About 17 years ago, J. Martin Laming, an astrophysicist at the U.S. Naval Research Laboratory, theorized why the chemical composition of the Sun’s tenuous outermost layer differs from that lower down.

The elemental composition of the Sun’s hot atmosphere known as the ‘corona’ is strongly linked to the 11-year solar magnetic activity cycle, a team of scientists from UCL, George Mason University and ...

One crucial reason astronomers study the Sun is to gain knowledge of stars other than the Sun. This is relevant to understanding the chemical composition of stars, the structure of stars, as well as ...

After two decades of debate, scientists are getting closer to figuring out exactly what the sun — and thus the whole universe — is made of. The sun is mostly composed of hydrogen and helium. There are ...

The sun has long been a subject of mystery. What is that big yellow ball in the sky made of? If we now know, it's thanks in part to the groundbreaking work of one woman: Cecilia Payne. This ...

Our sun was born 4.6 billion years ago near the crowded center of the Milky Way and then migrated roughly 10,000 light-years ...
