The nearby star system Fomalhaut - of special interest for its unusual exoplanet and dusty debris disk - has been discovered to be not just a double star, as astronomers had thought, but one of the widest triple stars known.
A small satellite designed and built by a team of University of Colorado Boulder students to better understand how atmospheric drag can affect satellite orbits was successfully launched from Vandenberg Air Force Base in California Sunday morning.
The final antenna for the Atacama Large Millimeter/submillimeter Array (ALMA) project has just been handed over to the ALMA Observatory. The 12-metre-diameter dish was manufactured by the European AEM Consortium and also marks the successful delivery of a total of 25 European antennas.
Using a telescope in Antarctica and ESA's Herschel space observatory, astronomers have made the first detection of a subtle twist in the relic radiation from the Big Bang, paving the way towards revealing the first moments of the Universe's existence.
A new study reveals that according to observations made by the NASA rover Curiosity, the surface layer of the Gale crater near the Martian equator has a water content of about two percent, which is at the lower end of previous estimates.
A black hole. A simple and clear concept, at least according to the hypothesis by Roy Kerr, who in 1963 proposed a 'clean' black hole model, which is the current theoretical paradigm. From theory to reality things may be quite different. According to a new research, black holes may be much 'dirtier' than what Kerr believed.
Google Lunar XPRIZE has announced the line-up for its Judging Panel: eight international experts with experience from iconic space missions including Apollo, the Hubble Space Telescope, the Huygens probe to Titan, the Swift gamma-ray burst mission and the Curiosity Mars rover.
A team of Caltech-led scientists reports its analysis of a surprisingly Earth-like martian rock, discovered by the Mars Science Laboratory rover Curiosity, that offers new insight into the history of Mars's interior and suggests parts of the Red Planet may be more like our own than we ever knew.
Scientists have provided the most comprehensive details yet of the journey energy from the sun takes as it hurtles around Earth's magnetosphere. Understanding the changes energy from the sun undergoes as it travels away and out into space is crucial for scientists to achieve their goal of some day predicting the onset of space weather that creates effects such as the shimmering lights of the aurora or interruptions in radio communications at Earth.
The quest for evidence of life on Mars could be more difficult than scientists previously thought. Researchers detail the investigation of a chemical in the Martian soil that interferes with the techniques used by the Curiosity rover to test for traces of life. The chemical causes the evidence to burn away during the tests.
For astrophysicists, the interplay of hydrogen - the most common molecule in the universe - and the vast clouds of dust that fill the voids of interstellar space has been an intractable puzzle of stellar evolution.
