* Officially Recognized: The International Astronomical Union (IAU), the governing body of astronomy, recognizes 88 constellations. These are the ones you'll see on star charts and are used by astronomers worldwide.
* Historically: Throughout history, different cultures have recognized different constellations, some overlapping with the IAU's list and some entirely unique.
* Modern: Some modern stargazers use unofficial "constellations" based on patterns they observe, especially in areas with fewer bright stars.
So, the short answer is: 88 constellations are officially recognized by the IAU, but many more have been observed and used throughout history.
