FAQ
Frequently Asked Questions
Yes, but only during the brief moments of a total solar eclipse, when the Moon completely blocks the brighter photosphere, revealing the faint, reddish chromosphere.
The name comes from the Greek words 'chroma' (colour) and 'sphaira' (sphere). It was named for its reddish colour, which is primarily due to the emission of hydrogen-alpha light.
No, many stars, particularly those similar to the Sun, have chromospheres. The study of stellar chromospheres helps astronomers understand stellar activity and magnetic fields.
Temperatures range from about 6,000 Kelvin at the bottom (near the photosphere) to between 20,000 and 50,000 Kelvin at the top (transitioning to the corona), which is paradoxically hotter than the solar surface below.
The second of the three main layers of the Sun's atmosphere, located between the photosphere and the corona, characterized by a reddish glow visible during total solar eclipses.

Mnemonic
Think of a CHROMatograph (showing colours) and a SPHERE. The 'colour-sphere' is the reddish-pink layer seen around the Sun during an eclipse.
Conceptual Metaphor
The Sun's skin or outer veil that reveals its true, fiery colours.
