In the vast expanse of the cosmos, where stars twinkle in the night sky and galaxies swirl in the abyss, a remarkable dance of light and matter unfolds—a dance that has captivated the human imagination for centuries. This dance, illuminated by the science of spectroscopy, is what this book seeks to explore and explain. Spectroscopy, the study of the interaction between matter and electromagnetic radiation, may sound complex and esoteric, but at its heart lies a simple and profound idea: The colors of light can reveal the secrets of the universe.

In the vast expanse of the universe, where the night sky reveals countless stars, planets, and galaxies, the pursuit of knowledge knows no bounds. Among the many tools at the disposal of astronomers and astrophysicists, photometry stands as a beacon of precision and insight. This book, Photometry: Science, Sensitivity, and Its Connection to Astronomy, is your guided journey into the fascinating world of measuring and interpreting light in the cosmos.

O tempo não é um conceito abstrato. É uma substância material que ocupa todo o universo e se deforma, vibra, oscila. De Newton a Einstein, de Planck ao relógio cósmico, foi protagonista de metamorfoses vertiginosas, fascinantes e monstruosas. O tempo flui? Ou está parado? E como é medido? Como a gravidade o retarda? E como os buracos negros conseguem pará-lo? Sempre vivemos no tempo, que, no entanto, não é eterno.

Qual è il futuro dell’uomo nell’universo? Siamo soli nel cosmo? Esistono altre Terre che l’umanità può colonizzare? Queste sono solo alcune delle domande a cui Giovanni Covone, professore di astrofisica, cerca di dare risposta puntando lo sguardo in alto, verso il cielo e le stelle. Perché la storia della ricerca astronomica è antica quanto l’uomo stesso, dai primi, rudimentali eppure brillanti tentativi di studiare le stelle a occhio nudo, fino alle ultime missioni spaziali, svolte con l’ausilio di enormi, modernissimi telescopi.

Vorwärts in die Vergangenheit. Weiße Löcher sind das Gegenteil von Schwarzen Löchern – sie sind vermutlich ihre Abkömmlinge. Die einen ziehen alle Materie unwiderstehlich in sich hinein, die anderen geben ihre Information wieder frei. Sie sind ein weiteres großes Rätsel der Kosmologie, und noch gibt es keinen Beweis ihrer Existenz. Einsteins Gleichungen lassen sie aber vermuten, und mit Carlo Rovellis Quantentheorie sind Weiße Löcher theoretisch darstellbar.

In Into the Unknown, astrophysicist Kelsey Johnson takes us to the edge of scientific understanding about the universe: What caused the Big Bang? What happens inside black holes? Are there other dimensions? She doesn’t just celebrate what we know but rather what we don’t, and asks what it means if we never find that knowledge. Exploring the convergence of science, philosophy, and theology, Johnson argues we must reckon with possibilities—including those that may be beyond human comprehension.

The James Webb Space Telescope is transforming the universe right before our eyes—and here, for the first time, is the inside account of how the mission originated, how it performs its miracles of science, and what its revolutionary images are revealing. Pillars of Creation tells the story of one of the greatest scientific achievements in the history of civilization, a $10 billion instrument with a staggeringly ambitious goal: unlocking the secrets of the cosmos.

Set in a revolutionary era of physics and science when a series of rapid-fire discoveries was upending our understanding of the universe, Splinters of Infinity by Mark Wolverton tells a little-known story: the tale of two of America's foremost physicists, Robert Millikan (1868-1953) and Arthur Compton (1892-1962), who found themselves locked in an intense, often deeply personal, conflict about cosmic rays.

"Universe Deciphered" invites listeners on a transformative journey through the cosmos, uncovering the most profound insights that astronomy has to offer. Bridging the gap between celestial wonder and scientific understanding, this compendium illuminates the mysteries and marvels of the universe through 100 pivotal discoveries. From the early observations of Galileo to the latest findings from space telescopes, "Universe Deciphered" chronicles the advancements that have expanded our knowledge and reshaped our perspective of the cosmos.

