Final answer:
Pseudoscience includes claims or practices that appear scientific but do not adhere to scientific standards like testability and peer review, such as astrology. Astronomy, in contrast, is a legitimate science based on empirical evidence and rigorous methodologies.
Step-by-step explanation:
Pseudoscience refers to any claim, belief, or practice that is presented as scientific, but fails to adhere to the scientific method and cannot be reliably tested. A notable example of pseudoscience is astrology, which purports that the positions and movements of celestial bodies have a direct impact on human affairs and natural phenomena. Despite its historical role in encouraging the study of celestial patterns, astrology lacks empirical evidence to support its claims and is therefore not considered a scientific discipline. By contrast, astronomy evolved from these early studies into a rigorous science that systematically observes, records, and defines the behavior of planets, stars, galaxies, and other celestial phenomena.
Pseudoscience may appear to be scientific but does not follow the critical standards that are fundamental to the scientific process such as peer review, reproducibility, and empirical testing. Examples include astrology, creationism, and various alternative medicine practices. Unlike these, scientific discoveries are grounded on empirical evidence and are subject to constant scrutiny and testing.
