Census Finds Universe Has Ten Times More Galaxies

By David Reneke

The universe has ten times more galaxies than previously thought, and the Earth may have had more than one moon.

Astronomers using data from the NASA/ESA Hubble Space Telescope and other telescopes have performed an accurate census of the number of galaxies in the universe, and concluded that there are at least 10 times as many galaxies in the observable universe as previously thought. The results have clear implications for our understanding of galaxy formation, and also help solve an ancient astronomical paradox – why is the sky dark at night?

A Habitable Planet May Be Just Around The Corner

By David Reneke

Astronomers have discovered the closest habitable planet outside our solar system, and discovered one of the biggest black holes ever.

Astronomers from the University of NSW have discovered the closest potentially habitable planet found outside our solar system so far, orbiting a star just 14 light years away. The planet, more than four times the mass of the Earth, is one of three that the team detected around a red dwarf star called Wolf 1061.

A New Spin on Star-Forming Galaxies

By Dave Reneke

Astronomers calculate that black holes at the heart of galaxies could swell to 50 billion times the mass of the Sun, and determine why some galaxies are “clumpy” rather than spiral in shape.
