During Thursday's flyby, NASA's Juno probe made important observations about Europa, a leading candidate in the search for life beyond Earth. Side-by-side images from flybys of Europa show close ...
The region of lineae at the center of this image is the Annwn Regio. [62] [63] Europa's most striking surface features are a series of dark streaks crisscrossing the entire globe, called lineae (English: lines). Close examination shows that the edges of Europa's crust on either side of the cracks have moved relative to each other.
JunoCam successfully returned detailed images of Ganymede after Juno's flyby on June 7, 2021, [6] with further opportunities including planned flybys of Europa on September 29, 2022, and two of Io scheduled for December 30, 2023 and February 3, 2024. These flybys will also reduce Juno's orbital period to 33 days. [7]
In 2016, the Juno spacecraft imaged the Galilean moons from above their orbital plane as it approached Jupiter orbit insertion, creating a time-lapse movie of their motion. [75] With a mission extension, Juno has since begun close flybys of the Galileans, flying by Ganymede in 2021 followed by Europa and Io in 2022. It flew by Io again in late ...
Europa (Jupiter II), the second of the four Galilean moons, is the second closest to Jupiter and the smallest at 3121.6 kilometers in diameter, which is slightly smaller than Earth's Moon. The name comes from a mythical Phoenician noblewoman, Europa , who was courted by Zeus and became the queen of Crete , though the name did not become widely ...
Juno ' s UVS instrument Ultraviolet image of Jupiter's aurora; the bright spot at far left is the end of field line to Io; spots at bottom lead to Ganymede and Europa.This was taken by the Hubble Space Telescope from Earth orbit, using the Space Telescope Imaging Spectrograph Here is an observation of Jupiter in X-rays by Chandra.
Nonetheless, Pioneer 10 did succeed in obtaining images of the moons Ganymede and Europa. The image of Ganymede showed low albedo features in the center and near the south pole, while the north pole appeared brighter. Europa was too far away to obtain a detailed image, although some albedo features were apparent. [47]
