Irish people can be proud of the success of the James Webb Space Telescope (JWST) as Irish scientist Professor Tom Ray and Dr Patrick Kavanagh helped to build one of the cameras that it uses.
Dr Kavanagh will give a public lecture about it on July 18 (www.astronomy.ie) and explain just how important this particular camera is, as it will show us the very early universe just after the Big Bang. That is invisible to even the Hubble Space Telescope, which JWST supercedes.
