Available in PDF, EPUB and Kindle. Book excerpt: Los enigmas del Cosmos es un viaje de exploración a través de los grandes misterios astronómicos para los que la ciencia aún no ha obtenido una explicación, aportando al lector la clave de los grandes secretos que se guardan entre las estrellas. Aceptada la teoría del Big Bang para explicar nuestro origen, podría parecer que sabemos lo fundamental de nuestra realidad cósmica, pero lejos de ello astrónomos y cosmólogos trabajan en pleno siglo xxi ante el increíble reto de averiguar por qué más de un 80 por ciento del universo permanece perdido en forma de materia oscura que no podemos observar. La astronomía, la ciencia más antigua, continúa sin resolver sus grandes enigmas, como el de las extinciones masivas por grandes impactos cósmicos que sacuden periódicamente la Tierra. El suceso de Tunguska, un remoto lugar de Siberia donde, en 1908, cayó un gigantesco cuerpo celeste, mantiene intacto su misterio. Mientras, algunos científicos se preguntan si el Sol podría tener una estrella oscura como compañera (Némesis), con alteraciones que podrían favorecer episodios de extinción a intervalos de millones de años. El planeta X, otro enigma que dura más de un siglo, ha recobrado la atención de la ciencia en los últimos años en busca de un mundo de gran tamaño en los confines del Sistema Solar. Y sigue en el aire la cuestión fundamental, la que nos mueve a preguntarnos si estamos solos en el Universo. Las últimas misiones espaciales han aportado nuevos y prometedores escenarios en la búsqueda de vida merced al inesperado hallazgo de presumibles océanos bajo la helada superficie de lugares tan aparentemente hostiles como Plutón y las lunas Europa y Encélado. En los últimos años, además, se han descubierto miles de exoplanetas que orbitan alrededor de estrellas diferentes al Sol, por lo que las expectativas se multiplican. Paralelamente, el conocimiento de organismos extremófilos y conceptos como la panspermia parecen abocarnos a una nueva perspectiva en la que la vida, en sus formas más elementales, podría estar mucho más extendida en el Universo de lo que se pensaba hace tan sólo medio siglo. En este viaje el lector también encontrará una selección de más de sesenta interesantes imágenes, incluidas las de las últimas misiones espaciales enviadas a Marte, Júpiter, Saturno y Plutón, como las de las sondas Juno, Cassini/Huygens y New Horizons. El autor nos guía en un viaje que va del corazón del Sistema Solar al espacio más allá de sus límites. Que estos secretos cósmicos lleguen a desvelarse algún día sigue siendo, naturalmente, un enigma.

Download or read book Mercury Rising John Glenn John Kennedy and the New Battleground of the Cold War written by Jeff Shesol and published by W. W. Norton & Company. This book was released on 2021-06-01 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: A riveting history of the epic orbital flight that put America back into the space race. If the United States couldn’t catch up to the Soviets in space, how could it compete with them on Earth? That was the question facing John F. Kennedy at the height of the Cold War—a perilous time when the Soviet Union built the wall in Berlin, tested nuclear bombs more destructive than any in history, and beat the United States to every major milestone in space. The race to the heavens seemed a race for survival—and America was losing. On February 20, 1962, when John Glenn blasted into orbit aboard Friendship 7, his mission was not only to circle the planet; it was to calm the fears of the free world and renew America’s sense of self-belief. Mercury Rising re-creates the tension and excitement of a flight that shifted the momentum of the space race and put the United States on the path to the moon. Drawing on new archival sources, personal interviews, and previously unpublished notes by Glenn himself, Mercury Rising reveals how the astronaut’s heroics lifted the nation’s hopes in what Kennedy called the "hour of maximum danger."
