SIMP 0136 is the brightest free-floating planetary-mass object in the northern sky.

It has a mass about 13 times that of Jupiter , and is thought to have the structure and chemical composition of a giant gas planet.

Researchers from Boston University and other institutions recently conducted detailed observations of the planet using the James Webb Space Telescope .

They used the telescope’s Near Infrared Spectrograph (NIRSpec) and its Mid Infrared Observatory (MIRI) to observe the object for over three hours , enough to cover the entire planet's rotation.

However, it is difficult to explain all the changes in infrared brightness just by cloud and temperature variations. For this reason, the research team points out that there may be areas in SIMP 0136’s atmosphere where carbon monoxide and carbon dioxide are concentrated, and that these areas may also affect the infrared brightness as the planet rotates.
