       | so... what IS this patch of space with few stars?
       | 
       | it seems like just a patch of space with few stars and the
       | article didn't give any details as to the formation or reasoning
       | for its existence

       | Very interesting. Fortunately we have a new toy to look at it

       | The picture in the article is misleading. It's an image of the
       | Barnard 68 molecular cloud that has nothing to do with Bootes
       | void.
       | 
       | Also, the existence of the void is not at tension with LambdaCDM,
       | the standard model of cosmology, as the article seems to suggest.

         | Also the article is garbled and gibberish.

         | It says so in the first line: "Gas cloud Barnard 68 gives us an
         | idea of what a space void might look like if we could peer
         | through the stars at one."

           | But that statement itself is very misleading, because it's
           | using an _opaque_ gas cloud as an illustration of an _empty_
           | , transparent region of space.

         | The entire article and the website seems kind of autogenerated

           | A "this website doesn't exist" situation maybe. It makes
