Even if Earth does survive, it won’t be pretty. The temperature of our planet will be about 1,300 degrees C, hot enough to ...

How far away it is: 93 million miles (150 million km) ...

The Sun, our life-giving star, is slowly dying. In about 5 billion years, it will exhaust its fuel and transform into a red giant, altering the solar system forever. But long before that, the Sun’s ...

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.

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 ...

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 ...

Very massive stars are cosmic "rock stars" that live fast, die young and leave black holes in their place. During this ...

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.
