Showing results for "six" in Astronomy & Space Science

There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "Big Bang", determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned", there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws. 

Lost in the wilderness of The Yellowstone for over a month, nearly dying of starvation and wild animal attack, despairing of ever finding his way out. Here are six relatively unknown early pieces about the U.S.A.’s first national park. The first is a U.S. Geological booklet about initial exploration and Congress’s institution of the park. The next two are articles from Scribner’s Monthly, 1871, a very popular magazine of the time, describing the park’s features (vol 2 #1 pp 1-17 and vol 2 #2 pp 113-128) . The fourth piece is a narrative by the leader of the exploratory expedition ...

The Scientific American may be the oldest continuously published periodical in the United States, having launched its first publication in 1845. It has been a mainstay of popular science with in depth articles across a broad spectrum of scientific fields. In this supplement are short articles ranging through such topics as Camellias, Experiments in Memory, The Chemical Action of Light, and longer articles on the Gas Engine, and Optical Telegraphy. - Summary by Larry Wilson

There is a lot of interest these days in space exploration. After 50 years, we are looking at going back to the Moon to build a base and planning early for a manned trip to Mars. After that, further exploration and settlement of the Solar System will be on the table. One of the main limiting factors for all of this space exploration are the types of rockets and rocket engines available to get there.

Er vi alene i universet - eller findes der liv blandt stjernerne? Tag med astrofysiker Alexander Rathcke på en rejse gennem kosmos: Fra Big Bang og stjernestøv til Jordens tidligste liv og livets og planetens samudvikling, videre til Mars’ hemmeligheder og fjerne exoplaneter omkring andre stjerner. Sammen med nogle af Danmarks førende forskere undersøger han forudsætningerne for, at liv kan opstå, hvor udbredte betingelserne er, og hvad vi kan lære af de nyeste opdagelser. Alt sammen i et forsøg på at besvare spørgsmålet: Er vi alene? Podcasten er produceret med støtte fra ...
