Very nice interactive showing the trajectory of Comet ISON. Move through space in 3d, start and stop the timeline and even switch to Earth perspective to see where the comet will be in the sky. I especially like that they show the planets rotating as they orbit the sun–because the timeline is moving many days per second, it’s like the planets are spinning tops.
If you just can’t stand simulations and want to see the real thing–that is, Earth, viewed from space–check this out:
With the aid of Russian space authorities, Vancouver-based UrtheCast (pronounced “earthcast”) will launch two cameras into orbit today (Nov. 25) with the immediate goal of streaming images of the Earth back home in near-real time.
