This Hubble diagram was produced using the Online Version of the Supernovae Lab. You might notice that two points are far below the "best fit line." We could guess that the supernovae have been dimmed by dust in the line of sight, making them appear dimmer and therefore farther away. Astronomers have a complicated way to correct for this, but we could simply remove them from our graph, resulting in a graph that looks like this:
From this graph I calculated a Hubble Constant of 58km/s/Mpc and an Age of the Universe of 16.8 billion years. These values fall into the range of accepted values for the Hubble constant and age of the universe...at least within our limits for this lab and for 1999.
