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 ...

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

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

For decades, scientists have struggled to see the outermost layer of the Sun, called the corona, with enough detail to unlock ...

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.

This helps to model the different layers of the solar atmosphere. Comparing these three different but complementary methods of observing the sun should allow solar scientists to map the flow of ...

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

The Cat's Eye Nebula, also known as NGC6543, formed when an aging sun-like star cast its outer layers into space, forming a dense central cocoon of dust surrounded by a diffuse veil of stellar ...

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 ...

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.
