Spitzer measures rate of universe's expansion

Astronomers have come up with their most accurate measurement yet of the Hubble constant, the rate at which the universe is expanding.

Camera begins search for secret of dark energy

The newly-built Dark Energy Camera in Chile - the most powerful digital camera in the world - has captured its first images, as part of an effort to understand why the expansion of the universe is speeding up.

Future cosmologists doomed by expanding universe

We've arrived late for the cosmic show - too late for the best seat, says Harvard theorist Avi Loeb. He says the ideal time to study the cosmos was more than 13 billion years ago, just half a billion years after the Big Bang.

Survey reveals how dark energy shaped universe

After two years' work, the Sloan Digital Sky Survey (SDSS-III) has  measureed the precise distances of over a quarter of a million galaxies.

New calculation of the size of the universe

An Australian PhD student  has produced one of the most accurate measurements ever made of how fast the universe is expanding and thus how big it is. 

Dark energy fuels universe's expansion

After a five-year survey of 200,000 galaxies, astronomers believe they've confirmed that dark energy is driving our universe apart at an ever-accelerating rate.

No room left for fisheries to expand, survey shows

There's no  room on the planet to expand fisheries any further, according to a new study that tracks their growth since 1950.

Gravitational lens helps solve mystery of dark energy

Using a galaxy cluster as a magnifying lens, an international team of astronomers has used the NASA/ESA Hubble Space Telescope to examine distant regions of the universe.
