Jedidah Isler, observational astrophysicist, told TED users about our wonderful universe. She said that everything we can see in galaxy comprised of billions of stars. She studied some most of the exotic objects in our galaxy. Supermassive, hyperactive black hole which had 10 billion times larger than the mass of the sun had captivated her. These gigantic black hole are also devouring material 1000 times larger than human average 'black hole'. These characteristics make them quasars and at the same time they produce particle streams namely jets that are moving at 99.99 percent of speed of light pointed directly at the earth. All of these called blazing quasars and become the universe's most efficient particle accelerators transporting incredible amount of energy throughout a galaxy. She was then curious about how the white blobs form and the relationship between the jet and the accretion disc material. She compared variations between gamma ray data and visible light data from year to year. The research shows that the blobs form much closer to the black hole.
