Rogue planets are planetary bodies that don’t orbit a host star, instead hurtling through space seemingly randomly. Now the James Webb space telescope has identified several of them and they’re wandering through an utterly gorgeous part of space.
00:00Rogue planets are planetary bodies that don't orbit a host star, instead hurtling through space seemingly randomly.
00:10Experts believe many of them form in binary star systems and were ultimately ejected from them left to wander the cosmos.
00:16Now the James Webb Space Telescope has identified several of them and they're wandering through an utterly gorgeous part of space.
00:23This is a star forming nebula in the Perseus constellation.
00:27Astronomers say they have found 6 rogue planets meandering through it.
00:30Rogue planets are of interest to astronomers as we don't currently know the limit at which a body of coalescing material may collapse and become a star, as opposed to remaining a massive planet.
00:39Meaning experts wonder if rather than being jettisoned from a star system, some rogue planets were meant to be stars, but simply never got there.
00:46And the most recent rogue planets discovered are huge, between 5 and 10 times the mass of Jupiter, our solar system's most massive planet.
00:54With the researchers concluding after this new discovery, our observations confirm that nature produces planetary mass objects in at least two different ways.
01:01From the contraction of a cloud of gas and dust, the way stars form, and in discs of gas and dust around young stars, as Jupiter in our own solar system did.
