Green bank telescope9/27/2023 Ron was truly excited about this discovery, and I know he would have been proud of the result. Michael Busch said, “Ron was an incredible mentor, a brilliant astronomer, and a great friend to me… I will miss him dearly.” Engelke added, who completed his doctorate in 2019, “We were very lucky to have known him. So his former PhD students stepped in and finished the work for publication in the Astrophysical Journal. However, Allen died in August 2020, just as his research was being drafted. The find dates back to 2012, when astronomer Ron Allen, a professor with the Physics and Astronomy Department of Johns Hopkins University, stumbled across emissions that led to the discovery. ![]() NASA wants to tackle the stinky challenge These observations had proven, the accidental finding was a real thing.Īccording to the GBT staff, “the existence of this massive structure has implications for star formation theories, as well as the structure, make-up, and total mass of the interstellar medium.”Īstronauts don’t do laundry in space. The researchers went through another exhaustive 100 hours of observations at many different points across parts of the galaxy and found that it has a similar shape and extent of other components known about within the galactic structure. 5: A new, broad, and faint structure from the OH molecule–in and between the spiral arms. 1-4: Typical narrow-line emission from the OH molecule from spiral arms. “To be even more sure, we tried several different independent signal processing techniques on the GBT and 20-meter results to attempt to remove the feature as if it were from the instrumental background, rather than a real signal, and none of these methods managed to remove it,” said researcher Philip Engelke. Right now, the people doing the research believe the structure extends far into the distant parts of the Milky Way galaxy. Since the GBT has a high level of sensitivity, it was able to detect this extremely large structure that’s made up of molecular gas, versus a physical moon or planet. Essentially, the astronomers are able to see things with the world’s largest fully steerable radio telescope, which looks like a large dish. This discovery was made using radio spectrum. Sometimes, in our galaxy, not everything is visible to the naked eye and that’s what is happening here. The first discovery happened with a smaller telescope but researchers had to bring in a larger, 20-meter telescope to confirm the unexpected observation. ![]() ![]() Pregnant Spring Hill mother severely burned by firework at 4th of July party warns to put safety first
