You are reading the word now right now. But what does that mean? What makes the ephemeral moment "now" so special? Its enigmatic character has bedeviled philosophers, priests, and modern-day physicists from Augustine to Einstein and beyond. Einstein showed that the flow of time is affected by both velocity and gravity, yet he despaired at his failure to explain the meaning of now. Equally puzzling: Why does time flow? Some physicists have given up trying to understand and call the flow of time an illusion.

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.

After a few billion years of bearing witness to life on Earth, of watching one hundred billion humans go about their day-to-day lives, of feeling unbelievably lonely, and of hearing its own story told by others, The Milky Way would like a chance to speak for itself. All one hundred billion stars and fifty undecillion tons of gas of it. It all began some thirteen billion years ago, when clouds of gas scattered through the universe's primordial plasma just could not keep their metaphorical hands off each other.

One of the leading physicists of her generation, Dr. Chanda Prescod-Weinstein is also one of fewer than one hundred Black American women to earn a PhD from a department of physics. Her vision of the cosmos is vibrant, buoyantly nontraditional, and grounded in Black and queer feminist lineages. Dr. Prescod-Weinstein urges us to recognize how science, like most fields, is rife with racism, misogyny, and other forms of oppression. She lays out a bold new approach to science and society, beginning with the belief that we all have a fundamental right to know and love the night sky.

Buckle up for a joy ride through physics, chemistry, biology, geology, and astronomy. Drawing on conversations with hundreds of the world's top scientists and her own work as an award-winning science writer, Natalie Angier does the impossible: she makes science fascinating and seriously fun, even for those of us who, in Angier's words, "still can't tell the difference between a proton, a photon, and a moron".

In this astonishing rediscovery of the final Apollo moon landings, the acclaimed author of Chesapeake Requiem reveals that these extraordinary yet overshadowed missions - distinguished by the use of the revolutionary lunar roving vehicle - deserve to be celebrated as the pinnacle of human adventure and exploration.

The study of life and its existence in the universe, known as astrobiology, is now one of the hottest areas of both popular science and serious academic research, fusing biology, chemistry, astrophysics, and geology. Lewis Dartnell tours its latest findings, and explores some of the most fascinating questions in science. Could life emerge on other planets or moons? Could alien cells be based on silicon rather than carbon, or need ammonia instead of water?

When asked to explain Relativity simply, Albert Einstein himself once joked, “Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's Relativity.” But when most normal people without advanced training attempt to study the subject seriously, they’re quickly weighed down by the mathematics…

In The Elephant in the Universe, Govert Schilling explores the fascinating history of the search for dark matter. Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature.

As the 50th anniversary of the first lunar landing approaches, the award-winning historian and perennial New York Times best-selling author takes a fresh look at the space program, President John F. Kennedy’s inspiring challenge, and America’s race to the moon.

Since its 2009 launch, the Kepler satellite has discovered more than 2,000 exoplanets, or planets outside our solar system. More exoplanets are being discovered all the time, remarkable in their variety. Astronomer Michael Summers and physicist James Trefil explore these remarkable recent discoveries: planets revolving around pulsars, planets made of diamond, planets that are mostly water, and numerous rogue planets wandering through the emptiness of space.

In Journey Through The Solar System, you can join the experience of a lifetime without leaving your home. Get ready for an unforgettable space holiday! You're about to launch on a voyage beyond your wildest dreams, touring the marvels of our Solar System (the sun, planets, comets, and asteroids) and the mysteries of the cosmos.

The solar system most of us grew up with included nine planets, with Mercury closest to the sun and Pluto at the outer edge. Then, in 2005, astronomer Mike Brown made the discovery of a lifetime: a tenth planet, Eris, slightly bigger than Pluto. But instead of its resulting in one more planet being added to our solar system, Brown’s find ignited a firestorm of controversy that riled the usually sedate world of astronomy and launched him into the public eye.

The Space Barons is the story of a group of billionaire entrepreneurs who are pouring their fortunes into the epic resurrection of the American space program. Nearly a half century after Neil Armstrong walked on the moon, these Space Barons—most notably Elon Musk and Jeff Bezos, along with Richard Branson and Paul Allen—are using Silicon Valley-style innovation to dramatically lower the cost of space travel and send humans even further than NASA has gone.

Legendary "space statesman" Buzz Aldrin speaks out as a vital advocate for the continuing quest to push the boundaries of the universe as we know it. As a pioneering astronaut who set foot on the moon during mankind’s first landing with Apollo 11 - and an aerospace engineer who designed an orbital rendezvous technique critical to future planetary landings - Aldrin has a vision, and in Mission to Mars he plots out the path he proposes, one that will take humans to Mars by 2035.

David K. Stumpf demystifies the intercontinental ballistic missile program that was conceived at the end of the Eisenhower administration as a key component of the US nuclear strategy of massive retaliation. Although its nuclear warhead may have lacked power relative to that of the Titan II, the Minuteman more than made up for this in terms of numbers and readiness to launch - making it the ultimate ICBM.

What is life? This is among the most difficult open problems in science, right up there with the nature of consciousness and the existence of matter. All the definitions we have fall short. None help us understand how life originates or the full range of possibilities for what life on other planets might look like. In Life as No One Knows It, physicist and astrobiologist Sara Imari Walker argues that solving the origin of life requires radical new thinking and an experimentally testable theory for what life is.

In the most authoritative book ever written about Apollo, David Whitehouse reveals the true drama behind the mission, telling the story in the words of those who took part - based around exclusive interviews with the key players. This enthralling book takes us from the early rocket pioneers to the shock America received from the Soviets' launch of the first satellite, Sputnik; from the race to put the first person into space, through President Kennedy's enthusiasm and later doubts, to the astronauts' intense competition to leave the first footprint.

My beginner's book is your ticket to one of the coolest and most mysterious subjects out there. This isn't your average physics book. It's a portal to understanding the stuff that makes up... well, everything! Subatomic particles. Do not let their size fool you; they have a massive impact on the world around you—the fundamental part of how everything works and not as complex as you might fear.

Our understanding of the Universe is about to transform at all levels, from the Planck scale to the vast reaches of space. Recent scientific discoveries show that the information that upholds all of our modern technologies is exactly the same as the universal in-formation that underpins, pervades, and is all we call physical reality. Exploring how information is more fundamental than energy, matter, space, or time, Jude Currivan examines the latest research across many fields of study and many scales of existence to show how our Universe is in-formed and holographically manifested.
