Astronomy
Welcome to the Boston Astronomy website ...

This website has been created by and is supported by a group of Boston, MA - area amateur astronomers. It is intended to be a convenient site to access news and information about astronomy and space-related activities of interest to the community and the public.


















       

            


      

Next Astronomy Course

 

Introduction to Astronomy

 

We sit around our campfires as the ancients did, and ponder. How did the Universe come into existence? How did life begin? Are we alone? But now we see a Universe around us containing black holes, dark matter, and expanding space. What does it all mean? In this course we’ll sit around our own campfire, and try to piece together the stories that modern astronomy is teaching us.  

 

One meeting will be at a local observatory.

 

No math or science background required!

 

Meets at the Cambridge Center for Adult Education, 8 Tuesdays: September 19 -  November 7, 2017, 7:45 PM - 9:15 PM.

A waxing crescent Moon provides a beautiful telescopic site as light from the Sun illuminates its cratered surface. Saturn is now higher up in the Southern sky at dusk. Its rings are always a stunning sight. Jupiter is setting now and will be lost from view by the end of the summer.

The Moon & Planets:

  

    

Planet Visibility:

    

In Evening (after sunset):

    Mercury, in W

    Jupiter, in SW

    Saturn, in S 

      

 At Midnight:

    Jupiter, in SW

    Saturn, in S

     

 In Morning (before sunrise):

    Neptune, in S

    Uranus, in SE

    Venus, in E 

         

     

Comets:

    

    •     There are no comets brighter than magnitude 8 visible this month.
  •          

Meteors:      

  •      The Southern Delta Aquariid meteors peak in the early hours of July 30th. The Moon won’t be around after midnight to detract from the view; rates could reach 25 meteors per hour, but best views are from the Southern Hemisphere

Pluto reaches opposition on July 10th; it rises at sunset, is highest at midnight, and sets at sunrise. At 3 billion miles distant,

 it is also as close to Earth as it gets this year and hence is at its brightest – a faint magnitude 14.2. It lurks among the dim stars above the Teapot of Sagittarius,

but its distance and tiny size put it out of reach of all but the largest backyard telescopes.

(July, 2017).

                          

           

     

                    

                      

Mid-summer presents excellent opportunities to see deep-sky objects –provided one travels far from city and suburban light pollution.

Bringing binoculars or a small telescope on a camping trip or to a star party will reveal some of the splendor of the Milky Way,

and the star clusters and nebulae near its heart.

   Just after sunset on the 28th, the waxing crescent Moon hovers over Jupiter,

with 1st-magnitude Spica nearby. Mercury has also been making an appearance low in the west.
