On October 25, 2002, a group of John Hopkins University researchers spotted something unusual in their high-resolution telescope images. This was a totally unpredicted. Even Holland Ford, one of JHU's researchers, said, "One of the joys of science is unexpected discoveries". The huge blue arc was created 200 and 400 million years ago. This streak in the sky was created when the galaxy Centaurus A broke apart and took in its neighbor, sparking the formation of thick "arcs' of blue stars. Their original research was totally broken apart when they found these new halos. Ford said, "Although our pictures were taken for another project, we decided to search the data..."
These "galactic dinners" are the creators of the blue halos. Therefore, we can see that these arcs are like pieces of ancient time. Using these arcs, astronomers can figure out cosmic events that have shaped the universe. This is because the halos take a longtime to form, so the may preserve conditions that a......
