The interaction between the moon's plumes and Saturn's ring system was explored with Webb

Enceladus, a small, icy moon of hisSaturn— is one of the most interesting objects in the search for signs of life beyond our planet.

Beneath an ice crust lies a global saltwater ocean. Jets, supplied by this ocean, erupt from the surface of the moon and power the entire Saturn system.NASA'smallJames Webb Space TelescopeThe long-awaited first look at this oceanic world is already revealing surprising new details about the moon, including a jet plume of water vapor more than 20 times the size of the moon.

Webb Space Telescope maps surprisingly large plume coming from Saturn's moon Enceladus

A plume of water vapor from Saturn's moon Enceladus that stretches more than 6,000 miles -- nearly the distance between Los Angeles, California, and Buenos Aires, Argentina -- was detected by researchers using NASA's James Webb Space Telescope. Not only is it the first time such water emission has been observed at such a great distance, but Webb is also giving scientists a direct look, for the first time, at how this emission powers the water supply for the entire Saturn and ring system.

An ocean world about 4% the size of Earth, with a diameter of just 313 miles, Enceladus is one of our solar system's most exciting science targets in the search for life beyond Earth. Between the moon's icy outer crust and its rocky core lies a global reservoir of salty water. The geyser-like volcanoes spew streams of ice particles, water vapor, and organic chemicals from cracks in the moon's surface informally called "tiger stripes."

In the past, observatories hadaircraft mapped hundreds of milesfrom the lunar surface, but Webb's extraordinary sensitivity reveals a new story.

Researchers using NASA's James Webb Space Telescope recently discovered a plume extending from the moon's south pole more than 20 times the size of the moon. This animation shows how the moon's water columns feed the planet's torus. Analyzing Webb's data, astronomers have determined that about 30 percent of the water remains in this torus, with the other 70 percent escaping to feed water to the rest of the Saturn system.

“When I looked at the data, at first, I thought I must be wrong. It was so shocking to detect a water column more than 20 times the size of the moon,” said lead author Geronimo Villanueva of NASA's Goddard Space Flight Center in Greenbelt, Maryland. "The water column extends far beyond its release area at the South Pole."

Wing length was not the only feature that piqued the researchers' interest. The speed at which the water vapor gushes out, about 79 gallons per second, is also particularly impressive. At that rate, you could fill an Olympic-sized pool in just a few hours. By comparison, doing it with a garden hose on Earth would take over 2 weeks.

HemessThe orbiter spent more than a decade exploring the Saturn system and not only imaged Enceladus' plumes for the first time, but flew directly through them and took samples of what they were made of. While Cassini's position within the Saturn system provided invaluable information about this distant moon, Webb's unique Sun-Earth viewLagrange point 2a million miles from Earth, combined with the remarkable sensitivity of the Integrated Field Unit (see video below) on the NIRSpec (Near Infrared Spectrograph) instrument, offers new context.

“Enceladus' orbit around Saturn is relatively fast, just 33 hours. As it orbits Saturn, the moon and its jets are basically spitting water, leaving an almost donut-like halo in its wake,” Villanueva said. "In Webb's observations, not only was the plume huge, but there was water absolutely everywhere."

This fuzzy donut of water that appeared 'everywhere', described as a ring, sits alongside Saturn's outermost and widest ring: the dense 'E Ring'.

Webb's observations directly demonstrate how clouds of water vapor from the moon feed the torus. Analyzing Webb's data, astronomers have determined that about 30 percent of the water remains in this torus, with the other 70 percent escaping to feed the rest of Saturn's water system.

For years to come, Webb will serve as the primary observation tool for the ocean moon Enceladus, and Webb's discoveries will help inform future solar system satellite missions that will seek to explore the depth of the subsurface ocean, the thickness of the ice crust and further.

