An international team of astronomers reports the detection of a new millisecond pulsar (MSP) using the Green Bank Telescope (GBT). The newfound pulsar, designated PSR J1555−2908, turns out to be one of the so-called “black widow” MSPs. The finding is detailed in a paper published February 10 on


Microwave Journal: A Planetary Radar System for Detection and High-Resolution Imaging of Nearby Celestial

In partnership with National Radio Astronomy Observatory (NRAO) and Raytheon Intelligence &
Space (RI&S), the Green Bank Observatory (GBO) tested a multi-static radar intended to expand
the scientific reach and capability of the Green Bank Telescope (GBT) and the Very Long Baseline
Array (VLBA).
