Crash Test-Iconic Rings and Flares of Galaxies Created by Violent, Intergalactic Collisions, Research by Pitt and Partners Finds
The bright pinwheels and broad star sweeps iconic of disk galaxies such as the Milky Way might all be the shrapnel from massive, violent collisions with other galaxies and galaxy-size chunks of dark matter, according to a multi-institutional project involving the University of Pittsburgh.   view more (2008-11-24)

Mystery of missing hydrogen
Something vital is missing in the far distant reaches of the Universe: hydrogen - the raw material for stars, planets and possible life.   view more (2008-11-24)

Super-Tough Sunshield to Fly on the James Webb Space Telescope
Imagine sunglasses that can withstand the severe cold and heat of space, a barrage of radiation and high-speed impacts from small space debris. They don't exist, but Northrop Grumman engineers have created a Sunshield for NASA's James Webb Space Telescope that can withstand all of those elements.... view more (2008-11-13)

Giant simulation could solve mystery of 'dark matter'
The search for a mysterious substance which makes up most of the Universe could soon be at an end, according to new research.   view more (2008-11-06)

The NASA/ESA Hubble Space Telescope is back in business
Just a couple of days after the orbiting observatory was brought back online, Hubble aimed its prime working camera, the Wide Field Planetary Camera 2 (WFPC2), at a particularly intriguing target, a pair of gravitationally interacting galaxies called Arp 147.   view more (2008-10-31)

Throwing light on the dark side of the Universe
Although we may believe humans know a lot about the Universe, there are still a lot of phenomena to be explained. A team of cosmologists from the University of the Basque Country are searching for the model that best explains the evolution of the Universe.   view more (2008-10-22)

Serendipitous observations reveal rare event in life of distant quasar
A bit of serendipity has given astronomers a surprise view of a never-before-observed event in the birth of a galaxy.   view more (2008-10-22)

McMaster University unveils world's most advanced microscope
The most advanced and powerful electron microscope on the planet-capable of unprecedented resolution-has been installed in the new Canadian Centre for Electron Microscopy at McMaster University.   view more (2008-10-21)

Cosmic Lens Reveals Distant Galactic Violence
By cleverly unraveling the workings of a natural cosmic lens, astronomers have gained a rare glimpse of the violent assembly of a young galaxy in the early Universe. Their new picture suggests that the galaxy has collided with another, feeding a supermassive black hole and triggering a tremendous... view more (2008-10-21)

Colossal Black Holes Common in the Early Universe
Astronomers think that many - perhaps all - galaxies in the universe contain massive black holes at their centers. New observations with the Submillimeter Array now suggest that such colossal black holes were common even 12 billion years ago, when the universe was only 1.7 billion years old and... view more (2008-10-17)

Listening to dark matter
A team of researchers in Canada have made a bold stride in the struggle to detect dark matter. The PICASSO collaboration has documented the discovery of a significant difference between the acoustic signals induced by neutrons and alpha particles in a detector based on superheated liquids.   view more (2008-10-16)

Stars stop forming when big galaxies collide
Astronomers studying new images of a nearby galaxy cluster have found evidence that high-speed collisions between large elliptical galaxies may prevent new stars from forming, according to a paper to be published in a November 2008 issue of The Astrophysical Journal Letters.   view more (2008-10-08)

More star births than astronomers have calculated
The "birth rate" for stars is certainly not easy to determine. Distances in the universe are far too great for astronomers to be able to count all the newly formed celestial bodies with the aid of a telescope.   view more (2008-10-02)

Young Galaxy's Magnetism Surprises Astronomers
Astronomers have made the first direct measurement of the magnetic field in a young, distant galaxy, and the result is a big surprise.   view more (2008-10-02)

First detection of magnetic field in distant galaxy produces a surprise
Using a powerful radio telescope to peer into the early universe, a team of California astronomers has obtained the first direct measurement of a nascent galaxy's magnetic field as it appeared 6.5 billion years ago.   view more (2008-10-02)

BOSS: the Baryon Oscillation Spectroscopic Survey
The Sloan Digital Sky Survey (SDSS) uses a 2.5-meter telescope with a wider field of view than any other large telescope, located on a mountaintop in New Mexico called Apache Point and devoted solely to mapping the universe.   view more (2008-09-22)

Immigrant Sun: Our star could be far from where it started in Milky Way
A long-standing scientific belief holds that stars tend to hang out in the same general part of a galaxy where they originally formed. Some astrophysicists have recently questioned whether that is true, and now new simulations show that, at least in galaxies similar to our own Milky Way, stars such... view more (2008-09-16)

Yale Astronomer Discovers Upper Mass Limit for Black Holes
here appears to be an upper limit to how big the universe's most massive black holes can get, according to new research led by a Yale University astrophysicist.   view more (2008-09-12)

1843 stellar eruption may be new type of star explosion
Eta Carinae, the galaxy's biggest, brightest and perhaps most studied star after the sun, has been keeping a secret: Its giant outbursts appear to be driven by an entirely new type of stellar explosion that is fainter than a typical supernova and does not destroy the star.   view more (2008-09-11)

Galaxy Zoo -- an Internet superstar
Since Galaxy Zoo's launch in July 2007, some 150,000 members of the public, inspired by the opportunity to be the first to see and classify a galaxy, have helped professional astronomers via this on-line mass-participation project to carry out real scientific research.   view more (2008-09-02)

UCI scientists discover minimum mass for galaxies
By analyzing light from small, faint galaxies that orbit the Milky Way, UC Irvine scientists believe they have discovered the minimum mass for galaxies in the universe - 10 million times the mass of the sun.   view more (2008-08-28)

Hubble sees magnetic monster in erupting galaxy
The Hubble Space Telescope has found the answer to a long-standing puzzle by resolving giant but delicate filaments shaped by a strong magnetic field around the active galaxy NGC 1275. It is the most striking example of the influence of these immense tentacles of extragalactic magnetic fields, say... view more (2008-08-21)

Hubble unveils colourful star birth region on 100 000th orbit milestone
In commemoration of the NASA/ESA Hubble Space Telescope completing its 100 000th orbit around the Earth in its 18th year of exploration and discovery, scientists have aimed Hubble to take a snapshot of a dazzling region of celestial birth and renewal.   view more (2008-08-11)

Study shows clumps and streams of dark matter in inner regions of the Milky Way
Using one of the most powerful supercomputers in the world to simulate the halo of dark matter that envelopes our galaxy, researchers found dense clumps and streams of the mysterious stuff lurking in the inner regions of the halo, in the same neighborhood as our solar system.   view more (2008-08-07)

'Cosmic ghost' discovered by volunteer astronomer
When Yale astrophysicist Kevin Schawinski and his colleagues at Oxford University enlisted public support in cataloguing galaxies, they never envisioned the strange object Hanny van Arkel found in archived images of the night sky.   view more (2008-08-06)
