This blue point in close center, is a supernova?

Please, help me to differentiate a star from a supernova.

Try Wikipedia. This target AGZ000d7bw [SDSS J091526.45+312354.8 ] is part of a galaxy. It is NOT a star. It is a "starforming" or "starburst" node with many bright stars appearing as one 'stellar' object. Some stars do travel past targets and look like this - it's confusing. Look up the object and that might resolve your issues. click "Galaxy Zoo examine" then "SDSS SkyServer" then "navigate" then click on the object. Use object ID for your question or statement.

Here is another random target at the same red shift https://www.galaxyzoo.org/#/examine/AGZ000d6ne .

Supernovae look much like this, but are greenish. Also, supernovae fade, so check other images to see if it is still there.

Is it a supernova? Check transients with Aladin https://talk.galaxyzoo.org/?_ga=2.197780399.1487098012.1493877526-711441289.1371287491#/boards/BGZ0000007/discussions/DGZ0002gsd
