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 ...
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]
2.6 billion years (11 Gya): first stars in the thick disk region of the Milky Way are formed. [11] 4 billion years (10 Gya): Gaia Enceladus merges into Milky Way. [11] 5 or 6 billion years, (8 or 9 Gya): first stars in the thin disk region of the Milky Way are formed. [11]
This photo, and many other images that have been released from Juno's extended mission, employs color enhancement to help visualize the depth between the layers of clouds in Jupiter's deep atmosphere.
This model posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years. Many stars, including the Sun, were formed within this collapsing cloud. The gas that formed the Solar System was slightly more massive than the Sun itself.

Once every 53.5 days, NASA's Juno probe screams over Jupiter's cloud, capturing stunning images in the process. NASA's $1 billion Jupiter probe just sent back dazzling new photos of the giant ...
If the disk is massive enough, the runaway accretions begin, resulting in the rapid—100,000 to 300,000 years—formation of Moon- to Mars-sized planetary embryos. Near the star, the planetary embryos go through a stage of violent mergers, producing a few terrestrial planets. The last stage takes approximately 100 million to a billion years. [2]
