| Astronomers have observed a planet that in some ways behaves more like a star including a massive growth spurt unlike anything witnessed before in a free-floating planet.

The rogue planet, which does not orbit any star, is called Cha 1107-7626 and is outside of our solar system, 620 light-years from Earth in the Chamaeleon constellation. A single light-year, or the distance light travels in one year, is equal to 5.88 trillion miles (9.46 trillion kilometers).
The planet has a mass five to 10 times that of Jupiter, the largest planet in our solar system. And its getting bigger every second, according to new research published Thursday in The Astrophysical Journal Letters.
Estimated to be 1 million to 2 million years old, Cha 1107-7626 is still forming, said study coauthor Aleks Scholz, an astronomer at the University of St. Andrews in Scotland. It may sound old, but astronomically speaking, the planet is in its infancy. By contrast, the planets in our solar system are about 4.5 billion years old.

Cha 1107-7626 is surrounded by a disk of gas and dust, which constantly falls onto the planet and accumulates during a process that astronomers call accretion |

| Astronomers first discovered Cha 1107-7626 in 2008, and since then, they have observed it with different telescopes to learn more about how the infant planet evolves, as well as to study its surroundings.

The research team observed the planet with Webb in 2024, making a clear detection of the surrounding disk. Next, the researchers studied it using the X-shooter spectrograph on the Very Large Telescope, which can capture different wavelengths of light emitted by an object ranging from ultraviolet to near-infrared.
The observations detected a puzzling event as the planet transitioned from a steady accretion rate in April and May to a burst of growth between June and August.

I fully expected that this is a short-term event, because those are much more common, Scholz said. When the burst kept going through July and August, I was absolutely stunned.
Follow-up observations made using the Webb telescope also showed that the chemistry of the disk had changed. Water vapor, present during the growth spurt, wasnt in the disk before. Webb is the only telescope capable of capturing such detailed changes in the |

| Its like you read my mind! You seem to know so much about this, like you wrote the book in it or something. I think that you can do with some pics to drive the message home a bit, but instead of that, this is fantastic blog. A fantastic read. I'll definitely be back.
