1063    JANUARY 1, 2017:   Good Start to the New Year
The first week of the New Year begins with some interesting early evening visual and binocular observations. Check out Venus on January 1 as soon as it gets dark. The Goddess of Beauty will be found directly above and to the left of a thin, horned 14 percent waxing crescent moon. Look for earthshine with binoculars, the light reflected from the moon’s surface by a nearly full Earth. It will give the unlit portion of the moon a ghostly appearance. If the night is exceptionally clear, you’ll be able to see this ashen light with the unaided eye, and a reddish, fainter “star” above and just to the left of Venus. You will be witnessing the planet Mars. Train your binoculars upon Mars and look just below and to the right of the Red Planet, about the same angular distance that the horns of the moon appear separated through your binoculars. You should see a faint starlike object. That will be distant Neptune, mathematically and independently predicted (1845) by John Adams (English) and Urbain Leverrier (French), but officially discovered by the German astronomer Johann Galle in 1846. Galileo recorded Neptune in December of 1612 and again in January of 1613 while observing Jupiter, but he didn’t make the connection. If Sunday proves cloudy, another chance to view Neptune awaits on January 2 when the distance between Mars and Neptune will have grown twice as great, just over a degree. The 21 percent lit, waxing crescent moon will also be found in the same field of view. Likewise, but a little more difficult to view, will be Venus and the moon in the same field of view. Wide-angle binoculars will prove helpful here. By January 5, the first quarter moon will be stationed five degrees under the planet Uranus. As the moon keeps jogging east over the next three days, watch as it approaches Aldebaran, the yellow-orangey alpha star of Taurus the Bull. The moon is to the right of Aldebaran on the 8th and to Aldebaran’s left by January 9.

[Mars passes Neptune]
Mars was separated from Neptune on the night of January 1, 2017 by just over one-half degree. Compare the map below with the picture above to see that stars of +13 magnitude were recorded in just 20 seconds. A Tele-Vue 101mm, F/7 refractor was mated to a Canon 80DSLR at ASA 400.

1064    JANUARY 8, 2017:   So You Want to Go to Space…?
What is it like to go into outer space? I’ve read a lot of insightful descriptions: the years and years of training, so that your tasks are so tightly choreographed that it almost becomes as natural as breathing, the intimidation of the machinery that will take you into space, and the fact that any mistake can be fatal. Space is unforgiving and to be unprepared is to face certain death. Mike Massimino in Spaceman, Crown Archetype, New York, 2016, probably has provided the most personal portrayal of his first day in space. He was a Mission Specialist/Spacewalker on STS-109, launched on March 1, 2002, the fourth mission to the Hubble Space Telescope. “Mass,” as he was nicknamed by his fellow astronauts, wanted to go to space his entire life. Mass wrote, “And you feel horrible, absolutely terrible. Adjusting your body to space is painful.” Bodily fluids shift. “In space [fluids are] are free to float up to your head. Everybody’s face was red and flushed and puffy.” Astronauts feel as if they have unending sinus blockage. Food also loses its taste. “…Your spine elongates—again, because there’s no gravity keeping it compressed. You grow about an inch in space, and all those sensitive muscles in your back have to stretch and adjust. That’s painful too.” But the worst is probably the nausea induced by the fact that “your eyes… are telling your brain that you’re moving, and your inner ear [is] telling your brain that you’re still, because your inner ear [fluids don’t] move when you’re weightless.” Since there is no up or down in space, performing a summersault feels like you are remaining perfectly motionless while the interior of the ship is whirling around you “which causes the worst vomit-inducing feeling of vertigo you’ve ever experienced.” Normally after a few days, the nausea subsides, but about a third of all Shuttle astronauts suffered from queasiness throughout their entire mission. Having participated in scores of small aircraft parabolas, where weightlessness is induced for about five seconds, I know that I’d be in the perpetually “not so pretty group” if I went to space. I’m glad to be living on terra firma.
 

1065    JANUARY 15, 2017:   Rock on, Orion!
The winter constellations are all ablaze during the next two months, and foremost on the list of any frosty evening is the Winter Group with its premier pattern, Orion the Hunter, nearly due south at 9 p.m. Most recognizable are his three bright belt stars in a close, straight, upward tilt: Mintaka (upper right), Alnilam (center), and Alnitak. In South America, they are called the Three Marys, but in reality, they are part of an association of very hot, young, super luminous stars that were born at the same time and live in the same stellar neighborhood. Above and to the belt’s left is Betelgeuse, a red supergiant, the brightest star of its type in the sky, just about ready to go supernova. Its rival is Antares of Scorpius, a summer constellation. When Betelgeuse detonates, between now and perhaps a million years into the future, its brilliance will rival that of a gibbous moon, but seen as a pinpoint of light in the sky. To Betelgeuse’s right is Bellatrix, another young, hot blue star, only 250 light years from the sun and recently born into the rich mix of gas and dust that populates the Orion region of space. Below Bellatrix is Rigel, the brightest blue supergiant star in the heavens. Rigel, at 860 light years distant, shines with a luminosity of 85,000 suns, and is the size of Mercury’s orbit. Like most of the stars that compose the outline of the hunter, Rigel will probably go supernova in the next several million years. Left of Rigel is Saiph, another stellar powerhouse 720 light years distant, and radiating some 65,000 times the energy of the sun. While being dazzled by the bright stars of Orion’s torso, do not forget to view his sword hanging below the belt stars. All three components are clusters of stars by themselves, but the most famous, the fuzzy “star” at the sword’s center is the Orion Nebula. It represents the location of the youngest active region of stellar birth in the galaxy. Binoculars will easily show its nebular characteristics. Rock on, Orion!
