A minor gripe about the European Southern Observatory’s press coverage of Supernova 1987A. I feel compelled to blog about SN 1987A because today marks the twentieth anniversary of its discovery.

Honestly, I appreciate ESO putting a graph on their web page of images. Even better, it includes color-coded dots with decent labels! But the good news stops there. Two major problems here: the label on the ordinate and the caption for the image.

Why say simply “V Magnitude” when you could add “Brightness” and make the message more clear?

And why cut the caption so short? “Light curve of the Supernova 1987A over a long period of time. Characteristic phases in the evolution of the supernova are indicated.” I mean, “a long period of time”? Just say “more than a decade” (so people don’t have to do the division in their heads). And how ’bout explaining some of those “characteristic phases” while you’re at it? I’d like to know a little more about radioactive tails; they sound kinda interesting.

Anyway, happy birthday, SN 1987A! And many happy returns…
