During its XXX General Assembly in Vienna (in August 2018), the International Astronomical Union (IAU) put forward a draft resolution to rename the Hubble law as the “Hubble–Lemaître law”. The resolution was proposed to recognise Lemaître’s research on the expansion of the Universe, and to pay tribute to both Lemaître and Hubble for their fundamental contributions to the development of modern cosmology. This resolution has now been put to all IAU Junior and Individual Members via an electronic vote.
To acknowledge the fundamental scientific contributions of both Georges Lemaître and Edwin Hubble to the scientific theory of the expansion of the Universe    , the International Astronomical Union (IAU) has proposed a resolution (Resolution B4) that would have the effect of renaming the Hubble law as the “Hubble–Lemaître law”. This resolution was put forward after a period of extensive consultation with the astronomical community and it was one of the most intensely discussed proposals presented at the XXX General Assembly of the IAU.
 The research paper Hubble published in 1929 was titled A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae, and in 1931 it was followed by a paper written in collaboration with Milton Humason, which included additional observational data.
 This research was published in a paper titled Un Univers homogène de masse constante et de rayon croissant rendant compte de la vitesse radiale des nébuleuses extra-galactiques, in French.
 In 1931, at the invitation of the journal Monthly Notices of the Royal Astronomical Society, Lemaître translated his paper from 1927. In it, he omitted the section with the derivation of the distance–velocity relation. Further information on this topic can be found in the article Mystery of the missing text solved by Mario Livio, published in the journal Nature.
 According to historical sources, Lemaître and Hubble both attended the III General Assembly of the IAU in 1928, where they exchanged ideas on the suspicion that observational data may show a correlation between the distance and radial velocity of extragalactic nebulae. A summary of the events that led to the dissemination of the observational confirmation of the expansion of the Universe can be found in the article Discovery of the Expansion of the Universe by Sidney van den Bergh, published in the Journal of the Royal Astronomical Society of Canada.
МАС вынесла эту резолюцию на голосование - и я, как член МАС с 1997 года, за неё сегодня проголосовал:
Ура Леметру и исторической справедливости!
