Kalas and a multi-institutional team using GPI first targeted the star in search of other planets in May 2015 and discovered that it was surrounded by a ring
of dusty material very close to the size of our own solar system's Kuiper Belt.
When comets approach the Sun, these ices heat up, eventually turning to gases that jet out into space together
with dusty material to form a head or coma around the cometary nucleus.
According to astronomers,
dusty materials circling around a young star clump together to form asteroids that smash into each other.
The New Worlds Technology Development Program, which lays the scientific groundwork for a future mission to study nearby Earth - like planets, and the Cerro Chajnantor Atacama Telescope, which would provide short - wavelength radio surveys to
study dusty material associated with galaxies and stars, are ranked the highest priority for midsize space - and ground - based programs, respectively.
He immediately reanalyzed existing images of the star taken earlier by the Hubble Space Telescope and discovered that the ring of
dusty material extended much farther away and was extremely lopsided.
The team believes this contradiction could be explained if the planet was embedded in a large cloud
of dusty material, which scatters the light of the star.
His model predicts that the collision between the jet of gas and
the dusty material and gases inside a galaxy would produce characteristic emissions of light.
