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 galaxy had, says Eric Peng, lead author of the report that was published in the Astronomical Journal. In the case of Centaurus A, a galaxy 10 million light-years away, it must have collided with another galaxy before dominating the smaller one. This could also happen in our galaxy several billion years from now! Peng said, "When our galaxy merges with Andromedia Galaxy...the Milky Way's satellite galaxies...will also be involved"

My opinion on this article is that it's very nice. I learned something very new that I never even heard of before. I think that this article was well written and has all the facts clear with details. I think that this new discovery will shape the way we think about space and the galaxies. I was also startled when the article said that our galaxy will merge with another. I feel that the article also changed the way I think about space. Overall, the article was very nice, and I personally enjoyed reading it and learning about something new.
