESO) Very Large Telescope (VLT) has discovered what is believed to be a baby planet being formed through images of flaming orange swirls.
The observation was reported in a study published this Wednesday in the journal Astronomy & Astrophysics. The baby star system, dubbed as AB Aurigae, was found around 520 lightyears away from Earth in the Auriga constellation, and might be the first evidence of a new planet being born.
The orange swirls are formed by an intense disc of dust and gas, and the yellow twist in the middle is a telltale sign of a baby planet growing in the universe. “The twist is expected from some theoretical models of planet formation,” explained Anne Dutrey, co-author of the report and a researcher at the Astrophysics Laboratory of Bordeaux in France.
