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 ...
To form a solar system, the literature says that in a simulation like this we can ignore the gravity of the Sun and just concentrate on the interaction of the objects in the protoplanetary disk.The gas, dust and other objects rotate around the forming Sun in Keplerian orbital motion...
Astronomy encompasses the fields of Planetary Science (including Earth as a planet), Heliophysics, Astrophysics, Astrochemistry, Astrobiology, Cosmology, and Cosmogony – the study of cosmic origins. Astronomy, in turn, is informed by the core sciences of Physics, Chemistry, and Biology. It both depends upon and helps to advance technological innovation...

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.

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.
