Astronomers Apply New AI Technique to Accelerate the Search for Extraterrestrial Life

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.

Planetary Defense & Science Will Advance With New Radar on Green Bank Telescope

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.

Scientists Reveal Secrets to Burping Black Hole with the Green Bank Telescope

The National Science Foundation’s Green Bank Telescope (GBT) has revealed new information about mysterious radio bubbles surrounding a supermassive black hole.  

Observations by NASA’s Chandra X-ray Observatory (left image) and by GBO’s MUSTANG-2 instrument (right image) clearly show the enormous cavities (highlighted with gray circles) excavated by the powerful radio jets (green contours) expelled from the black hole at the center of galaxy cluster MS0735. The green contours in both images are from observations performed by the Naval Research Laboratory’s VLA Low-band Ionosphere and Transient Experiment (VLITE) back end used on the National Radio Astronomy Observatory’s (NRAO) Very Large Array (VLA).
