Astronomers call stars that are stably undergoing nuclear fusion of hydrogen into helium main sequence star s. This is the longest phase of a star’s life. The star’s luminosity, size, and temperature will slowly change over millions or billions of years during this phase. Our Sun is roughly midway through its main sequence stage.
Stars 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.
Building Our Knowledge of How Stars and Planets Begin Our current understanding of how, when, and where stars and planets form and evolve is advanced through theory and observation. Data from current and next-generation telescopes will inform new computational models for stellar and planetary life cycles.

Many other stars are visible to the naked eye at night; their immense distances from Earth make them appear as fixed points of light. The most prominent stars have been categorised into constellations and asterisms, and many of the brightest stars have proper names.
This article describes the properties and evolution of individual stars. Included in the discussion are the sizes, energetics, temperatures, masses, and chemical compositions of stars.
The star originates from the Large Magellanic Cloud and probably formed directly after the first stars through dust cooling.
Stars are massive, luminous spheres of gas, mainly composed of hydrogen, with smaller amounts of helium and other elements. The lifespan of a star varies widely, generally ranging from several million to several trillion years.
How are stars named? And what happens when they die? These star facts explain the science of the night sky.
Stars are luminous spheres made of plasma – a superheated gas threaded with a magnetic field. They are made mostly of hydrogen, which stars fuse in their cores. That process releases energy, which pushes against the weight of the outer layers of the star and keeps it stable.
A star is a luminous spheroid of plasma held together by self-gravity. [1] The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night; their immense distances from Earth make them appear as fixed points of light. The most prominent stars have been categorised into constellations and asterisms, and many of the brightest stars have proper names. Astronomers have ...
Star, any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources. This article describes the properties and evolution of individual stars. Included in the discussion are the sizes, energetics, temperatures, masses, and chemical compositions of stars.
Stars Stars are massive, luminous spheres of gas, mainly composed of hydrogen, with smaller amounts of helium and other elements. The lifespan of a star varies widely, generally ranging from several million to several trillion years. According to NASA, astronomers estimate there could be as many as one septillion stars in the universe, which is a one with 24 zeros after it. Within our galaxy ...
Types of Stars Astronomers sort stars into categories according to their spectral characteristics – that is the information contained in the light they radiate. The general categories are O, B, A, F, G, K, M, R, N, T, Y, and group stars (and stellar objects) by their temperatures, luminosities, and colors.
What are stars, how do they form and die? Our guide packed with facts about stars and answers to some of the most commonly-asked questions.
