(more…)A New Era for Green Bank Observatory, Dr. James M. Jackson Named Director

The Green Bank Observatory (GBO) enters a new era of leadership in October. Dr. James M. Jackson, an internationally known astrophysicist, has accepted the role of director.
After serving as director for 15 years, Dr. Karen O’Neil will join the scientific staff. O’Neil has led the Observatory since 2006, including overseeing the separation from the National Radio Astronomy Observatory (NRAO) and the successful transition to Green Bank Observatory in 2016. She looks forward to being a longstanding member of the Observatory staff and being a vital part of its continued growth.

The tumultuous evolution of a galaxy cluster captured close to its formation in the cosmic web

An international team of astronomers using the National Science Foundation’s Green Bank Telescope (GBT) in Green Bank, West Virginia, and the NASA’s Chandra X-ray Observatory have captured a snapshot of a massive galaxy cluster, very close to the epoch when it began to emerge from the cosmic web.

Incredibly sensitive spectral observations from the Green Bank Telescope discover previously unknown huge Galactic structure

When it comes to the Universe, there is more than meets the eye. Astronomers using the National Science Foundation’s Green Bank Telescope (GBT) have discovered a massive, previously unknown structure in our Galaxy. This discovery was so unexpected, additional observations were taken using the Green Bank Observatory’s 20-meter Telescope to confirm the data.

How long is a day on Venus? Scientists crack mysteries of our closest neighbor

Venus is an enigma. It’s the planet next door and yet reveals little about itself. An opaque blanket of clouds smothers a harsh landscape pelted by acid rain and baked at temperatures that can liquify lead.
Now, new observations from the safety of Earth are lifting the veil on some of Venus’ most basic properties. By repeatedly bouncing radar off the planet’s surface over the last 15 years, a UCLA-led team has pinned down the precise length of a day on Venus, the tilt of its axis and the size of its core. The findings are published today in the journal Nature Astronomy.

Astronomical surveys mapping regions of the Galaxy have been collected and studied for decades. These surveys allow researchers to compare previous data, further characterize objects or images of the sky, and learn more through statistical analysis. For the National Science Foundation’s Green Bank Telescope (GBT) Diffuse Ionized Gas Survey (GDIGS), researchers took advantage of the power of the GBT, located in Pocahontas County, West Virginia, to better understand the impact of massive stars in the Milky Way.

How would you feel if you could talk to an astronaut, orbiting over 200-miles above you in space?
Friday, May 7th at 8:00 AM EDT, students in rural West Virginia will experience this once in a lifetime opportunity. Green Bank Elementary-Middle School (GBEMS) will be contacting astronaut Mark Vande Hei on the International Space Station (ISS).

Observatory staff lead new sustainability intiatives

The Green Bank Observatory employees established a sustainability committee in late 2020 to develop new initiatives for local residents to improve their environment and their lives.
Can Green Bank Telescope Defend Against Asteroid Apophis?

The National Science Foundation’s Green Bank Telescope (GBT) is teaming up with NASA’s Goldstone Deep Space Communications Complex (GDSCC) to observe this potentially hazardous asteroid. These new observations of Apophis will allow scientists to improve their understanding of the asteroid’s orbit, and better estimate the odds that Apophis could strike the Earth in the future. Predicting if there is a real chance of impact, decades ahead of time, gives scientists the opportunity to take action to manipulate the orbit of Apophis to avoid a collision in the future.

This “waterfall image” is actually three separate observations combined to show NASA’s Mars Perseverance rover as it enters the Martian atmosphere before touching down on the red planet. Green Bank Observatory Data Analyst Amber Bonsall created this image using data received by the Green Bank Telescope (GBT). The GBT was pointed at Mars to observe communications from the rover as it landed February 18th, 2021 at 3:55 p.m. EDT.

The Green Bank Telescope’s Part in the NASA Perseverance Mars Rover Landing

GREEN BANK, WEST VIRGINIA – Cheers could be heard throughout the Green Bank Observatory as NASA’s Mars 2020 Perseverance rover successfully touched down on the red planet Thursday, February 18th, at 3:55 p.m. EDT. The National Science Foundation’s Green Bank Telescope (GBT) helped relay communications from the rover to NASA’s Jet Propulsion Laboratory (JPL) located in southern California.

West Virginia’s Role in the NASA Perseverance Mars Rover Landing

The National Science Foundation’s Green Bank Telescope (GBT), located in Green Bank, West Virginia, plays a role in the upcoming mission of the NASA’s Mars 2020 Perseverance rover. The GBT will receive communications from the rover as it arrives on Mars on February 18th and pass these on to NASA’s Jet Propulsion Laboratory (JPL) located in southern California.

Volunteers Build Bird Boxes to Support Local Ecosystems & Citizen Science
This past spring, the Green Bank Observatory and the Appalachian Forest National Heritage Area hosted an event with the Deer Creek Defenders 4-H club to build nesting boxes for the Green Bank and Arborvale bird population. This project was managed by AmeriCorp staffer Joe Medica.

Green Bank Student Scientists Launch Massive Balloon for Airborne Experiments
Budding scientists in Green Bank, West Virginia will embark on a new mission next week. Students in Ms. Brown’s 7th grade class have planned extensively to launch a 12-foot diameter, high altitude helium balloon to conduct several scientific experiments.

Celebrate the Supermoon Total Lunar Eclipse at Green Bank Observatory

Sunday, May 15th a total lunar eclipse of a supermoon will be visible to most of us in West Virginia (weather permitting) between the hours of 10:30pm and 2am Eastern Time. The start and end of the lunar eclipse’s ‘totality’ is between 11:30pm and 1am. No special equipment is needed to view a lunar eclipse, although an optical telescope or binoculars can make it more exciting!

Powerful radar systems have played a major role in the study of planets, moons, asteroids, and other objects in our Solar System for several decades, and now have a “unique role” to play in planetary defense – “providing protection to the nations of the world from devastating asteroid and comet impacts,” according to the newly released Planetary Science and Astrobiology Decadal Survey 2023-2032. The National Radio Astronomy Observatory (NRAO) and the Green Bank Observatory (GBO) are developing new capabilities for the Green Bank Telescope (GBT) and the Very Long Baseline Array (VLBA) that will make them key instruments for meeting this need.
