This is a jellyfish UFO. They are less common than the flying disks that are often seen, but still many have argued that they are not ships, but living, intelligent beings. If thats true, then they probably can travel though space without the need of a spacecraft. Similar Jellyfish UFOs have been seen during spacewalks on the space station live cam.

I walked with my girlfriend and I saw this silver orb and took a photo. I didn't know what it was at the time. Object hovered in the sky. I went home again the next day and didn't see it again.
