Astronomers study the universe by capturing light from the sky, but they can also learn thing by sending radio light into space.

NRAO, Green Bank Telescope, and Raytheon Intelligence & Space (RI&S) are working in collaboration to improve planetary radar capabilities. With the addition of Qorvo’s Spatium power amplifier technology, the project now has the power to identify and characterize even small NEOs earlier with more precision.

Collaboration between the National Radio Astronomy Observatory, the Green Bank Observatory, and Raytheon Intelligence & Space turns the Green Bank Telescope and the Very Long Baseline Array into a radar system for studying the Solar System.

Astronomers using the GBT have discovered the most massive neutron star to date, a rapidly spinning pulsar approximately 4,600 light-years from Earth. This record-breaking object is teetering on the edge of existence, approaching the theoretical maximum mass possible for a neutron star.

Radio telescope observations have made it possible for astronomers to use mergers of neutron-star pairs as a valuable new tool for measuring the Universe’s expansion.

Harnessing the exquisite sensitivity of the GBT, astronomers have given one of Einstein’s predictions on gravity its most stringent test yet. By precisely tracking the meanderings of three stars in a single system – two white dwarf stars and one ultra-dense neutron star – the researchers determined that even the most massive of objects “fall” in the same manner as their less-dense counterparts.

Astronomers using the GBT have made the first definitive interstellar detection of benzonitrile, an intriguing organic molecule.

VLA points to previously unknown galaxy cluster, GBT gets new vision, and ALMA uses double vision.

Scientists applaud discovery of “handed” molecules in interstellar space.

NANOGrav provides insights into galaxy mergers.
