A nebula (Latin for ‘ cloud or ‘fog’; pl. nebulae nebulæ or nebulas) is an interstellar cloud of dust hydrogen helium and other ionized gases.Originally the term was used to describe any diffused astronomical object including galaxies beyond the Milky Way.The Andromeda Galaxy for instance was once referred to as the Andromeda Nebula …

The various planets are thought to have formed from the solar nebula the disc-shaped cloud of gas and dust left over from the Sun’s formation. The currently accepted method by which the planets formed is accretion in which the planets began as dust grains in orbit around the central protostar .Through direct contact and self-organization these grains formed into clumps up to 200 m (660 ft …

The Nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems).It suggests that the Solar System formed from gas and dust orbiting the Sun.The theory was developed by Immanuel Kant and published in his Allgemeine Naturgeschichte and Theorie des Himmels (“Universal Natural History …

An open cluster is a group of up to a few thousand stars that were formed from the same giant molecular cloud and have roughly the same age. More than 1 100 open clusters have been discovered within the Milky Way Galaxy and many more are thought to exist. They are loosely bound by mutual gravitational attraction and become disrupted by close encounters with other clusters and clouds of gas as …

Protostars form from molecular clouds consisting primarily of molecular hydrogen.When a portion of a molecular cloud reaches a critical size mass or density it begins to collapse under its own gravity.As this collapsing cloud called a solar nebula becomes denser random gas motion…
