Nomads of the galaxy
Recently, a study was published in the Monthly Notices of the Royal Astronomical Society proposing planets simply adrift in space may be something of a common phenomenon. View More (2012-05-24)
The older we get, the less we know (cosmologically)

3-telescope interferometry allows astrophysicists to observe how black holes are fueled
By combining the light of three powerful infrared telescopes, an international research team has observed the active accretion phase of a supermassive black hole in the center of a galaxy tens of millions of light years away, a method that has yielded an unprecedented amount of data for such observations.

Massive black holes halt star birth in distant galaxies
Astronomers, using the European Space Agency's (ESA) Herschel Space Observatory, have shown that the number of stars that form during the early lives of galaxies may be influenced by the massive black holes at their hearts. View More (2012-05-10)

Queen's scientists discover black hole ripping apart star
Astronomers from Queen's University Belfast have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close. View More (2012-05-04)
Serious Blow to Dark Matter Theories?
The most accurate study so far of the motions of stars in the Milky Way has found no evidence for dark matter in a large volume around the Sun. View More (2012-04-19)
Black Holes Grow Big by Eating Stars
Most galaxies, including the Milky Way, have a supermassive black hole at their center weighing millions to billions of suns. View More (2012-04-03)
Fermi Observations of Dwarf Galaxies Provide New Insights on Dark Matter
There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of clusters of galaxies. View More (2012-04-03)
How black holes grow
A study led by a University of Utah astrophysicist found a new explanation for the growth of supermassive black holes in the center of most galaxies: they repeatedly capture and swallow single stars from pairs of stars that wander too close. View More (2012-04-02)
Clocking an accelerating universe: First results from BOSS
Some six billion light years ago, almost halfway from now back to the big bang, the universe was undergoing an elemental change. View More (2012-03-30)
Detection of cosmic effect may bring universe's formation into sharper focus
The first observation of a cosmic effect theorized 40 years ago could provide astronomers with a more precise tool for understanding the forces behind the universe's formation and growth, including the enigmatic phenomena of dark energy and dark matter. View More (2012-03-21)
VISTA stares deep into the cosmos
ESO's VISTA telescope has been trained on the same patch of sky repeatedly to slowly accumulate the very dim light of the most distant galaxies. View More (2012-03-21)
Astronomers using NASA's Hubble discover quasars acting as gravitational lenses
Astronomers using NASA's Hubble Space Telescope have found several examples of galaxies containing quasars, which act as gravitational lenses, amplifying and distorting images of galaxies aligned behind them. View More (2012-03-16)
The feeding habits of teenage galaxies
Astronomers have known for some time that the earliest galaxies were much smaller than the impressive spiral and elliptical galaxies that now fill the Universe. View More (2012-03-14)
Galaxy cluster hidden in plain view
A team of astronomers has discovered the most distant cluster of red galaxies ever observed using FourStar, a new and powerful near-infrared camera on the 6.5m Magellan Baade Telescope. View More (2012-03-07)
Galaxies get up close and personal
The Hercules galaxy cluster (also known as Abell 2151) lies about 500 million light-years away in the constellation of Hercules. View More (2012-03-07)
