Astronomers using Herschel have detected massive debris discs around two nearby stars hosting low-mass planets. The discovery suggests that debris discs may survive more easily in planetary systems without very massive planets.

Astronomers have discovered a 'bridge' of hot gas connecting the galaxy clusters Abell 399 and 401. At least part of this gas might derive from the warm-hot intergalactic medium - the elusive web of gaseous filaments pervading the Universe.

By combining the power of the NASA/ESA Hubble Space Telescope, NASA's Spitzer Space Telescope and one of nature's zoom lenses, astronomers have found what is probably the most distant galaxy yet seen in the Universe. The object offers a peek back into a time when the Universe was only 3 percent of its present age of 13.7 billion years.

High above the main body of Mars' atmosphere is a region of weakly ionised gas, known as the ionosphere. New studies, based on observations from Mars Express, show that the dayside ionosphere is more variable and more complex than previously thought.

Data from INTEGRAL and XMM-Newton have helped astronomers study how neutron stars accrete mass in highly obscured X-ray binaries. The results suggest a new method to estimate the mass of neutron stars.

Astronomers using the NASA/ESA Hubble Space Telescope have obtained a remarkable new view of a whopper of an elliptical galaxy, with a core bigger than any seen before. There are two intriguing explanations for the puffed up core, both related to the action of one or more black holes, and the researchers have not yet been able to determine which...

Astronomers using Hubble have studied a giant filament of dark matter in 3D for the first time. Extending 60 million light-years from one of the most massive galaxy clusters known, the filament is part of the cosmic web that constitutes the large-scale structure of the Universe.
