Latest Space colonization Stories
When a planet absorbs too much solar radiation, its atmosphere reaches a tipping point - overheating, boiling its oceans and filling with steam. This 'runaway greenhouse' effect results is an uninhabitable world much like Venus.
‘Starship Congress’ Convenes With Scientists, Researchers This August in Tx; Eve Online, Ouya, Unity3d Among Sponsors of 1st Interstellar Science Summit Dallas,
This weekend, BBC News and Imperial College London will treat BBC viewers to a five-part television series depicting how a manned mission to Mars might unfold.
According to a new study published in the journal Astrobiology, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars.
The hunt is on for planets that, like Earth, have the conditions necessary for life to survive on their surfaces. But what exactly are scientists looking for? Earlier this week, NASA officials shed a little light on precisely what conditions they are seeking on worlds located beyond our solar system.
According to a new study from the University of Chicago and Northwestern University, the influence of cloud behavior on climate doubles the number of potentially habitable planets orbiting the most common type of stars in the universe, red dwarfs.
About 75 percent of the main sequence stars in our galaxy are classified as red dwarf stars and they represent an exciting population to study in the search for life beyond Earth.
Two university researchers say environmental restrictions have become unnecessarily restrictive and expensive—on Mars.
Astronomers have discovered a record-breaking planetary system with at least six planets orbiting its host star, of which three are super-earths and lie within the habitable zone.
Astronomers have determined that white dwarfs cool more slowly in the early stages of their life than models have previously predicted.
Ad Astra is a quarterly-published journal of the National Space Society (NSS). The name “ad astra” means “to the stars.” The journal was established following the merger of the L5 Society and the National Space Institute, which formed the NSS in 1987. The NSS is a non-profit aerospace advocacy and educational institution based in Washington DC. On November 28, 2007, the NSS announced MM Publishing Inc. as the newest publisher of Ad Astra. MM Publishing officially took on the role...
Terraforming -- Terraforming (literally, "Earth-shaping") is the process of modifying a planet, moon or other body to a more habitable atmosphere, temperature or ecology. The term was first used in a science fiction novel, 'Seetee Shock' (1940?) by Jack Williamson, but the actual concept is older than that. An example in fiction is 'First and Last Men' by Olaf Stapledon in which Venus is modified, after a long and destructive war with the original inhabitants, who naturally object to the...
