A Divine Winter Astronomical Jewelbox

Not only has Venus and Jupiter become important and beautiful figures in the winter sky (for us in Northern Hemisphere latitudes!), but the moon has added to the excitement in viewing these jewels, in their jewel box: the night sky. Although the moon presently is obscuring many stars and dimmer planets, Jupiter and Venus shine on strong, with Mars, Mercury, and Saturn pulling along nicely as well. You too can view these planets, and not only with just a telescope or binoculars, Jupiter and Venus are visible just with the naked eye.

If you look to the southwest over the next few nights (late January to early February), Venus and Jupiter rise after sunset, and are in full stature by the sun has pulled itself under the horizon. On January 31, the moon and the Pleiades cluster will gracefully (and by all means aesthetically!) crown Jupiter, and Venus to the south of it. This might create a beautiful winter astronomical scene, minding the weather and potential cloud cover. The moon is currently the brightest object in the sky, the second, Venus, and the third, Jupiter tonight, as it will remain until the moon becomes new again.


Below are personal photos of the Jupiter-Moon conjunction on January 30, 2012. The time was approximately 6:00 pm EST, and as you can see, the moon was high and brightly shining! Jupiter was south of the moon, and left, in the picture below. The following picture is that of Venus, with clouds and trees in the background.



Although this might seem like nothing now, "consider this a preview of even better things to come," Spaceweather.com encourages! The two planets are going to become closer to one another, with the moon "swinging" in late February. That is when another conjunction of the planets will take place (remember the Four-Planet Dance of 2011?). March 12 the major conjunction when Venus and Jupiter converge within a 3 degree angle. "The winter planet show is just getting started, so stay tuned!"

February 3, 2012 places the moon in "the Winter Circle," as EarthSky.com illustrates below. By this point, the moon will be almost full, and bulging with scintillation! The moon is situated in Orion, as you can see Rigel and Betelgeuse being part of the star group. Capella crowns the circle, with Castor and Pollux to its left. Aldebaran is on its right.

As we fully divulge into winter, remember the planets and how beautiful they are: they are jewels in this wonderful jewel-box!

Events for the Week 6/4 to 6/11

The partial solar eclipse was a great treat for those who lived in the north. June 15: Total Lunar eclipse for those who wish to experience one! (Only Asia, Europe, and Africa though!)

Events for 6/4

Pollux and Castor sits at the upper right of the moon tonight. Look for Procyon again, though disappearing under the horizon soon. (See below image).



Events for 6/5

Castor and Pollux start to fade as the moon waxes to first quarter. The moon, beside from visiting Gemini, will come and see Cancer (the faintest constellation in the Zodiac) and Messier 44, the 'Beehive' Star Cluster. The moon will sit in Cancer and Messier 44 will be about right above the moon and a little to the right. [The Beehive Cluster is actually one of the closer start clusters to our solar system. It has been viewed since Galileo and Ptolemy; even without a telescope it will look like a 'nebulous' object. [But] If you have a nice telescope, you'll see this.] (Image: Messier 44 from Wikipedia)


Events for 6/6

The big Dipper (probably the most well-known constellation) is extremely high this June month. In order to find it's lesser 'twin,' the small Dipper, locate two other stars outside its bowl (The Pointers), and they'll show you the path to the north star: Polaris. Once you've found Polaris, you can find the little Dipper. "Polaris marks the end of the handle of the Little Dipper. You need a dark night to see the Little Dipper in full, because it’s so much fainter than its larger and brighter counterpart." EarthSky writes.

Scorpius also begins to rise these evenings in the extreme southeast.  Antares, its brightest star, will be visible farther to the constellation's upper-right.  Sparkly, summery Scorpius is rearing up in the south-southeast these evenings.


Events for 6/7

Titan, A satellite fo Saturn, can be viewed excellent tonight. Saturn's Moons tracker will help you identify its fainter 'friends.' Meanwhile, the Moon's out partying again now with Leo. Regulus (Leo's brightest star) will be shining bright about northwest of our moon. EarthSky graciously writes about occultations of the Moon and Regulus: 
The moon’s orbit sometimes brings it close enough to Regulus to occult or eclipse it, although this hasn’t happened since May 12, 2008 and will not occur again until December 18, 2016. There is no occultation tonight, but the moon swings fairly close to Regulus for a day or two every month. Of course you know that they are not really close. A trip to the moon covers a distance equivalent of approximately 10 times around the earth, or nearly 250,000 miles. If you could drive that distance nonstop at 50 miles per hour, it would take more than 6 and 1/2 months. But Regulus is a large, hot star, surpassing our sun in size and energy. At more than 77 light years’ distance, it is nearly 2 billion times farther away than the moon. A trip to Regulus at 50 mph would take about one billion years!

Events for 6/8

First-quarter Moon shines south of Leo at exactly 10:11 pm EDT. Other than that, no much happens tonight.

Events for 6/9

In the next few days, the moon will pass under Saturn and Porrima (6/9), the pass under Arcturus, high above our celestial satellite, (6/10) and finally down and to the right of the moon, around 10 or 11pm, the little dipper floats by.

Notes: Saturn and Porrima are one-fourth degree around the 9th!


"With summer almost here, the big Summer Triangle is coming to dominate the eastern sky. Its topmost and brightest star is Vega, plain to see. Look lower left of Vega, by two or three fist-widths at arm's length, for Deneb, the brightest star in its area. Farther to the lower right of Vega is Altair." SkyandTelescope writes.
