Some Pretty Cool Galaxies
Public star parties are a great place to show the wonders of the night sky to children and adults alike. One of the most frequently asked questions asked is, you guessed it, “how far can you see with this telescope”? In response the term light year is defined as a rounded off figure of ten trillion kilometres. Turning our instruments skywards to a faint smudge, we rattle off the estimated distance (in light years) we have previously read in books or found on web sites. With distances of nebulae and star clusters are listed in the thousands of light years category while residing in our Milky Way Galaxy, however, remote galaxies would be the correct answer.
