Earthsky Tonight — March 24, Moon close to Mars

Earthsky Tonight — March 24, Moon close to Mars

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org If you have been tracking the moon over the past few evenings, you know that it has been passing through some of the major players in the late winter, early spring skies. It skimmed the Pleiades star cluster on Saturday, then it plodded through Taurus the Bull, across Gemini the Twins and after midnight tonight it slips into Cancer the Crab. However, unlike Taurus and Gemini, Cancer is a very faint constellation, often not ... Full Story

Earthsky Tonight — Earthsky Tonight

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight, the waxing gibbous moon shines in front of the constellation Gemini, and is flanked by two beautiful stars. To the north of the moon is Capella, the beacon star in the constellation Auriga the Charioteer. To the moon’s south you will find Procyon, the brightest light in the constellation Canis Minor the Little Dog. When you look at the moon at the same time each day, the moon appears to be farther east of where it ... Full Story

Earthsky Tonight — Moon between Capella and Betelgeuse

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The rather wide waxing crescent moon will be shining in between two brilliant stars tonight. Capella, the brightest star in the constellation Auriga, will be beaming north of the moon, while Betelgeuse, the star marking the right shoulder in the constellation Orion, will be shining south of the moon. The moon swings full circle in front of the starry heavens in a little over 27 days. Twenty-seven days from now – on the night ... Full Story

Earthsky Tonight —Saturn closest, brightest, opposite the sun

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The planet Saturn is at opposition today. That means Saturn is opposite the sun in Earth’s sky. At opposition, Saturn rises in the east at sunset and sets in the west at sunrise. This is when Saturn comes closest to Earth for all of 2010. As a result, it is when Saturn shines most brilliantly in our sky. If you had a bird’s-eye view of the solar system today, you would see our planet Earth passing in between the sun and ...

Earthsky Tonight —The 2010 equinox comes on March 20

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The March equinox marks that special moment when the sun crosses celestial equator, going from south to north. It happens today at 17:32 Universal Time, or 11:32 a.m. Mountain Daylight Time. The March equinox signals the beginning of spring in the northern hemisphere and autumn in the southern hemisphere. The equinox is a hallmark in Earth’s orbit, but it is also an event that happens on the imaginary dome of Earth’s sky. ... Full Story

Earthsky Tonight — On eve of equinox, moon between Pleiades and Ram’s Head

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Just after sunset tonight you will spot the crescent moon above the western horizon. The moon floats between the faint head stars of the constellation Aries and the mythic sisters in the constellation Taurus, known as the Pleiades. The waxing crescent moon is only four days past new so it still appears to us as a rather thin crescent. This is a great time to tour the moon with your binoculars or telescopes. The craters and the ... Full Story

Earthsky Tonight — March 18: Venus in Pisces, moon in Aries

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight, as soon as it gets dark, the waxing crescent moon can help you locate the small constellation Aries the Ram. Look to the west, just above the place where the sun went down. You will see the thin crescent by the head of the constellation Aries. Although we draw in the constellation Pisces, this faint group of stars is not really visible at this time of year. Given clear skies, there is no way that you can miss the ... Full Story

Earthsky Tonight — Young moon and Venus low after sunset

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org It is nearly spring in the northern hemisphere. The March equinox - when the sun crosses the celestial equator from south to north – will fall on March 20. This time of year – near the spring equinox – is the most favorable for spotting a young moon. See if you can catch one today after sunset by the blazing planet Venus. A young moon is a thin waxing crescent moon visible in the west in evening twilight. The thinnest ... Full Story

Earthsky Tonight: March 15—The westward shift of Orion and all the stars

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org We got this question: “Orion seems to have moved and turned considerably in the last two weeks. Will Orion disappear before summer?” The answer is that all the stars and constellations shift westward as the seasons pass . . . and they also move westward in the course of a single night. Orion is no exception. Exactly when Orion will disappear from the evening sky – into the sunset – depends on your latitude. The farther ... Full Story

Earthsky Tonight—March 14, Leo loses his tail, we gain a constellation

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight’s chart again shows the evening sky high to the east. Below and to the left of the constellation Leo the Lion are dozens of very faint stars. They are Coma Berenices, otherwise known as Bernice’s Hair. The Greek-Egyptian astronomer Ptolemy and others considered it Leo the Lion’s bushy tail. Coma Berenices remained part of Leo until several hundred years ago, when it was first listed as a separate constellation. The ... Full Story
