And get an accurate distance to it. For example wikipedia says WR 25
is about 7500 lightyears away. Once you've converted through from
milli arcseconds (mas) Gaia says 68500 (divide by a 1000 then divide 1
by that number to get the parsecs distance then multiply by 3.26 to
Beyond stars the improved Cepheid variable measurements will allow us
to update the https://en.wikipedia.org/wiki/List_of_nearest_galaxies article with better data and hopefully get a new study on what is an
