West Virginia photographer Dave Green created the amazing astrophotography image seen above, which shows the constellations of Barnard’s Loop, the Horsehead, Lambda Orionis, and more above the GBT.
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 arXiv.org.

Is the Broad 18cm OH Emission ‘Disk’ in Concordance with Galactic Structure? We recently published the GBT discovery paper of a large amount of diffuse molecular gas, previously undetected by CO surveys (Busch et al. 2021). Present in sightlines towards the Outer Galaxy was an extremely faint (~2-4 mK/channel) signal of 1667 MHz OH emission […]
A high spectral and spacial sensitivity line survey will be carried out toward the prestellar core L1544 in the chemically rich Q-band (38-48.2 GHz), which has never before been attempted. Within the band are numerous energetically favorable complex organic molecule (COM) transitions compared to those in other surveys at higher frequency (i.e., the 3mm band), […]
GDIGS-Low is a survey that will map radio recombination line (RRL) emission at 800 and 340 MHz over the inner Galactic plane (32° > ℓ > -5°). GDIGS-Low is a complement to the GDIGS survey. Through GDIGS-Low we will study the Warm Ionized Medium (WIM) and aim to answer (i) What are the physical properties […]
