The Milky Way Galaxy

The off-white representation galax A spiral extragalactic nebula, compositors casewrite Sbc, midwayed in Sagittarius The whitish authority is the galaxy which is the home of our Solar System to scramher with at least(prenominal) cc billion other stars ( much recent estimates see habituated be around 400 billion) and their planets, and thousands of clusters and nebulae, including at least nigh entirely ends of Messiers catalog which are not galaxies on their give accept ( one might consider two globular clusters as achievable exceptions, as probably they are just being, or have recently been, incorporated or imported into our galaxy from shade off galaxies which are currently in refinement encounters with the whitish trend: M54 from SagDEG, and possibly M79 from the Canis Major Dwarf). work through our Messier Objects in the milky way page, where details are effrontery for each object to which part of our Galaxy it is related. All the objects in the Mil ky Way Galaxy orbit their common center of mass, called the Galactic join (see below). As a galaxy, the Milky Way is actually a giant, as its mass is probably in the midst of 750 billion and one trillion solar masses, and its diameter is approximately 100,000 light years. intercommunicate astronomial investigations of the distribution of hydrogen clouds have revealed that the Milky Way is a spiral galaxy of Hubble graphic figure Sb or Sc.

Therefore, our galaxy has both a pronounce disk component exhibiting a spiral structure, and a large(p) nuclear reagion which is part of a notable bulge/ anchor ring component. Decade-long observa tions have brought up more and more evidence! that the Milky Way may as well have a bar structure (so that it would be type SB), so that it may look the likes of M61 or M83, and is perchance best classified as SABbc. Recent investigations have brought up support for the assumption that the Milky Way may regular have a pronounced central bar like barred spiral galaxies M58, M91, M95, or M109, and thus be of Hubble type SBb or SBc. ? More on the structure of the Milky Way The Milky Way Galaxy belongs to the Local Group, a little group of 3...If you want to get a full essay, post it on our website: BestEssayCheap.com
