HUBBLE mostly artifact?

• by Tepjes

  is it normal for most of the hubble pictures, that you can only see clumpy pixels? I always classify these as artifact... is this the correct way to classify these?

  This is not an artifact, but it is a faint galaxy !

  so how to classify? "smooth", "completely round", "neither" is the correct way to follow for this object?

  Just answer the questions as well as you can.
  These faint ones are very difficult!
  Just give it your best shot!

  ok. thank you for your help Elisabeth! The hubble-pictures are always the most difficult indeed. and maybe one more question if I may, how would you describe "tidal debris", because I find it's difficult to translate to dutch... 😃

  tidal debris is a part of galaxy torn away from its galaxy by gravity of other galaxy forming a path of 'debris' - visible as a tail or other structure extending from the galaxy
