Do any other planets have oceans?

Currently, Earth is the only known planet (or moon) to have consistent, stable bodies of liquid water on its surface. Also in 2015, scientists used data from NASA’s Cassini mission to discover that a global ocean lies beneath the icy crust of Saturn’s moon Enceladus.

Can a gas giant have an ocean?

In a new study based on this mechanism, DTM astrophysicist John Chambers found that gas giants in early stages of formation may have had oceans with steaming atmospheres before growing into gas-rich, Jupiter-like giants. The study is available as an early online release by The Astrophysical Journal.

What planet has liquid oxygen?

The global ocean on Jupiter’s moon Europa contains about twice the liquid water of all the Earth’s oceans combined. New research suggests that there may be plenty of oxygen available in that ocean to support life, a hundred times more oxygen than previously estimated.

How is hydrogen sulfide produced in the ocean?

When the plants die, they sink to the ocean floor where bacteria begin to break them down. The oxygen is quickly used in the decay process, and anaerobic bacteria take over. These bacteria emit hydrogen sulfide gas as a by-product. The gas builds on the ocean floor until it erupts suddenly.

What planets have liquid water?

Liquid water in the Solar System

• Mars.
• Europa.
• Enceladus.
• Ganymede.
• Ceres.
• Ice giants.
• Pluto.
• Spectroscopy.

What planets have ice?

Uranus and Neptune both contain chemicals like methane, sulfur and ammonia in their atmospheres. It’s really cold that far away from the Sun. So, these chemicals might be frozen or trapped in crystals of ice. Because of this, Uranus and Neptune are called “ice giants.”

How does Jupiter have an ocean?

Structure. The composition of Jupiter is similar to that of the Sun – mostly hydrogen and helium. Deep in the atmosphere, pressure and temperature increase, compressing the hydrogen gas into a liquid. This gives Jupiter the largest ocean in the solar system – an ocean made of hydrogen instead of water.

Can air be created on Mars?

NASA’s Perseverance rover just created a breath of fresh air on Mars. An experimental device on the rover split carbon dioxide molecules into their component parts, creating about 10 minutes’ worth of breathable oxygen.

What is hydrogen sulfide in the ocean?

The anaerobic bacteria that complete the decay process release toxic hydrogen sulfide into the ocean. The gas builds near the ocean floor until a bubble erupts to the surface. As it rises, the hydrogen combines with oxygen to form water molecules, leaving solid, yellow sulfur.

What is the source of the toxic hydrogen sulfide gas that may have killed most of the plants and animals during the Permian extinction?

In the end-Permian, as the levels of atmospheric oxygen fell and the levels of hydrogen sulfide and carbon dioxide rose, the upper levels of the oceans could have become rich in hydrogen sulfide catastrophically. This would kill most of the oceanic plants and animals.

Which planet has liquid water on its surface?

Earth is the only known planet to have bodies of liquid water on its surface. Europa is thought to have subsurface liquid water. Scientists hypothesize that Europa’s hidden ocean is salty, tidal, and causes its ice surface to move, resulting in large fractures which are clearly visible in the above image.

Are there oceans on other planets?

What is the smallest planet with water vapor?

Water vapor has been discovered on a planet roughly the size of Neptune; the smallest exoplanet known to have water. HAT-P-11b is 120 light years away in the constellation Cygnus and sits close to its star in a five-day orbit. This world is likely too warm for oceans, but has water vapor and clear, cloudless skies.

What is an ocean world planet?

An ocean world, ocean planet, water world, aquaplanet, or panthalassic planet is a type of terrestrial planet that contains a substantial amount of water as hydrosphere on its surface or as a subsurface ocean.
