Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. As one of the founders of the discipline, James Keeler, said, Astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space–what they are, rather than where they are." Among the subjects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. Emissions from these objects are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, astrophysicists apply concepts and methods from many disciplines of physics, including classical mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics.
Neil deGrasse Tyson is an American astrophysicist, author, and science communicator. Tyson studied at Harvard University, the University of Texas at Austin, and Columbia University. From 1991 to 1994, he was a postdoctoral research associate at Princeton University. In 1994, he joined the Hayden Planetarium as a staff scientist and the Princeton faculty as a visiting research scientist and lecturer. In 1996, he became director of the planetarium and oversaw its $210 million reconstruction project, which was completed in 2000. Since 1996, he has been the director of the Hayden Planetarium at the Rose Center for Earth and Space in New York City. The center is part of the American Museum of Natural History, where Tyson founded the Department of Astrophysics in 1997 and has been a research associate in the department since 2003.
Marcelo Gleiser is a Brazilian physicist and astronomer. He is currently Professor of Physics and Astronomy at Dartmouth College and was the 2019 recipient of the Templeton Prize.
Cosmos is a popular science book written by astronomer and Pulitzer Prize-winning author Carl Sagan. It was published in 1980 as a companion piece to the PBS mini-series Cosmos: A Personal Voyage with which it was co-developed and intended to complement. Each of the book’s 13 illustrated chapters corresponds to one of the 13 episodes of the television series. Just a few of the ideas explored in Cosmos include the history and mutual development of science and civilization, the nature of the Universe, human and robotic space exploration, the inner workings of the cell and the DNA that controls it, and the dangers and future implications of nuclear war. One of Sagan's main purposes for both the book and the television series was to explain complex scientific ideas in a way that anyone interested in learning can understand. Sagan also believed the television was one of the greatest teaching tools ever invented, so he wished to capitalize on his chance to educate the world. Spurred in part by the popularity of the TV series, Cosmos spent 50 weeks on the Publishers Weekly best-sellers list and 70 weeks on the New York Times Best Seller list to become the best-selling science book ever published at the time. In 1981, it received the Hugo Award for Best Non-Fiction Book. The unprecedented success of Cosmos ushered in a dramatic increase in visibility for science-themed literature. The success of the book also served to jumpstart Sagan's literary career. The sequel to Cosmos is Pale Blue Dot: A Vision of the Human Future in Space (1994).
Manhattanhenge, also called the Manhattan Solstice, is an event during which the setting sun or the rising sun is aligned with the east–west streets of the main street grid of Manhattan, New York City. The astrophysicist Neil deGrasse Tyson claims to have coined the term, by analogy with Stonehenge. The sunsets and sunrises each align twice a year, on dates evenly spaced around the summer solstice and winter solstice. The sunset alignments occur around May 28 and July 13. The sunrise alignments occur around December 5 and January 8.
Marc Kuchner is an American astrophysicist, a staff member at NASA's Goddard Space Flight Center (GSFC) known for work on images and imaging of disks and exoplanets. Together with Wesley Traub, he invented the band-limited coronagraph, a design for the proposed Terrestrial Planet Finder (TPF) telescope, also to be used on the James Webb Space Telescope (JWST). He is also known for his novel supercomputer models of planet-disk interactions and for developing the ideas of ocean planets, carbon planets, and helium planets. Kuchner appears as an expert commentator in the National Geographic television show "Alien Earths" and frequently answers the "Ask Astro" questions in Astronomy Magazine. He currently serves as the principal investigator of the citizen science websites Disk Detective and Backyard Worlds.
Nova ScienceNow is a spinoff of the long-running and venerable PBS science program Nova. Premiering on January 25, 2005, the series was originally hosted by Robert Krulwich, who described it as an experiment in coverage of "breaking science, science that's right out of the lab, science that sometimes bumps up against politics, art, culture". At the beginning of season two, Neil deGrasse Tyson replaced Krulwich as the show's host. Tyson announced he would leave the show and was replaced by David Pogue in season 6.
Adam Frank is an American physicist, astronomer, and writer. His scientific research has focused on computational astrophysics with an emphasis on star formation and late stages of stellar evolution. His work includes studies of exoplanet atmospheres and astrobiology. The latter include studies of the generic response of planets to the evolution of energy-intensive civilizations (exo-civilizations).
Cosmos: A Spacetime Odyssey is a 2014 American science documentary television series. The show is a follow-up to the 1980 television series Cosmos: A Personal Voyage, which was presented by Carl Sagan on the Public Broadcasting Service and is considered a milestone for scientific documentaries. This series was developed to bring back the foundation of science to network television at the height of other scientific-based television series and films. The show is presented by astrophysicist Neil deGrasse Tyson, who, as a young high school student, was inspired by Sagan. Among the executive producers are Seth MacFarlane, whose financial investment was instrumental in bringing the show to broadcast television, and Ann Druyan, a co-author and co-creator of the original television series and Sagan's wife. The show is produced by Brannon Braga, and Alan Silvestri composed the score.
