Summary

Story summary

Astronomers have identified a new gas giant, WISPIT 2b, in a protoplanetary disk around the young star WISPIT 2, 400 light-years away.
WISPIT 2b has a mass approximately five times that of Jupiter and is still gathering material from the disk.
This discovery enhances understanding of planet formation and protoplanetary disk dynamics.
The research is published in the Astrophysical Journal Letters.
