The ecliptic is the Earth’s orbital plane projected outward onto the sphere of stars. The ecliptic is often shown on sky charts, because the moon and planets ... Full Story

Sky Tonight—December 28, Find a variable star in Lyra

Courtesy of EarthSky A Clear Voice for Science Visit EarthSky at www.EarthSky.org This evening, we zoom in on a variable star – a star whose brightness changes – near the star Vega in the small but distinctive constellation Lyra the Harp. Here is how to locate it. A dark sky brings out the four rather faint stars to the left of Vega. These stars form a parallelogram – a four-sided figure with its opposite sides equally long and parallel to one another. Three fingers at an arm ... Full Story

EarthSky Tonight—Nov 24,Venus getting brighter in the predawn sky

Courtesy of EarthSky A Clear Voice for Science Visit EarthSky at www.EarthSky.org The planet Venus – the most brilliant celestial object after the sun and moon – is getting brighter day by day in the November predawn sky. This dazzling world was in our evening sky earlier this year. However, it recently passed between earth and the sun, so that it now rises about 3 hours before sunrise as seen from mid-northern latitudes. Moreover, at middle latitudes south of the equator, Venus ... Full Story

EarthSky Tonight—September 1,  Venus, Mars, Spica meet in west after sunset early September

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The first few evenings of September 2010 present a celestial trio – the planets Venus and Mars, and the star Spica fitting within a circle that is smaller than 5 degrees in diameter. Because a typical binocular field spans about 5 degrees of sky, there is a good chance of seeing all three luminaries squeezing up together inside a single binocular field. All three should be bright enough to see with the unaided eye, if ... Full Story

As seen from North America, the threesome cozies up even more closely on ... Full Story

EarthSky Tonight—August 23, Venus points way to fainter Mars

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org How soon can you spot Venus above the western horizon as the sun sets? From the northern hemisphere, the ecliptic – the line in the sky that marks the path of the sun, as well as its attendant planets – makes a shallow angle with the horizon. The slant of the ecliptic is more perpendicular to the horizon in the southern hemisphere, making Venus stand tall during twilight. Shining at magnitude -4.4, Venus easily pierces ... Full Story
