Observations of Uranus at High Phase Angle as Seen by New Horizons

Samantha N. Hasler, L. C. Mayorga, William M. Grundy +14

We present flux measurements of Uranus observed at phase angles of 43.9°, 44.0°, and 52.4° by the Multispectral Visible Imaging Camera (MVIC) on the New Horizons spacecraft during…

Prominent mid-infrared excess of the dwarf planet (136472) Makemake discovered by JWST/MIRI indicates ongoing activity

Csaba Kiss, Thomas G. Müller, Anikó Farkas-Takács +18

We report on the discovery of a very prominent mid-infrared (18-25 μm) excess associated with the trans-Neptunian dwarf planet (136472) Makemake. The excess, detected by the MIRI i…

A Contact Binary Satellite of the Asteroid (152830) Dinkinesh

Harold F. Levison, Simone Marchi, Keith S. Noll +3

Asteroids with diameters less than about 5 km have complex histories because they are small enough for radiative torques, YORP, to be a notable factor in their evolution. (152830)…

Revealing Callisto's carbon-rich surface and CO2 atmosphere with JWST

Richard J. Cartwright, Geronimo L. Villanueva, Bryan J. Holler +18

We analyzed spectral cubes of Callisto's leading and trailing hemispheres, collected with the NIRSpec Integrated Field Unit (G395H) on the James Webb Space Telescope. These spatial…

Measurement of D/H and 13C/12C Ratios in Methane Ice on Eris and Makemake: Evidence for Internal Activity

W. M. Grundy, I. Wong, C. R. Glein +11

James Webb Space Telescope's NIRSpec infrared imaging spectrometer observed the outer solar system dwarf planets Eris and Makemake in reflected sunlight at wavelengths spanning 1 t…

JWST molecular mapping and characterization of Enceladus' water plume feeding its torus

G. L. Villanueva, H. B. Hammel, S. N. Milam +18

Enceladus is a prime target in the search for life in our solar system, having an active plume likely connected to a large liquid water subsurface ocean. Using the sensitive NIRSpe…
