Showing results for "life-" in Astronomy & Space Science

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?

A hilarious guide to what's real (and what's not) in our vast, beautiful (and terrifying) universe.

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.

Everywhere light goes, It has found that darkness is already there. Darkness is the natural state of the universe. For a star to be born, it takes an astounding number of possibilities to become a reality. From this unlikely alignment, we now have trillions of stars! Thankfully stars would progress to give us light, life, and an observable universe. No one knows how many stars exist, but we will tour a handful of the most famous in our known universe. Sit back and enjoy the world of outer space that spreads before you. Each constellation and luminary has a story that you won’t want to miss!

In the 18th century, the British minister and mathematician Thomas Bayes devised a theorem that allowed him to assign probabilities to events that had never happened before. It languished in obscurity for centuries until computers came along and made it easy to crunch the numbers. Now, as the foundation of big data, Bayes's formula has become a linchpin of the digital economy. But here's where things get interesting: Bayes's theorem can also be used to lay odds on the existence of extraterrestrial intelligence, and on the biggest question of all: how long will humanity survive?

In November 2002, U.S. astronauts Donald Pettit and Kenneth Bowersox, and Russian flight engineer Nikolai Budarin, left on what was to be a routine 14-week mission to maintain the International Space Station. But then, on February 1, 2003, the Columbia exploded beneath them. With the launch program suspended indefinitely, these astronauts had suddenly lost their ride home.

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.

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?

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.

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.

An inspirational memoir of space exploration and hard-won wisdom, from an astronaut who has spent a lifetime making the impossible a reality. Colonel Chris Hadfield has spent decades training as an astronaut and has logged nearly 4,000 hours in space. During this time he has broken into a Space Station with a Swiss army knife, disposed of a live snake while piloting a plane, been temporarily blinded while clinging to the exterior of an orbiting spacecraft, and become a YouTube sensation with his performance of David Bowie's ‘Space Oddity' in space.

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?

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?

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 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?

What is consciousness? Why are we here? Where did it all come from - the laws of nature, the stars, the universe? Humans have been asking these questions forever, but science hasn't succeeded in providing many answers - until now. In The Grand Biocentric Design, Robert Lanza, one of Time magazine's "100 Most Influential People", is joined by theoretical physicist Matej Pavšic and astronomer Bob Berman to shed light on the big picture that has long eluded philosophers and scientists alike.

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.

The science behind the debate raging in modern physics over the disconcerting and uncomfortable realization that just maybe there is, as astronomer Fred Hoyle put it, some sort of "superintellect that has monkeyed with the physics". Written with the non-scientist in mind, this exploration of the big bang, Schroedinger's cat, the chaos of 9/11, the complexity of the mimic octopus and the blister beetle, and the strong anthropic principle is accessible to anyone bright enough to be interested.

When Charles Darwin finished The Origin of Species, he thought that he had explained every clue but one. Though his theory could explain many facts, Darwin knew that there was a significant event in the history of life that his theory did not explain. During this event, the "Cambrian explosion", many animals suddenly appeared in the fossil record without apparent ancestors in earlier layers of rock. In Darwin's Doubt, Stephen C. Meyer tells the story of the mystery surrounding this explosion of animal 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.
