Science DiscussionsThe declaration of Driver and his team about more dust surrounding galaxies will most likely force astronomers to alter calculations that they make with regards to the intrinsic brightness of galaxies and other celestial bodies. In fact, Driver stated, “This is a strong, clear-cut result. We've really got to take dust seriously and we've got to make large adjustments to our magnitude calculations." The findings within the Driver research study appears in the May 10, 2008 issue of the Astrophysical Journal Letters. |
