Earth orbits one of the hundreds of billions of stars in our galaxy, which in turn is one of hundreds of billions in the observable universe. This apparent insignificance fits with the Copernican principle that our planet is not the center of the cosmos but simply a mediocre member of a mediocre solar system.

Why is the sun so important to US on Earth?
Nothing is more important to us on Earth than the Sun. Without the Sun’s heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
What are the benefits of space exploration?
The benefits of space can be categorized as either direct or indirect. The direct benefits of exploration include the generation of scientific knowledge, the diffusion of innovation and creation of markets, the inspiration of people around the world, and agreements forged between the countries engaged in exploration.
Why is it important to study life on other planets?
“Just having another example of life anywhere would be amazing,” Schaefer said. It would also help to illuminate what happened on Earth during the billions of years before oxygen became abundant and, through processes and feedback loops that remain opaque, complex life burst forth.
Is Earth a good archive for evidence of life on other planets?
Earth’s very liveliness makes it a poor archive for evidence of life and its impacts. Other planetary bodies – some of them dead still and bone dry, others somehow akin to the ancient Earth – may prove better suited to the task.
