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.
An international team, with participation from the University of Bern, has produced the first map of clouds on an exoplanet using the Kepler Space Telescope. Studying the atmospheres of exoplanets is the path towards ultimately identifying life elsewhere in the Universe. Understanding the role of clouds in exoplanet atmospheres is a necessary ingredient in the cosmic hunt for life.
Astronomers have uncovered the strange case of a neutron star with the peculiar ability to transform from a radio pulsar into an X-ray pulsar and back again. This star's capricious behavior appears to be fueled by a nearby companion star and may give new insights into the birth of millisecond pulsars.
In the already complicated science of what creates -- and causes constant change in -- two giant doughnuts of radiation surrounding Earth, researchers have added a new piece of information: Some of the electrons reach such enormous energies that they are driven by an entirely different set of physical processes.
The densest galaxy in the nearby Universe may have been found. Packed with an extraordinary number of stars, this unusual galaxy is providing astronomers with clues to its intriguing past and how it fits into the galactic evolutionary chain.
More than 83,000 volunteer citizen scientists. Over 16 million galaxy classifications. Information on more than 300,000 galaxies. This is what you get when you ask the public for help in learning more about our universe.
Two million years ago a supermassive black hole at the heart of our galaxy erupted in an explosion so immensely powerful that it lit up a cloud 200,000 light years away, a team of researchers led by the University of Sydney has revealed.
