The High Plasma Density Observed Along the PJ57 Juno Flyby of Io Implies the Presence of a Dense Atomic Corona

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract On December 2023, the Juno spacecraft made a flyby of Io above the northern hemisphere at a closest approach (CA) altitude of ∼1,500 km (PJ57). The Juno/Waves and Radio‐occultation measurements showed a surprising large electron density ∼28,000 cm−3 near closest approach.

Evidence for a Nonzero Eccentricity Superpuff Exoplanet WASP-107 b Using JWST Occultation Observation

The Astrophysical Journal Letters
WASP-107 b is an extremely low-density superpuff exoplanet whose inflated radius and evidence of strong internal heating make it a key target for understanding planetary structure and evolution.

Observing Exoplanets with the James Webb Space Telescope [PDF]

, 2011
The search for exoplanets and characterization of their properties has seen increasing success over the last few years. In excess of 500 exoplanets are known and Kepler has approx. 1000 additional candidates.

Overview of the James Webb Space Telescope Observatory [PDF]

, 2011
The James Webb Space Telescope (JWST) is a cryogenic, 6.5 meter diameter space telescope. JWST has a unique architecture, compared to previous space telescopes, that is driven by its science requirements, ia passively cooled cryogenic design, and the ...

Observing Exoplanets with the James Webb Space Telescope [PDF]

The census of exoplanets has revealed an enormous variety of planets or- biting stars of all ages and spectral types: planets in orbits of less than a day to frigid worlds in orbits over 100 AU; planets with masses 10 times that of Jupiter to planets ...

Fate of James Webb Space Telescope murky [PDF]

Eos, Transactions American Geophysical Union, 2011
The James Webb Space Telescope (JWST), the next‐generation successor to the Hubble Space Telescope, was put on the chopping block by the U.S. House of Representatives Appropriations Subcommittee on Commerce, Justice, Science, and Related Agencies. The subcommittee approved a measure on 7 July that “terminates funding for [JWST], which is billions of ...

The James Webb Space Telescope NIRSpec-PRISM Transmission Spectrum of the Super-puff, Kepler-51d

The Astronomical Journal
Kepler-51 is a 500 Myr G dwarf hosting three “super-puffs” and one low-mass nontransiting planet. Kepler-51d, the coolest ( T _eq ∼ 350 K) transiting planet in this system is also one of the lowest-density super-puffs known to date ( ρ _p = 0.038 ± 0.009
