Triangulating with the Moon

   Tuesday morning, August 15th the 23-day old first quarter Moon will be the point of a celestial triangle with the two open star clusters, the Pleiades, and the Hyades as this graphic shows. The v-shaped Hyades forms the face of Taurus the Bull while the ‘dipper-shaped’ Pleiades lies along the Bull’s shoulder. Both open star clusters are about 8o from the Moon.

Venus Gets Buzzed!

   Tuesday morning August 1st the inner planet Venus will pass within 3o from the open star cluster, M-35. Also known as the ‘Beehive Cluster’ this is an open star cluster located near the feet of the Gemini Twins. M-35 consists of several hundred stars and is approximately 2800 light years from our solar system. The star cluster has an apparent magnitude of around 5.5 making it naked-eye visible and certainly a binocular-worthy object.

   Through binoculars it is easy to see M-35 as well as a 3rd and a 2nd magnitude star within a couple of degrees. However the ‘ruler’ of the binocular field of view is Venus with a -4.0 magnitude.

Moon is in Conjunction With Uranus and Eris

   Monday morning July 17th the 23-day old waning crescent Moon will be within a few degrees from the outer planet Uranus and dwarf planet Eris.
   Another dwarf planet, Ceres, the closest dwarf planet to the Earth is above the north-eastern horizon before sunrise local time. Ceres, formerly known as an asteroid, and the largest of the main belt asteroids, had enough mass to form into a spherical shape, one of the requirements for planet classification. Thus allowing it to be included in the group of known dwarf planets – most of which reside in orbits beyond the outer planet Neptune.
   Also very visible over the eastern horizon is the inner planet Venus shining very brightly near the reddish star Aldebaran in Taurus the Bull.

Waxing Crescent Moon Near the Beehive Open Star Cluster


   Monday evening May 29th the 5-day old waxing crescent Moon will be within 3-4o from the open star cluster M-44, or as it probably more known as the “Beehive Cluster”, or from Latin, Praesepe, meaning “manger”.
   Both of which fit easily within the field of view of binoculars.

   This open star cluster, as a group, has a 3rd-4th apparent magnitude and to the naked eye appears as a fuzzy patch of light in Cancer the Crab. M-44 is near the 4th magnitude star Asellus Australis, the star that marks the splitting point for the Y-shaped star pattern.

Don’t Panic, It’s Only A Towel!


   Thursday May 25th, or any day that is May 25th we celebrate, in our own way, (yes we do) the Book,
Hitchhiker’s Guide to the Galaxy
, by Douglas Adams. What is the significance of the towel? Click on the graphic to enlarge it to a readable size to find out.
   So be a hoopy frood and click on this link to visit the Towel Day web site.

   Overheard on Jeopardy: “42.”
And the answer is: “What is the meaning of life?”

An Astro 2fer

   The title may be somewhat of a U.S.A. expression but it simply means there are two Astronomy events I am writing about and have combined them into one posting. So around sunset local time on Wednesday May 3rd the waxing, or very nearly first quarter Moon, will be within a few degrees from the star Regulus in Leo the Lion. While over the western horizon the ‘Red Planet’ Mars is near the stars making up the face of Taurus the Bull – the Hyades open star cluster.

Moon Cruises Past Planets and Stars

feb5-bino
   Over the next several evenings the Moon, as it orbits toward the east and waxes from crescent to first quarter phase will pass by several planets, dwarf planets, and star clusters. On the evening of February 5th the Moon will be close to the reddish star Aldebaran, the ‘eye’ in the face of the angry bull, Taurus. This should make for a nice view with binoculars or low power eyepiece when the Moon will sort of overlay the stars of the open star cluster the Hyades.

   These two animated graphics show the sky as viewed from Quito Ecuador at 0o latitude, and my home latitude of approximately 40o North. They show the sky at one day intervals starting with February 1st and ending with February 5th.
