Q

Evidance about big bang theory

A

Cosmic Microwave Background, galaxies moving away (redshift), expected and seen light element amounts, and the universe’s structure all suggest a hot beginning and expansion.

21
Q

Hazards of space

A

Space travel hazards include radiation exposure, microgravity effects on the body, psychological challenges, spacecraft malfunctions, and the risk of collisions with debris.

22
Q

Benefits of space travel

A

Space travel brings technological innovation, scientific discoveries, economic growth, global collaboration, and inspires human potential.

23
Q

different techniques
astronomers use to search for possible
habitable planets.

A

Astronomers use methods like transit, radial velocity, direct imaging, and astrometry to search for habitable planets by detecting star and planetary characteristics.

24
Q

Describe how astronomers use
telescopes

A

Telescopes enable astronomers to observe and study distant celestial objects by collecting and magnifying light.

25
What are 2 telescopes
Two types of telescopes are refracting telescopes, which use lenses to bend and focus light, and reflecting telescopes, employing mirrors to gather and direct light for observation.
26
Describe how a Convex lens works
A convex lens bends light inwards, focusing it to a point, which magnifies and sharpens images.
27
Describe how astronomers search for life on other planets. Include SETI and Carl Sagan!
Astronomers, inspired by Carl Sagan, search for alien life using methods like SETI, scanning for signals, and exploring planets, such as Mars, for signs of microbial existence.
