Curtis' spiral nebulae. It is not so well known that in 1920 Curtis' plot of the period-luminosity relation suggests that he didn't believe it was a physical relation and also he failed to appreciate the significance of the Russell diagram for understanding the large size of the Milky Way....
Solar system, assemblage consisting of the Sun and those bodies orbiting it: 8 planets with about 210 known planetary satellites; many asteroids, some with their own satellites; comets and other icy bodies; and vast reaches of highly tenuous gas and dust

Hertzsprung-Russell diagram, in astronomy, graph in which the absolute magnitudes (intrinsic brightness) of stars are plotted against their spectral types (temperatures). The Sun lies near the middle of the main sequence on the diagram. Learn more about
The full moon occurs halfway through the cycle when its position is exactly opposite to that of its position during a new moon. When the moon is moving from new to full, it is known as waxing. From Earth, we see the brightness of the moon increase as we see more and more of the ...

MILKY WAY SATELLITESCOLOR - MAGNITUDE DIAGRAMThe Milky Way satellites offer the possibility of studying their star formation histories in great detail. Color - magnitude diagrams (CMDs) reaching the old main - sequence turnoffs, allow a careful modelling of their stellar populations using synthetic ...
Context. The study of the Milky Way is living a golden era thanks to the enormous high-quality datasets delivered by Gaia, and space asteroseismic and ground-based spectroscopic surveys. However, the current major challenge to reconstructing the chronology of the Milky...
