EarthSky Tonight—October 17,  Solar system’s outermost planet near moon

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Do not expect to see Neptune, even though it is close to the moon tonight. Neptune, the 8th planet out from the sun, is the only solar system planet that you absolutely cannot see with the unaided eye. Pluto is not visible to the unaided eye, either, but in 2006, this distant world was reclassified – some say demoted – to “dwarf planet” status. Because of the moonlit glare, you probably will not even see the rather faint ... 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 Dipper ... Full Story

Paula wrote, "This morning two of us got up early. We found a pulsing star straight down the sky below Orion’s Belt. It was pulsing the colors of green, yellow, blue and red like a strobe light.

We got this question: "I’m having a difficult time being able to recognize the constellations of the Zodiac . . . do you have any advice?" Yes . . . we can recommend a few things.

EarthSky Tonight—October 13, Moon is waxing, but still low in sky

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Diana from Potsdam, NY asked, "Why are the evening crescent and the first quarter moon always so low in the autumn evening sky?" The answer is that, as seen from our northern hemisphere, the ecliptic – the pathway of the moon and planets – sinks very low in the southern sky on autumn evenings. That is why the waxing crescent moon and the first quarter moon always loom low in the sky in September and October, as seen from this ... Full Story

Still, many have asked about a bright star – not as bright as Jupiter, but still very bright and twinkling very actively – in the west after sunset. Jim wrote, ... Full Story
