SOLAR SYSTEM

Detailed explanation-1: -A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called “star nurseries."

Detailed explanation-2: -There are many different kinds, but stellar nebulae are the clouds that form new stars. Inside stellar nebulae, space dust, hydrogen, helium and plasma swirl around and stick together and form into large blobs. These blobs eventually collapse and the stuff inside begins to heat up.

Detailed explanation-3: -Stars are born in dense clumps of gas, dust, and other material inside diffuse emission nebulae, also frequently referred to as “stellar nurseries". Hubble’s Pillars of Creation is in this category, as is the famous Orion Nebula ⁠-which you may well have seen for yourself through binoculars or a small telescope.

Detailed explanation-4: -A planetary nebula is a region of cosmic gas and dust formed from the cast-off outer layers of a dying star. Despite their name, planetary nebulae have nothing to do with planets.

Detailed explanation-5: -Dark nebulae – or absorption nebulae – are clouds of gas and dust in space that are dense enough to obscure and block light from background stars. These vast clouds are mostly composed of molecular hydrogen. They’re often locations where material is coalescing to form new stars.
