It is said that it was built as a result of the magic of the wizard of Arthurian legend, Merlin, who transported the massive stones from Ireland.

It is possible that Stonehenges builders were practicing some form of early Bronze Age astronomy. (Photo by: Alan Dyer /VW PICS/Universal Images Group via Getty Images). We view the system about three degrees above the stars orbital plane, so they undergo mutual eclipses, but neither is ever completely covered up by its partner. The constant change is due to the slightly unsteady rotation of Earth. Thuban, also called Alpha Draconis, is located about 270 light-years away in the northern constellation Draco.Credit: NASA's Goddard Space Flight Center/Chris Smith (USRA)Watch this video on the NASA.gov Video YouTube channel. On midsummers day, the sun rises just to the left of the Heel Stone, an outlying stone to the north-east of the monument, in the center of the stone circle.

Its companion, which is five times fainter, is most likely half the primarys size and 40% hotter than the Sun. In this case, the high precision TESS data can be used to help constrain fundamental stellar parameters at a level we've never before achieved, said the NASA scientist, whose forefathers in the ancient world regarded eclipses as powerful omens that foretold death and destruction. And until were 100% comfortable issuing that new certificate of operation, we will not do so.. When the pyramids of Giza were being built, Thuban served as the North Star.

At that time, it appeared as the North Star, the one closest to the northern pole of Earth's spin axis, the point around which all of the other stars appear to turn in their nightly motion. Using TESS, the researchers were able to track changes in the stellar pair's brightness for 27 days at a time, revealing that Thuban and its companion are among the brightest "eclipsing binaries" pairs of stars that pass in front of one another.
