Today, a European Space Agency used an infrared telescope and found a hole in space. This hole has provided astronomers with a look into the end of the star-forming process. The cloud that Herschel looked into appeared black. They investingated into it and saw there was a hole right through the cloud. Scientists think it formed around 1999.
I think it is a hole in space. If there is a hole in a cloud then where does it lead to? Apparently it has to go to the space and there must be a hole there too. I think that the hole was formed by a jet stream. This could be a reason because many rockets go through clouds and always make a hole.
