An article published in the journal “Science” describes a research about two very young galaxies that probably look very wimilar to the Milky Way 12 billion years ago. Called ALMA J081740.86+135138.2 and ALMA J120110.26+211756.2, they were observed by a team of astronomers using the ALMA radio telescope as a follow-up of previous research conducted using the light from a quasar behind the two galaxies. The new research showed that the two galaxies are surrounded by a halo of gas and that their star formation rate is rather high.
