Astronomers using the Green Bank Telescope have made the first definitive interstellar detection of benzonitrile, an intriguing organic molecule that helps to chemically link simple carbon-based molecules and polycyclic aromatic hydrocarbons. This discovery is a vital clue in a 30-year-old mystery: identifying the source of a faint infrared glow that permeates the Milky Way and other galaxies.

Astronomers had a mystery on their hands. No matter where they looked, from inside the Milky Way to distant galaxies, they observed a puzzling glow of infrared light...

Analysis of Green Bank Telescope observations made public, including 11 events ranked highest for significance. Breakthrough Listen – the initiative to find signs of intelligent life in the universe – has released its 11 events ranked highest for significance as well as summary data analysis results. It is considered unlikely that any of these signals originate from artificial extraterrestrial sources, but the search continues. Listen has submitted the analysis of 692 stars, comprising all spectral types, observed during its first year of observations with the Green Bank Telescope.

Breakthrough Listen has so far acquired several petabytes of data using the Green Bank Radio Telescope (GBT) in West Virginia, Lick Observatory’s ...
