Are we alone in the universe?
Scientists may have just moved us closer to answering this question. The team – led by researchers from the University of Toronto – has streamlined the search for extraterrestrial life by using a new algorithm to organize the data from their telescopes into categories, to distinguish between real signals and interference. This has allowed them to quickly sort through the information and find patterns, through an artificial intelligence process known as machine learning.

Drake Lecture
Dr. Frank Drake, the Lectureship’s namesake, has had a long and distinguished career that began at the Observatory in Green Bank. His scientific achievements include discovery of the radiation belts of Jupiter, and the measurements and characterization of the radio sources at the center of the Milky Way. He also contributed to our understanding of the high surface temperature of Venus. In 1960, using a radio telescope at Green Bank, he made the first modern search for radio signals from extraterrestrial civilizations, He thus began an area of scientific research that has continued and is flourishing today, engaging creative minds worldwide.
To honor Drake’s impact on the public understanding of science, an award was established in 2019. A scientist who has made significant contributions to society, inspiring others to explore the mysteries of the Universe, is selected each year to share a lecture about their work.

NSF and SpaceX Finalize Radio Spectrum Coordination Agreement
The National Science Foundation (NSF) and SpaceX have finalized a radio spectrum coordination agreement to limit interference from the company’s Starlink satellites to radio astronomy assets operating between 10.6 and 10.7 GHz. The agreement, detailed in a statement released by NSF today, ensures that Starlink satellite network plans will meet international radio astronomy protection standards, and protect NSF-funded radio astronomy facilities, including the National Radio Astronomy Observatory (NRAO) and the Green Bank Observatory (GBO). The agreement will also positively impact collaborations and cooperation between SpaceX and NSF’s NOIRLab.

With less power than a microwave, prototype produced highest resolution images of Moon ever captured from Earth
With a transmitter less powerful than a microwave oven, a team of scientists and engineers used the National Science Foundation’s Green Bank Telescope (GBT) and Very Long Baseline Array (VLBA) to make the highest-resolution radar images of the Moon ever collected from the ground, paving the way for a next-generation radar system to study planets, moons, and asteroids in the Solar System.
