A chain of craters on Ganymede, probably caused by a similar impact event.The picture covers an area approximately 190 km (120 mi) across. Jupiter is a gas giant planet with no solid surface; the lowest atmospheric layer, the troposphere, gradually changes into the planet's inner layers. [10]
51 Eridani b was announced in August 2015, but was discovered in December 2014 using the Gemini Planet Imager, an international project led by the Kavli Institute for Particle Astrophysics and Cosmology. 51 Eridani b is the first exoplanet discovered by the Gemini Planet Imager. [5] The Gemini Planet Imager was specifically created to discern ...
Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.
Due to a safing event prior to the encounter, nearly all of the observations planned for the January 2002 flyby were lost. [2] In order to prevent potential biological contamination of the possible Europan biosphere, the Galileo mission ended on September 23, 2003 when the spacecraft was intentionally crashed into Jupiter.

The solar system's largest moon, Ganymede, which orbits the largest planet, Jupiter, was hit by an asteroid four billion years ago that shifted the gas giant's satellite on its axis, new research ...
Calculations showed that its unusual fragmented form was due to a previous closer approach to Jupiter in July 1992. At that time, the orbit of Shoemaker–Levy 9 passed within Jupiter's Roche limit, and Jupiter's tidal forces had acted to pull the comet apart. The comet was later observed as a series of fragments ranging up to 2 km (1.2 mi) in ...
Sometimes there can be more than one truth, even if merely a change in perspective. This could be part of the lesson with Mercury in Sagittarius opposing Jupiter retrograde in Gemini on Nov. 18 ...
Gemini. Farewell, comfort zone! Lucky, adventurous Jupiter sails through Gemini until June 9, making you crave novelty, variety, and adventure. This year’s theme is “expanded horizons,” and ...
