\n Enceladus, Saturn\u2019s mysterious moon that could support life, could be more geologically active than previously thought, according to a new study.<\/p>\n

The research, published in the scientific journal Icarus<\/a>, looked at new images from NASA\u2019s Cassini spacecraft and found the northern hemisphere of Enceladus has been resurfaced with ice.<\/p>\n

In 2005, Cassini observed that the southern hemisphere had more than 100 geysers shooting \u201cout enormous plumes of ice grains and vapor from an ocean that lies under the icy crust,\u201d according to a NASA statement. However, the new images point out it is happ<\/a>ening in the northern hemisphere as well.<\/p>\n

With its global ocean, unique chemistry and internal heat, Enceladus has become a promising lead in our search for worlds where life could exist.<\/p>\n

The researchers used Cassini\u2019s on-board Visual and Infrared Mapping Spectrometer (VIMS) to look at heat signatures on Enceladus and created a new map of the moon to come up with their findings.<\/p>\n

\u201cThe infrared shows us that the surface of the south pole is young, which is not a surprise because we knew about the jets that blast icy material there,\u201d said study co-author, Gabriel Tobie, VIMS scientist with the University of Nantes in France, in the statement.<\/a> \u201cNow, thanks to these infrared eyes, you can go back in time and say that one large region in the northern hemisphere appears also young and was probably active not that long ago, in geologic timelines.\u201d<\/p>\n

The geysers are believed to have caused the \u201ctiger stripes\u201d<\/a> on the moon, first spotted by NASA\u2019s Cassini spacecraft. They are evenly spaced fissures, approximately 81 miles long and 22 miles apart.<\/p>\n

It\u2019s unclear how the icy resurfacing occurred or when it occurred, but the statement suggests a couple of possible explanations. \u201cThe resurfacing in the north may be due either to icy jets or to a more gradual movement of ice through fractures in the crust, from the subsurface ocean to the surface,\u201d the statement from NASA JPL states.<\/p>\n

The Cassini spacecraft intentionally plunged itself into Saturn\u2019s atmosphere in September 2017.<\/a> It was launched in 1997<\/a> at a total cost of $3.9 billion ($2.5 billion in pre-launch costs and $1.4 billion in post-launch). It spent 13 years circling, studying and taking data of Saturn and its moons.<\/p>\n

In 2017, NASA found the presence of hydrogen<\/a> in its atmosphere, something Linda Spilker, Cassini project scientist at NASA\u2019s JPL, said at the time could be meaningful as a \u201cpotential source for energy from any microbes.\u201d<\/p>\n

One year later, scientists made a startling announcement<\/a> when they said they had found complex organic molecules, the \u201cbuilding blocks\u201d for life, on the moon. In 2019, researchers determined its ocean<\/a> is likely 1 billion years old, placing it in the sweet spot for supporting life.<\/p>\n

Enceladus is not the only celestial satellite of Saturn to intrigue scientists. In June, NASA announced<\/a> the latest mission in its New Frontiers program. Known as Dragonfly, the mission will explore Saturn\u2019s largest moon, Titan, which could potentially host extraterrestrial life.\n <\/div>\n
