The SPHERE instrument is installed on one of the four giant telescopes of the Very Large Telescope (VLT) in Chile. It is one of the most complex ground-based instruments for astronomical observation ever built. Its purpose: to directly image extrasolar planets.

This image, captured in the near-infrared region, shows the exoplanet orbiting around star HIP65426 in the Scorpius-Centaurus association. Light from the central star is blocked by a coronagraph. The discovered exoplanet is 6 to 12 times larger than Jupiter in mass and is located at a distance three times further than the distance between Neptune and the Sun.

Light spectrum of exoplanet HIP65426b in the near-infrared region showing the presence of water in its atmosphere. This spectrum can be seen as the 'fingerprint' of the exoplanet.
