The formation of our Milky Way can be split up qualitatively into different phases that resulted in its structurally different stellar populations: the halo and the disk components1,2,3. Revealing a quantitative overall picture of our Galaxy’s assembly requires a large sample of stars with very ...
Combined with Gaia measurements of star velocities, the diagram enables astronomers to distinguish between various populations of stars of different ages that are located in different regions of the Milky Way, such as the disc and the halo, and that formed in different ways. Further scrutiny sugges...
However, the current major challenge to reconstructing the chronology of the Milky Way is the difficulty to derive precise stellar ages for large samples of stars. The colour鈥搈agnitude diagram (CMD) fitting technique offers an alternative to individual age determinatio...
This is why NASA plans to launch a probe towards Alpha Centauri in 2069. The intent of this interstellar space mission is to search for biosignatures on planets around the stars in the Alpha Centauri system. Even here in ourMilky Way galaxy, there are at least 10 possible habitable planets....

And the evening and the morning were the first day (of creation, the time used here is God’s time of His planet Kolob in the center of our Milky Way galaxy, which one rotation, one day, of Kolob is equal to 1,000 earth years, See Abraham 3:3-4 and 2 Peter 3:8). And God...
They wouldn’t float like balloons or give you the chance to talk in high, squeaky voices, but planets with helium skies may constitute an exotic planetary class in ourMilky Waygalaxy. Researchers using data from NASA’s Spitzer Space Telescope propose that warm Neptune-size planets with clouds...
Globular Cluster and Galaxy Formation: M31, the Milky Way and Implications for Globular Cluster Systems of Spiral Galaxies There is no ready explanation for the marked difference in nitrogen abundance for old M31 GCs relative to the oldest Galactic GCs.
