Earthsky Tonight, January 31, 2010: Watch for Leo the Lion, harbinger of spring

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The moon, planets and stars – like the sun – rise in the east and set in the west. Tonight, the waning gibbous moon will rise an hour or so after nightfall. However, the constellation Leo the Lion won’t be totally above the horizon until about 2 hours after darkness falls. Like the sun, the stars swing full circle across the sky once a day. Unlike the sun, however, the stars return to the same place in the sky in ... Full Story

Earthsky Tonight – January 28, 2010: Does Mars ever appear as large as the full moon?

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight, the planet Mars will be at at its biggest and brightest until the year 2014. Does that mean that Mars will be as large as the moon tonight? Check it out for yourself. This evening, look to the lower left of tonight’s almost-full waxing gibbous moon for a ruddy-colored “star.” That “star” is actually Mars, the 4th planet outward from the sun, shining most brightly in Earth’s sky for ...

Earthsky Tonight – January 27, 2010 Mars comes closest to Earth

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Today, the planet Mars comes closest to Earth for all of this year. Mars is at its best about every two Earth years, and now is the time. In fact, this planet is now shining at its brilliant best for several years to come. Tonight’s close encounter between the Earth and Mars will be the closest until the year 2014. Because it’s close, Mars is also particularly bright in Earth’s sky right now. ... Full Story

Earthsky Tonight – January 26, 2010

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org As seen from Earth, the planet Mercury – the solar system’s innermost planet – appears to be closely tethered to the sun. But tomorrow morning, Mercury will swing to the end of its tether – the outermost point of its orbit. Astronomers call this event Mercury’s greatest western elongation. Therefore, Mercury will appear in the early dawn sky before sunrise for the next week or so. However, it’ll still ... Full Story

Earthsky Tonight – January 25, 2010: Moon close to Aldebaran, Pleiades

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org We are displaying a larger swath of sky than we usually do on tonight’s chart. That’s because we’re showing you how to star-hop from the three stars of Orion’s Belt to the star Aldebaran and the Pleiades star cluster. Aldebaran and the Pleiades cluster reside within the constellation Taurus the Bull. However, you won’t need Orion’s Belt to locate Taurus the Bull tonight, because the bright waxing ... Full Story

Earthsky Tonight- January 24: Moon and Pleiades in south at nightfall

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The waxing gibbous moon and the Pleiades star cluster are found high in the southern sky at nightfall and early evening. Although the moonlit glare may make it difficult to see this tiny, dipper-shape cluster of starlets tonight, be sure to check out the Pleiades on a dark, moonless night. Starting the first weekend of February, the moon will leave the evening sky for at least a week, staging the Pleiades in ... Full Story
