By 3.5 billion years from now, Earth's surface conditions will be similar to those of Venus today. [117] Relative size of the Sun as it is now (inset) compared to its estimated future size as a red giant. Around 5.4 billion years from now, the core of the Sun will become hot enough to trigger hydrogen fusion in its surrounding shell. [118]
1979 – Voyager 1 flies by Jupiter and discovers its faint ring system, as well as volcanoes on Io, the innermost of its Galilean moons. [201] 1979 – Voyager 2 flies by Jupiter and discovers evidence of an ocean under the surface of its moon Europa. [202] 1980 – Voyager 1 flies by Saturn and takes the first images of Titan. [203]
These pictures were taken from 01/06 to 02/03, 1979 ; and Voyager 1 flew from 58 million to 31 million kilometers from Jupiter during that time. The small, round, dark spots appearing in some frames are the shadows cast by the moons passing between Jupiter and the Sun, while the small, white flashes around the planet, are the moons themselves.

The timeline of the early universe outlines the formation and subsequent evolution of the Universe from the Big Bang (13.799 ± 0.021 billion years ago) [1] to the present day. An epoch is a moment in time from which nature or situations change to such a degree that it marks the beginning of a new era or age .
Estimates on when the planet’s inner core may have solidified — when iron first crystallized at the center of the planet — once ranged from 500 million to 2.5 billion years ago.
As night falls, Jupiter will rise in the east-northeast, among the stars that make up the constellation of Taurus, according to NASA. Around Dec. 14, Jupiter will be visible in the night sky ...
4.5 billion Mars reaches the same solar flux as that of the Earth when it first formed 4.5 billion years ago from today. [92] < 5 billion The Andromeda Galaxy will have fully merged with the Milky Way, forming an elliptical galaxy dubbed "Milkomeda". [95] There is also a small chance of the Solar System being ejected.
