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

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

Earthsky Tonight — April 24, Waxing gibbous moon pairs with Saturn

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight, the oval-shaped waxing gibbous moon shines close the ringed planet Saturn. At this time yesterday, a somewhat thinner waxing gibbous moon shone close to Regulus, the brightest star in the constellation Leo the Lion. Why has the moon moved? The fact is that – every day – the moon travels about 13 degrees eastward in front of the backdrop stars. (The moon’s diameter equals about 1/2 degree, and your fist ... Full Story

To the east of the moon shines the golden planet Saturn. If you cannot distinguish color with the unaided eye, try binoculars. By tomorrow night, a somewhat fuller waxing gibbous moon will have moved away from Regulus and closer to Saturn. Regulus is the brightest star in the constellation Leo the Lion, and it ...

Earthsky Tonight — April 22, Lyrid meteors may still

Earthsky Tonight — April 22, Lyrid meteors may still be flying before dawn

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Here is the constellation Lyra again – a closer look than on Tuesday. This constellation rises over your north-northeastern horizon around 10 to 11 p.m. tonight and marks the radiant point of the Lyrid meteor shower. The Lyrids were predicted to put forth the most meteors before dawn this morning. However, meteor showers are hard to pin down, so you may see as many or more meteors in the wee hours before dawn tomorrow. You ... Full Story

Earthsky Tonight — April 21, Moon and Mars tonight, Lyrid meteors before dawn

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org As soon as darkness falls tonight, look for the planet Mars quite close to the moon, which reached its first quarter phase today at 1:20 p.m. Central Time. The moon and Mars remain close together throughout the night, and descend westward throughout the evening hours. These two worlds set beneath the western horizon in the wee hours after midnight. The annual Lyrid meteor shower streaks the nighttime tonight from late ... Full Story

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The 2010 Lyrid meteor shower is now picking up steam. This shower is expected to produce the most meteors in the dark hours before dawn on Thursday, April 22. The evening before, on April 21, Mars will be near the moon. The approximate direction of the radiant point for the Lyrid meteors is toward Vega, the heaven’s 5th brightest star and the brightest light in the constellation Lyra. The radiant point for the meteors ... Full Story

Earthsky Tonight — April 19, two stars lead to constellation Hercules

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The constellation Hercules the Kneeling Giant can be seen ascending in the east-northeast on these spring evenings. Our chart today shows the sky for late night, when all of these objects are well up in the northeastern to eastern sky. The stars Arcturus and Vega can help you identify Hercules, whose most noticeable pattern is a squarish figure in the center of the constellation. This sky pattern, or “asterism,” is ... Full Story

Earthsky Tonight — April 18, Spica, your guide star

Earthsky Tonight — April 18, Spica, your guide star to Omega Centauri

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Silvery-blue Spica, the only prominent star in the constellation Virgo, acts as your guide to the Omega Centauri globular star cluster. To the unaided eye, Omega Centauri looks like a fairly faint (and possibly fuzzy) star. Very few of the Milky Way galaxy’s 250 or so globular clusters are readily visible without optics. To find Spica, extend the curve of the Big Dipper handle, as illustrated on our April 4 EarthSky ... Full Story

Earthsky Tonight — April 17, Heavenly Chariot flies

Earthsky Tonight — April 17,  Heavenly Chariot flies in west at nightfall

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org As darkness falls, there are several ways to distinguish the brilliant star Capella from the other bright stars in the western half of sky. Capella, the northernmost first-magnitude star, is the farthest bright star to your right as you’re facing west. In addition, Capella looks yellow, like our sun. Moreover, Capella has a famous trio of starlets accompanying her, dubbed “The Kids.” Moreover, at nightfall and early ... Full Story
