Volcanic hydrogen spurs chances of finding exoplanet life
Hunting for habitable exoplanets now may be easier: astronomers report that hydrogen pouring from volcanic sources on planets throughout the universe could improve the chances of locating life in the cosmos.

Saturn's rings viewed in the mid-infrared show bright Cassini division
Researchers has succeeded in measuring the brightnesses and temperatures of Saturn's rings using the mid-infrared images taken by the Subaru Telescope in 2008. They reveal that, at that time, the Cassini Division and the C ring were brighter than the other rings in the mid-infrared light and that the brightness contrast appeared to be the inverse of that seen in the visible light. The data give important insights into the nature of Saturn's rings.

Mars More Earth-like than moon-like
Mars' mantle may be more complicated than previously thought, report researchers. Their report documents geochemical changes over time in the lava flows of Elysium, a major martian volcanic province.

Official naming of surface features on Pluto and its satellites: First step approved
The New Horizons flyby of Pluto and its satellites returned a scientific treasure trove of information about these distant and surprisingly complex worlds, showing a vast nitrogen glacier as well as ice mountains, canyons, cliffs, craters and more. Now the categories for official names have been approved and the name proposals can be submitted by the New Horizons team.

Neural networks promise sharpest ever images
Telescopes, the workhorse instruments of astronomy, are limited by the size of the mirror or lens they use. Using 'neural nets', a form of artificial intelligence, a group of Swiss researchers now have a way to push past that limit, offering scientists the prospect of the sharpest ever images in optical astronomy.

From rocks in Colorado, evidence of a 'chaotic solar system'
Plumbing a 90 million-year-old layer cake of sedimentary rock in Colorado, a team of scientists has found evidence confirming a critical theory of how the planets in our solar system behave in their orbits around the sun. The finding is important because it provides the first hard proof for what scientists call the ''chaotic solar system.'

NASA telescope reveals largest batch of Earth-size, habitable-zone planets around single star
NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.

Possible dark matter ties in Andromeda Galaxy
NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

Brightest neutron star yet has a multipolar magnetic field
Scientists have identified a neutron star that is consuming material so fast it emits more x-rays than any other. Its extreme brightness can only be explained if the star has a complex multipolar magnetic field, the researchers say.

Prediction: More gas-giants will be found orbiting Sun-like stars
New planetary formation models indicate that there may be an undiscovered population of gas giant planets orbiting around Sun-like stars at distances similar to those of Jupiter and Saturn.

Experiments call origin of Earth's iron into question
New research reveals that the Earth's unique iron composition isn't linked to the formation of the planet's core, calling into question a prevailing theory about the events that shaped our planet during its earliest years.

Mapping the family tree of stars
Astronomers are borrowing principles applied in biology and archaeology to build a family tree of the stars in the galaxy. By studying chemical signatures found in the stars, they are piecing together these evolutionary trees looking at how the stars formed and how they are connected to each other. The signatures act as a proxy for DNA sequences. It's akin to chemical tagging of stars and forms the basis of a discipline astronomers refer to as Galactic archaeology.

Why are there different 'flavors' of iron around the Solar System?
New work shows that interactions between iron and nickel under the extreme pressures and temperatures similar to a planetary interior can help scientists understand the period in our Solar System's youth when planets were forming and their cores were created.

Hubble spotlights a celestial sidekick
Technically, this picture is merely a sidekick of the actual object of interest -- but space is bursting with activity, and this field of bright celestial bodies offers plenty of interest on its own.

How disturbances interact with a dynamic space-time fabric: 'Field patterns' as a new mathematical object
Mathematicians propose a theoretical framework to understand how waves and other disturbances move through materials in conditions that vary in both space and time. The theory is called 'field patterns.'
