Sometimes it is difficult to take a photograph of an exoplanet because the star illuminating it is too bright. Now there is a new ‘deluminator’ telescope that can block out the extra light.
Over the last 20 years, advances in the field of exoplanet discovery have excited the imaginations of scientists and enthusiasts alike. But we’re in position to know yet whether a planet is habitable.
