Galaxy z is 13.1 billion years old, only about 700 million years younger than the universe. That was when the Moon Formed, the Moon was twice as close then it is now causing 10,000 ft. (1.5 Billion Years since the Birth of Earth) - 2.4 billion years ago, oxygen in the atmosphere suddenly increased by about 10,000 times in just 200 million years.Ocean organisms and primitive animals start to evolve.Gondwana formed prior to Pangaea, and later became part of it.Continental Drift - Earths Surface Dinosaurs go extinct.Almost all the present phyla plants (Asterids - Verbena) appeared during this period, with the exception of Bryozoa, which are a phylum of aquatic invertebrate animals who made its earliest known appearance later, in the Lower Ordovician. First land plants occurs in the Ordovician, in the form of fossil spores.Land plants began to diversify in the Late Silurian, from around 430 million years ago, and the results of their diversification are displayed in remarkable detail in an early Devonian fossil assemblage from the Rhynie chert.This chert, formed in volcanic hot springs, preserved several species of early plants in cellular detail by petrification.
With the exception of some ectothermic species like the leatherback sea turtle and crocodiles, no tetrapods weighing more than 25 kilograms (55 lb) survived.
Ions can be created, by either chemical or physical means, via ionization. Oxygen is what makes the sky blue, molecules in the air scatter blue light from the sun more than they scatter red light.
Shape of the Universe - Photo GN-z11 high-redshift galaxy found in the constellation Ursa Major, and is currently the oldest and most distant known galaxy in the observable universe - 13.4 billion years old. Mostly Molten Rock Theia collided with another planetary-mass object, Gaia (the early Earth) around 4.51 billion years ago. New type of Green Algae produced O2, which created the Ozone Layer that protected life from damaging UV Rays and gave life a chance to progress.
The Scale of the Universe from Big to Small (youtube) The Scale of the Universe from Small to Big (youtube) NASA Astronomy Picture of the Day (APOD) The Scale of the Universe - Interactive (manual control scale) Sizes (nano) Stars and Galaxies started to form.
Reionization marks the point at which the hydrogen in the Universe became ionized.
The photo above is not to make you feel insignificant, it is only for reference and scale. Depending on your field of view, you would have to be around 100,000 light years away to see this Galaxy using the naked human eye.
