Hubble expert gives city lecture

HUBBLE SPACE TELESCOPE

Named after the great US astronomer Edwin Hubble
Launched in 1990 into a 600km-high circular orbit
Equipped with a 2.4m primary mirror and five instruments
Length: 15.9m; diameter: 4.2m; Mass: 11,110kg

A leading light in the European Space Agency is to tell a Belfast audience how the Hubble telescope has "built a bridge between science and art".

Lars Lindberg Christensen is in the city for a talk explaining how it has been "one of the most successful scientific projects of all time".

The lecture is a community outreach initiative between Queen's University and the Irish Astronomical Association.

Hubble is the world's flagship space-borne observatory.

Launched in 1990, the telescope delivers unprecedented pictures of the Universe and gathers information that has led to new understanding of how the cosmos formed and what it contains.

In January, the US space agency (Nasa) announced details of a challenging mission to service Hubble.

Without an upgrade, the multi-billion-dollar orbiting observatory is likely to fail in 2010 or 2011.

The planned fix will provide a massive boost to Hubble's capabilities, giving it greater sensitivity and a larger field of view.

Mr Christensen's lecture on Hubble is one of several public events to be held at the Royal Astronomical Society's National Astronomy Meeting 2008 taking place at Queen's this week.

It will feature a presentation of the latest scientific study of Hubble galaxy images by astronomers at Queen's.

Mr Christensen said: "Hubble's exquisite image quality has enabled astronomers to gain entirely new insights into the workings of a huge range of different astronomical objects and provided the visual overview of underlying astrophysical processes taking place in planets, stars and galaxies."

Lars Lindberg Christensen is based at Hubble European Space Agency (Esa) Information Centre in Munich, Germany. Esa is a 15% partner on the telescope with Nasa.

The lecture takes place in the Larmor lecture theatre, Physics and Astronomy Building, at Queen's at 1930 GMT on Wednesday. Admission is free.
