15 years of NGC 300 distance

This exact day 15 years ago we published a paper that became a setting stone for our long-lasting project on improving the calibration of the cosmic distance scale in the local Universe.

In this paper Wolfgang Gieren et al. published the distance to a beautiful spiral NGC 300 with a relative error as tiny as 3%. And this is enormously large distance – 1.88 Mpc, over 6 mln light years away!
