We are here.
Our Sun is one of the billion of stars in our galaxy, the Milky Way. It is located about 26,000 light- years from the centre of the galaxy. The Milky Way is a large spiral galaxy in the form of a dusk, and is about 100,000 light years.
By the way, the universe is about 93 billion light-years across!
A light-year (symbol: ly) is a unit of distance; it is the distance that light travels in one year. Light moves at a velocity of about 300,00 km/s. That is fast and nothing can travel faster.
OVERVIEW OF THE SOLAR SYSTEM
Our Solar System condensed from a slowly rotating cloud of gas and interstellar dust about 4.6 billion years ago. The gas cloud or solar nebula was primarily made up of Hydrogen and Helium, with much smaller amounts of heavier elements like Carbon, Nitrogen, Silicon, Sulphur, Iron and others.
Our Solar System is about 4 light-years in diameter and one object makes it special. It has a planet that supports life; Earth.
In the April 2012 issue Proceedings of the National Academy of Sciences of the United States of America (PNAS), scientists announced that Life began on Land (in ponds) and not in Sea!
The lead scientist Prof. Mulkidjanian from University of Osnabruck said ”the ocean was invaded by life at a later stage”
Anyway, land or sea, life somehow began and it is beautiful.
