Astronomers need many tools and hundreds of hours of observation to confirm this. A large structure lurks in the interstellar medium that fills the Milky Way. A thick disk of “black” molecular gas located at the tip of our galaxy.
It’s a story as much as we love them. Of what Fireside can tell. No, not scary kids. But among those who amaze them and perhaps lead them to science one day. This story is the story of these grateful researchers Green Bank Telescope (GBT), with a little help from fate, now found and hidden , A large structure.All rights reserved
But in 2012, an astronomer at Johns Hopkins University in the United States unexpectedly discovered an unrelated job. . Suppose there is a large portion of dehydrogen that cannot be detected by CO. A type of molecular gas CO-dark.From OH molecules that do not emit CO. Or OH is also a visible molecule H2 Since
All observations confirm it
This is where BGT comes in. In 2015, he enabled a team of astronomers, and OH finds this element very well. CO-dark You h2. After exposure time, researchers have shown that this molecular gas is an important component of the structure of the Milky Way.
But the story does not end there. Astronomers noticed a bump that stood out from their observations. They initially believed that it corresponds to the end of A. . Observations confirmed the existence of a vapor structure, but permeated the entire view of the BGT. Astronomers thought of an outcome Yourself. Like background noise. However, after a hundred hours of observation, the Green Bank Observatory’s 20-meter telescope – an older device than the BGT – also found a suspicious structure.
Finally, in 2019, a new series of observations came to confirm the finding. A previously unknown but large, ubiquitous structure on the Milky Way disk fits the shape of other components of our galaxy. A discovery that has implications for star formation theories, but also for those interested in structure and structure.Of interstellar media.
