5km thick ice crust sounds like it would be technologically impenetrable for the foreseeable future. Someone get Bruce Willis on the phone.
The best we could probably do is land a rover as near to one of the plumes as possible and pray for some microbial ETs to land on some sensors.
This video shows the 2 057 050 stars from the TGAS sample, which was published as part of the first data release of ESA's Gaia mission (Gaia DR1) on 14 September 2016, with the addition of 24 320 bright stars from the Hipparcos Catalogue that are not included in Gaia's first data release. The stars are plotted in Galactic coordinates and using a rectangular projection: in this, the plane of the Milky Way stands out as the horizontal band with greater density of stars.
The video starts from the positions of stars as measured by Gaia between 2014 and 2015, and shows how these positions are expected to evolve in the future, based on the proper motions from TGAS. The frames in the video are separated by 750 years, and the overall sequence covers 5 million years. The stripes visible in the early frames reflect the way Gaia scans the sky and the preliminary nature of the first data release; these artefacts are gradually washed out in the video as stars move across the sky.
The shape of the Orion constellation can be spotted towards the right edge of the frame, just below the Galactic Plane, at the beginning of the video. As the sequence proceeds, the familiar shape of this constellation (and others) evolves into a new pattern. Two stellar clusters – groups of stars that were born together and consequently move together – can be seen towards the left edge of the frame: these are the alpha Persei (Per OB3) and Pleiades open clusters.
Nah. The general idea for getting into Europa or enceludus is to use plutonium 239s heat generating capability to melt a hole through the icy crust.5km thick ice crust sounds like it would be technologically impenetrable for the foreseeable future. Someone get Bruce Willis on the phone.

Next thing you know they'll be materializing on space stations and walking the earth in nude sexy female form while souls are sucked up into space by a space job.Then, in time, the covering for the plutonium corrodes and cracks leaking radioactive material into the sea. The bacterial life mutates into super-intelligent and hostile alien life. They then fly over here in their UFOs and nuke Earth!
Serious question: could the U.S. alleviate it's heavy debt burden through external means? Asteroid mining is being laughed at in the politics thread, but could the U.S. exploit something external such as the moon or other off-planet resource?

I thought astronomy was the zodiac signs or whatever that people did their horoscopes and shit with... why is this thread all about space?
Not to be confused with Astronomy, the scientific study of celestial objects.
