The spectrum of light emitted by a star also reveals information about its chemical composition, as different elements emit light at different wavelengths. By studying the colors of stars, astronomers can learn about the physical conditions in their atmospheres and interiors, and understand more about the universe as a whole.

In between these two extremes are stars that are yellow, like our own Sun. The color of a star can also change over time as it ages and evolves. For example, a star may start off hot and blue, and then gradually cool and become redder as it evolves.

Hotter stars have temperatures of tens of thousands of kelvins and emit more blue and ultraviolet light. These stars appear blue or blue-white. On the other hand, cooler stars have temperatures of just a few thousand kelvins and emit more red and infrared light. These stars appear red or orange.

The color of a star is determined by its surface temperature. Stars are made up of hot gases, and the temperature of these gases determines what color the star appears to be. The temperature of a star is determined by its mass, age, and stage in its lifecycle.

Came across a thread on Twitter that asked the question “Why do stars have different colors?”

To answer simply: The color of a star is determined by its temperature. Hotter stars emit more blue light, while cooler ones give off red & orange hues. This is due to the way that different elements in a star's atmosphere emit light.

Have you ever wondered why the sunset on appears bluish? It's all because of the fine dust particles in the atmosphere. These particles scatter sunlight in a similar way to how 's atmosphere scatters sunlight to create a blue sky.

The Wow! signal was a strong radio signal detected by the Big Ear radio telescope in 1977 that some people believe may have been transmitted by extraterrestrial intelligence. However, the signal has not been detected again and the source of the signal remains unknown.
