Showing results for "life" in Astronomy

For decades, books, movies, television shows, and conspiracy theories have speculated about the existence of life on other planets. But how possible is it that we are alone in the universe? How likely is it we’ll find a habitable, Earth-like planet? How come we have not already seen signs of extraterrestrial life? Join astrophysicist Sarah Rugheimer to reveal what we know about detecting life on other planets.

Described as the "ultimate engineer" during his career at NASA, George M. Low was a visionary architect and leader from the agency's inception in 1958 to his retirement in 1976. As chief of manned spaceflight at NASA, Low was instrumental in the Mercury, Gemini, and Apollo programs. Low's pioneering work paved the way for President Kennedy's decision to make a lunar landing NASA's primary goal in the 1960s.

Already internationally acclaimed for his elegant, lucid writing on the most challenging notions in modern physics, Sean Carroll is emerging as one of the greatest humanist thinkers of his generation as he brings his extraordinary intellect to bear not only on the Higgs boson and extra dimensions but now also on our deepest personal questions. Where are we? Who are we? Are our emotions, our beliefs, and our hopes and dreams ultimately meaningless out there in the void?

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.

Are we on the brink of discovering the first ever evidence that aliens exist? Join astronomer Professor Alan Duffy on his search to answer this question, as he speaks to a new generation of alien hunters embarking on the greatest hunt for extraterrestrials that’s ever been undertaken.

In late 2017, scientists at a Hawaiian observatory glimpsed a strange object soaring through our inner solar system. Astrophysicist Avi Loeb conclusively showed it was not an asteroid; it was moving too fast along a strange orbit and leaving no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilisation.

We understand the stars at a much deeper level, not as legendary figures connected with constellations, but as engines of matter, energy, and the raw material of life itself. The Life and Death of Stars introduces you to this story in 24 half-hour lectures that lead you through the essential ideas of astrophysics - the science of stars. Your guide is Professor Stassun, an award-winning teacher and noted astrophysicist. He provides lively, eloquent, and authoritative explanations at a level suitable for science novices as well as for those who already know their way around the starry sky.

In 2017, Avi Loeb, Chair of Harvard's Astronomy Department, went public with a theory that shook the scientific community - our solar system has been visited by advanced alien technology. His provocative and persuasive argument (and internationally bestselling book Extraterrestrial) has opened thousands of minds to the existence of intelligent life beyond Earth. This book tackles the huge question of what happens next?

In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century?

We have the impression that the solar system is perfectly regular like a clock or a planetarium instrument. On a short time scale it is. But seen in a longer perspective, the planets and their satellites have exciting lives, full of events - for example, did you know that Saturn's moon, Titan, boasts lakes which contain liquid methane surrounded by soaring hills and valleys, exactly as the earth did before life evolved on our fragile planet?

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

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?

The search for Planet B. Why is Earth so special? And where are the aliens? Dr Matt Agnew takes us through this fun, information-packed, fascinating look at life in space. Sit back, relax, let your imagination run wild and enjoy this scientific journey.

Are we alone in the universe? This is one of the most profound issues facing mankind - and one of the unresolved questions that science may finally be able to answer in this century. These 24 mind-expanding lectures reveal the cutting-edge research leading scientists to believe that life is not exclusively the domain of Earth. Professor Close offers an unparalleled look at the subject of life and the mysteries that remain.

The Martians explores the CIA's top-secret search for the Martians, multiple photos of strange anomalies, and the latest revelations about the environment and water on Mars. And most tantalizing of all: Did an ailing Martian race come to Earth in past eons and were they confused with gods? The questions concerning life on Mars - then and now - are many. The answers are astounding.

This audiobook narrated by Juliet Stevenson shares the story of a world-renowned physicist who seeks gravity’s true nature and finds wisdom in embracing its force in her life.

Long before space travel was possible, the idea of life beyond Earth transfixed humans. In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy. Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks listeners to imagine - and choose among-five scenarios for finding life.

According to the prevailing scientific paradigm, the universe tends toward randomness; it functions according to laws without purpose, and life is an accident devoid of meaning. Thanks to a new understanding of evolution, as well as recent advances in our understanding of the phenomenon known as emergence, a new cosmic narrative is taking shape: Nature’s simplest “parts” come together to form ever-greater “wholes” in a process that has no end in sight. Bobby Azarian explains the science behind this new view of reality and explores what it means for all of us.

Are the physical laws of our universe finely tuned, such that life can exist? What does this imply about how our universe formed? Questions like these are examined in Nature's Balancing Act, presented for a wide audience.

It was not easy being a woman of ambition in early 20th-century England, much less one who wished to be a scientist. Cecilia Payne-Gaposchkin overcame prodigious obstacles to become a woman of many firsts: the first to receive a PhD in astronomy from Radcliffe College, the first promoted to full professor at Harvard, the first to head a department there. And, in what has been called "the most brilliant PhD thesis ever written in astronomy", she was the first to describe what stars are made of.
