This is how they found the “structures” and a bit more on what they think they might be?
The detection of these structures was made by astronomers working at the CSIRO’s Compact Array telescope in eastern Australia. Although previous research had hinted at their presence before, this new paper – published in the journal Science – helps to constrain their size and shape a bit better.
Don’t think these are big, solid objects though. Essentially, the structures appear to be large clumps of some sort of material, possibly clouds of cool gas, in the existing thin gas that lies between stars. And they appear to be in odd shapes. The astronomers described them as looking like hollow “noodles” or hazelnuts – with material on the outside and a hollow center. Some may even be sheet-like, and we could be looking at them edge-on.
What do you think these are? Feel free to comment with your ideas and check back for updates on this story.
