2. Stars, be there millions or billions of years old, are all born in nebulae--clouds of dust and mostlyhydrogen, gas. Nebulae n.星云(nebula的复数) nebulae--clouds of dust and mostly hydrogen, gas. 星云:(官方定义)是稀薄的气体或尘埃构成的天体之一。包含了除行星和彗星外的几乎所有延展型天体。
Stars are formed innebulae, interstellar clouds of dust and gas (mostly hydrogen). These stellar nurseries are abundant in the arms of spiral galaxies. An accretion disk In these stellar nurseries, dense parts of these clouds undergogravitational collapseand compress to form a rotating gas globule....

Stars are amazing and full of surprises! They’re more than just dots of light in the night sky, they tell us stories about the universe. Here are ten super cool more »
What are the corresponding steps in the text describing the process of star formation and evolution?C a. Some nebulae might become black holes. b. Stars form from rotating nebula e. c. Stars create some elements. d. New stars born after nuclear fusion. e. Supernovae spread particles for ...
In addition, the team discovered a massive cavity, spanning roughly 1,000 light-years, within the dust-dominated regions. When new, massive, and short-lived stars are born en masse, their resultant consecutive supernova explosions can produce enormous “superbubbles” within the nebula...
Sun-Sized Stars Expand to Become Planetary Nebulae Any story of the life cycle of a star for kids should include an explanation of planetary nebulae, because they are some of the most striking phenomena in the universe. The term planetary nebula is a misnomer, because it has nothing to do ...
Star formation happens in clouds of interstellar gas and dust called “nebulae”. These clouds are mostly molecular hydrogen, and are often referred to as HII regions. The process begins when the cloud is nudged into a spinning motion, perhaps by a shock wave from a nearby supernova explosion...
