Steady Collapse of Uranus' Exosphere After 1998 to the Present Decade
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Uranus' thermospheric temperature decreased from ∼800K in 1986 to ∼450K in 2022 as determined from observations of H3+ and H2 infrared emissions. Spitzer 2007 lower atmosphere observations do not emulate this cooling trend. Here we show that the atomic H Lyman ⍺ emission from the disk of Uranus observed by HST from 2011 to 2022 are not ...

Saturn orbiter mission study [PDF]
A preliminary analysis of the important aspects of missions orbiting the planet Saturn is provided. Orbital missions to Saturn is given serious consideration for the 1980's, or after flybys by Pioneer 10/G and Mariner Jupiter-Saturn 1977.

Modeling the EMIC Wave‐Induced Acceleration of Energetic Protons in the Io Footprint Tail
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract The Io footprint tail (FPT) region is crucial for studying the interactions between Io and Jupiter's magnetosphere. In this region, Juno spacecraft observed significant acceleration of energetic protons, concurrently with electromagnetic ion cyclotron (EMIC) waves below the proton gyro‐frequency.

Has Kronos Devoured Planet Nine and Its Epigones?
UniverseThe Planet Nine hypothesis encompasses a body of about 5–8 Earth’s masses whose orbital plane would be inclined to the ecliptic by one or two tens of degrees and whose perihelion distance would be as large as about 240–385 astronomical units. Recently, a
