Astronomy History

Does life exist on Mars? The question has captivated humans for centuries, but today it has taken on new urgency. NASA plans to send astronauts to Mars orbit by the 2030s. SpaceX wants to go by 2024, while Mars One wants to land a permanent settlement there in 2032. As we gear up for missions like these, we have a responsibility to think deeply about what kinds of life may already inhabit the planet - and whether we have the right to invite ourselves in.

Nothing captivates the human imagination like the vast unknowns of space. Ancient petroglyphs present renderings of the heavens, proof that we have been gazing up at the stars with wonder for thousands of years. Since then, mankind has systematically expanded our cosmic possibilities. What were once flights of fancy and dreams of science fiction writers have become nearly routine. Space travel is a sometimes heroic, sometimes humorous, and always dangerous journey fraught with perils. Space Oddities brings unknown, offbeat, and obscure stories of space to life.

In his final book, Helias Doundoulakis demystifies Arecibo for the novice, from dreams to drawings. The chronological account of the iconic telescope is made plain for all to see, which spanned six decades. Read how his brother, George Doundoulakis, undertook its conception and fielding, finally winning patent rights for his brother Helias, CIA director William Casey, and Gus Michalos. Follow the inseparable brothers on their journey of courage, inspiration, and brilliance that advanced the design of Arecibo and inspired generations of space scientists for years to come.

In the sixteenth century, Nicolaus Copernicus dared to go against the establishment by proposing that Earth rotates around the Sun. Having demoted Earth from its unique position in the cosmos to one of mediocrity, Copernicus set in motion a revolution in scientific thought. This perspective has influenced our thinking for centuries. However, recent evidence challenges the Copernican Principle, hinting that we do in fact live in a special place, at a special time, as the product of a chain of unlikely events.

Mapping the Heavens provides a tour of the "greatest hits" of cosmological discoveries - the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is at the forefront of the research - an astrophysicist who literally creates maps of invisible matter in the universe.

In the scorching summer of 1878, with the Gilded Age in its infancy, three tenacious and brilliant scientists raced to Wyoming and Colorado to observe a rare total solar eclipse. One sought to discover a new planet. Another - an adventuresome female astronomer - fought to prove that science was not anathema to femininity. And a young megalomaniacal inventor, with the tabloid press fast on his heels, sought to test his scientific bona fides and light the world through his revelations.

Decía Carl Sagan que para hacer una tarta de manzana primero hay que crear el universo. Harry Cliff, prestigioso físico de la Universidad de Cambridge, emprende la búsqueda de la receta perfecta recogiendo los ingredientes a través del cosmos, en los núcleos de estrellas moribundas, y retrocediendo en el tiempo hasta la fracción de segundo inmediatamente posterior a la que todo se creó, para entender, entre otras muchas cosas, de dónde proviene la materia.

Sarah Cruddas has been looking to the skies her entire life. Her childhood was spent staring at the moon and hearing stories of the space race, and she worked in a fruit factory to fund her love of the subject. Her subsequent career studying astrophysics and becoming a television host and space journalist has seen her report on space exploration and chase launches across the world. In Look Up Sarah explains why she has always been a passionate advocate for why space should matter - to everyone.

In 1610, Galileo published the Siderius nuncius, or Starry Messenger, a "hurried little masterpiece" in John Heilbron's words. Presenting to the world his remarkable observations using the recently invented telescope, Galileo dramatically challenged our idea of the perfection of the heavens and the centrality of the Earth in the universe. Indeed, the appearance of the little book is regarded as one of the great moments in the history of science.

The airplane changed the course of history. Above all, it changed the history of the United States. When the Wright brothers invented their flying machine, Americans lived in a nation of two dimensions, circumscribed by lines drawn on a conventional map. A century later, their nation existed - in fact, reigned - in three dimensions. Two million Americans slipped the surly bonds of earth daily, carried aloft by aircraft operating in every part of the world.

As smartphones, supercomputers, supercolliders, and AI propel us into an ever more unfamiliar future, How to Speak Science takes us on a rollicking historical tour of the greatest discoveries and ideas that make today's cutting-edge technologies possible. Wanting everyone to be able to "speak" science, YouTube science guru Bruce Benamran explains - as accessibly and wittily as in his acclaimed videos - the fundamental ideas of the physical world: matter, life, the solar system, light, electromagnetism, thermodynamics, special and general relativity, and much more.

In 1977 a group of scientists, artists and writers gathered in a house in Ithaca, New York to work on the most important mixtape ever conceived. It wasn’t from one person to another - it was from Earth to the cosmos. When NASA sent Voyagers 1 and 2 on a grand tour of the outer planets, they knew the ultimate fate of these plucky probes would be to drift forever in the unimaginable void of interstellar space.

In Apollo's Legacy, space historian Roger D. Launius explores the many-faceted stories told about the meaning of the Apollo program and how it forever altered American society. The Apollo missions marked the first time human beings left Earth's orbit and visited another world, and thus they loom large in our collective memory. Many have detailed the exciting events of the Apollo program, but Launius offers unique insight into its legacy as seen through multiple perspectives.

Travel to and from Mars has long been a staple of science fiction. And yet the hurdles - both technological and financial - have kept human exploration of the red planet from becoming a reality. Trailblazing Mars offers an inside look at the current efforts to fulfill this dream. Award-winning journalist Pat Duggins examines the extreme new challenges that will be faced by astronauts on the journey there and back. They'll have to grow their own food, find their own water - and solve their own problems.

During the early and most dangerous years of the cold war, a handful of Americans, led by President Dwight D. Eisenhower, revolutionized spying and warfare. In great secrecy and beyond the prying eyes of Congress and the press, they built exotic new machines that opened up the Soviet Union to surveillance and protected the United States from surprise nuclear attack. Secret Empire is the dramatic story of these men and their inventions, told in full for the first time.

In Search of a Theory of Everything takes listeners on an adventurous journey through space and time on a quest for a unified "theory of everything" by means of a rare and agile interplay between the natural philosophies of influential ancient Greek thinkers and the laws of modern physics.

Galileo Unbound traces the journey that brought us from Galileo's law of free fall to today's geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes.

Since the first humans looked up and saw the sun swallowed by darkness, our species has been captivated by solar eclipses. Astronomer and anthropologist Anthony Aveni explains the history and culture surrounding solar eclipses, from prehistoric Stonehenge to Babylonian creation myths, to a confirmation of Einstein's theory of general relativity, to a spectacle that left New Yorkers in the moon's shadow, to future eclipses that will capture human imaginations.

The Scientific Revolution of the 17th century has often been called a decisive turning point in human history. It represents, for good or ill, the birth of modern science and modern ways of viewing the world. In What Galileo Saw, Lawrence Lipking offers a new perspective on how to understand what happened then, arguing that artistic imagination and creativity as much as rational thought played a critical role in creating new visions of science and in shaping stories about eye-opening discoveries.
