Breakthrough Listen: Exotic Target Catalog

Overview - The Breakthrough Listen Exotic Target Catalog

Breakthrough Listen to date has largely focused on the search for "life as we know it" - including Earthlike planets around Sunlike stars such as Kepler 160. But what if extraterrestrial intelligences are not like us, but are found in the frigid reaches of the outer Solar System, the extreme gravity of neutron stars, the brilliant cores of active galaxies, or the hearts of the richest galaxy clusters? Now we're announcing an expanded approach, targeting "one of everything" in the Universe. The new Exotica Catalog includes over 700 distinct objects. It has an example of each type in our Prototype sample, extreme objects with record-breaking properties in our Superlative sample, and lingering mysteries in our Anomaly sample. A small Control sample rounds out the list with sky locations we do not expect to be special as a comparison. With the Exotica catalog, we aim to answer many questions. Have we been looking in the wrong places? Might a few of the objects we think are natural actually be artificial? Could some natural phenomenon or problem with our instruments fool us into thinking we are looking at a signal from an intelligence? What can we learn by using the unique Breakthrough Listen backend to observe the natural world?
