Cool Worlds Lab released another great video recently that discusses rogue planets, or planets without a host star, in a video titled “A JuMBO Mystery – This Shouldn’t Happen!”
A JuMBO means Jupiter-mass binary objects, which is just part of the story in this video. The presentation starts with a finding from astronomers using the James Webb Space Telescope, who identify 520 rogue planet candidates. This is interesting in itself, but the intriguing part is that a number of these planets are found in pairs. This would not make a lot of sense if we believed these planets were once within a solar system before being pushing into space.
The video discusses the various theories explaining these JuMBOs and rogue planets in general. It also discusses the potential impact on our own solar system, such as whether we lost one of our own planets in the past and/or a nearby rogue planet (and its moons) is out there today waiting to be discovered.
As always, Cool Worlds Lab keeps astronomy even more interesting.
