Is there water on any other planet than Earth?

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.

How did water come to Earth?

If Earth was born a hot and dry planet, the water must have arrived later, after the planet had cooled, presumably brought by icy comets and asteroids from far out in the solar system, which bombarded the young planet, seeding it with their water, some of which stayed on the surface and became our oceans, while the …

How do we get water from Mars?

Baked rocks There is also another option for collecting water: We could extract it from hydrated minerals, which are plentiful in many areas of Mars. There are rocks like gypsum there that contain water, and if you crush, then bake those rocks, you can condense the water and collect it.

Is it possible for life to exist without water?

Water is the liquid that makes life on Earth possible. Without water, life as we know it would not exist. And life exists wherever there is water. All organisms, like animals and plants, use water: salty or fresh, hot or cold, plenty of water or almost no water at all.

What would happen to Earth if it was moved to Venus?

At first glance, this seems very probable. If the Earth was pushed inwards to Venus’s orbit, then water would start to rapidly evaporate. Like carbon dioxide, water vapour is a greenhouse gas and helps trap heat. The planet’s temperature would therefore keep increasing in a runaway cycle until all water had evaporated.

What would happen if there was water on Mars?

This would lead to extreme seasons and temperature gradients between the day and night. Mars’s thin atmosphere produces a surface pressure of just 6 millibars, compared to 1 bar on Earth. At such low pressures, the boiling point of water plummets to leave all pure surface water frozen or vaporized.

Could Venus support liquid water on its surface?

The classical habitable zone around our sun marks where an Earth-like planet could support liquid water on the surface. Image credit: Cornell University. Unlike Mars, Venus has nearly the same mass as the Earth.

Are there other planets like Earth?

Finding Another Earth. A newly discovered exoplanet, Kepler-452b, comes the closest of any found so far to matching our Earth-sun system. This artist’s conception of a planetary lineup shows habitable-zone planets with similarities to Earth: from left, Kepler-22b, Kepler-69c, the just announced Kepler-452b, Kepler-62f and Kepler-186f.
