The life cycle of a star - AQA The formation and life cycle of stars
WEBLearn about and revise the life cycle of stars, main sequence stars and supernovae with GCSE Bitesize Physics.
Star formation - Wikipedia
WEBStar formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as "stellar nurseries" or "star-forming regions", collapse and form stars.
How is a star born? | Scientific American
WEB6 dec. 1999 · A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity...
Exploring the Birth of Stars - NASA Science
WEBHubble’s observations of nebulae reveal bizarre landscapes sculpted by radiation from young, exceptionally bright stars. The observations reveal the violent process of star birth that produces intense ultraviolet radiation and shock fronts.
How Are Stars Born? | Webb - WebbTelescope.org
WEB31 mei 2018 · Stars form from collapsing clouds of gas and dust. Astronomers can train telescopes on giant clouds of hydrogen gas in our own galaxy and find knots of denser, colder gas and dust that are in the process of giving rise to stars. These dust-thick regions of star birth are often dark and opaque.
Beholding the Birth and Death of Stars | HubbleSite
WEBNewborn stars are found in grouping called open clusters. Ancient stars, the galaxy’s first homesteaders, dwell in globular star clusters with populations of 1 million stars each. Hubble has helped astronomers find the birth certificate of a star that has been around for a …
Stars - NASA Science
WEBStars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements. Every star has its own life cycle, ranging from a few million to trillions of years, and its properties change as it ages.

WEBInfrared Spitzer image of a star-forming region. Credit: NASA/JPL-Caltech/ Harvard-Smithsonian CfA. To unravel the birth and early evolution of stars and planets, we need to be able to peer into the hearts of dense and dusty cloud cores where star formation begins.
Star Lifecycle - NASA Science
WEBGroups of stars make up galaxies, while planets and ultimately life arise around stars. Although stars have been the main topic of astronomy for thousands of years, we have begun to understand them in detail only in recent times through the advent of powerful telescopes and computers.
