Connects introductory astronomy to a broad understanding of the universe

With Astronomy Today, authors Eric Chaisson and Steve McMillan communicate their excitement about astronomy, combining up-to-date science with insightful pedagogy. The text emphasizes visualization and focuses on the process of scientific discovery in order to teach students “how we know what we know.”

The 9th Edition reflects current research and discoveries in the field of astronomy including the Horizon mission on Pluto, the Mars Maven mission on Mars, and the discovery of a potentially habitable planet around Proxima Centauri.

Hallmark features of this title

Encourage conceptual understanding

  • The Big Picture explains how a chapter's content fits into an overall perspective on introductory astronomy and how the chapter is connected to a broad understanding of the universe.
  • Concept Checks critical-thinking questions prompt students to reflect on the material presented and test their mastery of key concepts.

Develop skill building

  • Process of Science Check questions prompt students to consider how astronomers use aspects of the process of science in their research.
  • Discovery boxes explore interesting supplementary topics, providing insight into how scientific knowledge evolves and emphasizing the process of science.

Art and visual aids

  • Compound art employs multiple-part images to capture all aspects of a complex subject.

New and updated features of this title

Encourage conceptual understanding

  • UPDATED: Science reflects current research and discoveries from the New Horizon mission on Pluto, the Mars Maven mission on Mars, to new discovery of a potentially habitable planet around Proxima Centauri.
  • Learning Outcomes have been tightened and are now more concise, measurable, and testable.
  • REVISED: End-of chapter material in all chapters is significantly revised with restructured discussion sections, Big Picture questions, new conceptual questions, and new collaborative and individual activities.

Develop skill building

  • Data Points feature alerts students to the mistakes that students statistically make most often, and why.

Art and visual aids

  • Annotated art employs a proven educational research tool by integrating written and visual information to enhance student understanding of photos and diagrams.
  • EXPANDED: Additional scale markers visually help students understand the difficult-to-comprehend scale of the universe.