Pillars of Creation: Is a poem based around the rekindling of interest in them from the the Hubble Space Telescope in 1995.

In The Allure of the Multiverse, physicist Paul Halpern tells the epic story of how science became besotted with the multiverse, and the controversies that ensued. The questions that brought scientists to this point are big and deep: Is reality such that anything can happen, must happen? How does quantum mechanics "choose" the outcomes of its apparently random processes? And why is the universe habitable? Each question quickly leads to the multiverse.

Trous noirs, exoplanètes, les nouvelles techniques d'observation en astronomie ont permis d'extraordinaires découvertes. Une résolution beaucoup plus fine des images. Durant les dernières décennies, de nouveaux instruments d'observation situés sur Terre et dans l'espace ont, grâce à des progrès dans la résolution des images, donné lieu à des découvertes extraordinaires. Trous noirs et exoplanètes : des découvertes extraordinaires. Pierre Léna décrit ici ces innovations instrumentales et s'attarde sur deux découvertes majeures récentes.

L'Univers a-t-il une forme ? En s'intéressant au contenu visible de l'univers, aux planètes, aux étoiles et aux galaxies, on oublie parfois le contenant invisible, l'espace lui même. Celui-ci est-il un simple réceptacle passif ? A-t-il une forme, une structure ? Est-il fini ou infini ? Est-il courbe, plat, lisse ou grumeleux ?Une présentation des différents modèles cosmologiques. Jean-Pierre Luminet présente les grandes lignes des démarches cosmologiques actuelles et des formes possibles de l'univers.

Jean Pierre Luminet nous invite à un voyage fascinant qui, de la Grèce antique à nos jours, explore les métamorphoses de l'infini. De manière toujours accessible, il aborde l'infini de l'espace avec la cosmologie, celui des nombres avec les mathématiques et les mystères de l'infiniment petit dans la matière avec la physique quantique.

The BBC presenter of 'Sky at Night', and Gresham Professor of Astronomy, Chris Lintott, takes us on an astonishing tour of bizarre accidents, big characters, and human error to tell the story of some of the most important astronomical events of the past hundred years.

Os grandes mistérios e maravilhas do céu noturno sempre nos fascinaram, intrigaram e divertiram, desde os primeiros passos na Terra. Hoje, continuamos nos esforçando para entender o nosso lugar no cosmos. 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, e essa busca nos proporciona uma valiosa compreensão da vastidão e das infinitas possibilidades do espaço universal que ainda estamos por descobrir.

This book gets into the history of the JWST, the instruments it carries, new observations, and ideas of what these anomalies mean. We review some of the most important observations made to date, and finally, some theories of how to explain these incredible views of the early reality of the Universe.

A Mysterious Universe introduces the fundamental laws of quantum mechanics, theory of relativity, and cosmology to a novice in simple language. This concise book deals with deep issues related to the mysteries of modern physics.

Scientists tell us that ninety-six percent of the universe is unexplained dark matter and dark energy. Also, they admit that no unifying “theory of everything” exists in physics. This shaky foundation is the basis of modern thinking about the cosmos and Earth’s place in it. Something big seems to be missing. Thus, we’re left with no choice but to question the “consensus” cosmological model. Are we really flying through space on a spinning ball within an expanding universe, while free-falling around the Sun—all as a consequence of a “Big Bang” that supposedly occurred 13.8 billion years ago?

Attend to these words gentle soul, herein ye shall find a two-part alchemical discourse concerning the purity and veracity of scientific thought, separating the 'ugly truth' (science conspiracies) from the 'beautiful truth' (the secret art of Alchemy). Part One takes aim at the post-modern secular worldview of Scientific Materialism or Scientism, rebuking and revealing the fatal flaws inherent in its core beliefs and cosmology, as well as the various conspiracies and occult shenanigans underlying physics, chemistry and medicine.
