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.

There has always been a lot of conflict and contention between religion and science, arguably since the beginning of human abstract thought. Everyone has an opinion on how the two interact, intermingle, or completely repel against each other. The Accidental Universe: The World You Thought You Knew is simply one man’s opinion written into a book.
“It does not do harm to the mystery to know a little about it. For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it?” -- Richard Feynman (1918 – 1988)
