The possibility of liquid water establishes the possible existence of life on faraway planets. It suggests that the temperature range might also be within the tolerable range for Earth-like lifeforms.
Of all the major and minor planets of our solar system, only Earth has liquid water, and it is the basis for all lifeforms that we know of. Among planetary bodies, only Jupiter's moon Europa is thought to have water, albeit under a thick layer of ice. On Mars, water might also exist deep underground, but this is unconfirmed.
The discover of water on Mars has some significance to scientists. Even though the planet is very hot due to its proximity to the Sun, the presence of water signifies the possibility of life.
scientists did find water on the moon on November 13, 2009
Water has been known to man since ancient times therefore it was not discovered by scientists.
Frozen water was discovered.
Humans can currently live on Earth, as it provides the necessary conditions for human life such as oxygen, water, and suitable temperature. There are ongoing efforts to explore the possibility of living on other planets like Mars, but at present, Earth is the only known planet where humans can live.
They discovered a significant amount of water in the Moon's Cabeus crater
Mars
Scientists get excited when water is found elsewhere in the universe because water is essential for life as we know it. The presence of water on other planets or moons raises the possibility of finding microbial life or even more complex forms of life. It also provides insights into the potential habitability of these other celestial bodies.
Scientists have recently discovered frozen water on the moon, and on Jupiter's moon of Europa
Mars scientists found water on. Mars
Mars. Or, at least, that is what the stereotype is, because scientists are finding water.
There is no water on Mars because the planet is too cold to support water. Liquid isn't stable on the planet's surface but scientists have discovered that at one time, water was plentiful.
