[merged] Underground Ocean on Ganymede ?

NASA's Hubble Observations Suggest Underground Ocean on Jupiter's Largest Moon

NASA's Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter's largest moon. The subterranean ocean is thought to have more water than all the water on Earth's surface.

Identifying liquid water is crucial in the search for habitable worlds beyond Earth and for the search for life as we know it.

"This discovery marks a significant milestone, highlighting what only Hubble can accomplish," said John Grunsfeld, assistant administrator of NASA's Science Mission Directorate at NASA Headquarters, Washington, D.C. "In its 25 years in orbit, Hubble has made many scientific discoveries in our own solar system. A deep ocean under the icy crust of Ganymede opens up further exciting possibilities for life beyond Earth."

With a subsurface ocean, you could go to the beach without worrying about getting sunburned.

Pure scientific elegance and finesse, and scientific history in the making. Measure the movement of aurorae over Ganymede. Find that they undulate less than expected. Make a necessary connection to Ganymede's magnetic field, which has it's restlessness quelled by something. That something turns out to be a huge subsurface ocean, with its own induced magnetic field. Remarkable!

Maybe they'll find giant lobsters.

And probably Megalodon too..:whistle:

hey you know what would be fun finding out if any fish on earth can survive there and sending like at least 2 of each species that can there with a space ship, or at the weary least some tough bacteria, why should we look for alien life if we can make it, admit you so want to play god and do so

"Fun"?

You ever get idea they throw newly discovered facts around to get more funding? Sorta like Homeland, saying "we heard chatter", give us your rights.

No, but then that's probably because I base my ideas firmly in the real world of science, facts and evidence, not in the fantasy world of make believe and TV fiction.

In the real world NASA's budget is a fraction of what it was in the 1960s despite them have made discovery after discovery in the last few decades.

yeah, maybe not at first but in a millennium or so of evolution, besides tinkering with nature and creating alien life as a god, seems pretty fun to me

This is so cool! We keep discovering new information on our planets and their moons in our solar system. :tu: I'm doubtful there is life in Ganymede's oceanic world, because it needs the right combination of sunlight, oxygen and thermal heating.

Isn't that what they think in under our own moons surface?

Al least I remember hearing after placing seismometers on the moons surface then waiting one of the stages from apollo 12 to crash into the moon to take readings they found it caused a the moon to vibrate for nearly an hour like a tuning fork and attributed it to liquid water under the moons surface, sloshing like water after moving a fish tank.
