When you find something espcially beautiful in the sky and you want to share it with somebody else, you can right-click on its image in the context bar and choose Copy Shortcut. You can also do the same thing from the Finder (Explore.Show Finder) from the Research button. then you can paste it into an email, a blog post, or pretty much anything else.
For example, check out the almost-creepy filaments of the Crab Nebula, the galactic pair M81 and M82 (visible with a pair of binoculars!), or the rich set of images for the also binocular-baggable Lagoon Nebula.
That's a great tip Ethan. I'm amazed at how much functionality microsoft has put into this thing. I just hoped they would have advertised some of this "extra" functions somewhere, but I guess discovering them yourself is part of the experience.
