What will happen to Earth when, in a few billion years' time, the Sun is a hundred times bigger than it is today? Using the most powerful radio telescope in the world, an international team of astronomers has set out to look for answers in the star L2 Puppis. Five billion years ago, this star was very similar to the Sun as it is today.
New observations from the Hubble Space Telescope have revealed the intricate structure of the galaxy NGC 4696 in greater detail than ever before. The elliptical galaxy is a beautiful cosmic oddity with a bright core wrapped in system of dark, swirling, thread-like filaments.
Astronomers have observed the transit of a potentially Earth-like extrasolar planet known as K2-3d. While transits have previously been observed for thousands of other extrasolar planets, K2-3d is important because there is a possibility that it might harbor extraterrestrial life.
Scientists working on a revolutionary telescope project have harnessed the power of distributed computing from the UK's GridPP collaboration to tackle one of the Universe's biggest mysteries - the nature of dark matter and dark energy.
Frozen beneath a region of cracked and pitted plains on Mars lies about as much water as what's in Lake Superior, largest of the Great Lakes, a team of scientists has determined using data from NASA's Mars Reconnaissance Orbiter.
A team of astronomers has discovered a large number of dwarf galaxies in the early universe by using the gravitational lensing phenomenon, completing astronomers' census of star-forming galaxies in that epoch.
