It is tempting to say that any well-educated person should know what it takes to be scientifically literate. But what does scientific literacy really involve? Given that scientific literacy is a key goal of most science education standards and frameworks, considerable ink has been dedicated to utilizing the term in pedagogical papers.
Africa’s astronomical debut has come at an opportune time, as a multitude of facilities and projects have taken root across the continent in the service of astronomical questing.
If we ever make contact with an alien civilization, how will we understand what they’re saying? That’s the question that preoccupies John Elliott of...
By now, you have probably read or heard that our polluting ways have reached a critical point, where Earth is rapidly approaching total failure as a planet. Perhaps you have wondered how we humans could have managed to do so much damage in so little time.
Permanent settlements in space will require forms of localized government that are likely to differ from contemporary models of political order. This article thus asks a provocative question associated with the empirical record of human colonization and settlement in prior eras: What sort of authoritarian governance is most likely to form in human space settlements during the medium term?
...What we have come to appreciate is the seminal role played by clustered star formation in driving the physical and chemical evolution of the galaxies that host these stellar nurseries. Such concentrated sites of newborn stars along with their nebular environs constitute what are known as galactic ecosystems. These energized realms represent vital “crucibles” for growing the chemical complexity that is necessary for biotic processes.
If the Big Bang theory is correct, how fast is the universe expanding? Astronomers are facing a troubling disconnect between different methods used to measure the expansion rate, known as the Hubble constant. The two methods are giving similar but slightly different rates. Either one method is providing inaccurate results, or there is some kind of unknown physics operating in the universe.
