Jakarta, CNBC Indonesia – Another sign of life found outside Earth. The discoveries of life’s chemicals are on Saturn’s moon Enceladus.
Scientists discovered these findings from NASA’s Cassini mission data. The mission studied Saturn and the moons that orbit it between 2004 and 2017.
NASA spacecraft are known to fly over Enceladus several times. The results found phosphorus in the moon.
“Phosphorus in the form of phosphate is essential for all life on Earth,” said lead study author and professor of planetary science at the Freie University Berlin, Frank Postberg. CNN InternationalFriday (28/7/2023).
He added that phosphorus is found in many things in living things. “It is essential for the manufacture of DNA and RNA, cell membranes and ATP for example. Life as we know it would not exist without phosphates”.
The finding of phosphorus is the first recorded discovery in the oceans outside of Earth. According to Postberg, the findings of the Cassini measurements are similar to those found in seawater.
“Cassini’s measurements leave no doubt that large amounts of these essential substances are present in seawater,” he said.
Phosphate findings on Enceladus are different from those found on Earth. Phosphate is contained mostly in the oceans.
“The important part of habitability is that we found phosphate dissolved in the oceans of Enceladus and available for the formation of potential life,” he said.
“In most cases, phosphate [di Bumi dan tempat lain di tata surya] It’s in rocky minerals, but on Enceladus, phosphate dissolves in large quantities as salt in the oceans.”
