Explain how a star is formed. Star formation: Star formation is how the dense molecular cloud regions in the interstellar spaces, also known as a stellar nursery or star-forming region, collapse and form stars. Star formation involves the following stages; giant molecular cloud phase, protostar,...

As a result, unlike massive stars, they don't have much weight to support, and they do not have to burn through their hydrogen fuel very quickly. They are what a hybrid car is to a Hummer. They're light and very efficient at using their source of energy. This means their hydrogen ...
According to the solar nebula theory, the sun formed around 4.5 billion years ago from a massive cloud of gas and dust in space [source: NASA]. Imagine a huge cloud in space that shrinks and spins because of outside forces. This cloud becomes a flat, spinning disk, called a solar nebul...

their rarity and short lives, along with their more extreme properties, mean that the evolution of massive stars is riddled with many uncertainties. These uncertainties are compounded by the fact that accurate modeling of stellar lives in three dimensions is prohibitively expensi...
At the centre of the Southern Ring Nebula is a hot, dense white dwarf star. As it transformed into a white dwarf, the star periodically ejected mass – the shells of material you see here. ©NASA/ESA/CSA/STScI Much of the heat that was generated in the core throughout the Sun’s...

is rather inaccurate. Not only are atoms formed from smaller particles (protons and neutrons, which in turn are formed from quarks, and electrons), but they can also very much be split. Indeed, "splitting the atom" is a common phrase referring tonuclear fissionpower, and scarily the atomic...
The Webb image of the Carina Nebula, an interstellar gas cloud 7,600 light-years away, reveals the processes of star formation, stellar nurseries, and individual stars that were previously obscured, as well as a landscape of “cosmic cliffs” and valleys that showcase the Webb...
