Astronomers have come up with their most accurate measurement yet of the Hubble constant, the rate at which the universe is expanding.
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.
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.
After two years' work, the Sloan Digital Sky Survey (SDSS-III) has measureed the precise distances of over a quarter of a million galaxies.
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.
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.
There's no room on the planet to expand fisheries any further, according to a new study that tracks their growth since 1950.
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.
Globalfoundries has announced plans for a $3 billion expansion of its factories in New York and Germany.
