Almost every night and almost every time. IR Pass filter is needed in all but the best seeing conditions however. Also don't forget we're imaging here and you have to image the Airy Disk as well. 5000 frames, stacked, sharpened in R6 with a Gamma boost to bring out the rings. If y...
The closest images yet of Jupiter's volcanic moon have revealed one of the major surface features is nearly as smooth as a sheet of glass! In December 2023 and February 2024, NASA's Juno spacecraft made close passes by Io, the innermost of Jupi...
Major Satellites: Jupiter has more than 70 known moons, including the four Galilean moons: Io, Europa, Ganymede and Callisto. These moons are remarkable for their size and geological diversity, and they harbor some of the most interesting environments in the solar system. Strong Magnetic Field: ...
Their albedos are quite high but lower than Jupiter’s albedo, implying the presence of surface features rather than the presence of a thick atmosphere. Indeed, radar and infrared observations have established that their surfaces consist of ice or an ice-rock mixture, since sizable irregularities ...
Jupiter has more moons than any other planet in our Solar System. But the exact Jupiter moons number is tough to calculate. Some astronomers estimate that Jupiter has over 200 sizeable objects orbiting the gas giant. Of those objects, 4 of them are classified as major moons. In comparison, ...
to be covered by 10 meter-tall icy spikes called penitentes, which are caused by the effect of direct overhead sunlight on the equator melting vertical cracks. The prominent markings crisscrossing Europa (calledlineae) are another major feature, which is thought to be mainly albedo features. ...
there. Then the main spacecraft spent eight years studying the system. When Galileo itself ran low on fuel, the spacecraft intentionally crashed into Jupiter to avoid any risk of it bringing contamination from Earth to Europa, which might have an ocean below its surface capable of supporting ...
Voyager, for the first time, revealed the complexity and diversity of Jupiter's major satellites and provided tantalizing clues to their surface histories. The features seen on the satellites prompted a re-examination of traditional geologic processes. The new data caused planetologists to consider ...
The moon's unique surface features are much easier to spot in more traditional photos. This one, captured on June 7, gives us Juno's view of Ganymede during the closest flyby of the moon by any spacecraft in the past 20 years. You can clearly see the intricate grooved terrain here, ...
Just how deep these features go, however, is entirely uncertain. [Photos: Jupiter, Largest Planet in the Solar System] "We don't know if the beautiful zones and belts are just a surface feature, and on the inside Jupiter's rotating like a solid body," said Scott Bolton, principal ...
