There is water, that is, there is life. Europa - one of Jupiter's four moons - is becoming the latest candidate to nurture life in the solar system.
As reported, NASA held a press conference announcing an important discovery on Europa - one of Jupiter's four moons. Earlier, many people believed that the press conference would likely include information about aliens on it.
Sorry, there are no aliens. But in return, the potential for life on Europa is huge, as the Hubble telescope has recently snapped up a water- like image of more than 200,000 meters above the surface of this Jupiter satellite .
That said, below the surface of Europa is a huge underground ocean, and this amount of water has followed the geothermal vents soaring straight into the air.

Paul Hertz, director of astrophysics at NASA, said: "For a long time, mankind has been wondering about whether life exists somewhere? And we are fortunate to be born. "In the age of being able to answer that question. The truth is that life like Earth can be found anywhere, as long as it has water and nutrients."
"So, we're always interested in places with such characteristics. And it seems like Europa is the place. Today's results make us more confident that liquid water can appear on the surface of Europa, and we can study it without digging down the ice that is about kilometers deep on it. "
Additional observations still need to be made, but if this image is verified, Europa will be the second Moon in the Solar System that has the phenomenon of . spraying water has been discovered. Earlier, the Cassini spacecraft had snatched the water shot up on Enceladus' surface - Saturn's moon.
"The ocean on Europa is one of the hotspots that has the potential to come to life in our solar system, " said Geoff Yoder, NASA's scientific task manager . will provide us with many options for verifying the ability to sustain life here ".
Previously, experts suspected that below the Europa surface there was a huge ocean, with even twice the amount of water compared to Earth's oceans. However, this water is protected by a layer of super thick, super hard, and super cold ice.

The data from Hubble on Europa has been collected since January 2014, based on data from two Galileo and Voyager missions. As a result, NASA obtained a picture of a water column, spraying as high as 200km, then pouring it into the surface of Europa.
The team led by William Sparks from the Astronomical Observatory Science Institute (Baltimore) followed Europa every time it passed Jupiter. They realized that if there was really steam on Europa, it would be able to block Jupiter's light, and we would see this star have certain dark spaces.
The follow-up lasted 15 months, and the achievement was published, showing signs of steam on the surface of Europa, thereby turning Europa into the latest candidate to have life-sustaining potential in the Sun. system.
