Distant moons may harbor life
Researchers have identified more than 100 giant planets that potentially host moons capable of supporting life. Their work will guide the design of future telescopes that can detect these potential moons and look for tell-tale signs of life, called biosignatures, in their atmospheres.

The true power of the solar wind
The planets and moons of our solar system are continuously being bombarded by particles from the sun. On the Moon or on Mercury, the uppermost layer of rock is gradually eroded by the impact of sun particles. New results show that previous models of this process are incomplete. The effects of solar wind bombardment are much more drastic than previously thought.

Diamond dust shimmering around distant stars
Some of the tiniest diamonds in the universe -- bits of crystalline carbon hundreds of thousands of times smaller than a grain of sand -- have been detected swirling around three infant star systems in the Milky Way. These microscopic gemstones are neither rare nor precious; they are, however, exciting for astronomers who identified them as the source of a mysterious cosmic microwave 'glow' emanating from several protoplanetary disks in our galaxy.

Minerology on Mars points to a cold and icy ancient climate
The climate throughout Mars' early history has long been debated -- was the Red Planet warm and wet, or cold and icy? New research published in Icarus provides evidence for the latter.

NASA finds ancient organic material, mysterious methane on Mars
NASA's Curiosity rover has found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life, as well as new evidence in the Martian atmosphere that relates to the search for current life on the Red Planet.

Evolution of nebula surrounding symbiotic star R Aquarii
Scientists have published a detailed study of the evolution of the nebula surrounding the symbiotic star R Aquarii. The study employed observations from telescopes at the Roque de los Muchachos Observatory, La Palma, and Chile taken over the course of more than two decades.

One of the most massive neutron stars ever discovered
Using a pioneering method, researchers have found a neutron star of about 2.3 Solar masses -- one of the most massive ever detected.

Multiple alkali metals in unique exoplanet
Scientists have observed a rare gaseous planet, with partly clear skies, and strong signatures of alkali metals in its atmosphere.

How solar prominences vibrate
Researchers have cataloged around 200 oscillations of the solar prominences during the first half of 2014. Its development has been possible thanks to the GONG network of telescopes, of which one of them is located in the Teide Observatory.

System with three Earth-sized planets discovered
Today marks the discovery of two new planetary systems, one of them hosting three planets with the same size of the Earth.

Discovery of clusters of galaxies in the early universe
Until now astronomers thought that these phenomena occurred 3,000 million years after the Big Bang, but this new result shows that they were already happening when the Universe was 1,500 million years old.

How do you weigh a galaxy? Especially the one you're in?
Pinning down the mass of a galaxy may seem like an esoteric undertaking, but scientists think it holds the key to unraveling the nature of the elusive, yet-to-be-seen dark matter, and the fabric of our cosmos. A new technique promises more reliable estimates of the masses of galaxies.

Tumultuous galaxy mergers better at switching on black holes
A new study finds that violent crashes may be more effective at activating black holes than more peaceful mergers.

New data-mining technique offers most-vivid picture of Martian mineralogy
A team of scientists have revealed the mineralogy of Mars at an unprecedented scale, which will help them understand the planet's geologic history and habitability. Understanding the mineralogy of another planet, such as Mars, allows scientists to backtrack and understand the forces that shaped their formation in that location.
