Chandra data reveal rapidly whirling black holes
A new study using results from NASA's Chandra X-ray Observatory provides one of the best pieces of evidence yet that many supermassive black holes are spinning extremely rapidly. The whirling of these giant black holes drives powerful jets that pump huge amounts of energy into their environment and affects galaxy growth.   view more (2008-01-11)

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)

Spitzer nets thousands of galaxies in a giant cluster
In just a short amount of time, NASA's Spitzer Space Telescope has bagged more than a thousand previously unknown dwarf galaxies in a giant cluster of galaxies.   view more (2007-05-29)

NASA Telescope Reveals Nearby Galaxy's Invisible Arms
A new image from NASA's Galaxy Evolution Explorer shows that a galaxy once thought to be rather plain and old is actually endowed with a gorgeous set of young spiral arms.   view more (2005-07-25)

Hubble's sweeping view of the Coma Galaxy Cluster
The NASA/ESA Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of Galaxies, one of the densest known galaxy collections in the Universe.   view more (2008-06-10)

Black hole found in enigmatic Omega Centauri
A new discovery has resolved some of the mystery surrounding Omega Centauri, the largest and brightest globular cluster in the sky. Images obtained with the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope and data obtained by the GMOS spectrograph on the Gemini South telescope in Chile show that Omega Centauri appears to... view more...

Super atoms turn the periodic table upside down
Researchers at Delft University of Technology (TU Delft) in The Netherlands have developed a technique for generating atom clusters made from silver and other metals. Surprisingly enough, these so-called super atoms (clusters of 13 silver atoms, for example) behave in the same way as individual atoms and have opened up a whole new branch of... view more...

Bonn astronomers simulate life and death in the universe
Stars always evolve in the universe in large groups, known as clusters. Astronomers distinguish these formations by their age and size. The question of how star clusters are created from interstellar gas clouds and why they then develop in different ways has now been answered by researchers at the Argelander Institute for Astronomy at the... view more...

Hubble sees 'Comet Galaxy' being ripped apart by galaxy cluster
There are many galaxies of different shapes and sizes around us today. Roughly half are gas-poor elliptical-shaped galaxies with little new star formation activity, and half are gas-rich spiral and irregular galaxies with high star formation activity. Observations have shown that gas-poor galaxies are most often found near the centre of crowded... view more... (2007-03-05)

Galaxy Zoo hunters help astronomers discover rare 'Green Pea' galaxies
A team of astronomers has discovered a group of rare galaxies called the "Green Peas" with the help of citizen scientists working through an online project called Galaxy Zoo. The finding could lend unique insights into how galaxies form stars in the early universe.   view more (2009-07-28)

Rogue Black Holes May Roam the Milky Way
It sounds like the plot of a sci-fi movie: rogue black holes roaming our galaxy, threatening to swallow anything that gets too close. In fact, new calculations by Ryan O'Leary and Avi Loeb (Harvard-Smithsonian Center for Astrophysics) suggest that hundreds of massive black holes, left over from the galaxy-building days of the early universe, may... view more...

A new discovery helps us to understand the complex nature of earthquakes
√Ålvaro Corral, a physicist at the Universitat Aut√≤noma de Barcelona, has discovered that the structure of the recurrence time of earthquakes, which is the time interval between successive earthquakes, is similar to the spatial structure of physics systems when they change phase in the "critical points".   view more (2005-07-11)

Cornell-led team detects dust around a primitive star, shedding new light on universe's origins
A Cornell-led team of astronomers has observed dust forming around a dying star in a nearby galaxy, giving a glimpse into the early universe and enlivening a debate about the origins of all cosmic dust.    view more (2009-01-16)

Iowa State astrophysicist helps map the Milky Way's four spiral arms
Iowa State University's Martin Pohl is part of a research team that has developed the first complete map of the Milky Way galaxy's spiral arms.   view more (2009-01-05)

The Milky Way's tiny but tough galactic neighbor
In the new ESO image, Barnard's Galaxy glows beneath a sea of foreground stars in the direction of the constellation of Sagittarius (the Archer).   view more (2009-10-14)

Hubble sees faintest stars in a globular cluster
The NASA/ESA Hubble Space Telescope has uncovered what astronomers are reporting as the dimmest stars ever seen in any globular star cluster.   view more (2006-08-21)

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)

Hubble yields direct proof of stellar sorting in a globular cluster
A seven year study with the NASA/ESA Hubble Space Telescope has provided astronomers with the best observational evidence yet that globular clusters sort out stars according to their mass, governed by a gravitational billiard ball game between stars.   view more (2006-10-25)

XMM-Newton takes astronomers to a black hole's edge
Using new data from ESA's XMM-Newton spaceborne observatory, astronomers have probed closer than ever to a supermassive black hole lying deep at the core of a distant active galaxy.   view more (2009-05-28)

Tracking the spread of cancer cells - Photon02
Not much is known about how clustered cancer cells move, but it is important to understand how individual cancer cells break off from a cluster and spread throughout the human body. A research collaboration between the University of Wales College of Medicine and Kingston University * has lead to the development of a computational imaging technique... view more... (2002-08-28)
