The astronomers found 40 pairs of JuMBOs and two triple systems, all on wide orbits around one another. “Although some of them are more massive than the planet Jupiter, they will be roughly the same size and only slightly larger,” said Pearson, a European Space Agency research fellow at the European Space Research and Technology Centre in the Netherlands. The scientists dubbed them Jupiter Mass Binary Objects, or JuMBOs. On the hunt for other low-mass isolated objects, the astronomers found something they had never seen: pairs of planet-like objects with masses between 0.6 and 13 times the mass of Jupiter that appear to defy some fundamental astronomical theories. Brown dwarfs have a mass that is below 7% the mass of the sun. In addition to the stars, the scientists spotted brown dwarfs, which are too small to kick-start the nuclear fusion at their cores to become stars. McCaughrean studied the short-wavelength image of the Orion Nebula, they zoomed in on the Trapezium Cluster, a young star-forming region that’s about 1 million years old, filled to the brim with thousands of new stars. Located 1,300 light-years from Earth, the nebula has long presented astronomers with a wealth of celestial objects to study, including planet-forming disks around young stars and brown dwarfs, or objects with a mass between that of planets and stars.Īstronomers used Webb’s near-infrared camera, called NIRCam, to capture mosaics of the Orion Nebula in short and long wavelengths of light, revealing unprecedented details and unexpected discoveries. The Orion Nebula, a glowing cloud of dust and gas, is one of the brightest nebulae in the night sky and identifiable as the sword in the Orion constellation. New images from the James Webb Space Telescope have revealed surprising pairs of planet-like objects in the Orion Nebula that have never been detected before.
