July Moon at Ascending Node

   Saturday July 18th the very thin 27-day old waning crescent Moon will be crossing the plane of the ecliptic moving north. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit, and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.

   Does our Moon actually go around the Earth as many graphics show? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*

Comet in the Clouds

   This morning, July 13th, the sky was generally overcast with thin status type clouds in most directions, including the northeast where the comet was just starting to appear over the trees marking my local horizon. Fortunately the clouds were still transparent enough for the comet to be just barely visible to the naked-eye, but very visible with time exposure pictures.
   I was hoping to position my camera so that the Baseball player would look as if he were swinging at the comet but the clouds started to thicken in that direction as I moved off the road and into some tall grasses.
   The other planets that were very visible yesterday morning were hidden or blurred by the clouds. Jupiter shined through the clouds but not Saturn or Mars. The Moon light was reflecting off clouds brightening the sky in that direction. And Venus and Aldebaran were somewhat visible but it took a time exposure picture to catch the light from the rest of the stars making the v-shaped part of the Hyades.

Comet NEOWISE or NEOWOW!!

   Could it get much better than this? Five visible planets (Jupiter, Saturn, Mars, Venus, Earth); Moon-Mars conjunction; Venus-Aldebaran conjunction; 2 outer planets and a Dwarf Planet not naked-eye visible, and Comet 2020 F3 (NEOWISE). Icing on the ‘cake’ would have been to have the ISS orbit through the sky this morning.

Taurus Eyes Venus

   Saturday morning July 11th the inner planet Venus will be about 1o from the reddish star Aldebaran in Taurus the Bull. Aldebaran marks the ‘angry eye’ of the bull and is at one end of a v-shaped group of stars, the Hyades, that make up the face of Taurus.

   Venus has just spent the past several days traversing the Hyades, an open star cluster composed of hundreds of stars. The Hyades, at a estimated distance of 150 light years, is the closest open star cluster in our galaxy to the Earth.
    With binoculars the view of Venus, the Hyades, and Aldebaran is striking with Venus brightly shining at about a -4.5 apparent magnitude and Aldebaran with a 0.9 apparent magnitude.

   Also on this day the 20-day old waning gibbous Moon will be about 4-5o from the planet Mars.

Crescent Moon and the Hyades

   Saturday evening April 25th, at around sunset, the 3-day old waxing crescent Moon will be 1-2o from the reddish star Aldebaran in the constellation Taurus the Bull. Aldebaran is the brightest star in Taurus and also the brightest star of the v-shaped open star cluster the Hyades.

   The combination of the waxing crescent Moon with the stars of the Pleiades will make for a good view through binoculars.

The Moon and the Sisters

   Sunday evening March 1st the 7.5-day old nearly first quarter Moon, but still a waxing crescent Moon, will be 7-8o from the open star cluster the Pleiades. A few degrees from the Pleiades is another open star cluster the Hyades.
   These two open star clusters are part of the constellation Taurus the Bull. The Hyades make up the face of the Bull, while the Pleiades are located on the Bull’s shoulder. The Pleiades are also known as the “Seven Sisters”.

Taurus Head-Butts the Moon!

   Monday evening February 3rd the 10-day old waxing gibbous Moon will be about 3-4o from the reddish star Aldebaran in Taurus the Bull. Aldebaran, in mythology, represents the ‘angry eye’ of the Bull. Aldebaran is also the brightest star in the v-shaped Hyades open star cluster. Nearby is another open star cluster, the Pleiades, most observable as a small dipper-shape grouping of stars.

Waxing Gibbous Moon Near Aldebaran

   Tuesday evening January 7th the 13-day old waxing gibbous Moon will be about 3-4o from the reddish star Aldebaran. Aldebaran is known as the ‘angry’ red eye of the constellation pattern Taurus the Bull.

    Aldebaran is located at one end of a v-shaped cluster of stars making up the face of the Bull. This group of stars are all part of an open star cluster known as the Hyades. They are one of two naked-eye visible open star clusters within the boundaries of the constellation. The other one is the little dipper-shaped group known as the Pleiades.

The New Year’s Eve Skies of 2019

   The evening skies of this year’s New Year’s Eve begins at sunset with the 6-day old waxing crescent Moon to be about 3-4o from the outer planet Neptune. However with an apparent magnitude of 8 Neptune is only visible with optical assistance. On the other hand the crescent Moon with an apparent magnitude of -13 would be hard to miss!

   Later, at around midnight and centered over the southern horizon will be the ‘regular’ Northern Hemisphere winter display of stars. This is a familiar groups of bright stars in a rough circle around the constellation of Orion the Hunter, and sometimes referred to as the “Winter Hexagon” or ‘Winter Circle”.

   As the winter hexagon the member stars are Rigel in Orion the Hunter, Aldebaran in Taurus the Bull, Capella in Auriga the Charioteer, Pollux and Castor in the Gemini Twins, Procyon in Canis Minor, and Sirius in Canis Major.


   
   
   
   We’ve survived another orbit.
   
   
          Happy New Year!

Moon Conjunction with Aldebaran

   Tuesday evening, November 10th, about an hour or so after sunset, the 14.5-day old waxing gibbous Moon will be about 2-3o from the reddish star Aldebaran. Aldebaran is at one end of the v-shaped open star cluster the Hyades in Taurus the Bull.
