In the book The Life and Death of Planet Earth, authors Peter D. Ward and Donald Brownlee state that some animal life may be able to survive in the oceans. Eventually, however, all multicellular life will die out. [81] The first sea animals to go extinct will be large fish, followed by small fish and then, finally, invertebrates. [78]
The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.
The book discusses Earth's future and eventual demise as it is ultimately destroyed by a warming and expanding Sun.The Earth's lifespan is compared to that of a living being, pointing out that the systems which keep it habitable will gradually break down one by one, like the organs in an aging human body.
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.
First, the bad news: In a little under 8 billion years, the expanding red-giant-Sun will engulf the Earth. Things gets worse from there, as you can imagine. Not that it was great to start with ...
Phobos gets closer to Mars by about 2 cm per year, and it is predicted that within 30 to 50 million years it will either collide with the planet or break up into a planetary ring. [19] Outside the Solar System, exomoons might collide with planets, removing life from them.
A total of five planets are going retrograde between May and September: Mercury, Saturn, Uranus, Neptune and Pluto. "Retrograde" is a term used to describe when a planet's orbit appears to slow.
8 × 10 11 (800 billion) years from now, the luminosities of the different galaxies, approximately similar until then to the current ones thanks to the increasing luminosity of the remaining stars as they age, will start to decrease, as the less massive red dwarf stars begin to die as white dwarfs. [26] An illustration of the local group of ...
