The apex of the Sun's way, or the solar apex, is the direction that the Sun travels through space in the Milky Way. The general direction of the Sun's Galactic motion is towards the star Vega near the constellation of Hercules , at an angle of roughly 60 sky degrees to the direction of the Galactic Center.
center – the study of the central region of the Milky Way; disk – the study of the Milky Way disk (the plane upon which most galactic objects are aligned) evolution – the evolution of the Milky Way; formation – the formation of the Milky Way; fundamental parameters – the fundamental parameters of the Milky Way (mass, size etc.)
The Milky Way and Andromeda complete their merger into a giant elliptical galaxy called Milkomeda or Milkdromeda [11] 500 gal The Universe's expansion causes all galaxies beyond the Milky Way's Local Group to disappear beyond the cosmic light horizon, removing them from the observable universe [12] 2000 gal
Astronomers using the Gaia space telescope have located two ancient streams of stars that helped the Milky Way galaxy grow and evolve more than 12 billion years ago.

The Sun is part of one of the Milky Way's outer spiral arms, known as the Orion–Cygnus Arm or Local Spur. [270] [271] It is a member of the thin disk population of stars orbiting close to the galactic plane. [272] Its speed around the center of the Milky Way is about 220 km/s, so that it completes one revolution every 240 million years. [269]

As the Earth is located within the dusty outer arms, there are large portions of the Milky Way that are obscured from view. [66]: 837–842, 944 In the center of the Milky Way is the core, a bar-shaped bulge with what is believed to be a supermassive black hole at its center. This is surrounded by four primary arms that spiral from the core.
