That's an "end of sentence period". This is only relevant for some
languages (such as English) where periods at the end of sentences have
more space than within sentences (e.g., after abbreviations).

LaTeX automatically inserts such longer spaces only after lowercase
letters. So if your sentence ends with an uppercase letter ("This is
Richard III.") or a number, you'll need this (in English).

Vice versa, you need a "normal space" (Ctrl+Alt+Space, LateX "\ ")
after periods following lowercase letters within sentences (e.g., with
abbreviations).
