No, Jupiter is not dark. It is a gas giant planet that reflects a significant amount of sunlight due to its composition and atmosphere. Jupiter is actually one of the brightest objects in the night sky when viewed from Earth.
The bands on Jupiter are areas of alternating light and dark clouds that are caused by differences in the planet's atmospheric composition and temperature. The most prominent bands are the equatorial bands and the polar bands, which are visible in Jupiter's atmosphere.
Jupiter does not have a solid surface like Earth. Its atmosphere is primarily made up of hydrogen and helium, with smaller amounts of other gases like methane and ammonia. Below the swirling clouds of its atmosphere, Jupiter's interior is thought to be made up of a dense core of rock and metal surrounded by a layer of metallic hydrogen.
The Earth's atmosphere is primarily composed of nitrogen (78%) and oxygen (21%), with trace amounts of other gases like carbon dioxide and argon. Gas giants like Jupiter and Saturn have atmospheres predominantly made of hydrogen and helium, with traces of other gases like methane and ammonia. These differences in composition are due to the different formation processes and sizes of the planets.

Jupiter's atmosphere is comprised of about 90 percent hydrogen and 10 percent helium. Jupiter is a gas giant and has no real solid surface.
Jupiter's atmosphere is 90 percent hydrogen and 10 percent helium. There are also some small amounts of sulfur, ammonia, water vapor and methane.
Hydrogen and helium make up 99 percent of Jupiter's atmosphere. These two gases are the most abundant elements in the planet's composition.
Jupiter's atmosphere is composed primarily of hydrogen and helium with trace amounts of other gases like methane and ammonia. There is no sulfuric air on Jupiter as sulfur compounds are not prominent in its composition.
Jupiter's atmosphere is extremelythick.
Galileo was an unmanned spacecraft designed to study Jupiter and its moons. On 13 July 1995, the Galileo Orbiter and the probe separated for the latter to penetrate Jupiter's atmosphere. Its scientific objectives included measuring Jupiter's temperature, chemical composition and its atmospheric pressure structure. The probe entered Jupiter's atmosphere on 7 December 1995.
The composition of Jupiter's atmosphere is quite different from Earth's--Jupiter is composed mostly of hydrogen and helium, the same elements that make up most stars. In fact, we expect that Jupiter has basically the same composition as the Sun. Like the Sun, Jupiter has its own heat source, but Jupiter's heat comes from heat left over from the formation of the planet 4.5 billion years ago, and heat produced today due to the slight contraction of the planet under its own gravity. This means that Jupiter's composition might be very much like the original solar nebula from which it--and the solar system--formed, so investigating Jupiter's atmosphere is a way for us to investigate the early solar system.
No, Jupiter is not dark. It is a gas giant planet that reflects a significant amount of sunlight due to its composition and atmosphere. Jupiter is actually one of the brightest objects in the night sky when viewed from Earth.
The most abundant element in Jupiter's atmosphere is hydrogen, making up around 90% of its composition. Helium is the next most abundant, followed by smaller amounts of methane, ammonia, and water vapor.
