What is the difference between a nebula, quasar and red giant?

A nebula is a cloud of gas that surrounds a star that has exploded in a supernova. So it is essentially the remnants of a star that has died. A quasar is an extremely active black hole in the centre of a galaxy that spews out EM radiation. A red giant is a star that has reached the end of the main phase the envelope of the star is inflated which is what makes them giant.

Study smarter, learn faster without working harder

I spent a lot of my class time in secondary school being bored and restless. I was NOT a model student. Sitting in a class was always so boring to me. Then I discovered fun ways of making the lessons interesting when I attended the Mind Olympics in Earls Court. The 'mind athletes' at this event learned how to use their brains like a musical instrument. Learning and memorising facts easily like picking up feathers. Ever since that time I have been learning many subjects and showing other students how to enjoy their subjects while find better ways to get the results they want.
