A recent discovery announced at the Goldschmidt Conference in Boston, Massachusetts, United States, has found that these ‘water worlds’ are more common than previously thought. This discovery comes courtesy of data collected by two very diligent missions that have studied the cosmos for years now – the European Space Agency’s Gaia and NASA’s Kepler. Of the 4,000 confirmed or candidate exoplanets, 35 per cent were found to be water worlds.The first discovery of exoplanets was announced in 1992 with the planets PSR B1257+12c and 12d.They were found to be orbiting a pulsar 2,300 light years away in the constellation of Virgo. A third planet, PSR B1257+12b, was found orbiting the same pulsar in 1994. Over two decades later the search for exoplanets continues, with new discoveries
