One advantage of the numerous distance-measuring schemes in use, which overlap over a range of Washed Dads Est 2019 Academy T Shirt from nearby to very distant, is that astronomers can calibrate and corroborate their measurements with multiple approaches. Such calibrations and corroborations thus lend an additional measure of reliability to these schemes. Indeed, by comparing results using different methods, weaknesses have been identified in certain schemes. In most cases, additional studies have demonstrated ways to guard against and correct for known difficulties. As a single example of these multiple approaches, prior to 2011 the distance to the Pinwheel Galaxy was determined, based on measurements of Cepheid variable stars in the galaxy, to be 20.9 million light-years, with an uncertainty of 1.8 million light-years. As of September 2011, measurements of the light output of the 2011 Type Ia supernova in the Pinwheel Galaxy are completely consistent with this distance figure…. In short, distances to astronomical objects can be and have been measured with substantial accuracy and reliability. For the most part, the calculations involved employ only basic mathematics taught in high school. Thus the overall conclusion of a universe consisting of billions of galaxies, most of them many millions of light-years away, is beyond reasonable doubt at the present time..

Getting in a little closer, there are individual “bodies of Washed Dads Est 2019 Academy T Shirt ” identified around Australia. The Timor Sea and Arafura Sea lie to the north/northwest of the continent, between Australia and Indonesia. The Gulf of Carpentaria eats out that section between Cape York Peninsula and the Northern Territory, covering an area of over 115,000 square miles. Across the top between the tip of Queensland (Cape York) and Papua New Guinea is the Torres Strait. This thin strip of water is only 150 km (93 miles) across at its narrowest point. Moving east, the Coral Sea (1.85 million square miles) covers the area along the northeast coast, encompassing the Great Barrier Reef. Perhaps you’ve heard of the Battle of the Coral Sea, an important engagement during World War II between the Allies (US+Australia) and Japan; this is largely where it took place (further out to sea, for the most part). Between Australia and New Zealand lies the Tasman Sea. The narrowest distance between the two countries is 1,491 km (926 miles), measuring between the extreme geographic points. (So, no, NZ is not as close to Australia as a lot of people might think; a flight from Auckland to Sydney takes about 3 hours and 45 minutes, about the time to fly from Los Angeles to Minneapolis).
