The older we get, the less we know (cosmologically)
The universe is a marvelously complex place, filled with galaxies and larger-scale structures that have evolved over its 13.7-billion-year history. View More (2012-05-23)
Herschel Space Observatory study reveals galaxy-packed filament
A McGill-led research team using the Herschel Space Observatory has discovered a giant, galaxy-packed filament ablaze with billions of new stars. View More (2012-05-18)
Baby galaxies grew up quickly
Baby galaxies from the young Universe more than 12 billion years ago evolved faster than previously thought, shows new research from the Niels Bohr Institute. View More (2012-05-17)
A deeper look at Centaurus A
Centaurus A, also known as NGC 5128, is a peculiar massive elliptical galaxy with a supermassive black hole at its heart. View More (2012-05-16)
Free-floating planets in the Milky Way outnumber stars by factors of thousands
A few hundred thousand billion free-floating life-bearing Earth-sized planets may exist in the space between stars in the Milky Way. View More (2012-05-11)
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)
5-limbed brittle stars move bilaterally, like people
It appears that the brittle star, the humble, five-limbed dragnet of the seabed, moves very similarly to us. View More (2012-05-10)
Hubble observes a dwarf galaxy with a bright nebula
The starry mist streaking across this image obtained by the NASA/ESA Hubble Space Telescope is the central part of the dwarf galaxy known as NGC 2366. View More (2012-05-10)
VISTA views a vast ball of stars
Globular clusters are held together in a tight spherical shape by gravity. In Messier 55, the stars certainly do keep close company: approximately one hundred thousand stars are packed within a sphere with a diameter of only about 25 times the distance between the Sun and the nearest star system, Alpha Centauri.

One Supernova Type, Two Different Sources
The exploding stars known as Type Ia supernovae serve an important role in measuring the universe, and were used to discover the existence of dark energy. View More (2012-05-08)
Honing in on supernova origins
Type Ia supernovae are important stellar phenomena, used to measure the expansion of the universe. But astronomers know embarrassingly little about the stars they come from and how the explosions happen. View More (2012-05-08)
UF astronomer: Some giant planets in other systems most likely to be alone
"Hot Jupiter-type" planets are most likely to be alone in their systems, according to research by a University of Florida astronomer and others, made public today. View More (2012-05-08)
Four white dwarf stars caught in the act of consuming 'earth-like' exoplanets
University of Warwick astrophysicists have pinpointed four white dwarfs surrounded by dust from shattered planetary bodies which once bore striking similarities to the composition of the Earth. View More (2012-05-04)
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)
Sifting through dust near Orion's Belt
Dust may sound boring and uninteresting - the surface grime that hides the beauty of an object. But this new image of Messier 78 and surroundings, which reveals the submillimetre-wavelength radiation from dust grains in space, shows that dust can be dazzling. View More (2012-05-03)
Rogue stars ejected from the galaxy are found in intergalactic space
It's very difficult to kick a star out of the galaxy. In fact, the primary mechanism that astronomers have come up with that can give a star the two-million-plus mile-per-hour kick it takes requires a close encounter with the supermassive black hole at the galaxy's core. View More (2012-05-01)
NASA's Chandra sees remarkable outburst from old black hole
An extraordinary outburst produced by a black hole in a nearby galaxy has provided direct evidence for a population of old, volatile stellar black holes. View More (2012-05-01)
Record-Breaking Radio Waves from Ultra-Cool Star
Penn State University astronomers using the world's largest radio telescope, at Arecibo, Puerto Rico, have discovered flaring radio emissions from an ultra-cool star, not much warmer than the planet Jupiter, shattering the previous record for the lowest stellar temperature at which radio waves were detected.

A cluster within a cluster
NGC 6604 is the bright grouping towards to the upper left of the image. It is a young star cluster that is the densest part of a more widely scattered association containing about one hundred brilliant blue-white stars. View More (2012-04-25)
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)
