![]() Viewers were to stand in line, picking up the things they wanted and proceeding to the cashier. The only downside to the food was the price. There was a vast selection of dinner and snacks available at the snack bar. The concessions were very organized and clean. The organization and the ability to see two movies for the price of one ticket made the expensive cost seem not terrible. Because the experience and food exceeded my expectations, my party felt that the cost was worth it. This first made me hesitant to purchase things such as a food permit in order to bring in outside food. The tickets and food were essentially the same as if one was seeing a movie at Aksarben or Majestic Cinema. The cost of the Quasar Drive-In was slightly pricey. The website also gives clear information on how to buy tickets and food permits, which can also be purchased at the box office. Under the “FAQ” tab, I was able to find out information such as where I should park and when I should show up. The website is easy to function and gives clear information about the dos and don’ts of the drive-in. The website of the Quasar Drive-In provided a lot of information and answers most questions for those who are interested. The lower two panels progressively zoom out to show dust and gas structures on much larger scales.The Quasar Drive-In of Valley, Nebraska pays tribute to a classic family outing while also showing modern movies. The top panel zooms in to show the feeding black hole on a scale roughly the size of the solar system. Just remember that this picture might change over time as we learn more! These panels dissect one version of the current quasar model each cross-section is an edge-on view at a different zoom level. While the details are still up for debate, we can use current knowledge to paint a general picture of a quasar. Astronomers have to ferret out the details using other techniques, such as analyzing spectroscopy (spreading out the light by wavelength) or light curves (spreading out the light by its arrival time). Yet quasars often outshine their hosts.ĭespite their brilliance, quasars are so small and distant that even the most powerful telescope cannot resolve all the structures within a quasar. ![]() That dwarfs in comparison to its host galaxy the Milky Way for comparison is roughly 100,000 light- years across. The size of a quasar accretion disk, which scales with the mass of its black hole, is typically a few light-days across. Farther out from the black hole, the prolific dust and gas glow at infrared wavelengths. Jets shooting out along the black hole’s poles emit everything from radio waves to X-rays. Visible and ultraviolet light come from the glowing disk of infalling material, while even hotter gas above the disk shines at X-ray energies. What Does a Quasar Look Like?Ī quasar is not only the feeding black hole itself, but the light-producing structures that surround it. The nearest quasar is Markarian 231, which lies about 600 million light-years from Earth. Supermassive black holes in nearby galaxies typically do not have that much gas available to them, so quasars are typically found in distant galaxies. The gas spirals around as it falls in, heating up in the process and emitting radiation across the electromagnetic spectrum. They reside in galaxies with plentiful gas supplies, perhaps supplied by a recent galaxy-galaxy collision, and they gorge on the inflowing material. Other dormant black holes occasionally shred an infalling star, making their presence known by the flare of radiation that ensues.īut quasars are a different breed of black hole. We know it’s there, though, from the orbits of stars around it. Our Milky Way’s behemoth weighs in at 4.3 million solar masses, but its starvation diet mutes all but faint flashes and flickers. In fact, almost every large galaxy hosts a black hole with the mass of millions to billions of Suns, and many of these black holes lurk in the dark. It’s a bit of a contradiction to call a black hole luminous black holes themselves are, of course, black. Now, the term is a catch-all for all feeding, and therefore luminous supermassive black holes, also often called active galactic nuclei. Quasar is short for quasi-stellar radio source, because astronomers first discovered quasars in 1963 as objects that looked like stars but emitted radio waves.
