GO 11630 Monitoring active Atmospheres on Uranus and Neptune
![]() |
The atmospheres of the gas giant planets in the solar system are dynamic entities that can exhibit dramatic changes over a variety of timescales. Those changes are most apparent in Jovian atmosphere, which displays a wide variety of bands and spots, reflecting complex meteorological phenomena (see, e.g., previous ACS observations of the upper atmosphere and of the new little red spot ). This is not surprising since Jupiter atmosphere receives the highest input of solar energy. However, secular variations are also evident in the atmospheres of the outer planets, albeit usually at a more subtle level. The present program builds on past HST programs (see Program GO 10534 ) that have monitored atmospheric changes in the two outermost gas giants, Uranus and Neptune. Both exhibit long-term seasonal variations, whose origins are not yet well understood; both are capable of generating dark spots - phenomena that are presumably related to Jupiter's Great Red Spot and Saturn's Great White Spot. The present observations use a variety of filters on Wide-Field Camera 3 (notably the quad methane filter) to probe conditions are a variety of levels within the planetary atmospheres. |
