Does atmosphere exist on other planets and stars?

Answer 1

Yes, although other planets almost never have the same atmosphere that we have here on Earth.

For instance, here's Venus' atmosphere:

The pressure of Venus' atmosphere at the surface is 90 atmospheres (about the same as the pressure at a depth of 1 km in Earth's oceans). It is composed mostly of carbon dioxide. There are several layers of clouds many kilometers thick composed of sulfuric acid. These clouds completely obscure our view of the surface. This dense atmosphere produces a run-away greenhouse effect that raises Venus' surface temperature by about 400 degrees to over 740 K (hot enough to melt lead). Venus' surface is actually hotter than Mercury's despite being nearly twice as far from the Sun.

Answer 2

Not like our atmosphere, at least not that we've discovered so far, but yes, other planets and even moons have atmosphere. Saturn's moon Titan actually has an atmosphere that behaves quite similar to ours with clouds, rain, lakes, etc. The difference is that on Titan, it is made up of ethane and methane, rather than nitrogen and oxygen like we have here. That's an overly-simple answer, but those are the basics.

Answer 3

yes

Astronomers announced today the first detection of an atmosphere around a planet orbiting another star, a critical first step in understanding the skies above planets outside our solar system.
The discovery of a small amount of sodium above a large planet 150 light-years away shows that planets outside our solar system do in fact use their gravity to trap gases and possibly other substances to form an atmosphere. Until now, scientists could only assume that such objects have atmospheres, as do the planets in our solar system.

Answer 4

yeah! Atmosphere do exist on other planets. Don't get confused the atmosphere with the oxygen. Venus has the atmosphere of clouds of gasses of white color, thats why it luks so bright.
SImilarly other planets do have atmosphere

Answer 5

The atmosphere of Venus is composed mainly of carbon dioxide with minor amounts of nitrogen and trace amounts of nitrogen, helium, neon, and argon.

The Earth's atmosphere primarily composed of nitrogen and oxygen. Minor gases include and carbon dioxide, ozone, argon, and helium.

Mars' atmosphere is a thin layer composed mainly of carbon dioxide. Nitrogen, argon, and small traces of oxygen and water vapor are also present.

Jupiter's atmosphere contains mainly helium and hydrogen with trace amounts of water, ammonia, methane, and other carbon compounds. Three layers of clouds may exist in Jupiter’s outermost atmosphere. The lowest are made of water ice or droplets, the next are crystals of a compound of ammonia and hydrogen sulfide, and the highest clouds are ammonia ice. There seems to be no solid surface under the atmosphere, only a transition from gas to liquid metallic hydrogen. In the top one-fourth of the planet, the pressure and temperature are so high that the hydrogen atoms are stripped of their outer electrons, forming a liquid metal.

Like Jupiter, Saturn has a thick atmosphere composed of hydrogen and helium. The ratio of hydrogen to helium ratio decreases with depth. Methane and ammonia are also present. The atmosphere of Saturn envelops a thick layer of metallic hydrogen.

Uranus' atmosphere is composed mainly of hydrogen and minor amounts of helium Methane is present in minor amounts, and probably forms most of the clouds seen by space probes and telescopes. Uranus and Neptune both appear blue because methane strongly absorbs light of other wavelengths.

The atmosphere of Neptune consists mainly of hydrogen and helium, but about 2.5-3% of the atmosphere is methane. Like Uranus, clouds in Neptune's atmosphere are composed of crystals of methane.

Pluto's atmosphere seems to be very thin, and is likely composed of nitrogen and carbon dioxide.
star:-
A nova that lights up in the sky every 20 years is the result of a small star exploding repeatedly inside the outer atmosphere of a larger star, astronomers said today.

Hydrogen gas from the outer atmosphere of the red giant is lured by gravity to the smaller white dwarf. Every 20 years, enough gas builds up to create a runaway thermonuclear explosion on the white dwarf's surface. In less than a day, the otherwise dim star brightens to more than 100,000 times the luminosity of the Sun. Much of the gas is shot into space.

"This explosion is similar to that of a terrestrial hydrogen bomb,"

Answer 6

yes but not like ours.its usually composed of other elements depending on the planet/star.

Answer 7

Yes, but made up differently than our. Check out a book at the library and check it out.

Answer 8

yea atmosphere is there

Answer 9

I believe it can, but it would not be the exact same as our world.

Answer 10

Yes... oxygen not always.
