STAR will be unavailable from December 11, 2025 at 5:30 pm (HST), until December 13, 2025 around 12:00 PM (HST) as the UH begins the transition to a new and improved Student Information Database.

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 …

Dec 4, 2025 · 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, …

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.

3 days ago · Cambridge, MA (December 9, 2025)— For two decades, astronomers have puzzled over how supermassive black holes, which are some of the brightest objects in the universe, could exist …

These large, swelling stars are known as red giants. But there are different ways a star’s life can end, and its fate depends on how massive the star is.

Apr 11, 2025 · In a very broad sense, a star is simply one of those twinkling points of light you can see in the night sky. But that’s not terribly satisfying in either lexicological or physical terms.

A star is a huge sphere of very hot, glowing gas. Stars produce their own light and energy by a process called nuclear fusion. Fusion happens when lighter elements are forced to become heavier elements. …

6 days ago · The simplest way to describe a star is that it is a great ball of fire, but it is more complicated than that. A star is a giant ball of hydrogen turning into helium through nuclear fusion.

Oct 22, 2025 · Main Sequence: The protostar continues to collapse until nuclear fusion begins in its core, leading to the formation of a stable star. This stage is known as the main sequence, where the …
