Coronal Mass Ejections At The Dawn Of The Solar System
Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs).

Hubble Reveals Complex Multi-scale Structure In The Edge-on Protoplanetary Disk IRAS 23077+6707
We present high-resolution (<0.1″) Hubble Space Telescope (HST)/Wide Field Camera 3 (WFC3) imaging of the near edge-on (i~80 deg) protoplanetary disk IRAS 23077+6707 (“Dracula’s Chivito”) obtained across six broadband filters […]

JWST-TST High Contrast: Medium-resolution Spectroscopy Reveals a Carbon-rich Circumplanetary Disk Around The Young Accreting Exoplanet Delorme 1 AB b
Young accreting planetary-mass objects are thought to draw material from a circumplanetary disk (CPD) composed of gas and dust.

A Scatter of Light from a Polarized World
Many known exoplanets harbor clouds, which lead to degeneracies in spectroscopic models between particle composition and size. Polarimetry, however, provides independent assessment.

Detection Of CO2, CO, and H2O In The Atmosphere Of The Warm Sub-Saturn HAT-P-12b
The chemical composition of warm gas giant exoplanet atmospheres (with Teq < 1000 K) is not well known due to the lack of observational constraints. HAT-P-12 b is a warm, […]
