6 rogue planets spotted by NASA Webb telescope, 'they are bigger than...'

Astronomers using the James Webb Space Telescope have detected six rogue worlds-cosmic objects that do not orbit stars.

These celestial bodies are slightly larger than Jupiter and provide new insights into star and planet formation across the universe.

The Webb telescope observed the star-forming nebula NGC 1333, located 960 light-years away within the Perseus molecular cloud.

Within the nebula, Webb identified newborn stars, brown dwarfs, and objects with planetary masses, all about five to ten times more massive than Jupiter.

Planetary-mass objects can form in two distinct ways: contraction of gas and dust clouds, similar to stars, or from disks of gas and dust around young stars, as in the case of Jupiter.

The Webb telescope also discovered a rare pair: a brown dwarf with a companion object of planetary mass, likely formed from a fragmenting cloud.

As researchers continue to study these rogue worlds, the upcoming NASA's Nancy Grace Roman Space Telescope, set to launch in May 2027, may further illuminate nature of these wandering planets.
