More recently ESA's Solar Orbiter has taken regular images of the Sun to track the progress as we head towards the peak of the current solar cycle. Two recently released images from February 2021 and October 2023 show how things are really picking up as we head toward solar maximum.
The Sun formed about 4.6 billion years ago in a giant, spinning cloud of gas and dust called the solar nebula. As the nebula collapsed under its own gravity, it spun faster and flattened into a disk. Most of the nebula's material was pulled toward the center to form our Sun, which accounts for 99.8% of our solar system’s mass.
Oct 18, 2023 · Our Sun is a middle-aged star, approximately 4.6 billion years old. It formed from the gravitational collapse of a region within a large molecular cloud primarily composed of hydrogen and...
May 25, 2021 · Is it really old? Or not so much? Our Sun is 4,500,000,000 years old. That's a lot of zeroes. That’s four and a half billion.
The Sun formed about 4.6 billion years ago from the collapse of part of a giant molecular cloud that consisted mostly of hydrogen and helium and that probably gave birth to many other stars. [122] This age is estimated using computer models of stellar evolution and through nucleocosmochronology. [13]
Feb 2, 2024 · About 4.5 billion years ago, the sun began to take shape from a molecular cloud that was mainly composed of hydrogen and helium. A nearby supernova emitted a shockwave, which came in contact with the molecular cloud and energized it.
