In our syllabus,The last chapter of Physics Second paper is "ASTRONOMY".I have read that chapter from many text books of HSC and I figured out that that most the books are filled with incorrect information.So this topic become confusing to the students.Unfortuately,they show no interest in the most interesting chapter of their syllabus.So,this thread is for those students who are not understanding any specific concept of Astronomy.Ask question by giving question number .Anyone can post questions.
