Describing the latest discoveries in astrophysics, the informative and entertaining narrative propels you from our home solar system to the outermost frontiers of space. How do stars live and die? Why did Pluto lose its planetary status? What are the prospects of intelligent life elsewhere in the universe? How did the universe begin? Why is it expanding and why is its expansion accelerating? Is our universe alone or part of an infinite multiverse?
Answering these and many other questions, the authors open your eyes to the wonders of the cosmos, sharing their knowledge of how the universe works. Breathtaking in scope and stunningly illustrated throughout, Welcome to the Universe is for those who hunger for insights into our evolving universe that only world-class astrophysicists can provide. For those who may have felt that Welcome to the Universe was a bit beyond them, this book covers all the essentials in an even more accessible and concise fashion, while imparting real physical insight into how the universe works by the book's end" Richard Gott taught together at Princeton.
This problem book features more than one hundred problems and exercises used in the original course—ideal for anyone who wants to deepen their understanding of the original material and to learn to think like an astrophysicist.
Winner of the Schneider Family Book Award! When Julia finds a slur about her best friend scrawled across the back of the Kingston School for the Deaf, she covers it up with a beautiful albeit illegal graffiti mural.
We come to realize the degree to which truth is bent and shaped by special interests in social, political, and religious affairs. After 40 years in the making, In Search of Destiny brings to you a gripping scientific and spiritual search for human destiny. Are we here to just be born, grow old, and die on planet earth?
Or, is there evidence beyond this? In Search of Destiny draws a decisive conclusion. Our galaxy? The universe? Does extra-terrestrial life exist? How unique is Earth? Will we ever be able to travel to other stars? How realistic are the science fiction accounts of space travel? It is the perfect 'pocket sized' compendium for budding astronomers and armchair lovers of science and science fiction.
Includes information on the planets, and other astrological entities" Popular Books. Fear No Evil by James Patterson. The galaxy goes dark. The universe goes dark. Black holes are left, emitting only a feeble glow of light.
Not with a bang, but with a whimper. All the hydrogen and most of the helium are traceable to the Big Bang, along with a smidgen of lithium. The rest of the elements were later forged in stars. If you are a big fan of the argument that somehow life on Earth is special, then you must contend with an important fact: if I rank the top five elements in the universe—hydrogen, helium, oxygen, carbon, and nitrogen—they look a lot like the ingredients of the human body.
Our galaxy has billion stars, many of them likely surrounded by planets of their own. How important are we in this picture? A depressing revelation for some, who would prefer to feel large. The problem is history. In fact, we occupy a humble corner of the galaxy, which occupies its own humble corner in the universe. Every astrophysicist lives with that reality. Because we are alive, we harbor a special interest in life in the universe. You have to make the star, and then the planet, and then, remembering that life on Earth evolves slowly, you need billions of years of evolution to produce intelligent life.
Therefore, the star has to be long lived. Not all stars live a long time. Your most massive stars are dead after 10 million years or less—not much hope for intelligent life on a planet around those stars, if what happened on Earth is any indication. The interstellar medium is the raw material from which stars are made. Gravity pulls a small knot in the cloud of dust and gas together. As it collapses, it heats up, converting its gravitational potential energy to kinetic energy as it falls inward, eventually becoming hot and dense enough for thermonuclear reactions to take place, and a star is born.
Divide this by the diameter of the Sun, 1. This will tell us how many Suns we would have to lay side by side to reach to the nearest star: 30 million. In other words, the distance to the nearest stars is 3 billion times the diameter of Earth. The stars are tiny specks compared to the enormous distances between them. We now know that our Milky Way is a very flattened structure, a circular disk, roughly , light-years in diameter, but only 1, or so light-years thick.
There is a significant component of the mass of the Milky Way outside the orbit of the Sun that is simply not visible in the form of stars. We call it dark matter. We have inferred its presence solely through its gravitational effect on stellar orbits. Lemoncello's Library! Jake McQuade is the smartest kid in the universe—and he's back to defend his title!

Canadian MIT astrophysicist Sara Seager interweaves the story of her search for meaning and solace after losing her first husband to cancer, her unflagging search for an Earth-like exoplanet and her unexpected discovery of new love. Sara Seager has made it her life's work to peer into the spaces around stars--looking for exoplanets outside our solar system, hoping to find the one-in-a-billion world enough like ours to sustain life.
But with the unexpected death of her husband, her life became an empty, lightless space. Suddenly, she was the single mother of two young boys, a widow at forty, clinging to three crumpled pages of instructions her husband had written for things like grocery shopping--things he had done while she did pioneering work as a planetary scientist at MIT. She became painfully conscious of her Asperger's, which before losing her husband had felt more like background noise.
She felt, for the first time, alone in the universe. In this probing, invigoratingly honest memoir, Seager tells the story of how, as she stumblingly navigated the world of grief, she also kept looking for other worlds. She continues to develop groundbreaking projects, such as the Starshade, a sunflower-shaped instrument that, when launched into space, unfurls itself so as to block planet-obscuring starlight, and she takes solace in the alien beauty of exoplanets.
At the same time, she discovers what feels every bit as wondrous: other people, reaching out across the space of her grief. Among them are the Widows of Concord, a group of women offering consolation and advice, and her beloved sons, Max and Alex.
Most unexpected of all, there is another kind of one-in-a-billion match with an amateur astronomer. Equally attuned to the wonders of deep space and human connection, The Smallest Lights in the Universe is its own light in the dark. Gravitational physicist David Garfinkle and his brother, science fiction writer Richard Garfinkle, tackle these questions and more in Three Steps to the Universe, a tour through some of the most complex phenomena in the cosmos and an accessible exploration of how scientists acquire knowledge about the universe through observation, indirect detection, and theory.
The authors begin by inviting readers to step away from the Earth and reconsider our Sun. What we can directly observe of this star is limited to its surface, but with the advent of telescopes and spectroscopy, scientists know more than ever about its physical characteristics, origins, and projected lifetime. From the Sun, the authors journey further out into space to explore black holes. The Garfinkle brothers explain that our understanding of these astronomical oddities began in theory, and growing mathematical and physical evidence has unexpectedly supported it.
From black holes, the authors lead us further into the unknown, to the dark matter and energy that pervade our universe, where science teeters on the edge of theory and discovery. Returning from the depths of space, the final section of the book brings the reader back down to Earth for a final look at the practice of science, ending with a practical guide to discerning real science from pseudoscience among the cacophony of print and online scientific sources.
Three Steps to the Universe will reward anyone interested in learning more about the universe around us and shows how scientists uncover its mysteries. The authoritative story of the headline-making discovery of gravitational waves—by an eminent theoretical astrophysicist and award-winning writer.
Black holes are dark. That is their essence.
