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)
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.

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)
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.

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)
Black hole caught red-handed in stellar homicide
Astronomers have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close. View More (2012-05-03)
Black Hole Caught Red-Handed in a Stellar Homicide
Astronomers have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close. NASA's Galaxy Evolution Explorer, a space-based observatory, and the Pan-STARRS1 telescope on the summit of Haleakala in Hawaii were among the first to help identify the stellar remains.

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.

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)
Some Stars Capture Rogue Planets
New research suggests that billions of stars in our galaxy have captured rogue planets that once roamed interstellar space. View More (2012-04-18)
Hubble's panoramic view of a turbulent star-making region
Several million young stars are vying for attention in a new NASA Hubble Space Telescope image of a raucous stellar breeding ground in 30 Doradus, a star-forming complex located in the heart of the Tarantula nebula. View More (2012-04-18)
Hubble's panoramic view of a turbulent star-making region
30 Doradus is the brightest star-forming region in our galactic neighbourhood and home to the most massive stars ever seen. The nebula resides 170 000 light-years away in the Large Magellanic Cloud, a small, satellite galaxy of our Milky Way. No known star-forming region in our galaxy is as large or as prolific as 30 Doradus. View More (2012-04-17)
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)
