The discovery of a previously unresolved population of galaxies in the GOODS fields and the first measurements of properties of galaxies in the almost unexplored far-infrared domain are among the first exciting scientific results achieved by Herschel's PACS and SPIRE instruments. These findings confirm the extraordinary capabilities of ESA's new infrared space observatory to investigate the formation and evolution of galaxies.

Herschel's HIFI instrument was especially designed to follow the water trail in the Universe over a wide range of scales, from the Solar System out to extragalactic sources. Early results, presented this week at the Herschel First Results Symposium, demonstrate how HIFI uses water to probe the physical and chemical conditions in different regions of the cosmos.

The HIFI instrument onboard Herschel has been successfully switched on, after being inactive due to an unexpected anomaly in the electronic system. This achievement brings Herschel back to its full observing capacity.

It must be one of the oldest questions. When you gaze at the sky, you marvel at its immensity. Have you ever, at some stage of your life, looked up into the night sky and wondered just how many stars there are in space? The question has fascinated scientists as well as philosophers, musicians, and dreamers through the ages.

Astrium will build the 3.5-metre mirror for ESA's Herschel Space Observatory Giant telescopes with primary mirrors of 8 metres in diameter are now common on the ground, but it will take a while before they can jump into space. The first 'space giant' to come will be on ESA's Herschel Space Observatory, to be launched in 2007.

On 2 April 2001 the Director of Science issued an Announcement of Opportunity for a Herschel Optical Systems Scientist. In the interest of appointing the Optical Systems Scientist on a short timescale, the deadline for submitting a Letter of Intent is 12 April, and the Proposals are due by 25 April. Note, however, that a proposal may be submitted even if a Letter of Intent has not been sent in time for the deadline.

On 14 March, in Paris, ESA's Industrial Policy Committee approved the awarding of the main contract for the manufacture of the Herschel and Planck scientificsatellites. This contract, the largest so far for a space science project undertaken by ESA, has been awarded to a European industrial consortium led by Alcatel Space Industries of France, with Astrium GmbH of Germany and Alenia Spazio of Italy also as main contractors.

In science, new answers often trigger new questions. And in astronomy, new questions often mean new instruments. The ESA 'Herschel Space Observatory', formerly called 'Far Infrared and Submillimetre Telescope' (FIRST), is the instrument that inherits many of the questions triggered by its predecessor, ESA's Infrared Space Observatory (ISO). 200 astronomers from all over the world met last week in Toledo, Spain, to discuss how to insert these new questions in Herschel's 'scientific agenda'. Thus, Herschel will study the origin of stars and galaxies -its main goals-, but it will also keep on searching for water in space -as ISO did-, and will help us to understand the formation of our own Solar System through detailed observations of comets and of the poorly known 'transneptunian objects'.

There are still quite a lot of unsolved mysteries in our neighbourhood, the Solar System. Astronomers knowvery little, for instance, about the so-called 'transneptunian objects': a ring of asteroid-type bodies located beyond planet Neptune. Dutch astronomer Gerald Kuiper predicted the existence of this 'belt' fifty years ago - it is therefore named the 'Kuiper belt'-, but the first detection of one of its constituent bodies only happened in 1992. Further surveys have provided an estimate of how many objects are actually there: possibly 10.000 bodies with a diameter larger than 300 kilometres, and maybe three million larger than 30 kilometres in diameter. Only 300 of them have been observed so far. The list of pending questions about them is very long: what's their precise origin and composition? Which of the comets that periodically visit the Earth are 'Kuiper objects'? ESA's next infrared space telescope, the Herschel Space Observatory - formerly called 'FIRST' - will help to provide the answers, astronomers gathered in Toledo (Spain) said yesterday.
