"First results from a major astronomical survey using a cutting-edge technique appear to have confirmed the existence of mysterious dark energy.

"Dark energy makes up some 74% of the Universe and its existence would explain why the Universe appears to be expanding at an accelerating rate.

"The finding was based on studies of more than 200,000 galaxies.

"While dark energy makes up about 74% of the Universe, dark matter - which does not reflect or emit detectable light - accounts for 22%. Ordinary matter - gas, stars, planets and galaxies - makes up just 4% of the cosmos."
