Artist's concept of the Earth 5–7.5 billion years from now, when the Sun has become a red giant. While the future cannot be predicted with certainty, present understanding in various scientific fields allows for the prediction of some far-future events, if only in the broadest outline.

Jan 16, 2003 · At noon – after 12 billion years – the ever-expanding sun, transformed into a red giant, will engulf the planet, melting away any evidence it ever existed and sending molecules and atoms that once were Earth floating off into space.

By that point, all life on Earth will be extinct. [15][16] Finally, the planet will likely be absorbed by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet's current orbit. [17]

Oct 17, 2024 · The story of Earth is a fascinating journey through time, spanning billions of years and filled with dramatic transformations. From the fiery beginnings of our planet to the lush, diverse world we know today, Earth's timeline is a testament to the power of natural forces and the resilience of life.

Aug 21, 2019 · A history-of-Earth timeline includes everything from the birth of the sun and solar system to present-day earthquakes in California. Changes over the past 4.6 billion years were usually slow and incremental, but also sometimes violent and unforeseen, like giant meteorite strikes. Change is constant.

Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. [4][5][6] Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.

Scientists suggest that in about 7.5 billion years, the sun will use up its hydrogen and switch to helium, which will turn it into an even bigger ball of hot gas. It will burn up both Mars and Earth, notes NBC MACH.

Dec 22, 2024 · 2.7 billion years ago: Cyanobacteria become the first oxygen producers. Blue-green algae called cyanobacteria develop oxygenic photosynthesis. They use sunlight to convert carbon dioxide and...

Oct 31, 2024 · But that’s not how life on Earth used to be. With an environment devoid of oxygen and high in methane, for much of its history Earth would not have been a welcoming place for animals. The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old.

7.59 billion The Earth and Moon will probably be fall into the Sun just before the Sun reaches the tip of its red giant phase and its maximum radius of 256 times the size it has today.
