What observation in astronomy, made AFTER the discovery of quasars, was a big help to astronomersin figuring out what quasars really were?3EO the discovery that the Milky Way Galaxy has a black hole at the center with enough mass for 4 million SunsO the understanding that most stars become white dwarfs when they die and white dwarfs are much smaller thanmain-sequence starsDO the discovery of exoplanets (planets orbiting other stars) throughout the GalaxyO the discovery that the galaxies mostly show a red shiftO the discovery of Herbig-Haro objects around newly forming stars4F3C$449RFQ SearchDII%5VF5TGaV6AF6YB*HF7&PrtScnUNFB*008JHome-F99EndKMF10OC

A quasar is an enormous object same like star. It also shines very brightly. It sends out radio…

Your friends are talking about Olber's Paradox: Friend 1: When the universe was quite young, it was also quite small, and therefore light was trapped inside the universe. This is why we don't see light from the edge of the universe in every direction. Friend 2: No, Olber's Paradox describes only light from stars, not from galaxies, and why you can't use light from distant stars to see at night. Friend 3: You're both right and you're both wrong. The paradox concerns itself with the expansion of the universe, and explains why light from the early universe was able to be released. Are any of them right, in part or in whole?
An astronomer in an imaginary Universe observes a small patch of the sky (0.005% of the total) with very deep observations and finds one million galaxies. How many galaxies can they estimate to be present in the whole Universe? 10 billion 20 billion 50 billion O 70 billion
The Milky Way grew through merging with many smaller galaxies. What are the observational signatures of this process? O The motion of old stars in the bulge and halo of our galaxy are randomly orientated, meaning they were formed from collisions of small, accreted, galaxies all on different paths. O The ordered motion of the bulge / halo stars means that they came from many objects. The random motions of stars in the disk means it was formed from collisions of small, accreted, galaxies. O The motion of young stars in the disk are all in the same direction, meaning they came in as seperate objects.
Distance Based on the graph above, the expansion rate of galaxies near us is than galaxies that are farther away. O faster slower O the same rate Velocity
If Jim could drive a Jetson's flying car at a constant speed of 330 km/hr across oceans and space, approximately how long (in millions of years, in 106 years) would he take to drive to a nearby star that is 8.7 light-years away? Use 9.461 × 1012 km/light-year and 8766 hours per year (365.25 days).
How can we determine the existence of something we can't see? What is the evidence of dark matter and dark energy? How can we learn more about this phenomena?
