Milky Way’s ‘poor old heart’ could reveal how our galaxy formed

Astronomers have found the “poor old heart of the Milky Way” — faint stars that were around when our galaxy was young — lurking deep in the galaxy’s core.

In a new study, astronomers at the Max Planck Institute in Germany compared the most recent data from the European Space Agency’s Gaia mission with data from the LAMOST spectral survey and the APOGEE survey (part of the Sloan Digital Sky Survey), both of which also observe starlight in the Milky Way. Hidden in the survey data were glimpses of the oldest stars in the Milky Way’s heart.
