Earthsky Tonight — May 4, Moon drowns Eta Aquarid meteors before dawn

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The Eta Aquarid meteor shower is now taking stage in the dark hours before dawn. It has expected to peak in the predawn sky on Thursday morning – May 6, 2010 – from roughly two hours to one hour before sunrise. Look on our almanac page for your sunrise time. Under ideal conditions, this shower can produce up to 20 to 40 meteors per hour. However, in 2010, the last quarter moon will wash out all but the brighter meteors ... Full Story

Earthsky Tonight —May 3, Can you see Aldebaran near Venus?

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org You should have no trouble spotting Venus after sunset, even though this dazzling world appears quite low in the west at dusk and early evening. Don't tarry when looking for Venus, for this blazing beauty follows the sun beneath the horizon roughly two hours after sunset. Venus and Aldebaran, the brightest star in the constellation Taurus, are in conjunction today. Generally, two heavenly bodies do not appear in the same ... Full Story

Earthsky Tonight — May 2, Drive a spike to the star Spica in May

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Yesterday we talked about learning to ‘follow the arc’ to the star Arcturus in the constellation Bootes. You just follow the curve in the Big Dipper’s handle until you see this orange star. Tonight, let the Big Dipper introduce you to another bright star. This star is Spica in the constellation Virgo the Maiden. You can ‘follow the arc’ to Arcturus AND ‘drive a spike’ or ’speed on’ to ... Full Story

Earthsky Tonight — May 1, Follow the arc to the star Arcturus in May

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org It is now the perfect time to look outside in the evening and learn a phrase useful to sky watchers. The phrase is: ‘follow the arc to Arcturus.’ First, locate the Big Dipper asterism in the northeastern sky. Then draw an imaginary line following the curve in the Dipper’s handle until you come to a bright orange star. This star is Arcturus in the constellation Bootes, known in sky lore as the ‘bear ...

Earthsky Tonight — April 30, Star hopping from constellation Orion

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Rebecca wrote, “What is ’star hopping?’ What does that mean?” Rebecca, amateur astronomers use star hopping to go from stars and constellations they know … to ones they don’t know yet. First, look for noticeable patterns on the sky’s dome. One very easy pattern to find at this time of year is the constellation Orion the Hunter. You will find it descending in the west after sunset. Orion is easy to find ... Full Story

Earthsky Tonight—April 29, Moon and Scorpion rise as Orion sets

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Like clockwork, the constellations rise and set 4 minutes earlier with each passing day. Four minutes doesn’t sound like much, but it adds up after a while. For instance, the stars rise and set one-half hour earlier with each passing week, or 2 hours earlier with each passing month. That is 6 hours difference after one 3-month season. In late April, the red supergiant star Antares rises in the southeast around 11:00 ... Full Story

Earthsky Tonight — April 28, Orion descends in the west each evening

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org At this time of year, the famous constellation Orion is descending in the southwest to west in the hours after sunset. Orion is noticeable for its bright stars and its distinctive pattern on the sky’s dome. Look for three stars in a short, straight row. Then look for Betelgeuse and Rigel, Orion’s brightest stars. If you didn’t come to know it this winter, check it out now. It is one of the most distinctive of all ... Full Story

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Astronomically speaking, the moon turns full tomorrow – on Wednesday, April 28 – at precisely 12:18 Universal Time (7:18 a.m. Central Time). An astronomical full moon occurs at that fleeting instant when the moon stands most directly opposite the sun in Earth’s sky. For general reference, however, we can say that the full moon shines from dusk until dawn tonight. This April full moon is the second full moon of the ... Full Story

Earthsky Tonight — April 26, Moon, Spica and Saturn in Virgo

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight, the almost-full waxing gibbous moon sits close to Spica, the brightest star in the constellation Virgo the Maiden. The star-like point of light above the moon this Monday evening is actually no star at all but Saturn, the 6th planet outward from the sun. Although the moon pairs up with Spica for only a day or two each month, you can always use the Big Dipper to star-hop to Spica after the moon goes down the ... Full Story

Earthsky Tonight — April 25, Bright object near moon is Saturn

In the northern hemisphere, people have called the April full moon by many names but with a common theme – Planter’s Moon, Seed Moon, Flower Moon, Growing Moon, Awakening Moon. Between now and April 28, you’ll see the ... Full Story
