Earth-sized planets in habitable zones are more common than previously thought
The number of potentially habitable planets is greater than previously thought, according to a new analysis by a Penn State researcher, and some of those planets are likely lurking around nearby stars.
Astronomers conduct first remote reconnaissance of another solar system
Researchers have conducted a remote reconnaissance of a distant solar system with a new telescope imaging system that sifts through the blinding light of stars. Using a suite of high-tech instrumentation ...
Auroras shine light on solar flares
(Phys.org) —Astrophysicists at the University of Glasgow are looking to the Northern and Southern Lights to expand our understanding of solar flares.
Modeling Jupiter and Saturn's possible origins
New theoretical modeling by Carnegie's Alan Boss provides clues to how the gas giant planets in our solar system—Jupiter and Saturn—might have formed and evolved. His work was published recently by the ...
Simple view of gravity does not fully explain distribution of stars in crowded clusters
(Phys.org)—Gravity remains the dominant force on large astronomical scales, but when it comes to stars in young star clusters the dynamics in these crowded environments cannot be simply explained by the ...
Astronomers suggest new telescopes could detect biomarker gasses in exoplanet atmospheres
MOND used to predict key property in Andromeda's satellites
Using modified laws of gravity, researchers from Case Western Reserve University and Weizmann Institute of Science closely predicted a key property measured in faint dwarf galaxies that are satellites of the nearby giant ...
New evidence indicates auroras occur outside our solar system
University of Leicester planetary scientists have found new evidence suggesting auroras – similar to Earth's Aurora Borealis - occur on bodies outside our solar system.
Black holes growing faster than expected
(Phys.org)—Astronomers from Swinburne University of Technology have discovered how supermassive black holes grow - and it's not what was expected.
Nearby dwarf galaxy and possible protogalaxy discovered
(Phys.org)—Peering deep into the dim edges of a distorted pinwheel galaxy in the constellation Ursa Major (the Great Bear), astronomers at Case Western Reserve University and their colleagues have discovered a faint dwarf ...
Spitzer and Hubble telescopes see weather patterns in brown dwarf
(Phys.org)—Astronomers using NASA's Spitzer and Hubble space telescopes have probed the stormy atmosphere of a brown dwarf, creating the most detailed "weather map" yet for this class of cool, star-like ...
Telescopes find evidence for asteroid belt around Vega
(Phys.org)—Astronomers have discovered what appears to be a large asteroid belt around the star Vega, the second brightest star in northern night skies. The scientists used data from NASA's Spitzer Space ...
Planets abound: Astronomers estimate that at least 100 billion planets populate the galaxy
(Phys.org)—Look up at the night sky and you'll see stars, sure. But you're also seeing planets—billions and billions of them. At least.
How white dwarfs mimic black holes
(Phys.org)—A remarkable observation by astronomers from the University of Southampton has been published in one of the world's foremost astrophysics research journals.
