Mysteries of the Universe: Black Holes, Dark Energy, and More: Fall Semester

        

Fifty years ago, humans landed on the Moon. We’ve since discovered countless planets orbiting other suns, and potentially habitable environments in our own solar system. We know how big the universe is, how old it is, and what’s it’s made of. But we also face mysteries: black holes, dark matter, and dark energy. We’ll cover everything you’ve always wanted to know but were afraid to ask. No math or science background required. You’ll also get to use a large telescope at a local observatory.

                        

Meets at the Cambridge Center for Adult Education, 8 Tuesdays: Sept. 17 - April 2 - Nov. 5, 2019 - 7:45 PM - 9:15 PM.

We Hack the Moon

Draper

555 Technology Square

Cambridge, MA

http://www.wehackthemoon.com/events

An exhibit at Draper features an enormous spherical sculpture of the moon. On Saturday, the sculpture will illuminate at the very moment that Neil Armstrong first set foot on the moon. The exhibit also includes a simulator of the lunar landing experience and delves into the engineering breakthroughs that propelled astronauts onto the lunar surface.

Stellafane

Springfield, VT

Keynote Speaker: Dr. Alan  Stern - New Horizons Update

Join us Saturday evening for an interesting talk about the New Horions mission and the flyby of Ultima Thule. In 2015 Alan Stern, principle investigator of the New Horizons mission, gave one of the most dynamic and captivating keynote talks we have had at Stellafane, descibing the New Horizons Pluto flyby barely a month after the event. We are very pleased to have him back at Stellafane! Dr. Stern will give us a mission update on New Horizons, and tell what we observed and learned about Ultima Thule, a Kuiper Belt Object and the farthest solar system object ever visited by a spacecraft. With New Horizons still streaming data back from its January encounter with Ultima Thule, Dr. Stern will be able to tell us about the most recent results from this historic mission. Don't miss this - it should be a very engaging and informative talk!

Shadowgram by John Gallagher.

The Hartness House Workshop on Advanced Telescope Making will be held on Thursday, August 1. Richard Berry, author of many astronomy books and former editor of "Astronomy Magazine", will give the key-note/banquet presentation.

Binoculars are NOT just for Beginners Phil Harrington will talk about how to select binoculars good for astronomy.

Almost Free Mirror Coating: Alan Ward will set up his portable coating machine just west of the clubhouse and will be coating attendees' mirrors on Friday and Saturday.

See a Mirror Silvering Demonstration on Saturday, 3:00pm to 5:00pm at the ATM demo tent (north of the T-Shirt sales area).

First Homemade Telescope Certificates will be given to people who bring their first homemade telescope for display on Breezy Hill, and they will be recognized at the Saturday Evening program.

Bring your Solar Scope - We will have designated times and places to set up for solar observing, and by having all the scopes in one area, conventioneers will be able to compare various solar viewing options. The several Stellafane observatories, including our Hale spectrohelioscope, will be operating also (clouds permitting).

2019 Observing Olympics: Complete the observing list at Stellafane, get a pin! For small scopes or binoculars..

A Hands-on Teen Program: We have offered this program since 2014 and it continues to be very popular and successful. The program will teach attendees about how space based instruments work by building functional scientific instruments. This year's mission is still under development and will be announced at a later date.  Requires signup in advance.  Please read the detailed requirements in the Program and then sign up if you can meet them and are interested.

Arlington, MA

http://www.arlingtonastronomy.org 

Jupiter is now high in the southern sky at sundown and Saturn is well up in the South-East, displaying its rings in increasing clarity as it rises higher in the sky. A small sliver of the Moon is setting at dusk, What does this tell us about where the Moon is relative to the Sun?

Arlington Astronomy Nights

Robbins Farm Park

Arlington, MA

http://www.arlingtonastronomy.org 

Saturn has now taken over Jupiter's place of prominence in the Southern sky, ascending as the sky darkens.  As the Earth moves further away from Jupiter, we see it moving more to the West, towards the setting Sun. The Moon has set with the Sun tonight leaving a dark sky, and a chance to spot a star cluster or two.

The Sky at a Glance: July 2019

                 

                                                                 

There is a total solar eclipse on July 2. The path of totality crosses the central and eastern portions of the South Pacific before hitting the coast of Chile. It then slices through Argentina, stopping just as it reaches the outskirts of Buenos Aires.

       

Earth reaches aphelion – its furthest distance from the Sun – at 6:11 PM on July 4. The planet is then 94.5 million miles from the Sun – 3.4% further than at its closest approach in January. Seasons are caused not by variation in our planet’s distance from the Sun but by its axial tilt causing differential solar lighting on its Northern and Southern Hemispheres.

        

There is a partial lunar eclipse on July 16, visible from South America and much of the Eastern hemisphere. It will not be visible from North America.
