What could it be?
NASA’s groundbreaking James Webb Space Telescope has spotted a mysterious object that’s freely floating through interstellar space.
According to NASA, the “planetary-mass” object, dubbed SIMP 0136, is roughly 13 times the mass of Jupiter, and is located just 20 light-years from Earth. It’s also spinning at a breakneck speed, completing a full rotation every 2.4 hours.
Thanks to the JWST’s detailed infrared light observations, an international team of researchers detected signs of “complex atmospheric features,” including possible cloud layers and temperature shifts in the object’s atmosphere, as detailed in a study they published in the journal The Astrophysical Journal Letters.
It’s a fascinating glimpse at an exceedingly rare object. The researchers suggest in their paper that objects like SIMP 0136 could much in common with cloud giants in the solar system, like Jupiter and Saturn, which “also have multiple cloud layers and high-altitude hot spots” (except that it’s floating through space without a star, that is.) Astronomers also aren’t ruling out the possibility that it’s a brown dwarf, an object that’s between a planet and a star.
The latest research builds on existing observations by NASA’s Hubble and Spitzer space telescopes.
