Hubble Finds First Evidence of Water Vapor at Jupiter’s Moon Ganymede:

For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede.

[...] Scientists used new and archival datasets from NASA's Hubble Space Telescope to make the discovery, published in the journal Nature Astronomy.

Previous research has offered circumstantial evidence that Ganymede, the largest moon in the solar system, contains more water than all of Earth's oceans. However, temperatures there are so cold that water on the surface is frozen solid. Ganymede's ocean would reside roughly 100 miles below the crust; therefore, the water vapor would not represent the evaporation of this ocean.

Astronomers re-examined Hubble observations from the last two decades to find this evidence of water vapor.

    Even NASA cannot find any evidence that the election was stolen.

    Millennial astronomers know if you massage the data hard enough it'll give you what you want.

    We don't want any news about other planets or moons in the solar system. Only Mars! Tell us more about Mars! How many millimeters did the copter fly on Mars today? Send more robots to Mars! Mars is where it's at, baby, gotta get me more of that good ol' Mars Madness!
