EU researchers have pioneered new calibration strategies for detecting “habitable” planets outside our solar system – with impressive results already.
The existence of extra-terrestrial life presupposes the existence of habitable planets – like Earth – outside our solar system. What makes our own planet so special is the fact that it has a solid outer crust and is situated at a distance from the sun where liquid water can exist. Only a few other planets have ever been discovered which satisfy these ‘habitability’ criteria.
Through pioneering new calibration strategies for detecting the tiniest variations in light waves from stars, the EU-funded WAVELENGTH STANDARDS project aims to help astronomers find new ‘habitable’ planets, and perhaps one day help us answer the question of whether we are truly alone in the universe.
