A signal originally detected by the Kepler spacecraft has been validated as an exoplanet using the Habitable-zone Planet Finder (HPF), an astronomical spectrograph built by a Penn State team and recently installed on the 10m Hobby-Eberly Telescope at McDonald Observatory in Texas. The HPF provides the highest precision measurements to date of infrared signals from nearby low-mass stars, and astronomers...

Data from a massive search for cosmic radio emission released Feb 14. by the Breakthrough Listen Initiative—the most comprehensive survey yet of radio emissions from the Milky Way—has allowed astronomers to look for technological signatures of extraterrestrial civilizations that might be looking for us. Breakthrough Listen—based at the University of California, Berkeley—announced the public release of the...

A new instrument funded by NASA and the National Science Foundation called NEID (pronounced “NOO-id”; sounds like “fluid”) will help scientists measure the masses of planets outside our solar system – exoplanets – by observing the gravitational pull they exert on their parent stars.

The exoplanet-hunting instrument NEID, designed and built at Penn State, has passed an important milestone on the road to discovering Earth-mass planets beyond our solar system. The new instrument, an extreme precision radial velocity spectrometer, has been installed on the 3.5-meter WIYN telescope at Kitt Peak National Observatory (KPNO) in Southern Arizona, a program of the NSF’s National...

Professor Didier Queloz (University of Cambridge and University of Geneva) gave an inspiring talk to the Penn State Center for Exoplanets & Habitable Worlds, along with many students from the Penn State Astrobiolgoy Research Center. As a graduate student at the University of Geneva, Queloz co-discovered the first extrasolar planet orbiting a sun-like star in 1995. That discovery was recently...

The NEID spectrometer passed its NASA pre-ship review. The outcome of this review, held September 17 and 18th at Penn State, was unanimous that the NEID spectrometer meets its requirements and is ready to ship – and had many positive things to say about the technical level of the project and the significant contributions made by our graduate students and postdoctoral fellows. NASA now has to weigh...

A new study provides the most accurate estimate of the frequency that planets that are similar to Earth in size and in distance from their host star occur around stars similar to our Sun. Knowing the rate that these potentially habitable planets occur will be important for designing future astronomical missions to characterize nearby rocky planets around sun-like stars that could support life. A paper...

A new astronomical spectrograph built by a Penn State-led team of scientists provides the highest precision measurements to date of infrared signals from nearby stars, allowing astronomers to detect planets capable of having liquid water on their surfaces that orbit cool stars outside our Solar System. The Habitable Zone Planet Finder (HPF) allows precise measurement of a star’s radial velocity, measured...
