OBJECTS IN THE SKY FOR JANUARY
Solar System Objects
The only planet you can see in the evening sky without a telescope now is Venus, and that will be true until well into Spring. But, wow! What a show Venus is putting on in the southwest after sunset. The planet is almost at its greatest possible eastern elongation (that’s astronomer-talk for: as far into the evening sky away from the sun that it’s possible for Venus to appear). And, at magnitude -4.0, it is the brightest object other than the moon in our evening sky this month. Because it’s low in the sky and we’re looking at it through a lot of Earth’s jittery atmosphere, Venus can appear to change colors. If you’re not familiar with it, and you’re driving along looking at Venus, it can also appear to quickly change positions. So, we’re expecting the usual calls from people convinced that Venus is a UFO! Through the Hyde telescopes, Venus will resemble a tiny, bright gibbous moon.
Lunar phases this month: On Saturday, January 11, the moon is just past Full and rises before the observatory opens at 7:00 p.m., remaining in the sky all evening (and blotting out faint stars). During Full moon, the sun is shining directly down on the lunar surface, producing no shadows, so surface features are hard to make out; on Saturday, January 18, the moon is approaching Last Quarter and rises after the observatory closes.; on the 25th, the moon is just past New phase (the Dark of the Moon), and will appear as a very thin crescent low in the west just after the sun sets, but it will drop below the horizon at 6:26 p.m., before the observatory opens at 7:00.
Deep Sky Objects
Deep Sky Objects are those beyond the solar system: galaxies, nebulae and stars. Our visual guides to these objects are the constellations. In the northern sky during Winter, the ubiquitous circumpolar constellation, the Big Dipper (Ursa Major), has revolved around the pole star and no longer looks so dipper-ish: more like a giant question mark … a sure sign of the coldest season. The bright stars and constellations of winter now appear against the blackness of intergalactic space. We are looking in the opposite direction of our galaxy’s center, out into our spiral arm at Orion and Canis Major, the Big Dog, The most obvious marker of this constellation is Sirius, the brightest star in the sky — other than our sun. Its presence high in the south is the surest sign of astronomical winter. Other than the fact that we are freezing our tootsies standing outside to see it!
