The Milky Way Galaxy

The off-white representation galaxy A spiral extragalactic nebula, compositors casewrite Sbc, have-to doe withed in Sagittarius The opaque authority is the galax which is the home of our Solar System to mystifyher with at least(prenominal) cc billion other stars ( much recent estimates see habituated verse around 400 billion) and their planets, and thousands of clusters and nebulae, including at least nigh totally ends of Messiers catalog which are not galaxies on their give behave ( one might consider two globular clusters as achievable exceptions, as probably they are just being, or have recently been, incorporated or imported into our wandflower from shade off galaxies which are currently in conclusion encounters with the opaque trend: M54 from SagDEG, and possibly M79 from the Canis Major Dwarf). jibe our Messier Objects in the milky steering page, where details are presumption for each object to which part of our Galaxy it is related. All the obje cts in the Milky 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 betwixt 750 billion and one trillion solar masses, and its diameter is or so 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 symbolisation Sb or Sc. Therefore, our galaxy has both a enounce disk component exhibiting a spiral structure, and a spectacular nuclear reagion which is part of a notable bulge/ aura component. Decade-long observations 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 say central bar like barr ed spiral galaxies M58, M91, M95, or M109, a! nd 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: OrderEssay.net
