More evidence appears to be one of the saturn’s months to secret life
Recent study Enceladus, one of Saturn’s months, revealed several organic compounds that have never been recorded before. The findings were published this month in the astronomy of nature, provide new marks on the inner chemical composition of this icy world, as well as a new hope that you could pound life.
The researchers analyzed data from the Cassini probe, which appeared in 1997. and studied Saturn and his moon to his destruction in 2017. year, Cassini collected data from the icy fragments from the Moon’s underground ocean into space.
Enceladus has been discovered in Saturn’s gravitational withdrawal by 274. It measures a diameter about 500 kilometers, which makes it a planet six-largest satellite. Although this month does not expire for its size, it is significant for its cryonolcanoes on Encladus South Pole, which has expelled water vapor and ice fragments. The plumps of expelled material can be expanded to almost 10,000 kilometers in length, which is more than a distance from Mexico to Patagonia, and some of this material rises into space. The farthest saturn’s main rings – his ring – primarily seems of ice thrown in the enceladus space.
It is believed that this material comes from the saline water chamber below the moon iceberg that is associated with its rocky core. It is possible that chemical reactions take place down, under high pressure and warm.
So far, most chemical analysis of ice from Enceladus was deposited in Saturn’s E ring. But during the fast flying month in 2008. Cassini was sufficient enough to sample freshly thrown fragments from Kriovolcan. New research work reaffirmed this data, confirming the presence of previously discovered organic molecules, as well as the detection of compounds previously undetected.
“Such compounds are of the intermediaries in the synthesis of more complex molecules, which could be potentially biologically relevant. However, these molecules,” Nozair Khawaja, the planetary scientist from Berlin and the leading author of the study, said for Reuters. The discovery significantly expands the range of confirmed organic molecules on encepladus.
The key is that the compounds appeared in freshly thrown particles, suggesting that they were formed within the moon-hidden ocean or in contact with their internal interfaces, not during travel via e-ring or exposure. This increases the hypothesis that the hydrothermal processes below the enSpoladus surface could generate rich organic chemistry. By combining this new research with previous studies, scientists have now found five out of six elements that are necessary for life-carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur disincludes satellite material.
Sam alone is not the discovery of life, nor biosignatures – signs of life. However, the research confirms that Enceladus has three basic conditions for life in the form: liquid water, energy source and essential elements and bodies. “Enceladus is, and it should be ranked, as the main target for researching residence and search whether there is life or not,” Khawaja said.

6,000 planets were found outside the solar system
Number Confirmed planets outside our solar system known as exoplains – rose to 6,000, said NASA. There is a great diversity in these distant worlds, the Space Agency says, with findings, including rocky planets, lion worlds and gas giants that include their stars.
Quite more discoveries is probably on the way. As a result of continuous monitoring of NASA’s Exoplanetic Science Institute (Nexss), more than 8,000 potential planets were identified and awaiting confirmation. It planned with future missions, including Nancy Grace Roman Space Telescope and the worldwide Observatory in the world, the American Space Agency hopes for more planets such as land and worlds with possible signs of life.
This turning point of 6,000 planets comes 30 years after the first exoplanet detected the orbit of the star similar to our sun. “This milestone represents the decades of cosmic research, who has managed and researching a company banning how humanity looked at the night sky,” Shawn Domagal-Goldman said, the acting of the Astrophysics headquarters in the statement. “Step by step, discovering to characterization, our mission built the foundations to respond to a fundamental question: are we ourselves?”
As the number of confirmed exoplanets increased, the scientific community could build a picture of the planet population through the universe. Researchers estimate that the rocky planets appear to be most common in the universe. They also discovered the planets of the size of Jupiter who is the Orbit closer to his star than Mercury on our sun or planets that have two stars. Some discovered worlds are covered with a lion; Others are surrounded by clouds of precious stones.
“Each of the different types of planets that we discover gives us the conditions of the conditions under which they can form and, in order to ultimately, how the usual planets like the country could and where we were supposed to look for,” Dawn Gelino, the Exoplanet Head of Explanet Investigation. “If we want to find out if we are alone in the universe, it’s all knowledge.”
Although the number of confirmed exoplanets reached 6,000, there are only about 100 that scientists could immediately observe. This is because the light from distant worlds is often so faints to merge into the light that is the mother star emitted. Detection methods are therefore usually indirect; Among the most common is the transit method that includes the detection of the planet by observing the IT orbit, which slides a short time because the planet passes in front of it from our perspective.