NASA's James Webb Space Telescope's extraordinary sensitivity and highly specialized instruments are revealing details about how one of Saturn's moons supplies water to the ringed planet's entire system. Enceladus, a leading candidate in the search for life elsewhere in our solar system, is a small moon about 4% the size of Earth. New images from Webb's NIRSpec (Near Infrared Spectrograph) have revealed a plume of water vapor erupting from Enceladus' south pole that stretches more than 20 times the size of the moon. The Integrated Field Unit (IFU) in NIRSpec also provided information on how Enceladus' water is fed into the rest of the environment.
Enceladus orbits Saturn in just 33 hours, and as it does so, it sprays water and leaves a torus, or "doughnut," of material in its wake. This bull is depicted in the above chart in light blue.
The Webb IFU is a combination camera and spectrograph. During an IFU observation, the instrument captures an image of the field of view along with individual spectra of each pixel in the field of view. IFU observations allow astronomers to investigate how properties (composition in this case) vary from place to place in a region of space.
The unique sensitivity of the Webb IFUs allowed the researchers to detect many streaks of water coming from the torus around Enceladus and the plume itself. This simultaneous collection of spectra from the plume and ring allowed the researchers to better understand their intimate relationship. In this spectrum, the white lines are the Webb data, and the best water emission models are overlaid in different colors: purple for the plume, green for the central region of the moon, and red for the surrounding torus. .

"Right now, Webb provides a unique way to directly measure how water evolves and changes over time in Enceladus' massive plume, and as we see here, we'll even make new discoveries and learn more about the composition of the underlying ocean," he added. co-author Stefanie Milam at NASA Goddard. "Because of Webb's wavelength coverage and sensitivity and what we've learned from previous missions, we have a new window of opportunity in front of us."

Webb's observations of Enceladus were completed as part of the Guaranteed Time Observing (GTO) 1250 program. The original goal of this program is to demonstrate Webb's capabilities in a specific area of ​​science and lay the foundation for future study.

"This program was essentially a proof of concept after many years of developing the observatory, and it's exciting that all this science has already come out of a fairly short observation time," said Heidi Hammel of the Association of Universities for Research in Astronomy, Webb . Interdisciplinary Scientist and GTO Program Manager.

They are mainly made of water-ice and rock which is mostly odourless…. Enceladus plumes are composed of volatile gases, water vapour, carbon dioxide and carbon monoxide – all odourless….

How deep is the ocean on Enceladus? ›

The ocean is about 25 miles/40km deep—according to NASA's Cassini probe—which is vastly deeper than Earth's ocean. “The pressure and temperature differences between the Enceladus ocean floor and the ice cap above must be tremendous,” writes astrobiologist Dr.

Could Enceladus be terraformed? ›

Terraforming is impossible because Enceladus cannot support an atmosphere. Paraterraforming could be possible for limited areas, but on a large scale, quakes will destroy the glasses, while falling ice will cover any surface.

Why could Enceladus support life? ›

Enceladus is one of the prime targets in the search for life in the solar system. Observations made by the Cassini spacecraft show that this small moon of Saturn has an ice-covered water ocean that erupts into space, forming a plume that contains almost all of the basic requirements of terrestrial life.

What is the future mission to Enceladus? ›

Can you land on Enceladus? ›

Enceladus has about a hundredth of the gravity on Earth, so landing should be relatively easy compared to Mars. It will then stay on the surface for a couple of years at least, occasionally changing position, to take (likely much larger) samples of that plume material that have fallen back.

What kind of life could exist on Enceladus? ›

The data also reflected generous amounts of carbon dioxide and methane (CH4), both of which told us that methane-based life forms or methanogens could exist around hydrothermal vents on Enceladus.

Does Enceladus have more water than Earth? ›

He has ranked the worlds by how much liquid water they have. Ranking from least to most, the list includes: Enceladus, Triton, Dione, Pluto, Earth, with Europa, Callisto, Titan and Ganymede have the most liquid water by volume. Jupiter's moon Ganymede has 46%, and Europa has 16% liquid water by volume.

Is Enceladus Dead? ›

Clearly, Enceladus was no dead world. It was active. A moon so small and so far from the sun had no business harboring liquid water. Scientists thought that the water cloud above Enceladus might be produced by water evaporating from the fissures via a surface process similar to what happens on a comet.

How long is a day on Enceladus? ›

One day on Enceladus is equal to 1.37 Earth days, or one day, 8 hours, and 53 minutes. This is the same amount of time it takes to complete an orbit around Saturn.
