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.
Measurements with the Hubble Space Telescope in 2006 suggest the Magellanic Clouds may be moving too fast to be orbiting the Milky Way. [3] Of the galaxies confirmed to be in orbit, the largest is the Sagittarius Dwarf Spheroidal Galaxy, which has a diameter of 2.6 kiloparsecs (8,500 ly) [4] or roughly a twentieth that of the Milky Way.
Three of the closest dwarf irregular satellites of the Milky Way include the Small Magellanic Cloud, Canis Major Dwarf, and the newly discovered Antlia 2. The Large Magellanic Cloud, the Milky Way's largest satellite galaxy, and fourth largest in the Local Group. This satellite is also classified as a transition type between a dwarf spiral and ...
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 best dates to see the Milky Way are June 28 to July 8, July 28 to Aug. 7, Aug. 26 to Sep. 6 and Sep. 24 to Oct. 5. ... Go beyond the basic sandwich this year — Here are our most popular ...
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.
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.)
