However, Riess, an astronomer at Johns Hopkins University, is still counting on observational astronomy to solve the conundrum in a four phase process.

Riess shared this year's prize with with fellow American Saul Perlmutter and the Australian Brian Schmidt for the discovery, back in 1998, that the expansion of the Universe is accelerating.

Mrs Riess-Passer, who joined Mr Haider as his press officer soon after he took over the party in 1986, is reputed to be tough and have a mind of her own.

He led the Supernova Cosmology Project beginning in 1988, and Prof Schmidt and Prof Riess began work in 1994 on a similar project known as the High-z Supernova Search Team.

Riess and colleagues used the Hubble Space Telescope to measure supernovae that are very far away, showing that dark energy must be responsible for how the universe appears to expand faster and faster.

Even as Adam Riess was regaling the media with an amusing, self-depreciating, anecdote about his early morning wake-up call from Oslo, deep in the bowels of UCL's Department of Physics and Astronomy researchers were putting the finishing touches to a camera that could finally shed some light on the discovery that won him the Nobel Prize for Physics.
