Astronomy’s first gap-clearing planet fills in our “missing link”
We've seen protoplanetary disks with gaps, and fully mature systems with directly imaged planets.
For the first time, we've found them together: a disk-gap with an exoplanet inside.

Astronomy's first gap-clearing planet fills in our "missing link"
Planets grow from protostellar material in disks, leading to full-grown planetary systems in time. At last, the final gap has been filled.

Despite continuing to build fossil fuel capacity, new renewable capacity added is allowing China to meet all or nearly all of their demand growth. Because renewables are cheaper to operate, they queue earlier than fossil fuel capacity. The outcome will thus be further reduction in emissions. 🧪🔌💡☀️💨💧🔋
