How can Star Gazing be useful in everyday life?
On a more pressing level, astronomy helps us study how to prolong the survival of our species.
For example, it is critical to study the Sun’s influence on Earth’s climate and how it will affect weather, water levels etc.
Astronomy is one of the few scientific fields that interacts directly with society..
Can life exist on stars?
A shocking new study reveals the possibility of the existence of alien life within the stars. This broadens the hunt for aliens, which was once limited to planets. Researchers are suggesting that there is a “unique” form of life that evolves within a star.
What would happen without stars?
So, stars are like the furnaces which forge elements. Without them, there wouldn’t be elements other than hydrogen and helium. Hence, the universe would be very cold and dark place, bathing itself with cosmic background radiation with no life forms to be seen anywhere.
Why is studying the stars important?
It is what keeps the Earth warm enough for us to live on and it provides the light needed for plants and animals to stay healthy. (3) When we study stars, we also learn something about how they are born and die. This helps us understand how our own solar system was formed.

Why do stars shine?
Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.
What are old stars called?
About 200 million years after the Big Bang, the very first stars (called Population III stars) began to form. … These ancient stars, which are all Population II stars, are nearly as old as the universe.
Why do we observe and study stars?
Why we study stars. Once we look beyond the solar system, most of what we can learn about the Universe is based on observing stars. … Not only do they light up the sky, they produce the raw materials that make life possible, and if there is life out there, it is most likely orbiting a star on its planet.
