Sky Tonight—April 1, Use Big Dipper to find Polaris

Sky Tonight—April 1, Use Big Dipper to find Polaris and Little Dipper

Courtesy of EarthSky A Clear Voice for Science Visit EarthSky at www.EarthSky.org Here is the view northward on April evenings. At present the Big Dipper is high in the north. Notice the two outer stars in the bowl of the Big Dipper. These two stars – called Duhbe and Merak – always point to Polaris, the North Star. Polaris is special because it always stays in the same spot in the northern sky. It is the star around which the entire northern sky appears to turn. That is because ... Full Story

EarthSky Tonight—October 16, See Cassiopeia and Big Dipper on autumn evenings

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org On October evenings, the Big Dipper resides rather low in the northwest sky, and the W or M-shape constellation Cassiopeia the Queen sits on her throne in the upper northeast sky. These two star formations are like riders on opposite side of a Ferris Wheel. They spin around Polaris, the North Star, once a day. As one rises upward, the other plunges downward – and vice versa. As evening deepens into late night, the Big ... Full Story

EarthSky Tonight—September 7,  Use Big Dipper to find Polaris, the North Star

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight’s chart shows the Polaris, the Big and Little Dippers for a September evening. Notice that a line from the two outermost stars in the bowl of the Big Dipper point to Polaris, the North Star. Also notice that Polaris marks the tip of the handle of the Little Dipper. Bright star in east? Might be planet Jupiter, nearly at its closest since 1951. The Big Dipper swings full circle (360 degrees) around Polaris in ... Full Story

Earthsky Tonight—August 3, Dipper points to Polaris,

Earthsky Tonight—August 3, Dipper points to Polaris, plus see Mizar and Alcor

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The two outer stars in the bowl of the Big Dipper – Dubhe and Merak – always point to Polaris, the North Star. To find this Dipper at this time of year, look toward the northwest in the evening. Once you have found it – after locating Polaris – look more carefully at the second star from the end of the Big Dipper’s handle. If your sky is dark enough, and your eyesight is good, you will see that this star, ... Full Story

Earthsky Tonight—April 7, 2010: Kochab and Pherkad in the Little Dipper

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org If you draw an imaginary line between the two outer stars in the bowl of the Big Dipper – and extend that line northward on the sky’s dome – you’ll come to Polaris, the North Star. Polaris marks the end of the handle of the Little Dipper, which is fainter and looks less like a dipper than the Big Dipper. Polaris is special because Earth’s northern axis nearly points to it. Polaris is less than a degree away ... Full Story

Earthsky Tonight — April 6, 2010: Use Big Dipper to find Polaris and Little Dipper

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Here is the view northward on April evenings. Now the Big Dipper is high in the north. Notice the two outer stars in the bowl of the Big Dipper. These two stars – called Duhbe and Merak – always point to Polaris, the North Star. Polaris is special because it always stays in the same spot in the northern sky. It is the star around which the entire northern sky appears to turn. That is because Polaris is ... Full Story

Earthsky Tonight — March 4, 2010: Recognize the Big Dipper … and Little Dipper

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org We received a question about the Big and Little Dippers. “How can I locate both Ursa Minor and Ursa Major? I am seeing one of them in the sky . . . but cannot tell which one and where the other one is.” The answer is that, if you are seeing only one dipper, it is probably the Big Dipper in the constellation Ursa Major. This constellation, also called the Greater Bear, contains the Big Dipper asterism that is ... Full Story

Earthsky Tonight — March 3, 2010: Use the Big Dipper to locate Polaris

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org At one time, sailors’ livelihoods and survival depended on their lucky stars – most especially, the pointer stars of the Big Dipper. Drawing a line through the two outer stars of the bowl faithfully points to Polaris, the North Star. Polaris is not the brightest star in the sky, as is commonly believed. It is a moderately bright second magnitude star, radiant enough to be easily seen – even on a moonlit night. ... Full Story

Earthsky Tonight, February 12, 2010: Use Big Dipper’s Pointers to find Polaris

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org If you can find the Big Dipper in the northern sky in mid to late evening tonight, you can find the North Star, Polaris. The Big Dipper is not a constellation. Instead, it is an asterism, just a recognizable pattern of stars on the sky’s dome. It is part of the constellation Ursa Major, the Greater Bear. A well-known trick for finding the North Star, or Polaris, is that the two outermost stars in the bowl of ... Full Story
