I'm guessing that it's a TV show or movie called "Cyberspace" and its being shown on TV or the cinema. We often refer to something being on TV in this way.

Awww, thank you so much!

The phrase "Cyberspace is on this week" is not a common or widely recognized expression in the English language, and its meaning may depend on the context in which it is used. In a general sense, "Cyberspace" refers to the virtual environment of computer networks and the internet. "On this week" could suggest that there are events, activities, or important developments related to cyberspace happening during the current week. However, without more context, it's challenging to provide a precise interpretation of this phrase. The meaning could vary depending on the specific conversation or situation in which it is used.
