Supernova Imposter Goes Supernova
In a galaxy far, far away, a massive star suffered a nasty double whammy. On Oct. 20, 2004, Japanese amateur astronomer Koichi Itagaki saw the star let loose an outburst so bright that it was initially mistaken for a supernova. The star survived, but for only two years. On Oct. 11, 2006,... view more (2007-04-05)

Set your own course for the stars
To get around, satellites sailing through space use the same tools that ancient mariners used to navigate the inhospitable oceans - the stars. However, soon, instead of sending back details of their position to experts here on Earth, spacecraft will be able to calculate and adjust their course all... view more (2002-11-12)

Astronomers discover record 5th planet around nearby star 55 Cancri
A team of American astronomers announced today (Tuesday, Nov. 6) the discovery of a record-breaking fifth planet around the nearby star 55 Cancri, making it the only star aside from the sun known to have five planets.   view more (2007-11-07)

Life patterns
A new use of old technology could lead to handheld scanning diagnostic devices (as seen in Star Trek!) one day becoming a reality.   view more (2002-10-07)

Superbubble of supernova remnants caught in act of forming
A superbubble in space, caught in the act of forming, can help scientists better understand the life and death of massive stars, say researchers at the University of Illinois at Urbana-Champaign.   view more (2007-01-10)

Magnetism shapes beauty in the heavens
Using a technique based on the work of the 1902 Nobel Prizewinner, Pieter Zeeman, an international team of astronomers have, for the first time, provided conclusive proof that the magnetic field close to a number of aging stars is 10 to 100 times stronger than that of our own Sun. These... view more (2002-11-01)

Interstellar searchlights catch star factories in their beams
Jets of particles from newly formed stars are acting like searchlights, piercing the gloom of dark interstellar clouds to pick out clumps of gas that may become future stars. Astronomers at University College London (UCL) and the University of Barcelona have discovered how these interstellar beams... view more (2002-04-04)

Hubble panoramic view of Orion Nebula reveals thousands of stars
In one of the most detailed astronomical images ever produced, the NASA/ESA Hubble Space Telescope is offering an unprecedented look at the Orion Nebula.   view more (2006-01-12)

Powerful explosions suggest neutron star missing link
Observations from NASA's Rossi X-ray Timing Explorer (RXTE) have revealed that the youngest known pulsing neutron star has thrown a temper tantrum.   view more (2008-02-22)

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)

Cannibalistic Stars hold clue to Big Bang
A team of UK astronomers announced this month the discovery of cannibalistic stars that explain one of the mysteries surrounding the Big Bang. The stars are almost as old as the Universe and they reveal what space was like in the very beginning. The team from the Open University found that a group... view more (2002-05-10)

Cluster - new insights into the electric circuits of polar lights
Giant electrical circuits power the magical open-air light show of the auroras, forming arcs in high-latitude regions like Scandinavia. New results obtained thanks to ESA's Cluster satellites provide a new insight into the source of the difference between the two types of electrical circuits... view more (2007-02-12)

Supernova leaves behind mysterious object
Thanks to data from ESA's XMM-Newton satellite, a team of scientists taking a closer look at an object discovered over 25 years ago have found that it is like none other known in our galaxy.   view more (2006-07-10)

Search for the water of life -- UCL astronomers find water on extra-solar planet
Researchers at UCL (University College London) are part of an international team which has discovered water on an extra-solar planet for the first time.   view more (2007-07-12)

Into the Epoch of Galaxy Formation
Current theories hypothesize that more than 80% of all stars ever formed were assembled in galaxies during the latter half of the elapsed lifetime of the Universe, i.e., during the past 7-8 billion years.   view more (2000-02-17)

`Quiet` star wasn`t quiet after all, say astronomers
For more than two years the star was `quiet`. Or so astronomers thought. But the X-ray pulsar EXO 2030+375 was abuzz with activity. Scientists simply lacked the ability to `hear` it over the hum of a nearby black hole. Now a study by scientists at the University of Southampton, the National Space... view more (2002-07-10)

Astronomers Unravel Mystery of Gamma Ray Bursts
The cause of gamma ray bursts, the most violent and explosive events in the Universe, has remained a mystery since they were first discovered in 1967. Now a team of scientists, led by astronomers from the University of Leicester, believes they have found an answer to the puzzle. Their research... view more (2002-04-04)

Red dust in planet-forming disk may harbor precursors to life
Astronomers at the Carnegie Institution have found the first indications of highly complex organic molecules in the disk of red dust surrounding a distant star.   view more (2008-01-04)

Two new dusty planetary disks may be astrophysical mirrors of our Kuiper Belt
A survey by NASA's Hubble Space Telescope of 22 nearby stars has turned up two with bright debris disks that appear to be the equivalent of our own solar system's Kuiper Belt, a ring of icy rocks outside the orbit of Neptune and the source of short-period comets.   view more (2006-01-20)

Astronomers use Hubble to 'weigh' Dog Star's companion
For astronomers, it's always been a source of frustration that the nearest white-dwarf star is buried in the glow of the brightest star in the nighttime sky. This burned-out stellar remnant is a faint companion of the brilliant blue-white Dog Star, Sirius, located in the winter constellation Canis... view more (2005-12-13)

The fine line between stability and instability -- when do gas giants reach the point of no return?
Planetary scientists at UCL have identified the point at which a star causes the atmosphere of an orbiting gas giant to become critically unstable, as reported in this week's Nature (December 6).   view more (2007-12-06)

UK science minister inaugurates Star Tiger project
An innovative project known as Star Tiger was officially inaugurated at Rutherford Appleton Laboratory (RAL) in Oxfordshire this week by Lord Sainsbury, Science and Innovation Minister for the UK. The Star Tiger concept puts together a highly motivated team with solid scientific background and... view more (2002-07-02)

Interstellar Weather Report: Day and Night Temps Measured on an Extrasolar Planet
For the first time, astronomers have measured the day and night temperatures of a planet outside our solar system. The team, which includes Sara Seager of Carnegie's Department of Terrestrial Magnetism, revealed that a giant Jupiter-like gas planet orbiting very close to its star is blisteringly... view more (2006-10-13)

Flares illuminate the secret life of a quiescent black hole
Astronomers probing the intimate details of apparently quiescent stellar black holes have discovered that in reality they are dynamic, lively places, subject to flares that briefly illuminate the whole of the gas disc around the black hole. Their observations are helping to build up a picture of... view more (2002-04-04)

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)
