Reviving SETI with High-Energy Astronomy What new methods can be developed in the search for extraterrestrial intelligence (SETI)? This is what a recent white paper submitted to the 2025 NASA Decadal Astrobiology Research and Exploration Strategy...

A false-color image of the Moon from NASA's Compton Gamma Ray Observatory's EGRET instrument. The Moon appears brilliantly bright due to gamma rays produced by cosmic rays impacting its surface, brighter than the Sun at these wavelengths. The image shows a wide field of view, also including gamma-ray emissions from the Milky Way galaxy and other sources.

False-color images of the Galactic center in X-ray (left) and gamma-ray (right) light, revealing a cluster of high-energy sources, likely binary star systems with black holes. The absence of a bright source at the exact Galactic center is surprising. Data from the SIGMA telescope aboard the GRANAT spacecraft (1990-1997).

A pixelated image of Earth in gamma rays, captured by the Compton Gamma Ray Observatory. The bright edges show gamma rays produced by the atmosphere interacting with cosmic rays. This image is a compilation of 7 years of data, demonstrating the faint gamma-ray glow of our planet.
