Humans have dreamed of travelling to the stars for as long as we knew that those points of light in the sky were stars like the Sun. Now, in the 21st century, there are actual studies and plans to send interstellar space probes to the nearest stars. Probably to Alpha Centauri which is only 4.3 light years away. Only! What is the history of plans to get to the nearest star? And what are the plans today to make these ideas a reality?

Fifty years ago, a young astronomer named Frank Drake pointed a radio telescope at nearby stars in the hope of picking up a signal from an alien civilization. Thus began one of the boldest scientific projects in history, the Search for Extraterrestrial Intelligence (SETI). But after a half century of scanning the skies, astronomers have little to report but an eerie silence---eerie because many scientists are convinced that the universe is teeming with life.

Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces listeners to the science of near-Earth objects - its history, applications, and ongoing quest to find near-Earth objects before they find us.

A manned mission to Mars has been the dream of humanity at least since the 19th century, when we first saw details of the surface and thought there might be canals filled with water there. Here I’ve looked at the history of unmanned exploration of Mars over the last 50-plus years, proposed missions to Mars, Mars settlements, and other major issues regarding traveling to and living on Mars. Some proposals have lots of details of proposed scenarios, if you want to know all of the engineering and scientific analysis work.

This book gets into the history of the JWST, the instruments it carries, new observations, and ideas of what these anomalies mean. We review some of the most important observations made to date, and finally, some theories of how to explain these incredible views of the early reality of the Universe.

This audiobook is an exploration of infinity and new understandings of our universe which have come to light in recent decades.

In the year 1984, many Americans began to fear that the "surveillance state" predicted by George Orwell might be coming to pass. As a result, legendary writer and ufologist Gray Barker decided to revisit - and hopefully encapsulate - the strange case of Albert K. Bender, who was famously "hushed up" by three Men in Black in 1953 - despite heading up the largest and most successful civilian UFO organization in the world.

In order to provide listeners with a comprehensive understanding of the information presented in this book, it is important to include a section dedicated to references. The following references have been used to compile the information about the mysterious alien planet, Proxima B. One of the primary sources for information on Proxima B is the groundbreaking research conducted by the European Southern Observatory (ESO).

The Well-Planned Universe provides evidence-based insights into the nature of our world, ourselves, and the universe beyond. The book explains how recent developments in computer science along with evidence from physics, astronomy, chemistry, and biology reveal that there is more to the universe and ourselves than most people realize.

NASA has plans to land on the Moon again in 2024 and then build a Moon base following that. What is the history of plans to build a base on the Moon and what are all the issues involved? Where should the base be built and what will be do once we have long term habitation on the Moon? There are lots of ideas and lots of issues to consider. My hope is that the reader will learn about all of the issues important to building a Moon Base to better understand what will be required. You might even want to become a Moon Base resident!

The Universe is a very big place and has many mysteries. Most people don’t realize just how mysterious it is. Scientists are stumped by many of the conundrums which Astronomy reveals. In this book, I want to give listeners a sense of the grandeur, mystery, and puzzles which the Universe poses to scientists. When you realize how incredible our Universe really is you may be surprised. We used to think the Sun was the center of the Universe. Now we know our solar system is just one of billions. Most of the matter in the Universe is also missing.

There is a lot of interest these days in space exploration. After 50 years, we are looking at going back to the Moon to build a base and planning early for a manned trip to Mars. After that, further exploration and settlement of the Solar System will be on the table. One of the main limiting factors for all of this space exploration are the types of rockets and rocket engines available to get there.

Namaste: and welcome to The Humanities in Medicine Podcast Experience. I am your host, visionary, and producer: Dr. Watson. Over twenty years ago, I found myself facing a conundrum in my dealings inside the medical community as a medical student, surgical house officer, and later physician. I observed health care inequities at every level, with oftentimes blatantly horrible aberrations being committed against patients and communities of color, or BIPOC. When I voiced my observations and opin...

This book is an overview of both the history of aliens and UFOs, as well as a review of hidden aerospace and propulsive technologies. Where did these technologies come from? And how have they developed in the intervening years? Also, I try to answer some questions of how likely some of these claims are - because some things having to do with UFOs and aliens are much more documented than others. There are also many alien-related and secret programs that most of you listeners may have never heard of. The most interesting ones are summarized here.
