"An analysis of public data from a NASA satellite turns up massive, previously unseen galactic structures"
The article talks about how a group of astrophysicists located two bubbles of plasma the size of tens of thousands of light years, which are emitting high energy radiation. The researchers found these with a new telescope, which can gather data from not only x-rays, but now also gamma rays, which have higher frequencies.
This is very interesting, because the more advanced our technology gets, the more we discover, like for example these bubbles of plasma that were actually in plain sight from us. These bubbles of plasma could be a star forming right before out eyes.
