The International Astronomical Union formalized the naming of meteor showers in 2006. Each newly discovered shower now is assigned a unique and officially recognized name, number, and 3-letter code. Close to a thousand possible meteor showers have since been reported, over a hundred in the cause of writing this book. Atlas of Earth's Meteor Showers takes stock of all reported detections by going back to the combined video and radar data in hand at the end of 2021, in order to weed out duplicates and false detections. Maps were created that show the direction of motion of meteors (their radiant) during 5-day and 10-day intervals throughout the year. All 500+ showers recognized are briefly described from their radiant, speed, and orbital elements, and the meteoroid mass distribution index was calculated. Physical properties of the meteoroids were derived from their beginning, peak and end height, from their deceleration in Earth's atmosphere, and from spectroscopic information. Candidate parent bodies are mentioned and the age of the stream was calculated from the dispersions in orbital elements and from the meteor magnitude distribution index. A brief history is given of the shower's discovery, of when features were first recognized, and of results from dynamical modeling, all with references to the literature. - Presents approximately 400 detailed meteor shower maps that show what showers are active on a given night for visual, video, and radar observers - Provides thorough descriptions of each shower that can be used in planetary astronomy and for meteor observing sessions, the discovery of new showers, and planetary defense - Highlights periodic, unusual showers that may be expected on a given night based on past occurrences that are important to satellite hazard avoidance and meteor storm chasing

Meteor Showers and their Parent Comets is a unique handbook for astronomers interested in observing meteor storms and outbursts. Spectacular displays of 'shooting stars' are created when the Earth's orbit crosses a meteoroid stream, as each meteoroid causes a bright light when it enters our atmosphere at high speed. Jenniskens, an active meteor storm chaser, explains how meteoroid streams originate from the decay of meteoroids, comets and asteroids, and how they cause meteor showers on Earth. He includes the findings of recent space missions to comets and asteroids, the risk of meteor impacts on Earth, and how meteor showers may have seeded the Earth with ingredients that made life possible. All known meteor showers are identified, accompanied by fascinating details on the most important showers and their parent comets. The book predicts when exceptional meteor showers will occur over the next fifty years, making it a valuable resource for both amateur and professional astronomers.

Ancient calendars found around the world are designed to end one point in time. They communicate an urgent warning to everyone alive today! Complex bronze and gold clocks with multiple dials are found in museums around the world. Why they have such advanced intricacy has stumped scientists for hundreds of years.This book reveals why the ancients built so many pyramids, observatories as well as those complex gold and bronze clocks with more than one dial. It surprised me greatly to discover that their various complex designs in one way or another converge on 21 December 2012. It amazes me that ancient cultures separated by thousands of miles of geography and thousands of years in chronology agree so precisely in the cyclical nature of time, history and prophecy, which is history written in advance. The most famous example is the Mayan-Aztec calendar, which ends its 25,626-year cycle on that momentous date. Some researchers have also found 21 December 2012 in what is called, the Bible Code. Using very different research methods, I discovered it in the Bible's book of Revelation and Daniel's prophecies. It is one of the most important dates in the plan of God for all humanity!
