Nestled in the hills in Pocahontas County, West Virginia, is the Green Bank Telescope. At 485 feet tall and about 300 feet across, it’s the largest fully-steerable telescope in the world, and it belongs to Green Bank Observatory.
Since the observatory opened in 1957, researchers have used the facility to make several discoveries, like organic prebiotic molecules — the building blocks of life. The Green Bank Telescope is also one of only two radio telescopes in the world searching for signs of intelligent life in space.
Breakthrough Listen is the largest ever scientific research program aimed at finding evidence of civilizations beyond Earth. The scope and power of the search are on an unprecedented scale:
The program includes a survey of the 1,000,000 closest stars to Earth. It scans the center of our galaxy and the entire galactic plane. Beyond the Milky Way, it listens for messages from the 100 closest galaxies to ours.
The instruments used are among the world’s most powerful. They are 50 times more sensitive than existing telescopes dedicated to the search for intelligence.
The radio surveys cover 10 times more of the sky than previous programs. They also cover at least 5 times more of the radio spectrum – and do it 100 times faster. They are sensitive enough to hear a common aircraft radar transmitting to us from any of the 1000 nearest stars.
The GBT plays a key role in the Breakthough Listen project, and roughly 20% of the time available on the GBT is dedicated to this research.
Breakthrough Listen is also carrying out the deepest and broadest ever search for optical laser transmissions. These spectroscopic searches are 1000 times more effective at finding laser signals than ordinary visible light surveys. They could detect a 100 watt laser (the energy of a normal household bulb) from 25 trillion miles away.
Listen combines these instruments with innovative software and data analysis techniques.
The initiative will span 10 years and commit a total of $100,000,000.

But today, the telescope and the facility that supports it are under federal review — with the possibility of losing funding or being dismantled.
In the face of that threat, one West Virginia family hopes to convince the powers that be of the facility’s value to science, education and the small town in which the telescope resides.
“It’s almost like a tiny metropolitan city in the middle of rural West Virginia,” said Ellie White, a 16-year-old from Barboursville, West Virginia. “That kind of resource is invaluable for kids across the state and across the country, who are going to be tomorrow’s innovators, engineers, scientists, politicians, artists.”
White’s family volunteered to start a campaign called Go Green Bank Observatory to rally support from across the country and show the National Science Foundation, which used to almost completely fund the observatory, that Green Bank Observatory is worth keeping. In 2012, the NSF published a portfolio review that recommended at least partially divesting from several observatories around the country that no longer have as large of a scientific impact as they used to. Green Bank Observatory was on that list.
Proposed operational changes for Green Bank Observatory range from continuing to partially fund its operations to shutting down its research operations and turning it into a technology park, or completely tearing it down.
“This is one of the difficult things the NSF has to do,” said Edward Ahjar, an astronomer at the NSF. “All of our facilities do great science, and that’s why we fund them. But when we start having less and less money to spread around, then we have to prioritize them. Which are doing the most important science now? Which are lower ranked?”
The Fight to Keep Green Bank Observatory Open
Last fall, Go Green Bank Observatory encouraged fans to speak at two public scoping meetings where Ahjar and other representatives from the NSF would be present to hear the public’s input about the divestment process.
About 350 people filled the seats of an auditorium at the observatory. Several in attendance were affiliated with West Virginia University, which since 2006 has received more than $14.5 million in grant dollars for research related to the Green Bank Telescope.
“When I started applying for graduate school, WVU was one of my top choices,” said Kaustubh Rajwade, a graduate student from India in the Department of Physics and Astronomy at WVU. “The only reason I came here was so I could use the Green Bank Telescope.”
Others, like Buster Varner, a local fire chief, were more concerned about Green Bank Observatory’s role in the community as a de facto community center, where people can hold meetings and classes.
“Whenever we had a catastrophe, we can go to Mike,” Varner said, referring to Mike Holstine, the business manager at Green Bank Observatory. “I don’t know much about this science, and there’s a lot of people here who does and that’s great. But I do not want anything to happen to this facility, period.”
The NSF once almost completely funded Green Bank Observatory’s operations. But Holstine said that especially in the past five years, the observatory saw a need to diversify its sources of funding — in part because outside organizations and researchers expressed a willingness to pay for time on the telescope, but also due to the clear indicators that the observatory needed to rely less on the NSF.
Green Bank Observatory employs between 100 and 140 people — more than half of whom are from Pocahontas County — depending on the time of year. The money also helps the observatory maintain its own infrastructure in an isolated and rural area.
“You kind of need to think of us as a town, a self-contained town,” Holstine explained. “We have our own roads. We have our own water system. We have our own wastewater system. We take care of our own buildings. We mow our own grass; we cut our own trees. We have to plow snow in the winter.”
A Future Without Green Bank Observatory
For White, the Observatory isn’t only worth keeping because of its accomplishments — but also because of its efforts to train the next generation of scientists. When she was younger, White was convinced she wanted to be an artist when she grew up. But since playing among the telescopes as a child, she has gone on to work on projects under the mentorship of astronomers and graduate students from all over the world.
She’s not the only teen who’s been impacted by the observatory’s work; through the Pulsar Search Collaboratory, more than 2,000 high school students have worked with the Green Bank Observatory through a partnership with West Virginia University since 2007.
“Just generally being here, you learn something every day. It’s like learning a new language through immersion,” White said.
The NSF will reach its decision about the Green Bank Observatory’s fate by the end of this year or the beginning of next year. At 16 years old, White hopes to get her doctorate in astrophysics and one day find full employment at the observatory. If it shuts down, White said, she might have to look for employment out of state.

Green Bank Observatory enables leading edge research at radio wavelengths by offering telescope, facility and advanced instrumentation access to the astronomy community as well as to other basic and applied research communities. With radio astronomy as its foundation, the Green Bank Observatory is a world leader in advancing research, innovation, and education.
60 years ago, the trailblazers of American radio astronomy declared this facility their home, establishing the first ever National Radio Astronomy Observatory within the United States and the first ever national laboratory dedicated to open access science. Today their legacy is alive and well.
