Scientists map the Milky Way Galaxy in exceptional detail
There have been detailed maps of the Milky Way before, but none quite so ornate as this. Researchers in the HI4PI sky survey have created a fine-grained map of our home galaxy using its most common material: neutral atomic hydrogen. Such studies have taken place before, as you might guess. However, the use of 10 billion data points from large radio telescopes (the Parkes Observatory and Effelsberg 100m) and noise-filtering algorithms have produced an image with twice the sensitivity as the previous best, and four times the angular resolution. The result? A view of the Milky Way so comprehensive that you can finally see the finer details of cloud structures in between stars -- they were too blurry before.
