Scientists studying a rogue planet called Cha 1107-7626, located 620 light-years from Earth in the constellation Chamaeleon, have witnessed an extraordinary growth spurt. Unlike planets in our solar system, this free-floating planet does not orbit a star but is growing rapidly, consuming six billion tonnes of gas and dust every second.
The planet, estimated to be five to ten times the mass of Jupiter, has recently accelerated its growth rate to eight times what was observed just months ago — the fastest planetary growth ever recorded. Its feeding frenzy resembles the behavior of young stars, blurring lines between planet and star formation.
Researchers speculate that a strong magnetic field unique for its size plays a critical role in this growth. Observations show that the chemistry of the planet’s atmosphere changes during these bursts, further linking its evolution to star-like processes.
