Exoplanet Transits as the Foundation of an Interstellar Communications Network
Two fundamental problems for extraterrestrial intelligences (ETIs) attempting to establish interstellar communication are timing and energy consumption. Humanity’s study of exoplanets via their transit across the host star highlights a […]
Thermal and energetic processing of astrophysical ice analogues rich in SO2
Sulfur is an abundant element in the cosmos and it is thus an important contributor to astrochemistry in the interstellar medium and in the Solar System. Astronomical observations of the […]
Searching for Exoplanets Using Artificial Intelligence
In the last decade, over a million stars were monitored to detect transiting planets. Manual interpretation of potential exoplanet candidates is labor intensive and subject to human error, the results […]
A Search for Laser Emission with Megawatt Thresholds from 5600 FGKM Stars
We searched high resolution spectra of 5600 nearby stars for emission lines that are both inconsistent with a natural origin and unresolved spatially, as would be expected from extraterrestrial optical […]
Venus: Key to Understanding the Evolution of Terrestrial Planets
Why are the terrestrial planets so different? Venus should be the most Earth-like of all our planetary neighbours. Its size, bulk composition and distance from the Sun are very similar […]
SETIBURST: A Robotic, Commensal, Realtime Multi-Science Backend for the Arecibo Telescope
Radio astronomy has traditionally depended on observatories allocating time to observers for exclusive use of their telescopes. The disadvantage of this scheme is that the data thus collected is rarely […]
Sub-milli-Kelvin Instruments – Radial Velocity Measurements: Tests with the Habitable-zone Planet Finder
Insufficient instrument thermo-mechanical stability is one of the many roadblocks for achieving 10cm/s Doppler radial velocity (RV) precision, the precision needed to detect Earth-twins orbiting Solar-type stars. Highly temperature and […]
Acoustic Properties of Glacial ice for Neutrino Detection and the Enceladus Explorer
Ultra high energy neutrinos may be observed in ice by the emission of acoustic signals. The SPATS detector has investigated the possibility of observing GZK-neutrinos in the clear ice near […]
The SERENDIP III 70 cm Search for Extraterrestrial Intelligence
We employed the SERENDIP III system with the Arecibo radio telescope to search for possible artificial extraterrestrial signals. Over the four years of this search we covered 93% of the […]
