Two Trillion Galaxies and counting
The universe seems a little less lonely today.
Astronomers from the University of Nottingham conducted a new survey of
the universe’s galaxy population and concluded that previous estimates
lowballed the census by a factor of about 20. Using data from Hubble and
telescopes around the world, as well as a new mathematical model, they
estimate that there are ten times more galaxies in the observable
universe than we thought; previous estimates put the number of galaxies
in the universe at around 200 billion.
