Some space satellite was able to find 7 different supernovas, it is impressive to have that many supernovas in 1 galaxy. The galaxy was Arp 220, Arp is 250 Million light years away. It is know that Arp 220 formed from the merger of two smaller galaxies and is well known to host a very intense burst of star formation, easily seen in visible wavelengths.Arp 220 Is causing many star deaths.Each of the supernovae found in Arp 220 spans less than a light-year, and at such a great distance, each radio signal covers an angle in the sky less than 0.5 milliarcseconds across, Batejat said.
Reflection:
1.How could this be good or bad for the society? It does not affect the humans. It affects the stars because ARP 220has some special explosives.
2.Why did you chose this article. I thought it amazing that people could go 250 million light years away and that there are 7 supernovas in a galaxy.
3.How did you find it? I was looking on the front page of National Geo and I thought it was pretty cool.
4.What did you learn? I learned that there can be more then 7 supernovas in a galaxy and that the galaxy ARP220 exists

Alex please make sure that you include the link to the website. Your summary was good, but you needed some more details perhaps about how they found this galaxy. What tools were they using?
