EarthSky Tonight—Oct. 31, Arcturus is a Halloween ghost of the summer sun

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Every Halloween – and a few days before and after – the brilliant star Arcturus sets at the same time and on the same spot on the horizon as the summer sun. What’s more, this star rises at the same time and at the same place on the horizon as the sun does during the dog days of summer. So – around Halloween – it is as if Arcturus is a fainter ghost of the summer sun. At mid-northern latitudes, Arcturus now sets about 2 ... Full Story

The cycle lasts exactly 2 days, 20 hours and 49 minutes. All the while, the star remains visible to the eye. Algol’s brightness variations are not due ... Full Story

EarthSky Tonight—October 21, Full Hunter’s Moon of 2010 tomorrow

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight’s moon is only a prelude to the full Hunter’s Moon that will grace North American skies tomorrow – on Friday evening, October 22. Nevertheless, the moon looks plenty full tonight, too, as it parades across the sky from dusk until dawn. The moon will reach the crest of its full phase tomorrow at precisely 8:46 p.m. Central Time (9:46 p.m. Eastern Time, 7:46 p.m. Mountain Time, 6:46 p.m. Pacific Time). Elsewhere in the ...

EarthSky Tonight-June 24: Earth passes between sun and Pluto tomorrow

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Pluto – the former planet – comes to opposition on June 25, at 19:00 Universal Time. That is when we on Earth pass more or less between the sun and Pluto, so that this distant world is now opposite the sun in our sky. Of course, in Pluto’s case, it is not exactly opposite since the orbit of Pluto is inclined to the plane of the solar system by 17 degrees. That is a greater inclination than the orbits of Mercury, Venus, ... Full Story

EarthSky Tonight-June 23: Waxing gibbous moon passes near Scorpion’s Heart

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight the moon returns to the constellation Scorpius the Scorpion. The brightest star in the immediate vicinity is Antares, whose name means “like Mars,” because of its similar reddish hue. If you remember your Greek mythology, or perhaps episodes of Xena: Warrior Princess, Ares is the god of war, the counterpart to the Roman god Mars. You can perform the color comparison yourself, because the planet Mars lies in the ... Full Story

These three stars are sometimes called the Crown of the Scorpion. Scorpius – which now rises in the south-southeastern sky at early evening, is the constellation of the Scorpion. Individually, the Crown stars are Graffias, Dschubba, and Pi Scorpii. It is rare when star patterns on our sky’s dome have anything to do with real associations of stars in ... Full Story

Earthsky Tonight—June 1: Big Dipper high in north on June evenings

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Here is the legendary Big Dipper, now high in the north during the evening hours. It is one of the most familiar star patterns in the sky because its shape really resembles a dipper. Less familiar – and tougher to find – is the Little Dipper. Here is how you can find it. First, locate the Big Dipper in the northern sky during the evening hours. Notice that the Big Dipper has two parts: a bowl and a handle. See the two outer ... Full Story

Earthsky Tonight — April 8,  Mercury at greatest evening elongation

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Mercury – the solar system’s innermost planet – goes unnoticed by most people, because it’s so often obscured by the sun’s glare. Even when Mercury is visible – like it is now – it takes a deliberate effort to catch this rather elusive world. This evening, Mercury reaches its greatest angular distance east of the sun. What this means is that Mercury sets a maximum time after sunset today, enabling you to spot ... Full Story

It will be the starlike object close to tonight’s almost-full waxing gibbous moon. Note Saturn’s golden color, if you can. If you cannot, try viewing this world through binoculars. Better yet, look at Saturn’s golden color and glorious rings through a telescope. By about midnight, Saturn will be high in the southern heavens. Why Saturn ... Full Story
