Galileo [9] [10] discovered the Galilean moons. These satellites were the first celestial objects that were confirmed to orbit an object other than the Sun or Earth. Galileo saw Io and Europa as a single point of light on 7 January 1610; they were seen as separate bodies the following night. [11] Callisto: Jupiter IV o: 8 January 1610 p: 13 ...

The original tapes were carefully archived for 20 years by the government in Maryland. When the tapes were released back to NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, in 1986, the decision of whether to scrap the tapes became the responsibility of JPL archivist Nancy Evans. She decided that the tapes should be preserved.
The new discovery increases the moons orbiting the "jewel of our solar system" to 82, surpassing Jupiter 20 new moons were discovered around Saturn Skip to main content
The danger was highlighted in 1969 when the Apollo 12 astronauts returned components of the Surveyor 3 spacecraft that had landed on the Moon three years before, and it was found that microbes were still viable even after three years in that harsh climate.
Eventually, new moons were discovered also around Uranus starting in 1787 by Herschel, [23] around Neptune starting in 1846 by William Lassell [24] and around Mars in 1877 by Asaph Hall. [25] Further apparent discrepancies in the orbits of the outer planets led Percival Lowell to conclude that yet another planet, "Planet X", must lie beyond ...
Researchers at University of California Berkeley have obtained an exceptionally detailed map of the largest known lava lake in our solar system.. Located on Jupiter's moon Io, the lava lake known ...
There are 293 confirmed moons in our cosmic neighborhood. By studying these worlds, astronomers hope to learn about ancient asteroid collisions, space volcanoes, and the origins of life itself.
