This will cause the outer layers of the Sun to expand dramatically, transforming it into a "red giant." During this phase, the Sun will swell to immense proportions, engulfing Mercury and Venus.

For example, a calculation that modifies the effectiveness of convective heat transfer, which influences only the very outer layers of the Sun, yields W ≈ 0.002 (refs 5,6), whereas studies that ...

A STRONOMERS are accustomed to divide the outer regions of the sun into four parts: (1) the photospheric layers, (2) the reversing layer, (3) the chromosphere, (4) the corona. In this address I ...

An international team, led by Instituto de Astrofísica e Ciências do Espaço (IA) researcher Ângela Santos, has made the first ...

The outer layers that swell during the red-giant phase will become a shell of gas called a surrounding planetary nebula. This shell will be shed after approximately 1 billion years.
