Earth's birth secret is out: Dwarf galaxy Leoncino reveals condition of space during the Big Bang

This might be it, friends. The long-awaited answer to the question - how was Earth born.

Earth's birth secrets have amused astronomers for ages. They might have finally cracked the case.

Astronomers from Indiana University, USA, have found a 'low-metal' galaxy nicknamed Leoncino or the 'little lion' that can be observed to find out the answer.

The low metal quantity in the galaxy indicates towards the conditions during the Big Bang that apparently gave birth to our Solar System.

Here are the key points you must know:

• Leoncino is a galaxy that has the lowest level of heavy chemical elements or 'metals' ever observed in a system of stars
• There are only a few ways to determine the conditions through which the universe was born. Exploring low-metal galaxies is the most promising method among all
• Our galaxy is younger in comparison to other distant galaxies. It contains a large amount of heavy chemical elements, which makes it a poor source to find answers
• In order to find out such answers, astronomers must look far from our Solar System and observe dying galaxies and calculate the ratio of helium and hydrogen
• The ratio of these two gases indicate towards the conditions that prevailed during the Big Bang
• Leoncino is a relatively smaller galaxy. Its diametre is around 1,000 light years and it contains only a few million stars. Hence, it is called a dwarf galaxy
• Leoncino is within the bounds of 'local universe', which is a region of space within 1 billion light years from Earth. The local universe contains several million galaxies.
