Kind of supernovae

FOUND ONLINE: In 2011 a team of astronomers used just this kind of supernovae to measure luminosity independently of distance -- and in the process, discover the existence of dark energy.

I wonder why they used supernovae, the plural form of supernova. I see no reason to do so. I think supernova would have worked fine here.
