Astronomers discover dozens of mini-galaxies
A new survey made with the Anglo-Australian Telescope (AAT) has revealed dozens of previously unsuspected miniature galaxies in the nearby Fornax galaxy cluster. They belong to a class of galaxies dubbed "ultra-compact dwarfs" (UCDs), which was unknown before the same team of astronomers... view more (2004-03-25)

Cosmic thermostats provide clue to 30 year old astronomy puzzle (Embargoed until 1900 hrs London time Wednesday 17 July 2002)
A cosmic phenomenon involving pockets of hot gas in space which appear not to cool down has been puzzling astronomers for three decades. Now new research by Dr Christian Kaiser at the University of Southampton and Professor Marcus Brüggen of the International University Bremen, Germany, shows... view more (2002-07-16)

COROT finds exoplanet orbiting Sun-like star
A team of European scientists working with COROT have discovered an exoplanet orbiting a star slightly more massive than the Sun. After just 555 days in orbit, the mission has now observed more than 50 000 stars and is adding significantly to our knowledge of the fundamental workings of stars.   view more (2008-07-28)

The colourful demise of a Sun-like star
A brand new image taken with Hubble's Wide Field Planetary Camera 2 shows the planetary nebula NGC 2440 - the chaotic structure of the demise of a star.   view more (2007-02-15)

The case of the neutron star with a wayward wake
A long observation with NASA's Chandra X-ray Observatory revealed important new details of a neutron star that is spewing out a wake of high-energy particles as it races through space.   view more (2006-06-02)

First Cluster apogee burn completed
The long, complex process required to elongate the orbits of the first twoCluster spacecraft has begun. The Cluster mission control centre at the European Space Operations Centre(ESOC) in Darmstadt, Germany, has confirmed that the apogee raising manoeuvre #1was completed successfully early this... view more (2000-07-17)

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... view more (2008-04-02)

Hubble images some of galaxy's dimmest stars
Using the Hubble Space Telescope, astronomers have imaged some of the galaxy's oldest and dimmest stars, offering a rare experimental glimpse of two mysterious star types - tiny, slow burners less than one-tenth the size of our sun and once giant stars that still glow more than 10 billion years... view more (2006-08-21)

Visit by Director of European Space Agency'­s Scientific Programme
Professor R M Bonnet, Scientific Programme Director at the European Space Agency (ESA), visited Rutherford Appleton Laboratory (RAL) today, Tuesday 30 January, to see a demonstration of the operations and data handling facilities for the Cluster spacecraft, which are due to be launched in the... view more (1996-02-01)

NASA's Swift satellite images a galaxy ablaze with starbirth
Combining 39 individual frames taken over 11 hours of exposure time, NASA astronomers have created this ultraviolet mosaic of the nearby "Triangulum Galaxy."   view more (2008-02-26)

After the World Cup... the dancing continues in space
The Brazilian World Cup celebrations may have started to die down, but in space the never-ending football match between the Sun and Earth continues. And watching this match closely are Salsa, Samba, Rumba and Tango, the four satellites that make up the Cluster mission. They are performing their... view more (2002-07-08)

SMART-1 'star tracker' peeks at the approaching lunar surface
While ESA's SMART-1 mission is running on its last orbits around the Moon before its planned lunar impact on 3 September 2006, the spacecraft 'star tracker' - or attitude camera-is taking exciting pictures of the ever approaching surface.   view more (2006-08-30)

Glasgow astronomers explain hot star disks
Astronomers have been puzzled for decades as to how the rings of hot gas surrounding certain types of star are formed. Now a team of scientists from the Universities of Glasgow and Wisconsin believe they have found the answer. The team studied a type of young, hot star, known as a "Be star", that... view more (2002-11-01)

Planets forming in Pleiades star cluster, astronomers report
Rocky terrestrial planets, perhaps like Earth, Mars or Venus, appear to be forming or to have recently formed around a star in the Pleiades ("seven sisters") star cluster, the result of "monster collisions" of planets or planetary embryos.   view more (2007-11-16)

Cluster makes a shocking discovery
ESA's Cluster was in the right place and time to make a shocking discovery. The four spacecraft encountered a shock wave that kept breaking and reforming - predicted only in theory.   view more (2007-05-15)

Migraine treatment also appears effective for cluster headaches
Zolmitriptan nasal spray, used to treat migraine headaches, also may be safe and effective in treating painful cluster headaches.   view more (2006-09-12)

Chandra discovers cosmic cannonball
One of the fastest moving stars ever seen has been discovered with NASA's Chandra X-ray Observatory. This cosmic cannonball is challenging theories to explain its blistering speed.   view more (2007-11-29)

Scientists Find Giant Ring Encircling Exotic Dead Star
One of the most powerful eruptions in the universe might have spun an infrared ring around a rare and exotic star known as a magnetar, a highly magnetized neutron star and the remnant of a brilliant supernova explosion signaling the death throes of a massive star.   view more (2008-05-29)

VLT Observations Address the Age of the Universe
The stream of important scientific results from ESOs Very Large Telescope (VLT) at Paranal (Chile) is increasing. Astronomers have had access to the first of the four 8.2-m telescopes since April 1999 and research articles based on observations with this new powerful facility are beginning to... view more (1999-12-17)

UI researchers discover star orbiting a 'medium-sized' black hole
University of Iowa researchers have found a star orbiting a "medium-sized" black hole - about 1,000 times more massive than the sun - in the nearby starburst galaxy M82, a development that may help explain how medium-sized black holes form and evolve.   view more (2006-01-06)

UK Astronomers Survey Galactic Graveyard
An unprecedented source of planetary nebulae, the disk-like relics of elderly, dying stars, has been discovered in the southern part of our Milky Way galaxy. With about 1000 planetary nebulae found so far and many more still to be discovered, the number of aged stars in their death throes revealed... view more (2002-04-07)

How do massive stars form?
Massive stars play a key role in the chemical and dynamical evolution of galaxies. The way massive stars form is still much debated among the astronomers' community: it is currently one of the hottest astrophysical topics.   view more (2005-11-09)

Killer electrons in space are now less mysterious
A rare, timely conjunction of ground-based instrumentation and a dozen satellites has helped scientists better understand how electrons in space can turn into 'killers'. ESA's Cluster constellation has contributed crucially to the finding.   view more (2007-07-27)

Neutron stars can be more massive, while black holes are more rare, Arecibo Observatory finds
Neutron stars and black holes aren't all they've been thought to be. In fact, neutron stars can be considerably more massive than previously believed, and it is more difficult to form black holes, according to new research developed by using the Arecibo Observatory in Arecibo, Puerto Rico.   view more (2008-01-15)
