Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Two major astronomical events are taking place today. First, our planet Earth is at perihelion – its closest point to the sun for the year. Second, tonight’s waning gibbous moon pairs up with a brilliant planet – the world next door – Mars.

Earthsky Tonight – Moon near Gemini’s stars

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Here is the moon again, in line with the the constellation Gemini’s brightest stars, Castor and Pollux, and not that far from the planet Mars. The moon will be even closer to Mars tomorrow night. Many people write to ask about the fact that, from Earth, we see only one side of the moon. The moon rotates about once a month, in contrast to the once-a-day rotation of our own planet ... Full Story

Earthsky Tonight – Dec 29 2009, Moon and Pioneer 10 spacecraft align in Taurus

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight, the waxing gibbous moon shines in front of the constellation Taurus the Bull. Unfortunately, the big, bright moon will wash out most of the constellation’s stars. Despite the moonlit glare, you may note Taurus’ brightest star, Aldebaran, to the right of the moon this evening, and Elnath, Taurus’ second brightest star, to the left of the moon. For the second time this month, the moon and the ... Full Story

Earthsky Tonight – Dec 28 2009 Moon glides by Pleiades on December 28

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight, moving eastward as it always does in orbit around Earth, the moon will pass by the Pleiades. Our sky chart shows you what the moon and the Pleiades cluster might look like through binoculars this early evening. Early stargazers sometimes described the Pleiades as a ‘swarm of bees’ in the night sky. Modern stargazers sometimes mistake it for the asterism known as the Little Dipper. The true Little ...

Earthsky Tonight – Dec 27 2009, Bellatrix

Earthsky Tonight – Dec 27 2009, Bellatrix – Orion’s third brightest – means ‘Female Warrior’

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The constellation Orion takes center stage this month and rightly so. With an inordinate number of bright stars, it is one of the most prominent constellations in the sky. Look for Orion in the east-southeastern sky from around 6 to 7 p.m. A while ago, we talked about Orion’s two brightest stars, but the third-brightest star in Orion, Bellatrix, is often overlooked. According to Richard Hinckley Allen’s ... Full Story

Earthsky Tonight – Dec 26 2009, Moon near Ram’s head on December 26

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org As seen from North America, the waxing gibbous moon will shine right below the head of the constellation Aries the Ram this evening. So it’ll be easy to locate the Ram’s head, but the moonlit glare will make it difficult to see the 3 stars that depict the head: Hamal, Sheratan and Mesarthim. Mesarthim will be especially hard to see. This evening, the Pleiades star cluster shines nearly 30 degrees to ... Full Story

Earthsky Tonight – Dec 25 2009 Northern Cross

Earthsky Tonight – Dec 25 2009 Northern Cross stands upright on winter evenings

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org We get many questions from people in northern latitudes about if and when they can view the Southern Cross in their portion of the sky. The truth is that unless you live close to the tropics (Hawaii, or the southernmost parts of Texas or Florida for those of us in the U.S.), you will not be able to view the Southern Cross, also known as the constellation Crux. To find out how to locate Crux in Hawaii right now, look ... Full Story

EathSky Dec. 24, 2009 – Southern Cross visible in Hawaii before sunrise

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Here’s a gift. A reader asked us, When can I see the Southern Cross in Hawaii? At this time of year, Hawaiians can see the Southern Cross, which is also known as the constellation Crux, in the wee hours before dawn. The Southern Cross stands pretty much upright, but quite low in the southern sky. Notice the two nearby stars, Rigel Kentaurus and Hadar. Rigel Kentaurus is more commonly known as the alpha star in the constellation ... Full Story

Earthsky Tonight – Dec 23 2009 Star-hop to Mercury from the Summer Triangle

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The first three stars to pop out into your western sky after sunset are Vega, Altair and Deneb. These brilliant stars make up the huge asterism known as the Summer Triangle. An asterism is a star formation that is not an officially recognized constellation. Don’t mistake the planet Jupiter (outside of our sky chart) for a Summer Triangle star. Jupiter beams in the southwestern sky, to the left of the Summer ... Full Story
