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.

4 days ago · What is a star? A star is any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources. Of the tens of billions of trillions of stars in the observable universe, only a very small percentage are visible to the naked eye.

The Stress, Trauma and Resilience (STAR) Program at the Ohio State Department of Psychiatry and Behavioral Health offers programs and services in three basic areas.

Star House Columbus provides local youth experiencing homelessness with a safe respite & the crucial connections to stabilizing resources—all in one welcoming place.

May 2, 2025 · A star’s gas provides its fuel, and its mass determines how rapidly it runs through its supply, with lower-mass stars burning longer, dimmer, and cooler than very massive stars.

May 8, 2025 · How does a star work? How do they form, live, and eventually die? Learn more about these distant objects and their major importance in the universe.

Jul 15, 2014 · A star is a luminous ball of gas, mostly hydrogen and helium, held together by its own gravity. Nuclear fusion reactions in its core support the star against gravity and produce photons and heat, as well as small amounts of heavier elements.

Jan 4, 2021 · It's easy enough to say what a star is: one of those bright pointy things that twinkle in the night sky. But the actual definition of a star is as rich and colorful as the stars themselves.

The Pleiades, an open cluster of stars in the constellation of Taurus. NASA photo. A star is a massive, luminous ball of plasma that is held together by its own gravity. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth. Other stars are visible in the night sky, when they are not outshone by the Sun.

Within each system, the star sits at the centre, providing heat and light that shapes and characterises the planets and other bodies in orbit around it. That light may even be the basis for life on some of those worlds, like the Sun in our Solar System.
