* Astronomers from the Astronomical Observatory of Palermo, National Institute for Astrophysics (INAF), and the University of St Andrews investigated the 5–10 Jupiter mass free-floating planetary-mass object (FFPMO) Cha 1107-7626 during a powerful and protracted accretion outburst event.
* The X-shooter spectrograph on the European Southern Observatory’s (ESO’s) Very Large Telescope (VLT) detected an enhanced mass accretion rate of 10−7MJupiter​yr−1, corresponding to six billion tonnes per second, between June and August 2025.
* According to lead author Víctor Almendros-Abad, this finding provides the strongest evidence yet for a planetary-mass object behaving like an EXor-type variable star, profoundly challenging current planetary formation models.

The newly studied object, which has a mass five to 10 times the mass of Jupiter…   …this rogue planet is still forming and is fed by a surrounding disc of gas and dust. This material constantly falls onto the free-floating planet, a process known as accretion…   …at a rate of six billion tonnes a second.
