Astronomy

Menschen fliegen ins Weltall – das scheint uns inzwischen normal. In dieser Ausgabe von „Erzähl mir alles: Physik" beleuchten wir die Raumfahrt von Vergangenheit bis Zukunft, und von der kosmischen Nachbarschaft bis in die Ferne. Touristische Flüge an die Grenze des Weltalls, Langzeit-Aufenthalte auf Raumstationen, neue Flüge zum Mond oder Ende sogar eine Reise zu den Sternen: Egal, wohin es gehen soll, ohne Physik geht nichts!

COMO O UNIVERSO SURGIU? QUAL SERÁ SEU DESTINO? O QUE HÁ NELE? Em O universo escuro, a astrofísica Larissa Santos convida o ouvinte a mergulhar nos maiores enigmas da cosmologia contemporânea: a matéria escura, a energia escura e os limites do conhecimento científico. Com linguagem acessível e, ao mesmo tempo, rigorosa, a autora percorre os fundamentos da física moderna e as descobertas que abalaram a forma como compreendemos o cosmos. Neste audiolivro, não há espaço para respostas fáceis.

Carl Edward Sagan (November 9, 1934-December 20, 1996), born in Brooklyn, NY, was an American astronomer and astrophysicist. His best-known scientific contribution was his research on the possibility of extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by exposure to light. The following is a lecture Sagan gave in 1977 during which he discussed life on earth and other planets.

Planet Earth has been a familiar concept for a mere fraction of recorded history. Until about the mid-1600s, most humans thought of Earth as immobile, likely either dim or simply invisible from the Moon or anywhere else in the heavens, and not (like the planets) participating in what Galileo...

The iron in your blood was forged in the nuclear furnace of a dying star. The gold in your jewelry was born in the collision of neutron stars so violent it sent ripples through spacetime itself. The carbon in your DNA survived a stellar explosion and a billion-year journey through space before becoming part of you. Born from Catastrophe reveals the extraordinary truth behind these statements: we are not just made of stardust, but of stardust created through the most violent events in the universe.
