Planetary Conjunctions

Looking to the East horizon, July 17-19, the Moon, Venus and Mars will be in conjunction. On the 17, the moon will be above the other two, then next to Mars on the 18th, and to the left of Venus on the 19th.

Look just above the western horizon on the night of July the 24th and you may be able to see Saturn sitting above the Moon, as they dip below the horizon.

Meteor Showers (See American Meteor Society for more info.)

"After several months of low activity the meteor rates for both hemispheres see a marked increase in July. In the northern hemisphere the change is not noticeable until mid-month when several southern radiants, the Perseids, and sporadic rates all increase in activity." - Robert Lunsford, AMS Meteor Activity Outlook (week-by-week)

Delta Aquarids (July 21 - August 31) - maximum activity (15-20 meteors/hr) about July 29; Appears to radiate from the constellation Aquarius, thus, it's name; best viewed during the pre-dawn; Wikipedia - Southern Delta Aquariids

Perseids (July 13 - August 26) - maximum activity (50-80 meteors/hr) about August 12/13; One of the best meteor showers of the years; Created from the debris of Comet Swift-Tuttle, the largest of the known objects to pass Earth; Appears to radiate from the constellation Perseus, thus, it's name.

When I Heard the Learn’d Astronomer

 by Walt Whitman, Leaves of Grass (1897 edition)

When I heard the learn'd astronomer,

When the proofs, the figures, were ranged in columns before me,

When I was shown the charts and the diagrams, to add, divide, and

     measure them,

When I, sitting, heard the astronomer, where he lectured with much

     applause in the lecture-room,

How soon, unaccountable, I became tired and sick,

Till rising and gliding out, I wander’d off by myself,

In the mystical moist night-air, and from time to time,

Look’d up in perfect silence at the stars.
