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: -“a nebula is a cloud of gas and dust in outer space, visible in the night sky either as an indistinct bright patch or as a dark silhouette against other luminous matter.” Many nebulae are visible due to fluorescence caused by embedded hot stars.
Detailed explanation-3: -Nebula are often found in the space between stars, known as the interstellar medium. On average, this region contains only around one atom per cubic centimetre. However, in certain places the density can be significantly higher than this -high enough to become visible through a telescope.
