Tag: how scientists detect nebula

[ad_1] Nebula is nothing but the beginning of a star! How? NASA explains that Nebulae are composed of dust and gaseous matter, primarily hydrogen and helium. Despite being dispersed, gravity can cause clumps of dust and gas to converge over time, leading to increased gravitational pull. Once these clumps become substantial, they collapse under their own gravity, heating up the central material and forming the beginnings of a star.Today's NASA's Astronomy Picture of the Day is NGC 2626, a beautiful, bright, blue reflection nebula in the southern Milky Way which is centered in this colourful cosmic canvas. NGC 2626 is located near a dusty cloud and encircled by reddish hydrogen emissions from the H II region RCW 27. It is part of a group of dusty molecular clouds called the Vela Molecula...
