Giant, gas-rich planets may have been able to form more easily in the very early universe than they do today, according to astounding new findings from the James Webb Space Telescope (JWST) that corroborate earlier Hubble Space Telescope evidence.
In 2003, Hubble found a massive exoplanet. There's nothing too unusual about that, but closer inspection revealed the planet, called PSR B1620-26b, to be quite weird. It orbits not one but two objects, a pulsar and a white dwarf. These are the cinders of two dead stars — a massive star that went supernova and a sun-like star, respectively — and was the first circumbinary exoplanet to be discovered (circumbinary meaning orbiting two stars, like Tatooine in "Star Wars").
