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.
A team of researchers has presented a new model for the origin of Saturn's rings based on results of computer simulations. The results of the simulations are also applicable to rings of other giant planets and explain the compositional differences between the rings of Saturn and Uranus.
A new theoretical paper suggests that intentionally creating a 'traffic jam' out of a ring of several thousand ultracold atoms could enable precise measurements of motion. If implemented with the right experimental setup, the atoms could provide a measurement of gravity, possibly even at distances as short as 10 micrometers.
