Astronomers discover a bizarre ‘runaway’ planet acting like a star.

The article discusses the discovery of a rogue planet named Cha 1107-7626, which is reportedly the fastest-growing free-floating planet, consuming gas and dust at an unprecedented rate of 6 billion tonnes per second. Observations from the European Southern Observatory’s Very Large Telescope and the James Webb Space Telescope revealed that the planet experiences significant fluctuations in its accretion rate, with bursts occurring that may indicate similarities between rogue planets and young stars. Researchers aim to understand whether such rogue planets are remnants of ejected planetary systems or formed independently from molecular cloud material. The findings could provide insights into the formation processes of both stars and planets, as well as the broader mechanisms behind accretion bursts. [Extracted from the article]
