The cores of several distant galaxies, spread out across roughly 1 billion light-years, appear to mysteriously align with one another. If confirmed, the new observations could be a hint of some unknown mechanism that shapes the largest structures in the universe.

Analysis of data from the European Space Agency’s Planck mission has found out some pretty cool new things about our universe, including:

– It’s older than we believed, at about 13.81 billion years.
– It’s expanding more slowly than we expected.
– It’s made up of 4.9 percent normal matter, 26.8 percent dark matter, and 68.3 percent dark energy.
– And finally, that it’s a tiny bit lopsided.

Cosmology is the study of the overall structure of the universe. Just what is the Universe? It is everything that exists. However, from Earth we cannot observe everything in the Universe. Some things are dark (brown dwarf stars, planets, and Dark Matter) and we cannot see them. Additionally, there are parts of the universe whose light has not yet reached us in this part of the Universe.
 And because light travels at a set speed we actually look back in time when we look into the cosmos. Astronomers observe some interesting structure in the Current Universe. That structure can tell us much about the History of the Universe. It can also tell us what we can expect for the Future of the Universe and beyond…
