Like all stars, Betelgeuse emits light because it is very hot. The heat for that light comes from nuclear fusion reactions occurring in the star. Unlike in most other stars, the fusion is occurring in a shell around the core rather than in the core itself.
Betelgeuse is approximately 600 light years from Earth.
Betelgeuse is about 640 light-years from the sun.
The red color of Betelgeuse is due to its relatively low surface temperature compared to other stars, causing it to emit more red and orange light. This cooler temperature indicates that Betelgeuse is nearing the end of its life cycle and will eventually explode as a supernova.
Betelgeuse is a red supergiant in the constellation Orion. It is approximately 640 light years from us.
Betelgeuse is approximately 430 light years away from Earth, while Capella is about 42.9 light years away. Therefore, Betelgeuse is around 387.1 light years farther away from Capella.
Betelgeuse is approximately 642.5 light years away from Earth.
Betelgeuse is one of the prominent stars in the Constellation of Orion.It is actually ORANGE-RED in color.It belongs to the spectral class K ( with temperature 4,900 - 3,500 degrees Kelvin )Betelgeuse is a semiregular variable star located approximately 640 light years from the Earth.It has a spectral type of M2 and a temperature of about 3,500K which means it has a colour of red.

Technetium doesn't emit light.
The surface of Betelgeuse emits light across a broad range of wavelengths, including visible, infrared, and ultraviolet light. The dominant wavelength emitted by Betelgeuse is in the red region of the spectrum, specifically around 700 nanometers.
The Earth does not emit light, it like the moon reflects light
