If only you would just present NASA with such an eloquently stated proposal, I'm confident that Europa will have yielded up all of its secrets by, or before, 2020!

One reason we might have not discovered aliens yet is because we are looking for them in the wrong place. We assume that aliens would live on planets orbiting a sun like we do. An advanced space faring alien species however would have progressed past the point of needing to live on a planet orbiting a sun. An advance civilization knowing the chaos of living in solar systems unpredictable nature would therefore find the safest place in the Universe to exist.
We need to learn a lot more about the characteristics of various stars before getting too optimistic. From a recent article:Wolf 1061 a Red Dwarf just 14 light years away could harbor life as one of the planets Wolf 1061c exists within the "Goldilocks Zone."]
LinkA small, cool star is emitting flares 10,000 times brighter than those ejected by the sun, a find that could be bad news for those hoping to find the galaxy filled with life.
If such emission is consistent across red dwarfs, it could mean bad news for the ability of life to evolve in the galaxy. Red dwarfs dominate the Milky Way, making up about three-fourths of all stars. Since NASA's Kepler telescope found planets around these worlds, the debate over whether or not they could host life has gone back and forth.
In order to hold liquid water on its surface, a condition necessary for life to evolve, a planet orbiting a dim red dwarf must lie significantly closer to its star than Earth lies to the sun. This region is known as the habitable zone. But its close proximity puts the planet at risk from stellar flares and coronal mass ejections, bursts of charged particles that stream out from a star. Stellar winds also carry charged particles away, potentially toward the planet.
If radiation reaches the surface of a planet, it can be damaging for any life growing there. Earth has a thick atmosphere that blocks most of the sun's rays, but the radiation that comes from orbiting very close to a red dwarf could tear away that type of protection.
How long would it take the engine in the article below to travel to Wolf 1061c?

Perception has nothing to do with reality. An alien ship will still exist regardless of whether you believe it to exist or not.

If it takes 92 years to get to alpha Centauri (as quoted in the article) at 4.37ly and Wolf 1061c is 13.8ly distant, 92*13.8/4.37 =290.5 years.
No, if it doesn't exist it isn't an alien ship.An alien ship will also continue to not exist regardless of whether you believe it to exist or not.
I know I wouldn't want to do it.A three hundred year sleep in a cryogenic chamber really is that bad.
In between galaxies. Although less gravity would be present there are rogue stars in the space between that would be able to power all of the systems needed to sustain the species that would live on large dockable stations that slingshot around a sun and because
of the lesser amount of gravity be able to travel faster than normal traveling around the space between looking for rogue comets and planets to harvest.
