25 March 2002: The disturbed spiral galaxy NGC 7673 is ablaze with the light from millions of new stars. Each of its infant giant blue star clusters shines 100 times as brightly in the ultraviolet as similar immense star clusters in our own Galaxy. Scientists studying this object have two pressing questions: 'What has triggered this enormous burst of star formation and how will this galaxy evolve in the future?'

European Faint Object Camera on Hubble sets world record - celebrating the successes of ESA's sharp-sighted camera
7 March 2002: When the new Advanced Camera for Surveys was installed on the ESA/NASA Hubble Space Telescope Thursday noon (European time) it replaced the European Space Agency's Faint Object Camera (FOC). FOC has spent a record-breaking 4340 days (nearly 12 years) in space. Throughout its 12-year lifetime FOC has celebrated a number of successes. Most notable are the first direct image of the atmosphere of a star, the first sighting of surface details on the planet Pluto, and the first image of an 'exposed' black hole.

5 March 2002: The power for Hubble's scientific discoveries comes from solar cells. Designing and constructing Hubble's first two sets of solar cell arrays constituted a huge technological achievement for the European Space Agency and European industry. After an in-orbit life of more than 8 years, this example of pioneering space technology was this morning (European time) replaced by new, more powerful arrays.

15 February 2002: After nearly 12 years of incredible scientific discoveries, the ESA/NASA Hubble Space Telescope orbiting Earth is about to have another service visit. The purpose is to upgrade Hubble's systems and to install newer and more powerful instruments that will astoundingly increase Hubble's discovery capabilities and extend the longevity of the observatory.

13 February 2002: Combining Hubble Space Telescope images with radio observations has revealed a highly unusual system consisting of a fast spinning pulsar and a bloated red companion star. The existence of the system is something of a mystery - the best explanation so far is that we have our first view of a millisecond pulsar just after it has been 'spun up' by its red companion star.

Students follow in the footsteps of scientists - ESA/ESO astronomy exercises provide a taste of real astronomy
14 December 2001: The ESA/ESO Astronomy Exercise Series', published today, allows students to gain exciting hands-on experience in astronomy by making realistic calculations with data obtained by the world's best telescopes. The students measure and calculate the distances and ages of astronomical objects, among the most basic problems in modern astrophysics, using observations made by the NASA/ESA Hubble Space Telescope and ESO's Very Large Telescope.

5 December 2001: Astronomers have observed a Dark Matter object directly for the first time. Images and spectra of a MACHO microlens - a nearby dwarf star that gravitationally focuses light from a star in another galaxy - were taken by the NASA/ESA Hubble Space Telescope and the European Southern Observatory's Very Large Telescope. The result is a strong confirmation of the theory that a large fraction of Dark Matter exists as small, faint stars in galaxies such as our Milky Way.

5 December 2001: A new European initiative called the Astrophysical Virtual Observatory (AVO) is being launched to provide astronomers with a breathtaking potential for new discoveries. It will enable them to seamlessly combine the data from both ground- and space-based telescopes which are making observations of the Universe across the whole range of wavelengths - from high-energy gamma rays through the ultraviolet and visible to the infrared and radio.

5 October 2001: A very small, faint galaxy - possibly one of the long sought `building blocks' of present-day galaxies - has been discovered by a collaboration between the Hubble Space Telescope and the Keck Telescopes at a tremendous distance of 13.4 billion light-years (based on the estimate of 14 billion years as the age of the Universe). The discovery was made possible by examining small areas of sky viewed through massive intervening clusters of galaxies. These act as a powerful gravitational lens, magnifying distant objects and allowing scientists to probe how galaxies assemble at very early times. This has profound implications for our understanding of how and when the first stars and galaxies formed in the Universe.

11 September 2001: The dedicated team effort to understand and correct systematic effects in observations from Hubble's Faint Object Spectrograph has now been concluded. In future astronomers who use the observations from this instrument will be able to measure the exact velocity of interstellar clouds, as well as the motions of individual parts of nebulae and galaxies. This will for instance lead to better determinations of black hole masses.

Virtual Telescope Observes Record-Breaking Asteroid - New data show that '2001 KX76' is larger than Ceres
23 August 2001: Ceres, the first asteroid (minor planet) to be discovered in the Solar System, has held the record as the largest known object of its kind for two centuries. However, recent observations at the European Southern Observatory with the world's first operational virtual telescope, Astrovirtel, have determined that the newly discovered distant asteroid '2001 KX76' is significantly larger, with a diameter of 1200 km, possibly even 1400 km.

24 July 2001: Hubble observations have revealed huge waves sculpted in the Red Spider Nebula. This warm and windy planetary nebula harbours one of the hottest stars in the Universe and its powerful stellar winds generate waves 100 billion kilometres high - intimidating for even the bravest space surfers.

10 July 2001: The Double Cluster NGC 1850 found in one of our neighbouring galaxies, the Large Magellanic Cloud, is an eye-catching object. It is a young globular-like star cluster - a type of object unknown in our own Milky Way galaxy. Moreover, NGC 1850 is surrounded by a pattern of filamentary nebulosity thought to have been created during supernova blasts.

28 March 2001: Extremely intense radiation from newly born, ultra-bright stars has blown a glowing spherical bubble in the nebula N83B. A new NASA/ESA Hubble Space Telescope image has helped to decipher the complex interplay of gas and radiation in a star-forming region of a nearby galaxy. The image graphically illustrates just how these massive stars sculpt their environment by generating powerful winds that alter the shape of the parent gaseous nebula. These processes are also seen in our own Milky Way in regions like the Orion Nebula.
