Relaying this from the ALMA Observatory account "over there”…

A Surprise Chemical Find by ALMA May Help Detect and Confirm Protoplanets. Located in the constellation Sagittarius, the young star HD 169142 is host to a giant protoplanet embedded within its dusty, gas-rich protoplanetary disk.

You had me at "Space Hurricane." :)

When new planets form in distant solar systems, they carve out space hurricanes and vortices in the surrounding dust that could lead astronomers straight to them.

... notes on planetary disk formation

The early environment around a new star, the protoplanetary disk, contains dust and gas left from the collapse of the interstellar cloud that led to the star formation. The star and the disk of debris rotate on a common center of gravity, and this disk of debris could lead to the formation of planets.

After launch, the #LucyMission to the Trojan #asteroids saw that 1/2 solar arrays wasn't deploying. The team worked out a plan to use the primary and backup deployment motors together, pulling to the motors' limits, resting, then going again. After jerking on it a bunch, Lucy can now continue on her mission.
