GBT & FAST reveal new origins of bright radio flashes in the Universe
Scientists using the National Science Foundation’s Green Bank Telescope (GBT) and China’s Five-hundred-meter Aperture Spherical radio Telescope (FAST) have teamed up to shed light on the origin of the thousands of mysterious fast radio bursts that hit the Earth each day from locations far beyond the Milky Way.

Are we alone? New grant supports citizen science searching for intelligent life with the GBT
The Planetary Society has awarded nearly $50,000 to UCLA Professor Jean-Luc Margot for a new citizen science project using the Green Bank Telescope (GBT), “Are We Alone? A Citizen-Science-Enabled Search for Technosignatures.”

Robust Gas Measurements for BreakBRD Galaxies
The general view of galaxy quenching is that it takes place from the inside-out, explaining the commonality of non-star forming bulges and actively star forming disks across the galaxy population. However, a fraction of apparently quenching galaxies display opposite behavior: actively star forming bulges and non star-forming disks. These galaxies are dubbed BreakBRDs (“Break Bulges…

Orion rising over GBT (taken by WV photographer) is NASA’s Astronomy Photo of the Day
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.

New ‘black widow’ millisecond pulsar discovered
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.

Diffuse Molecular Galactic Disk Survey
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…

GLUCOSE — The GBT L1544 Unbiased Complex Organics SurvEy
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 — GBT Diffuse Ionized Gas Survey at Low Frequencies
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…
