  • The comet and the galaxy

    This refers to a recent addition in the hotspots by BRUNO (The Comet and the Galaxy) which I found interesting. I thought that comets only gained a visible "tail" when near a sun so if this is a comet where did it's tail come from. It doesn't seem close to any large star. Does this mean that it is an object that perhaps is moving a lot faster than the stars and thus shows as appearing to have a tail. I assume that these photos are taken over a long period of time and thus moving objects show as strips of light rather than spots.

    Who says it's not close to the Sun?

      Or close to a sun?

        Would the tail be that large if it was close to a star other than our sun? I would have thought that the star it was around would have to be much larger and visible as well.

          It's definitely the Sun! You would not be able to see it if it was another Star because Comets in other Systems are far to small/too distant to be seen.

            May be it's possible to know the name of the comet from the date of the observation.

              I noticed one website with what appears to be the same comet listing it as Linear RX14 C2000,

              although most places seem to have references to Linear RX14 C2001 and not 2000.

                Yes, it is.
                Thank you Murgy.

                  Maybe somebody can help me find out what the things are at these coordinates.

                  They look like just massive areas of dust but I don't think they're nebulae. I'm pretty sure they aren't galaxies because they don't have a bright area in them like the center of a galaxy.
                  Any ideas?
