Hubble uncovers the first high-resolution details in a gamma-ray burst host galaxy [heic0003]
A group of European astronomers have obtained the first detailed images of a galaxy in which a gamma-ray burst has occurred. The image was taken with one of the NASA/ESA Hubble Space Telescope's high-resolution cameras and reveals a barred spiral galaxy with numerous star-forming regions. The gamma-ray burst has been located in one such actively star-forming region. This is a very important step forward in our understanding of gamma-ray bursts and their immediate surroundings and offers possible clues to their progenitors.

SOHO and Cluster Exhibition opens in Norway
An exhibition on 'The Sun - our star' opened at the Norwegian Technical Museum in Oslo on 22 June. The exhibits include 1:4 scale models of the SOHO and Cluster II satellites as well as several metres of panels with information on the science from these ESA missions. The ESA SOHO CD-Rom can be viewed interactively by the visitors and SOHO real-time pictures are displayed continuously.

Water discovery gives new impetus to Mars Express
"The latest evidence that liquid water has flowed on Mars very recently, makes Mars Express even more relevant," says Agustin Chicarro, Mars Express Project Scientist. "Water may have flowed tens of thousands or a million years ago - that's still recent in geological terms. Or it may even be flowing now. Either way, this is very important."

INFO 08-2000: ISO Shows What's in the Centre of our Galaxy
The Milky Way's centre is the busy core of a metropolis, crowded with huge populations of stars frantically dancing to the rhythm of gravitation. These stars are precious for astronomers: they hold many clues to unveil the past and future history of our galaxy. But the galactic centre has remained a fairly unexplored place so far, due to the thick dust covering it.

Danish Space Research Institute to build the mirrors of ESA's Planck telescope
The Danish Space Research Institute (DSRI) will develop the main elements of the telescope of ESA's Planck satellite, according to a document signed yesterday by ESA and the DSRI at ESA headquarters in Paris. Planck, due to be launched in 2007, will study the origin and evolution of the Universe by observing the Cosmic Microwave Background radiation, the first light that filled the Universe after the Big Bang.

XMM-Newton reveals a cluster of galaxies
Serendipity, or chance discovery, plays a big role in astronomy. Observing one celestial target astronomers often find, in a corner of their telescope's field of view, another interesting and perhaps unknown object. XMM-Newton has made one such discovery.

ISO measures temperature variations of the surface of Pluto
A team from the Observatoire de Paris using ESA's infrared space telescope ISO has measured variations in the thermal flux of the Pluto-Charon system, which prove that the temperature of Pluto's surface is not uniform. The coldestregions have a temperature of about -235 degrees Centigrade, while the warmest may reach -210 degrees. The measurements provide indications about its physical nature.

Intensive observing campaign in Spain to follow up ISO discoveries
The European Space Agency's ISO telescope was the first space observatoryrevealing the infrared 'face' of the Universe with high sensitivity, andby so doing pictured thousands of objects whose true nature is stillunknown. This month a network of European astronomers will try to learnmore about these new ISO sources, by observing many of them with about adozen ground-based telescopes, mainly at the observatories in theCanary Islands (Spain)."ISO has worked as a 'scoop' finder, and nowthere's a whole set of telescopes following up the news", says MartinKessler, ISO Project Scientist. The new ISO sources will soon also be observed with ESA's recently launched X-ray telescope, XMM-Newton.
