A practical introduction to astronomy focusing on critical thinking and our place in the universe
The Essential Cosmic Perspective builds on its long tradition of effective pedagogy and comprehensive coverage to provide non-science majors with a thoroughly engaging and up-to-date introduction to astronomy. As respected teachers and active researchers, the authors present astronomy using a coherent narrative and a thematic approach to guide students through connecting ideas.

The 9th Edition features major scientific updates and recent discoveries that focus on the possibility of life in the universe and provide modern contexts to help students see astronomy as relevant to their worlds. A new focus across science on cultural diversity among scientists and ethics offers inclusive content and a basis for group discussions. The wealth of Mastering Astronomy resources, written and created by the authors, carry the coherent and cohesive approach of the book to the new and expanded digital tools

Jeffrey Bennett, a recipient of the American Institute of Physics Science Communication Award, holds a B.A. in biophysics (UC San Diego) and an M.S. and Ph.D. in astrophysics (University of Colorado). He specializes in science and math education and has taught at every level from preschool through graduate school. Career highlights include serving 2 years as a visiting senior scientist at NASA headquarters, where he developed programs to build stronger links between research and education, proposing and helping to develop the Voyage scale model solar system on the National Mall (Washington, DC), and developing the free app Totality by Big Kid Science to help people learn about total solar eclipses. He is the lead author of textbooks in astronomy, astrobiology, mathematics, and statistics and of critically acclaimed books for the public including Beyond UFOs (Princeton University Press), Math for Life (Bid Kid Science), What Is Relativity? (Columbia University Press), On Teaching Science (Big Kid Science), and A Global Warming Primer (Big Kid Science). He is also the author of six science picture books for children, titled Max Goes to the Moon, Max Goes to Mars, Max Goes to Jupiter, Max Goes to the Space Station, The Wizard Who Saved the World, and I, Humanity; all six have been launched to the International Space Station and read aloud by astronauts for NASA's Story Time From Space program.

Megan Donahue is a University Distinguished Professor in the Department of Physics and Astronomy at Michigan State University (MSU), a Fellow of the American Physical Society and of the American Association for the Advancement of Science. She was the President of the American Astronomical Society from 2018-2020. Her research, published in over 200 articles, exploits x-ray, UV, infrared, and visible light to study galaxies and clusters of galaxies: their contents--dark matter, hot gas, galaxies, active galactic nuclei--and what they reveal about the contents of the universe and how galaxies form and evolve. She grew up on a farm in Nebraska and received an S.B. in physics from MIT, where she began her research career as an x-ray astronomer. She has a Ph.D. in astrophysics from the University of Colorado. Her Ph.D. thesis on theory and optical observations of intergalactic and intracluster gas won the 1993 Robert Trumpler Award from the Astronomical Society for the Pacific for an outstanding astrophysics doctoral dissertation in North America. She continued postdoctoral research as a Carnegie Fellow at Carnegie Observatories in Pasadena, California, and later as an STScI Institute Fellow at Space Telescope. Megan was a staff astronomer at the Space Telescope Science Institute until 2003, when she joined the MSU faculty. She is also actively involved in advising national and international astronomical facilities and NASA, including planning future NASA missions. Megan is married to Mark Voit. They collaborate on many projects, including this textbook series, many peer-reviewed jointly-authored astrophysics papers, and the adventure of parenting of three adult children, Michaela, Sebastian, and Angela. Megan has run three full marathons, including Boston. These days she runs trails with friends and plays piano and bass guitar in garage bands for fun and no profit.

Nicholas Schneider is a full professor in the Department of Astrophysical and Planetary Sciences at the University of Colorado and a researcher in the Laboratory for Atmospheric and Space Physics. He received his B.A. in physics and astronomy from Dartmouth College in 1979 and his Ph.D. in planetary science from the University of Arizona in 1988. His research interests include planetary atmospheres and planetary astronomy. One research focus is the odd case of Jupiter's moon Io. Another is the mystery of Mars's lost atmosphere, which he is helping to answer by leading the Imaging UV Spectrograph team on NASA's MAVEN mission now orbiting Mars. Nick enjoys teaching at all levels and is active in efforts to improve undergraduate astronomy education. Over his career he has received the National Science Foundation's Presidential Young Investigator Award, NASA's Exceptional Scientific Achievement Medal, in addition to university and national teaching awards. Off the job, Nick enjoys exploring the outdoors with his family and figuring out how things work.

Mark Voit is a full professor in the Department of Physics and Astronomy and served as Associate Dean for Undergraduate Studies at Michigan State University. He earned his A.B. in astrophysical sciences at Princeton University and his Ph.D. in astrophysics at the University of Colorado in 1990. He continued his studies at the California Institute of Technology, where he was a research fellow in theoretical astrophysics, and then moved on to Johns Hopkins University as a Hubble Fellow. Before going to Michigan State, Mark worked in the Office of Public Outreach at the Space Telescope, where he developed museum exhibitions about the Hubble Space Telescope and helped design NASA's award-winning HubbleSite. His research interests range from interstellar processes in our own galaxy to the clustering of galaxies in the early universe, and he is a Fellow of the American Association for the Advancement of Science. He is married to coauthor Megan Donahue and cooks her terrific meals. Mark likes getting outdoors whenever possible and particularly enjoys running, mountain biking, canoeing, orienteering, and adventure racing. He is also author of the popular book Hubble Space Telescope: New Views of the Universe.
