Astrophysics vs Astrobiology: Everything You Need to Know

In 1835, a well known French philosopher, Auguste Comte, stated that humans would never be able to understand the real nature of the stars, i.e. their chemical composition.
But he was soon proved wrong, because luckily, in the latter half of the 19th century, there was a sort of revolution in the astronomy field.
Astronomers began to make use of two new techniques—spectroscopy and photography.
We can say that was likely the birth of Astrophysics.
Together, spectroscopy and photography helped bring a new understanding of the cosmos, and for the first time, scientists could investigate what the universe was made of. They could understand how the Sun was burning, and what the Sun was burning.
This was a major turning point in the development of a newly born science: cosmology.
Astronomers were able to record and document not only where the stars were but what they were as well.
But what’ s spectroscopy? And what’s exactly astrophysics?

What is Astrobiology?

Humans spent thousands of years gazing at the night sky and wondering about the presence of life elsewhere.
Could it be in our solar system? Could it be on some other blue planet around another star? Nobody ever knew. But such thoughts have found their expression in fiction, scientific missions and religions worldwide.
Pondering the rise of life on our planet was not only a philosopher’s but also an ordinary people job.
Creation myths have been fundamental to every civilization and culture and reflected the profound resonance of the question of our origins.

What about today? Did we make some steps forward?

Today, astronomers have pushed back our understanding of the origins of the universe to tiny tiny fractions of microseconds of the big bang.
However, we can’t yet give any satisfying definition of life, nor yet point to the exact time and conditions when the organic matter first went from unanimated to animated, from nonliving to living.
It was about 50 years ago when humanity began to extend its presence into space, first with robots and then with humans.
