O século 20 foi palco de importantes e assombrosas descobertas sobre o nosso próprio planeta, o sistema solar, as estrelas e as galáxias. Contudo, ainda buscamos respostas para inúmeras questões – O que é matéria escura? Estamos sozinhos no universo? É possível viajar no tempo? –, e essa busca nos proporciona uma valiosa compreensão da vastidão e das infinitas possibilidades do espaço universal que ainda estamos por descobrir.
O universo, considerando-se a sua imensidão, pode ser assustador, mas neste livro de fácil compreensão embarcamos numa viagem incrível através de todas as descobertas astronômicas fundamentais, desde as resultantes de crenças de civilizações antigas até as oriundas de pioneiras e recentes observações das ondas gravitacionais, previstas por Einstein mais de 100 anos atrás. Nunca houve ocasião melhor para começar a entender os mistérios do universo, e este guia essencial do cosmos é o melhor ponto de partida!
'A gripping exploration of one of the most fundamental, but also perplexing aspects of existence.' PROF. LEWIS DARTNELL, author of Origins

Perfect for readers of Carlo Rovelli and anyone fascinated by space and the universe, this is a must-read for those short on time, but not curiosity.
Un libro apasionante sobre todo aquello que siempre quisiste saber acerca del universo, desde el Big Bang hasta los más recientes descubrimientos de astronomía.
¿Quién no se ha sentido fascinado por las maravillas del cielo nocturno? Desde que los primeros humanos caminan sobre la tierra, hemos intentado comprender nuestro lugar en el cosmos. ¿Qué es la materia oscura? ¿Estamos solos en el universo? ¿Es posible viajar en el tiempo? Preguntas como estas nos proporcionan una visión fascinante de las infinitas posibilidades del espacio, aún por descifrar.
La inmensidad del universo puede resultar intimidante. Por eso, de una manera accesible, este libro nos propone un increíble viaje a través de los descubrimientos astronómicos más importantes, desde las creencias de las civilizaciones antiguas hasta los hallazgos más recientes y revolucionarios.
Comenzando con los primeros astrónomos, desde Ptolomeo hasta Newton, esta travesía parte desde la Tierra, el Sol y la Luna y se dirige cada vez más lejos de casa, cubriendo el Sistema Solar, las estrellas y las galaxias, para llegar finalmente al borde del universo y sus misterios: el Big Bang, la inflación cósmica y la energía oscura. Esta guía es el punto de partida perfecto para un viaje de descubrimiento del espacio y de nuestro lugar en él.

A fascinating and comprehensive guide to the sun - our home star - which remains the greatest mystery in the solar system, and why understanding it is pivotal to our future existence here on Earth.
In 1869, a great mystery was born. As astronomers observed a total solar eclipse, for the first time they saw the faint glow of the solar corona, the sun's outer atmosphere. Measurements of a previously unknown wavelength that made up this solar light sparked hot debate among scientists, but it was another sixty years before they discovered that this wavelength was in fact iron being burned at a staggering 3 million degrees Celsius. With the sun's surface only 6,000 degrees, this shouldn't be possible. What we now knew about the sun appeared to defy the laws of physics - and nature.
But as well as being shrouded in intriguing mystery, the unpredictable nature of the sun's corona poses a serious threat to our life here on earth - the destructive potential of solar storms, caused by solar material travelling out into space at around 1 million miles an hour, is huge. Remaining beyond our reach until now, a new generation of ambitious solar missions are currently travelling closer to the sun than any previous spacecraft in history. As we enter this unprecedented era of heliophysics, there has never been a better time to get to grips with the workings of our home star.

Since the earliest humans walked the earth, the vast mysteries and wonders of the night sky have fascinated and beguiled us, as we've struggled to understand our place in the cosmos.
Even after the last century, which saw important and startling discoveries about our own planet, our solar system and the stars and galaxies beyond, there remain more questions than answers. But those questions - What is dark matter? Are we alone in the universe? Is time travel possible? - provide a fascinating insight into the vastness and infinite possibilities of space that we're yet to determine.
The sheer scale of the universe can be intimidating, but in this easily digestible book we embark on an incredible journey through all the essential astronomical discoveries, from the beliefs of ancient civilizations, through to the recent groundbreaking observations of the gravitational waves predicted by Einstein over 100 years ago. There's never been a better time to get to grips with the universe and this essential guide to the cosmos is the perfect place to start!
