First Ever Live Observation Of The Rotation Of A Planetary Nursery

by Keith CowingJune 4, 2026June 4, 2026

The rotation of a protoplanetary disc (a disc where planets are being formed) has been observed directly for the very first time by mapping the emissions from the dust grains […]

VLT/MUSE Detection Of The AB Aurigae b Protoplanet With Ha Spectroscopy

by Keith CowingAugust 29, 2025

We analyze high-contrast, medium-spectral-resolution Hα observations of the star AB Aurigae using the Very Large Telescope’s Multi Unit Spectroscopic Explorer (MUSE).
