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...

We investigate star formation in the Sc(s) II-III galaxy M33 by analyzing eight prominent HII regions using multi-wavelength data from the Spitzer Space Telescope and optical imagery. Results indicate that dust emission is a compact tracer of high-mass star formation, while PAH and H-alpha emissions decline more slowly with galactocentric radius.
Just like the dust that stubbornly besmirches your computer monitor, bookcase, and ancestral credenza, cosmic dust is now recognized to have a multiplicity of origins. For decades, astronomers thought that aging red giant stars produced most of the dust responsible for obscuring and reddening our views of nebulae and more distant stars ...
In this essay, I argue in support of teaching the Earth & space sciences together, so that students can attain a more holistic understanding of their planetary environment, how it came to be, and where it is headed. Such teaching (and teachers) should receive the same priority as in the teaching of physics, chemistry, and biology.
We’ve all shown Saturn to someone, or perhaps have shared a clear view of a bright globular, say, M13, with someone who hasn’t seen such a thing before. In these and similar cases, the sheer beauty of the thing is the whole point; any impressive facts are secondary.
