Cat's Eye Nebula in Stunning Detail [heic0414]
A new study of a large number of planetary nebulae has revealed that rings, such as those seen here around the Cat's Eye Nebula, are much more common than thought so far and have been found in at least one third of all planetary nebulae.

Hubble peers inside a celestial geode [heic0413]
The strong stellar wind and intense ultraviolet radiation of a young hot star is blowing a bubble into the surrounding gas. The object, known as N44F, lies in our neighbouring dwarf galaxy the Large Magellanic Cloud.

ESA's Integral detects closest cosmic gamma-ray burst
gamma-ray burst detected by ESA's Integral gamma-ray observatory on 3 December 2003 has been thoroughly studied for months by an armada of space and ground-based observatories. Astronomers have now concluded that this event, called GRB 031203, is the closest cosmic gamma-ray burst on record, but also the faintest. This also suggests that an entire population of sub-energetic gamma-ray bursts has so far gone unnoticed.

News Release: Hubble assists Rosetta comet mission [heic0310]
Results from the HST played a major role in preparing ESA’s ambitious Rosetta mission for its new target, comet 67P/ Churyumov-Gerasimenko. Hubble measured precisely the size, shape and rotational period of the comet.

PR 46-2003: Golden legacy for Infrared Space Observatory
Scientists are celebrating the thousandth scientific publication from ESA's Infrared Space Observatory (ISO). ISO is fast becoming one of the world's most productive space missions, even though its operational life ended in 1998.

A gamma-ray burst bonanza
ESA's Integral satellite is detecting gamma-ray bursts at a rate of nearly one per day, establishing itself as a key player in the hunt for these enigmatic explosions.

Is it a star? Is it a planet? ISO may have discovered the true nature of brown dwarfs
Nature enjoys teasing us. Stars are stars and planets are planets, you may think. In reality it is not as clear-cut as that with the discovery of more and more objects that are neither star nor planet. An Italian team, using observations by ESA's Infrared Space Observatory, ISO, has obtained the first detailed evidence that these ambiguous star-planet 'missing links' form in the same manner as stars, tipping the balance in favour of a stellar origin.

A game reserve for brown-dwarf hunters - ISO finds 30 'failed stars' in nearby stellar nursery
The impressive rho Ophiuchi cloud is one of the heavenly meeting points for astronomers in search of young stars. Located 540 light-years away in the constellation of Ophiucus, in the celestial equator, this dusty region is the nest of more than one hundred newborn stars. But ESA's Infrared Space Observatory, ISO, has also found a surprise hidden in the dust: 30 brown dwarfs, elusive and ambiguous objects considered to be 'failed stars' because they have too little mass to shine as stars. Relatively few of these brown dwarfs have been identified so far, so finding one is like winning a trophy. With this discovery ISO has turned the rho Ophiuchi region into a favourite game reserve for brown-dwarf hunters.
