CAPE CANAVERAL, Fla. — Thought the universe was crowded with 100 billion to 200 billion galaxies? Try 1 trillion or even 2 trillion galaxies and more.

That’s the latest census, reported Thursday.

An astrophysics professor at the University of Nottingham in England led the international team that came up with the mind-boggling estimate of 2 trillion galaxies in the universe. Professor Christopher Conselice said that represents a minimum tenfold increase.

In a phone interview, Conselice said he was surprised by the results. He anticipated two or three times more galaxies, perhaps, but “10 is quite high” and it could prove to be even greater.

The scientists based their galaxy head count on deep-space surveys already conducted by the Hubble Space Telescope and ground observatories. They turned the images into 3-D and used new mathematical models for the update.
