Mark Twain said, “Get your facts first, then you can distort them as you please.” Pseudoscience adheres to this adage, but are their distortions deliberate, the result of scientific ignorance, or due to a deep desire for extraordinary possibilities? In our quest to understand the universe, how can we be sure our conclusions are correct? Human beings have evolved to find meaningful patterns in nature, but sometimes the patterns we see are just figments of our imagination — or perhaps the result of wishful thinking.

The Sun, as our nearest star, is of enormous importance for life on Earth, providing the warm radiation and light which allowed complex life to evolve. The Sun plays a key role in influencing our climate, while solar storms and high-energy events can threaten our communication infrastructure and satellites.

Our nearest planetary neighbor has been the subject of endless fascination and wide-ranging theories throughout history. Is there life on Mars? Was there ever life on Mars? What was the atmosphere like thousands or millions of years ago? From Percival Lowell, who built his own observatory so he could dedicate himself to studying the red planet, to NASA landing the car-sized Curiosity rover in 2012, this book traces Scientific American's coverage of the observation and exploration of Mars.

In 2000, Martin Bojowald, then a 27-year-old post-doc at Pennsylvania State University, used a relatively new theory called loop quantum gravity - a cunning combination of Einstein’s theory of gravity with quantum mechanics - to create a simple model of the Universe. Loop quantum cosmology was born, and with it, a theory that managed to do something even Einstein’s general theory of relativity had failed to do - illuminate the very birth of the Universe.

On June 3, 1769, the planet Venus briefly passed across the face of the sun in a cosmic alignment that occurs twice per century. Anticipation of the rare celestial event sparked a worldwide competition among aspiring global superpowers, each sending their own scientific expeditions to far-flung destinations to time the planet’s trek.

Spectroscopy, the study of the interaction between matter and electromagnetic radiation, may sound complex and esoteric, but at its heart lies a simple and profound idea: the colors of light can reveal the secrets of the universe. From the examination of distant stars to the analysis of molecules in a laboratory, spectroscopy is the key that unlocks the hidden stories encoded in light.

In the two decades since astronomers first discovered the existence of a planet outside of our solar system, “exoplanetology” has become the hottest specialty in astrophysics. Scientists young and old, inspired by the thought of finding either another habitable world or the Holy Grail of space exploration - life itself - flocked to be part of this burgeoning field. With so much brainpower on hand, it’s no wonder that investigative techniques advanced more quickly than anyone would have thought.

Elon Musk founded SpaceX with the mission of making humans a multiplanetary species. In the coming years, SpaceX will launch a crew of 24 people through space and onto Mars, in a new kind of rocket called Starship. Over 80 million miles away, Mars is both desolate, and at the same time, full of limitless potential. Mars holds limitless possibilities. Since the ideal alignment for Earth and Mars only happens once every two years, there is only a small window to get everything right.

NASA audio recordings from Apollo 11 are some of the most important and historic audio recordings ever made. They capture the voices of Neil Armstrong, Buzz Aldrin, and Michael Collins as they made the first-ever landing on the Moon on July 20, 1969.The audio recordings include everything from the astronauts' conversations with Mission Control to their descriptions of the lunar surface and their own feelings about being the first humans to walk on the Moon. They are a fascinating and inspiring record of one of the greatest achievements in human history.NASA has digitized and made available ...

Veteran science journalist Leonard David explores the moon in all its facets, from ancient myth to future "Moon Village" plans. David offers inside information about how the United States, allies, and competitors, as well as key private corporations like Moon Express and Jeff Bezos's Blue Origin, plan to reach, inhabit, and even harvest the moon in the decades to come. Spurred on by the Google Lunar XPRIZE - $30 million for the first to get to the moon and send images home - the 21st-century space race back to the moon has become more urgent, and more timely, than ever.

In 1929, Edwin Hubble announced the greatest discovery in the history of astronomy since Galileo first turned a telescope to the heavens. The galaxies, previously believed to float serenely in the void, are in fact hurtling apart at an incredible speed: the universe is expanding. This stunning discovery was the culmination of a decades-long arc of scientific and technical advancement.

In her graceful, compelling style, Dava Sobel chronicles the history of the Copernican Revolution, relating the story of astronomy from Aristotle to the Middle Ages. In its midst will be her play, And the Sun Stood Still, imagining the dialogue that would have transpired between Rheticus and Copernicus in their months together. As she achieved with her bestsellers Longitude and Galileo's Daughter, Sobel expands the bounds of science writing, giving us an unforgettable portrait of scientific achievement.

Everything we know about how planets form and how life arises suggests that human civilization on Earth should not be unique. We ought to see abundant evidence of extraterrestrial activity - but we don't. Where is everybody? In this volume in the MIT Press Essential Knowledge series, science and technology writer Wade Roush examines one of the great unsolved problems in science: Is there life, intelligent or otherwise, on other planets?

Project Gemini is a neglected part of the US space program. Sandwiched between the excitement of Project Mercury and the sending of the first American astronauts to space and the euphoria of the Apollo Moon landings, Gemini was a step forward rather than a dramatic leap. However, this project achieved many important firsts, including the first spacewalk, the first rendezvous and docking between two spacecraft, the first flights of more than one week’s duration, and many more.

Over 50 years ago, astronomers launched the world's first orbiting telescope. This allowed them to gaze further into outer space and examine anything that appears in the sky above our heads, from comets and planets to galaxy clusters and stars. Since then, almost 100 space telescopes have been launched from Earth and are orbiting our planet, with 26 still active and relaying information back to us. In Eyes in the Sky, science writer Andrew May takes us on a journey into space.

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.

Wally Schirra was the only one of the original seven NASA astronauts to command a spacecraft in all three pioneering space programs - Mercury, Gemini, and Apollo. This chronicle of his experiences takes us into space on Schirra's 1962 Mercury flight that orbited Earth six times and aboard Gemini for the first rendezvous of two manned craft in space.
