How can humans protect the Earth from “devastating asteroid and comet impacts?” According to the National Academies and their…
The Baseline #12: Planetary Radar— Shining Light On Our Nearest Neighbors
Radio astronomers usually learn about the universe by passively observing the sky. But sometimes radio astronomy can be a bit more active. Join our host Summer Ash of the National Radio Astronomy Observatory as she talks about how astronomers can use radar to understand our astronomical neighbors in new and interesting ways.
Future of Earth’s Defense is Ground-Based Planetary Radar
The Planetary Science Decadal Survey indicated that new ground-based radar systems will be vital research tools for planetary defense and studying planets, moons, asteroids, and other Solar System objects. The National Radio Astronomy Observatory and the Green Bank Observatory are developing new capabilities for the Green Bank Telescope and the Very Long Baseline Array that will meet those needs.
2021 Science Highlights: Looking Back on a Turbulent Year in Radio Astronomy
The formation of massive stars and planets. The deaths of stars and galaxies. The extreme and violent behaviors of black hole jets and quasars. An up-close and personal radar view of the Moon. These mysteries and more were unraveled in 2021 by radio astronomers leveraging the scientific and technological power of National Radio Astronomy Observatory (NRAO) facilities.
Astronomical Radar: Illuminating our Understanding of the Solar System
Astronomers study the universe by capturing light from the sky, but they can also learn thing by sending radio light into space.
IMAGE RELEASE: Moon’s Tycho Crater Revealed in Intricate Detail
The National Science Foundation’s Green Bank Observatory and National Radio Astronomy Observatory, and Raytheon Intelligence & Space have released new high-resolution images of the Moon, the highest-ever taken from the ground, using new radar technology on the Green Bank Telescope (GBT).
