The Earth Has Seen Five Major Mass Extinctions. Are We In the Sixth?| Sciencing
Stars, such as the sun, are large balls of plasma that can produce light and heat in the area around them. While these stars come in a variety of different masses and forms, they all follow the same basic seven-stage life cycle, starting as a gas cloud and ending as a star remnant.| Sciencing
The sun has been our source of energy for billions of years. While some wonder if it will eventually explode, it won't, but its death will be much slower.| Sciencing
If we ever find life on a planet orbiting a white dwarf star, it will be life that has emerged only after the red giant phase has passed and the white dwarf has emerged as a stellar relic. That’s the conclusion of a study being discussed today at the National Astronomy Meeting of Britain’s Royal Astronomical Society, which convened online due to COVID concerns. The work is also recently published in Monthly Notices of the Royal Astronomical Society.| Centauri Dreams
