The new observations required the latest, most sophisticated versions of two technologies. Large ground-based telescopes had to be fitted with so-called adaptive optics that compensate for the blurring effects of the atmosphere. These observatories and the orbiting Hubble Space Telescope also needed equipment to block most of the light from a central star.
With such modified scopes, astronomers led by Christian Marois of the National Research Council's Herzberg Institute of Astrophysics in Victoria, Canada, spotted three objects near a star 128 light-years away designated HR 8799. Another team, led by Paul Kalas of the University of California, Berkeley, found an additional exoplanet near the star Fomalhaut, just 25 light-years away and one of the brightest stars in the sky. All of the objects appeared to orbit their stars, fulfilling one requirement for a bona fide exoplanet detection.
This is all well and good, but have they found ET's home yet?
