What is space in astronomy?
In astronomy and cosmology, space is the vast 3-dimensional region that begins where the earth’s atmosphere ends. Space is usually thought to begin at the lowest altitude at which satellites can maintain orbits for a reasonable time without falling into the atmosphere.
What is astronomy subject?
Astronomy is the study of everything in the universe beyond Earth’s atmosphere. That includes objects we can see with our naked eyes, like the Sun , the Moon , the planets, and the stars . It also includes objects we can only see with telescopes or other instruments, like faraway galaxies and tiny particles.
What does space mean in physics?
space, a boundless, three-dimensional extent in which objects and events occur and have relative position and direction.
Astronomy is among the oldest of sciences. Physics and astronomy became even more closely joined as discoveries in atomic physics opened the path to understanding the true nature of the stars, and the development of nuclear physics finally made it possible to understand how they shine for so long.
Who unified physics and astronomy?
Sir Isaac Newton
Sir Isaac Newton and the Unification of Physics & Astronomy. Sir Isaac Newton (1642-1727) was by many standards the most important figure in the development of modern science.

What are some good space research topics for a paper?
Research topics about space are relatively easy to find considering the broad research areas, which include: Earth observations, Geodesy, Atmospheric Sciences, Space physics, Planetology, Astronomy, Materials sciences, Life sciences, and Physics. Space research paper topics must stimulate and birth inquiry and answer compelling questions.
What is astronomy about?
As a result, the topic of astronomy deals with all that which extends beyond the context of which is most familiar to humans. While advances in telescopes, satellites and space travel have allowed humans to peer beyond the Earth, the degree to which this has occurred barely touches the surface of the vastness that is outer space.
