Fluid dynamics simulations of a red giant, with giant convection cells and puffy surface. A red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses (M ☉)) in a late phase of stellar evolution.
UY Scuti (BD-12°5055) is a red supergiant star, located 5,900 light-years away in the constellation Scutum.It is also a pulsating variable star, with a maximum brightness of magnitude 8.29 and a minimum of magnitude 10.56, which is too dim for naked-eye visibility.
This is the nearest red giant to the Earth, and the fourth brightest star in the night sky. Pollux (β Geminorum) 9.06 ± 0.03 [95] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [101] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [102]
The red giant π1 Gruis is 530 light-years away, and it's reaching the end of its natural life. Soon, scientists think it will become a planetary nebula. But before it dies, astronomers are using ...
The images show the surface of the star R. Doradus, a red giant star 180 light-years away in the Dorado constellation. The star has a diameter about 350 times that of the sun, and it serves as a ...
This red giant star will, one day, explode as a supernova. Betelgeuse is one of the best-known stars in the night sky, as well as the easiest to find. New examinations of this behemoth star ...
HD 18438 is a red giant star in the deep northern constellation of Cepheus, located about 730 light-years (220 parsecs) from Earth.With an apparent magnitude of 5.49, it is visible by the naked eye under dark skies as a red-hued dot of light about 10 degrees away from the celestial north pole.
