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.
For the June 2021 meeting several Observatory staff will be sharing presentations, sessions, and iPosters. This list is evolving as the full breadth of meeting items that mention the Green Bank Telescope (GBT) and the Green Bank Observatory are brought to our attention.
These nearby nurseries shed light on the early days of the Universe
Looking up at the night’s sky, twinkling with celestial objects, do you ever dream of discovering something new? How about something that sheds light on the early days of the Universe? A decade ago, citizen scientists, in the Galaxy Zoo project, helped astronomers discover a new and important class of galaxies, the Green Peas.
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.
