In 1927 Georges Lemaître argued that our universe is expanding, a conclusion rendered more startling by the astronomical data that backed it up, presented two years later by Edwin Hubble. The speed of this expansion is governed by Hubble's constant, and Discordance tells its troubled history.

As a young boy Frank Kovac Jr. fell deeply in love with stargazing, painting glow-in-the-dark constellations on his bedroom wall and inviting friends to an observatory he built in his Chicago backyard. As he reached adulthood, Kovac did not let go of his childhood dreams of reaching the stars. He began scheming to bring the universe home. While working at a paper mill as a young man, Kovac tirelessly built a 22-foot rotating globe planetarium in the woods.

Did you know that humans have only been able to study five percent of the universe? The other 95 percent of our universe is invisible! There are several parts of the universe that we haven't seen yet, as light from there hasn't reached us yet! If the mechanisms of space pique your interest, you have come to the right place.

I am a Fellow of the Royal Astronomical Society and currently sit on the council. I presented a series of astronomy talks on YouTube called ‘The Hitch Hikers Guide to the Cosmos. I also present lectures on cruise ships all over the world, and to various clubs and societies at home. I have a monthly astronomy feature on BBC Radio York and my own weekly Astronomy Show on a community radio station called Drystone Radio, which can be heard on line. I also write a monthly ‘What’s in the night sky?’ feature for the Craven Herald newspaper which covers the Yorkshire Dales.

A podcast about black holes would explore the most mysterious and captivating phenomena in the universe. Each episode would delve into the science behind black holes, from their formation through the collapse of massive stars to their immense gravitational pull that warps space and time. Listeners would learn about the different types of black holes, such as stellar, supermassive, and primordial, and hear from astrophysicists who study these enigmatic objects. The podcast would also cover the latest discoveries, theories, and the technology used to observe black holes, making complex concepts ...

Mars, the red planet, is ingrained in our culture, from David Bowie's extra-terrestrial spiders to Captain Scarlet to War of the Worlds. It has inspired hundreds of authors, scientists and science-fiction writers - but why? What is it about this particular planet that makes it so intriguing? Ancient mythologies defined Mars as a violent harbinger of war, star-gazers puzzled over its peculiar motion, and astrologers defined human personalities by its position and bizarre dance through the sky.

An extraterrestrial colony, in some form, may already exist, just awaiting discovery. But the greatest impediment to such an important scientific discovery may not be technological, but political. No scientific endeavor can be launched without a budget, and matters of money are within the arena of politicians. Dr. Ben Bova explores some of the key players and the arguments waged in a debate of both scientific and cultural priorities.

Stephen Hawking’s phenomenal, multimillion-copy bestseller, A Brief History of Time, introduced the ideas of this brilliant theoretical physicist to readers all over the world. Now, in a major publishing event, Hawking returns with a lavishly illustrated sequel that unravels the mysteries of...

Are there more than four dimensions to physical reality? Is it possible to traverse time as well as space? Is there a reality beyond our traditional concepts of time and space? The startling discovery of modern science is that our physical universe is actually finite. Scientists now acknowledge that the universe had a beginning. They call the singularity from which it all began the "Big Bang".

Planet Earth has been a familiar concept for a mere fraction of recorded history. Until about the mid-1600s, most humans thought of Earth as immobile, likely either dim or simply invisible from the Moon or anywhere else in the heavens, and not (like the planets) participating in what Galileo...

Weißt du, wie viel Sternlein stehen? Mehr als man sich vorstellen kann - und alle erzählen sie eine Geschichte über das Universum. Dank Gamma Draconis wissen wir, dass die Erde sich um ihre Achse dreht, und 61 Cygni hat uns verraten, wie große der Kosmos ist. Die Sterne nehmen uns mit auf die Suche nach außerirdischem Leben, erklären, wie schwarze Löcher funktionieren und warum die Dinosaurier ausgestorben sind. Und sie zeigen, wie wir durch den Weltraum reisen und andere Planeten besiedeln könnten.

Ka-boom! probes extremes of size and speed, depth and density, and reveals the stickiest, sweetest, smelliest and nastiest substances known to science. In an unabashed celebration of the exceptional, David Darling takes an enlightening journey through the universe's weirdest and most wonderful extremes.

The Cold War is usually thought of in terms of fear, potential nuclear war, and espionage. While these were elements of the years between the end of World War II and the 1990s, the competition between the US and the USSR had some real benefits. Perhaps, the best and most impressive accomplishments during this time resulted from the Space Race.

Carl Edward Sagan (November 9, 1934-December 20, 1996), born in Brooklyn, NY, was an American astronomer and astrophysicist. His best-known scientific contribution was his research on the possibility of extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by exposure to light. The following is a lecture Sagan gave in 1977 during which he discussed the place, scale and geometry of earth–the third planet from the Sun, formed 4.5 billion years ago–in our solar system.

Have you ever wondered if we are alone in the universe, and if not, are alien races already visiting the Earth? Only when we have a basic knowledge and understanding of the topic can we make an informed decision on whether UFOs are real, and this book will help the reader make that choice. It will offer a basic, but broad overview of the UFO phenomenon from ancient times to modern, including UFO-related topics such as crop circles and the mysterious men in black.

Travel the Universe as you explore the wonders of outer space like never before! I combined all three exciting volumes into one incredible fact book for space lovers, students, and the curious.

On April 24, 1990, the Space Shuttle Discovery lifted off from Kennedy Space Center on the Space Shuttle Program’s 35th mission, but this was no ordinary mission. In its payload bay, Discovery was carrying the Hubble Space Telescope, with the objective of putting the telescope into orbit.

The fascinating science behind the eventual end to everything - from the individual to all existence. Although we may try to keep it tucked at the back of our minds, most of us are aware of our own mortality. But few among us know what science, with the help of insights yielded from groundbreaking new research, has to say about death on a larger scale. Enter astronomer Chris Impey, who chronicles the death of the whole shebang.
