Scientists are currently unable to navigate deep space the way Columbus sailed and charted the New World or Lewis and Clark mapped the West.
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.
The universe began not as a Big Bang but rather like water freezing into ice, a team of theoretical physicists suggests.
The biggest-ever 3D map of the universe has been released, including more than 500,000 galaxies and 100,000 stars.
Dark energy is believed to make up approximately 70 percent of the current content of the universe.
Neutrons may be traveling from our universe into parallel worlds and back again, according to a new theory that explains a rather odd phenomenon.
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) may be the size of a refrigerator, but it will undoubtedly help astronomers discover some of the most interesting aspects of our 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.
A proposed new time-keeping system could make atomic clocks look positively erratic, staying accurate to one twentieth of a second over 14 billion years - the age of the universe.
Scientists at the University of California, Santa Cruz have used a NASA supercomputer to create what they say is the most accurate and detailed simulation of the universe ever.
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.
New observations have indicated that there are three times as many stars in the universe as previously believed.
Australian and British astrophysicists say they have found evidence that the laws of physics are different in different parts of the universe.
Theoretical physicist and official World's Cleverest Chap Stephen Hawking says there's no reason to think that God created the universe.
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.
Everything we know about the composition of the universe may be wrong, according to physicists.
Our entire universe may be located inside a wormhole, part of a black hole that lies within a much larger universe.
