World's most powerful space telescope- James Webb Space Telescope (JWST)- has spotted Jupiter-sized planets that are free-floating in space, unconnected to any star. The planets, nicknamed 'Jupiter Mass Binary Objects' or "JuMBOs", have been found moving in pairs. Around 40 pairs of JuMBOs have been found in the Orion Nebula, experts said, adding that they're exploring theories of their origin.
