From the Earth to the Moon: Resolving estimates of proto-Earth accretion with lunar-forming impact
A second look at supernovae light: Universe's expansion may be understood without dark energy
How did the universe begin?
28 new planets, 7 new brown dwarfs reported by California, Carnegie team
The world's largest and most prolific team of planet hunters announced the discovery of 28 new planets outside our solar system, increasing to 236 the total number of known exoplanets.

Cassini Image Shows Saturn Draped in a String of Pearls
Saturn appears dressed to the nines, "wearing" a strand of "pearls" in a stunning infrared image from the Cassini spacecraft that showcases a meteorological phenomenon.
Researchers Study Formation Of Chemical Precursors to Life
In just two years of work, an international research team has discovered eight new complex, biologically-significant molecules in interstellar space using the National Science Foundation's Robert C. Byrd Green ...
Mars' dust storms may produce peroxide snow
The planet-wide dust storms that periodically cloak Mars in a mantle of red may be generating a snow of corrosive chemicals, including hydrogen peroxide, that would be toxic to life, according to two new studies ...
A simple survey yields a cosmic conundrum
A survey of galaxies observed along the sightlines to quasars and gamma-ray bursts--both extremely luminous, distant objects--has revealed a puzzling inconsistency. Galaxies appear to be four times more common in the direction ...
Pre-life molecules present in comets
Evidence of atomic nitrogen in interstellar gas clouds suggests that pre-life molecules may be present in comets, a discovery that gives a clue about the early conditions that gave rise to life, according to researchers from ...
Cassini finds evidence for hydrocarbon lakes on Titan
The Cassini spacecraft, using its radar system, has discovered very strong evidence for hydrocarbon lakes on Titan. Dark patches, which resemble terrestrial lakes, seem to be sprinkled all over the high latitudes ...
Models show one nearby star system could host Earth-like planet
The steady discovery of giant planets orbiting stars other than our sun has heightened speculation that there could be Earth-type worlds in nearby planetary systems capable of sustaining life. Now researchers running computer ...
