Monster galaxies gain weight by eating smaller neighbors

Research to be published this Friday shows that massive galaxies in the universe have stopped making their own stars and are instead 'snacking' on nearby galaxies. Astronomers looked at more than 22,000 galaxies and found that while smaller galaxies are very efficient at creating stars from gas, the most massive galaxies are much less efficient at star formation, producing hardly any new stars themselves, and instead grow by eating other galaxies.

Miranda: An icy moon deformed by tidal heating

Miranda, a small, icy moon of Uranus, is one of the most visually striking and enigmatic bodies in the solar system. Despite its relatively small size, Miranda appears to have experienced an episode of intense resurfacing that resulted in the formation of at least three remarkable and unique surface features - polygonal-shaped regions called coronae.

Unravelling the mysteries of the Venusian atmosphere (w/video)

Underscoring the vast differences between Earth and its neighbor Venus, new research shows a glimpse of giant holes in the electrically charged layer of the Venusian atmosphere, called the ionosphere. The observations point to a more complicated magnetic environment than previously thought - which in turn helps us better understand this neighboring, rocky planet.

NASA research gives guideline for future alien life search

Astronomers searching the atmospheres of alien worlds for gases that might be produced by life can't rely on the detection of just one type, such as oxygen, ozone, or methane, because in some cases these gases can be produced non-biologically, according to extensive simulations by researchers in the NASA Astrobiology Institute's Virtual Planetary Laboratory.

Lurking bright blue star caught

Astronomers have found evidence of a hot binary companion star to a yellow supergiant star, which had become a bright supernova. Its existence had been predicted by the team. This finding provides the last link in a chain of observations that have so far supported the team's theoretical picture for this supernova.
