More about Jupiter and Venus

Jupiter and the recent Juno and earlier Voyager Missions

Jupiter is the largest planet in the solar system.  One of its notable features is the Great Red Spot.  Another is its four large moons and other smaller moons, almost as if it is its own solar system.  Read more here from NASA about Jupiter and its four large moons, Io, Gannymead, Europa and Callisto, also known as the Galilean satellites.

Here is a picture, not to scale, of Jupiter and its four largest moons.  Below it is a picture of the Great Red Spot using false colors. Both the Great Red Spot and the montage of Jupiter and its four largest moons were assembled from photographs taken by Voyager I in 1979, collected at NASA’s Photo Gallery.

NASA’s Juno mission began in August, 2011 and is scheduled to conclude in 2016.  Juno’s mission is to learn more about the early history of our solar system.

Venus

Venus is shrouded in clouds, but not the water-vapor clouds of the Earth. Venus has clouds that are made of sulfuric acid. These clouds permanently shroud Venus’ volcanic surface.

Here is an ultraviolet photograph of Venus taken in 1995 by the Hubble Space Telescope.  Below it are five surface views of Venus taken during the Magellan mission (1989-1994).  Both photos can be found at NASA’s Photo Gallery. For more information on the five globes, see the caption provided by NASA Photo Gallery.

When viewing Jupiter and Venus in the evening sky, Jupiter is the brightest of the two – a magnificent duo!  See 3/9/12 post for the Solar System Scope and information on how to use it to find Jupiter, Venus and the nearby Constellation Orion in your night sky.
