Newbie question..

• by Mo0ky

  That's a star in the centre, correct? (due to the light 'beams'/refraction) But that guy to the right looks kind of cool. Can I classify the image regarding him? Or is it best to just mark it as a star/artefact?
  Thanks 😃
  Also.. Is creating new chat discussions like this the best way to ask these kinds of questions? I don't want to be spammy or anything is all.. Thanks friends

  Hi @Mo0ky and welcome to Galaxy Zoo 😃

  You are right - it is a foreground star 😃 Just classify as a star / artifact and move onto the next image!

  Only classify the object directly at the center, other galaxies in the image will have their own opportunity to be classified.

  The spikes around the star are called diffractions spikes - a type of optical artifact caused by the telescope itself. The missing pixels at the center are caused by over exposure or over saturation. The star was too bright for the CCD camera!

  Feel free to create discussions, that is what Talk is here for!
