Gravitacional Tides on Black Holes


 

The Earth’s habitable zone, defined as the region around the Sun where water could be found in liquid form. Therefore, if there is a planet suitable for supporting life (as we know based on our definition of life), it must reside within the habitable zone of its star. The Earth is in the habitable zone of the Sun.


 

Schematic picture showing the increase in the size of a low-mass star as a result of fuel burning at the core and shifting of the hydrogen- and helium-burning layers to larger radii. Eventually, the outer envelope of the star is ejected, forming a planetary nebula. Different colors in the planetary nebula indicate sites of different chemical elements.
