Objects?

• by Ariaiyc_goingawayn0w

  Anyone know what's going on with the center galaxy and the two bright objects immediately to its upper left? Overlap? Are the two reddish objects close to each other?

  Two red objects are two red stars. The actual size of each star would be smaller than a pixel, so they would be further apart than you would think, assuming they are a binary pair and and not just line of sight.

  You can calcuate the distance between the two stars yourself, using this example

  website: http://chandra.harvard.edu/photo/scale_distance.html Example 2. If two stars in a star cluster 800 light years away are 1 arc minute apart, then using Equation (2) their separation in light years is calculated to be:
  S = (.00029) x (800) x 1 = .23 light years
