articleThe Brief A University of Arizona-led team discovered a growing planet, WISPIT 2b, forming inside a disk gap around a young star. The outer planet, WISPIT 2b, is estimated to be about five times the mass of Jupiter and is orbiting at a distance similar to the outer edge of the Kuiper Belt in our solar system. "To see planets in the fleeting time of their youth, astronomers have to find young disk systems, which are rare," van Capelleveen said. "If the WISPIT-2 system was the age of our solar system and we used the same technology to look at it, we’d see nothing." Researchers say WISPIT 2b will continue to be monitored in both visible and infrared light as new technology helps astronomers refine their understanding of planet formation.
