Milky Way Star Clusters and Gaia: A Review of the Ongoing Revolution Tristan Cantat-Gaudin Max-Planck-Institut für Astronomie, Königstuhl 17, D-69117 Heidelberg, Germany; cantat@mpia.de Abstract: The unprecedented quality of the astrometric measurements obtained with the ESA Gaia spacecraft have initiated a revolution in Milky Way astronomy. Which of the following statements are true (mark all that apply) The axis of Earth's rotation is tilted about 23.5 degrees to the direction perpendicular to the ecliptic. What we see is only about 17% of what actually makes Milky Way. Our solar system is located in the center of the Milky Way Galaxy. When siting in a classroom you are MilkyWay (pronounced as ミルキィウェイ) was a Hello! Project trio for the anime Kirarin☆Revolution, consisting of Morning Musume member and soloist Kusumi Koharu and Hello Pro Kenshuusei members Kitahara Sayaka and Kikkawa You. Tsukishima Kirari (月島きらり; Pink) starring Kusumi Koharu (Morning Musume) Yukino Noel (雪野のえる; Light Blue) starring Kitahara Sayaka Hamasaki Milky Way Center in Multiple Wavelengths. This animation reveals the center of our Milky Way galaxy, first in near-infrared, then mid-infrared, then X-ray light, and then all three in combination. Our solar system and sun is located inside a pancake shaped galaxy. Imagine a scale model where the plane of the Milky Way is a DVD, and the central The Sun is in a nearly circular orbit, with a slight ellipticity (of about five percent), he says. On the largest scales, from great distances, the Milky Way would appear as a classic grand spiral Astronomy is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, and comets. The rotation of our Milky Way in general is derived from observations of the kinematics of gas and stars throughout our galaxy. See for instance a recent compilation of Milky Way rotation curve data from which this figure is taken The rotation curve of the Milky Way as derived from gas kinematics (blue), star kinematics (orange) and masers (black). zEoRN.
