Invisible sunspots uncovered
... Sunspots appear as dark patches on the Sun's photosphere. They were first observed by Chinese astronomers and later extensively studied by Galileo with the aid of a telescope. Their temperature is of approximately 4,000 degrees, lower than that of the surrounding photosphere (6,000 degrees). The bir ...

Don`t Panic, But the Sun Will (Far) Outlive Earth (Op-Ed)

After about a billion years the sun will become hot enough to boil our oceans. The sun is currently classified as a “main sequence” star. Th ...
