CIT Shows
Rational Alchemy: Phil Plait, Astronomer
Phil Plait of Bad Astronomy and author of the new book "Under Alien Skies," stops by the Captn's Lounge Studio to educate Nigel Aves about how the secrets of the universe, and it continues to expand and create new stars and even galaxies. THIS ONE IS NOT TO BE MISSED!

Produced and edited by T.G. Lewis of the Captn's Lounge Studio for the CiT NETWORK.

Bio: Philip Plait is an American astronomer, author, and science communicator who is known for his popular blog "Bad Astronomy" and his work in promoting scientific skepticism. He was born on September 30, 1964, in Washington, D.C.
Plait received his undergraduate degree in physics from the University of Michigan and his Ph.D. in astronomy from the University of Virginia. He has worked as a researcher at the Goddard Space Flight Center, the Space Telescope Science Institute, and the University of Washington.
Plait is the author of several books, including "Bad Astronomy: Misconceptions and Misuses Revealed, from Astrology to the Moon Landing 'Hoax'" and "Death from the Skies!: The Science Behind the End of the World." He has also appeared on television shows such as "The Daily Show" and "The Colbert Report."
Under the Alien Skies is a book written by Plait, which explores the possibility of life on other planets and the potential for extraterrestrial intelligence. The book delves into the science of astrobiology, including the conditions that would be necessary for life to exist elsewhere in the universe and the methods scientists use to search for it.
Through his writing and outreach, Plait aims to promote scientific literacy and critical thinking, particularly in the areas of astronomy and space science.


Astronomy is the scientific study of celestial objects, phenomena, and the universe as a whole. It is one of the oldest sciences, with a history that dates back thousands of years. Astronomers study everything beyond Earth's atmosphere, including stars, planets, galaxies, black holes, nebulae, comets, asteroids, and even the cosmic microwave background radiation, which is the remnant radiation from the Big Bang.
Here are some key aspects of astronomy:

  1. Observational Astronomy: This involves the direct observation of celestial objects using telescopes, both on the ground and in space. Observational data is crucial for understanding the properties, positions, motions, and interactions of celestial bodies.
Theoretical Astronomy: This branch focuses on developing models, simulations, and mathematical theories to explain astronomical observations and predict new phenomena. It helps to understand the underlying physics and dynamics of celestial objects and the universe.
  • Astrophysics: This is a subset of astronomy that deals with the physics of celestial objects and their interactions. It includes the study of stellar physics, planetary science, cosmology, and the behavior of matter and energy in space.
  • Celestial Objects:
    • Stars: Gaseous spheres that emit light and heat through nuclear fusion reactions in their cores.
    • Planets: Celestial bodies that orbit stars and are large enough to have cleared their orbits of other debris.
    • Galaxies: Large systems of stars, gas, and dust held together by gravity.
    • Nebulae: Clouds of gas and dust in space, often the birthplaces of stars.
    • Black Holes: Extremely dense regions in space where gravity is so strong that nothing, not even light, can escape their grasp.
    • Exoplanets: Planets that orbit stars outside our solar system.
  • The Big Bang Theory: This is the prevailing cosmological model that suggests the universe originated from a singular point of extremely high density and temperature approximately 13.8 billion years ago. The universe has been expanding ever since.
  • Telescopes: These instruments are essential tools for astronomers to observe distant objects. They collect and focus light, enabling scientists to study celestial phenomena in detail. Ground-based telescopes observe visible light and other wavelengths, while space telescopes, like the Hubble Space Telescope, can observe beyond the interference of Earth's atmosphere.
  • Important Space Missions: Over the years, various space missions have provided valuable data and insights into the cosmos. Missions like the Voyager probes, the Kepler Space Telescope, the Mars rovers, and the Cassini spacecraft have significantly contributed to our understanding of the universe.

  • Astronomy continues to be an exciting and rapidly evolving field, with ongoing research leading to new discoveries and expanding our knowledge of the cosmos and our place in it. It has profound implications for our understanding of the origin and fate of the universe and is closely linked to other scientific disciplines, such as physics, chemistry, and planetary science.
