A Message from the Green Bank Observatory Director

Looking back on 2020 it was not the year we would have wanted – the many losses of the COVID-19 pandemic and the loss of Arecibo being just two of the many catastrophes the world experienced. But it was not all bad. During 2020 Green Bank Observatory hired a number of fantastic new staff members, found new ways of reaching out to the science community and the public through online biweekly science talks, public demonstrations, tours, and workshops, and continued to produce great science throughout the year. 

While pandemic concerns remain our highest priority, 2021 promises to be a productive year for Green Bank Observatory. In the coming year we will begin work on our new data archive and Cyclic Spectroscopy project, both of which are described later in this newsletter. We will also be fully commissioning LASSI, a new laser-based scanning system which will result in significantly improved performance of the GBT’s surface for high frequency observers. And last but not least, we anticipate commissioning two new receivers – a new, higher stability X-band (10-12 GHz) receiver and a new Ultra-Wideband  (0.7-4.2 GHz) receiver.  

Happy New Year, and I hope all of you have a safe and happy 2021. – Dr. Karen O’Neil

The Decommissioning and Collapse of the Arecibo Telescope

Saddened by the announcement of the decommissioning of the Arecibo Telescope and by its collapse just a few days later, the Green Bank Observatory joined with NRAO to share a statement with the community. See the joint statement here. 

The Arecibo radio telescope had a long and distinguished history of landmark contributions to astronomy and planetary science and often has been a valued partner with NRAO telescopes and the Green Bank Telescope in research projects. Its loss is a blow to science. The staff and facilities of NRAO and GBO stand ready to assist in filling the gap that this absence creates, and offer our best wishes to our colleagues who are affected by this development. See Observatory site director Dr. Karen O’Neil comments in a recent interview.

Blowing in the Wind: Fast Molecular Clouds in the Galactic Center

The GBT was part of an international study that discovered carbon monoxide molecules in the Milky Way’s nuclear wind. Most large galaxies like the Milky Way have hot fast winds blowing from their centers, but only in the Milky Way can these winds be studied up close and in detail. This finding gives new information on the mass flow and energetics of the wind, and on its origin and fate. Read the full release here.
