The vast majority of planets near foreign stars are discovered by astronomers with the help of sophisticated methods. The exoplanet does not appear in the image, but reveals itself indirectly in the spectrum. A team of scientists from the Max Planck Institutes for Astronomy and Extraterrestrial Physics has now succeeded in obtaining the first direct confirmation of a previously discovered exoplanet using the method of radial velocity measurement. Using the the GRAVITY instrument at the VLT telescopes in Chile, the astronomers observed the faint glint of the planet Beta Pictoris c, some 63 light-years away from Earth, next to the bright rays of its mother star. The researchers can now derive both the brightness and the dynamic mass of an exoplanet from these observations and thus better narrow down the formation models of these objects.
