THE LIFE OF AN ASTRONOMER IN SPACE article
Answers
Answer:
Explanation:
Throughout History humans have looked to the sky to navigate the vast oceans, to decide when to plant their crops and to answer questions of where we came from and how we got here. It is a discipline that opens our eyes, gives context to our place in the Universe and that can reshape how we see the world. When Copernicus claimed that Earth was not the centre of the Universe, it triggered a revolution. A revolution through which religion, science, and society had to adapt to this new world view.
Astronomy has always had a significant impact on our world view. Early cultures identified celestial objects with the gods and took their movements across the sky as prophecies of what was to come. We would now call this astrology, far removed from the hard facts and expensive instruments of today’s astronomy, but there are still hints of this history in modern astronomy. Take, for example, the names of the constellations: Andromeda, the chained maiden of Greek mythology, or Perseus, the demi-god who saved her.
Now, as our understanding of the world progresses, we find ourselves and our view of the world even more entwined with the stars. The discovery that the basic elements that we find in stars, and the gas and dust around them, are the same elements that make up our bodies has further deepened the connection between us and the cosmos. This connection touches our lives, and the awe it inspires is perhaps the reason that the beautiful images astronomy provides us with are so popular in today’s culture.
There are still many unanswered questions in astronomy. Current research is struggling to understand questions like: “How old are we?”, “What is the fate of the Universe?” and possibly the most interesting: “How unique is the Universe, and could a slightly different Universe ever have supported life?” But astronomy is also breaking new records every day, establishing the furthest distances, most massive objects, highest temperatures and most violent explosions.
Pursuing these questions is a fundamental part of being human, yet in today's world it has become increasingly important to be able to justify the pursuit of the answers. The difficulties in describing the importance of astronomy, and fundamental research in general, are well summarized by the following quote:
Answer:
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, moons, comets and galaxies – in either observational (by analyzing the data) or theoretical astronomy.
Astronomy’s contributions to society have only grown more important in the thousands of years since then. The digital camera in your DSLR and smartphone — the devices fueling the rise of social media — likely wouldn’t be what they are today without decades spent by astronomers pushing their limits. Wi-fi was invented by an astronomer trying to sharpen images from his telescope. Even our ideas about the future of Earth were shaped by astronomers’ observations of the runaway global greenhouse effect on Venus — and what it meant for climate change on our own planet.
