The Carl Sagan Institute: Pale Blue Dot and Beyond was founded in 2014 at Cornell University in Ithaca, New York to further the search for habitable planets and moons in and outside the Solar System. It is focused on the characterization of exoplanets and the instruments to search for signs of life in the universe.[1][2] The founder and current director of the institute is astronomer Lisa Kaltenegger.

The institute, inaugurated in 2014 and renamed on 9 May 2015, collaborates with international institutions on fields such as

atmospheric science, geology and biology with the goal of taking an interdisciplinary approach to the search for life elsewhere in the universe and of the origin of life on Earth.[1][3]

Carl Sagan was a faculty member at Cornell University beginning in 1968. He was the David Duncan Professor of Astronomy and Space Sciences and director of the Laboratory for Planetary Studies there until his death in 1996.[1]

Research

The main goal of the Carl Sagan Institute is to model atmospheric

habitable zone around their host stars. The atmospheric characterization of such worlds would allow researchers to potentially detect the first habitable exoplanet.[4] A team member has already produced a "color catalog" that could help scientists look for signs of life on exoplanets.[5]

Bioreflectance spectra catalog

Team scientists used 137 different microorganism species, including

European Extremely Large Telescope.[5]

Ultraviolet radiation on life forms could also induce biofluorescence in visible wavelengths.[8][9] An exoplanet orbiting an M-type star with these life forms would glow when exposed to solar flares, allowing it to be detected by the new generations of space observatories.

Other catalogs and models

Institute scientists have catalogued the spectral emissions and albedo of Solar System objects, including all eight planets, nine moons, and two dwarf planets.[10] They have also modeled Earth's atmosphere throughout geological history.[11] Exoplanets with similar conditions to early Earth are considered candidates for emerging life forms.
