ed quasar observations, astronomers had to wait for Hubble's capabilities to show the host galaxies clearly enough for astronomers to begin to classify their shapes.2. Interactions between galaxies, either through direct collisions or near encounters, can be important in turning on a quasar, by dumping fuel onto a black hole. However some quasars look unperturbed, so there may be other, more subtle mechanisms for feeding the black hole. Some of the galaxies we observed don't appear to know they have a quasar in their core.3. Quasars that are radio quiet are often in elliptical galaxies, not always in spiral galaxies, as previously believed. Advanced instruments planned for Hubble should also help pin down more details. The Near Infrared Camera and Multi-Object Spectrometer (NICMOS), to be installed in 1997, and the Advanced Camera, to be installed in 1999, will have coronagraphic devices which will block out the glare of a quasar, allowing astronomers to see closer into a galaxy's nucleus. By viewing galactic structures in infrared light , the NICMOS should be able to provide important new details about the host galaxies of quasars. The continued study of quasars and the information that it will provide us with may help us to develop a better understanding of space and how we fit in to this great puzzle....
