Strange readings from a dead spacecraft reveal new evidence of water on Europa
Source: Los Angeles Times
A spacecraft wouldn't recognize evidence of a lunar geyser if that geyser hit it in the face. Luckily, the scientists on the ground did.
Researchers using 21-year-old data from NASA's Galileo spacecraft have found evidence of a plume of material coming from the surface of Jupiter's icy moon Europa. The discovery offers a new line of evidence for an ocean beneath its frozen crust and a promising path forward in the search for extraterrestrial life.
The results show that old data from long-gone spacecraft "hold a lot of secrets we haven't yet uncovered," said Lori Glaze, acting director of NASA's Planetary Science Division.
If humans are to look for life on other worlds, one of the first places scientists say they want to probe is cold, distant Europa. One of the four large moons circling our solar system's biggest planet, Europa's frigid shell is thought to hide a global ocean that may hold twice as much water as Earth.

From a practical standpoint it would give examples of evolution in environments different from our own.
Or show that life on Earth came from somewhere else.

Btw, the insidiously nurtured pop fad of contempt for science in favor of a factless world of demons and fear, manifested politically by Republican stuffing of governments and judiciaries at all levels with science deniers, has caused record numbers of people "with backgrounds in science, math, engineering and technology" to run for office this year.

(30,613 posts)One extraterrestrial microbe doubles the known number of times that life has evolved in the universe. It would be impossible at that point to argue that we're alone. If it happened twice, it happened billions of times in billions of ways.

(8,747 posts)Panspermia proposes that bodies such as comets transported life forms such as bacteria complete with their DNA through space to the Earth. Panspermia is the hypothesis that life exists throughout the Universe, distributed by space dust, meteoroids, asteroids, comets, planetoids, and also by spacecraft in the form of unintended contamination by microorganisms.
Panspermia is a hypothesis proposing that microscopic life forms that can survive the effects of space, such as extremophiles, become trapped in debris ejected into space after collisions between planets and small Solar System bodies that harbor life. Some organisms may travel dormant for an extended amount of time before colliding randomly with other planets or intermingling with protoplanetary disks. Under certain ideal impact circumstances (into a body of water, for example), and ideal conditions on a new planet's surfaces, it is possible that the surviving organisms could become active and begin to colonize their new environment. Panspermia is not meant to address how life began, just the method that may cause its distribution in the Universe.

(2,708 posts)I thought this was going to be an onion magazine satire. Since some european countries pronounce & spell Europe as Europa, I was getting ready for a chuckle about a new satellite 'finding water in amsterdamster', but alas, reading just splashed cold water on my dreams.
Finding water in amsterdamster, get it? dikes & all!
