Cosmic Queries: A StarTalk Guide for Humanity

From the Publisher: Naked Eye Astronomy

Astronomy developed without the aid of telescopes. Even without these powerful instruments, ancient astronomers were able to achieve a remarkable list of accomplishments. They accurately measured the position of prominent stars, determined the distance from Earth to the Moon, discovered the precession of the equinoxes (a subtle wobble in Earth's axis of rotation), and developed sophisticated models of the solar system.

How Did the Universe Get To Be This Way?

A supercomputer in Germany was used to generate three-dimensional simulations of dark matter in the universe. The resulting images provide valuable insights into the formation and structure of the cosmos.

How Did Life Begin?

Meteorites found in Antarctica may hold clues about the origins of life on Earth and beyond. These frigid rocks, which are among the least contaminated examples of comet and asteroid fragments, offer a unique window into the early conditions that gave rise to life.

Are We Alone in the Universe?

Images taken by NASA's Mars Reconnaissance Orbiter show features on the surface of Mars, such as caverns and rivulets, that suggest the possible presence of water and, perhaps, life in the distant past.

How Did It All Begin?

A massive computer simulation centered on a supercluster of galaxies reveals the intricate, filamentary large-scale structure of the universe, providing insights into its origins and evolution.

How Will It All End?

The serene northern lights gently loom over ice cracks in Alberta's Abraham Lake, evoking the eventual fate of the universe: a gradual descent into ice and darkness.
