The Universe : Even bigger than before thought

According to astrophysicist Christopher J. Conselice (Nottingham University England) there are now two trillion galaxies. This is about 10 times as many galaxies as previously thought.

In the study astronomers formed three-dimensional models to measure the number of galaxies at different times from sky surveys by the Hubble Space Telescope and other instruments able to see far away, and about 13 billion years back. As not even the Hubble can see the oldest, faintest galaxies, the team also did some mathematical work to find two trillion galaxies.
