blue giant
Hot luminous star
A blue giant is a massive, extremely hot star that burns through its nuclear fuel rapidly, appearing blue-white due to its high surface temperature.
Blue giants are among the most luminous stars in the universe but have relatively short lifespans—millions rather than billions of years.
Rigel in Orion is a blue giant visible from Earth.
