Eta

Its story

Eta Telescopii is one of the well-identified members of the Beta Pictoris moving group, a stream of very young stars —barely twenty million years old— that share a common origin. A white type A star some 157 light-years away, it is surrounded by a debris disc, planetary-formation leftovers detected in the infrared. It is one of those systems that grant astronomers a rare window onto the earliest chapters in the life of a planetary court.
