Researchers at Penn State's Extraterrestrial Intelligence (PSETI) Center have been awarded a $480,000 grant under NASA's Exoplanets Research Program. This three-year project will focus on detecting radio and laser signals that could indicate the presence of alien civilizations. The initiative is led by doctoral student Pinchen Fan, supported by her adviser, Jason Wright, professor of astronomy and astrophysics and director of the PSETI Center.
"This NASA grant marks a significant milestone for both Penn State and the broader field of the search for extraterrestrial intelligence (SETI)," Wright said. "This area of research has been historically underfunded by NASA but is now seeing a resurgence in attention and support. The PSETI Center is uniquely positioned to lead this exploration, thanks to Penn State's support, NASA's support and the dedication of researchers like Pinchen, who will be driving much of this project forward."
In 2018, Wright facilitated a NASA workshop in Houston to explore strategies for the agency's involvement in the search for technological life. The current grant builds on the momentum generated by that event, signaling NASA's increasing commitment to innovative SETI research approaches.
"The renewed interest from NASA is a game-changer for SETI research," Fan said. "It provides us with the resources and support needed to push the boundaries of our understanding and explore uncharted territories in the search for extraterrestrial intelligence."
The project aims to refine techniques for detecting technosignatures – detectable signs of intelligent life beyond Earth. Researchers will develop advanced methods for identifying laser and radio technosignatures from exoplanets.
"We will analyze the patterns of humanity's most powerful deep-space radio transmissions as a baseline for understanding the patterns of a civilization's transmissions to its own interplanetary probes," Fan said. "We will use these patterns as a guide to how we might eavesdrop on radio transmissions from other spacefaring civilizations that are not specifically intended for Earth."
In addition, Fan will analyze infrared spectroscopic data from the Habitable Zone Planet Finder (HPF), a state-of-the-art instrument developed at Penn State. The HPF, installed on the Hobby-Eberly Telescope in Texas, has been used to identify exoplanets and will now assist in detecting potential laser communications from alien civilizations.
"Humanity has been moving towards laser communications for interplanetary communications for a while now," Fan said. "It makes sense that other species might do the same, so we are excited to use the HPF for this novel search."
"There is a long tradition of SETI searches piggybacking on surveys at the radio wavelengths," added Suvrath Mahadevan, Verne M. Willaman Professor of Astronomy and Astrophysics and principal investigator of the HPF spectrometer. "It is great to see this approach now used in the near-infrared with HPF to search for laser transmissions."
This NASA funding underscores Penn State's leadership in the SETI field, which has gained increasing recognition within the scientific community. The 2018 workshop and subsequent SETI Symposia hosted by the PSETI Center have been pivotal in renewing NASA's focus on this research.
"NASA's support for our technosignature research reflects both the growing scientific credibility and public interest in SETI," Fan said. "I'm excited to contribute to Penn State's leadership in this field and to develop new techniques that could bring us closer to finding extraterrestrial life."
Founded in 2020, the PSETI Center has established itself as an academic leader in technosignature research. It provides a platform for developing innovative detection methods, fostering interdisciplinary collaborations, and training the next generation of SETI researchers. Members of the center are also building an academic curriculum focused on SETI at both undergraduate and graduate levels.
"This grant from NASA highlights a pivotal moment in the advancement of SETI as a scientific discipline and the pioneering work being done at Penn State," Wright said. "With renewed support, innovative ideas, and a team of dedicated researchers, Penn State is well positioned to lead in the quest to uncover evidence of intelligent life beyond Earth."
"I'm eager to see where this journey takes us," Fan said. "Every step we take brings us closer to potentially answering the age-old question: 'Are we alone?'"
