How do we study space?

General Study Space Tips
  1. Make sure all your study materials are functioning. Do this before you start studying.
  2. Make your study space ergonomic.
  3. Keep your study space as clean (or messy) as you like.
  4. Take breaks every 30-60 minutes.
  5. View your study space as a WIP.
  6. Make the best of the space you have.

Why do we study galaxies?

Observations of distant galaxies show us what the universe looked like at an earlier time in the history of the universe. By studying the properties of galaxies at different epochs, we can map the evolution of the universe.

What is our galaxy name?

the Milky Way

What is the study of space and time?

Cosmology is a branch of astronomy that involves the origin and evolution of the universe, from the Big Bang to today and on into the future. According to NASA, the definition of cosmology is "the scientific study of the large scale properties of the universe as a whole."

What is the role of a star?

A star is a huge glowing ball of hot gas, mainly hydrogen and helium. The temperature is so high in its core that nuclear fusion occurs, producing energy. The outward pressure of gas heated by fusion is balanced by the inward pull of gravity, leaving the star in hydrostatic equilibrium.

What is the purpose of the stars?

By convention, astronomers grouped stars into constellations and used them to track the motions of the planets and the inferred position of the Sun. The motion of the Sun against the background stars (and the horizon) was used to create calendars, which could be used to regulate agricultural practices.
