Bob Piekiel Hosts Observing Sessions At Baltimore Woods (And More!) – 2017 Observing Schedule

This event list will be added to as the year progresses. Check back often!

I’m pleased to have obtained the official schedule for Bob Piekiel’s growing observing and lecture programs for the 2017 season and have added them to the CNYO Calendar. For those who have not had the pleasure of hearing one of his lectures, attending one of his observing sessions, or reading one of his many books on scope optics (or loading the CD containing the massive Celestron: The Early Years), Bob Piekiel is not only an excellent guide but likely the most knowledgeable equipment and operation guru in Central New York.

Baltimore Woods:

* January 20 (Fri.)/21 (Sat. weather alternate), 6:30-8:30 p.m.

Winter Skies at their finest, and great views of a large, crescent Venus. No other area of the sky contains as many bright stars, clusters, and nebulae as the area surrounding the winter constellation Orion!

* February 10 (Fri.)/No weather backup, 6:30-8:30 p.m.

A penumbral eclipse of the moon. This is kind of an odd-ball program, as most penumbral lunar eclipses go unnoticed. The moon passes through the earth’s partial shadow and turns a bit of a dim brown color. Interesting to see IF you know what you’re looking at (plus winter skies, but the faint objects will be obscured by the moon).

* February 18 (Sat.)/19 (Sun. weather alternate), 1:00-3:00 p.m.

Solar viewing program, plus great daytime views of Venus and the moon.

* March 3 (Fri.)/4 (Sat. weather alternate), 7:00-9:00 p.m.

Goodbye to winter skies, Maybe still a peek at Venus, and Jupiter will be rising in the east.

* March 31 (Fri.)/April 1 (Sat. weather alternate), 6:00-9:00 p.m.

This is our best chance to see the elusive planet Mercury, plus Jupiter will be rising as Mercury will be setting. Spring skies will be replacing the Winter constellations.

* May 19 (Fri.)/20 (Sat. weather alternate), 8:30 – 10:30 p.m. (meetup.com event)

Spring skies offer a large number of galaxies to be viewed, plus interesting star clusters, and the giant planet Jupiter will be visible all evening. We may also get a look at Saturn later in the program.

* June 16 (Fri.)/17 (Sat. weather alternate), 9:00 – 11:00 p.m. (meetup.com event)

Just because it gets dark late doesn’t mean we can’t enjoy the night sky! Saturn and Jupiter will be easily visible, plus an early look into the heart of our Milky Way Galaxy near the end of the program.

* July 21 (Fri.)/22 (Sat. weather alternate), 8:00 – 11:00 p.m. (meetup.com event)

Summer skies at their finest, looking at the rich star fields near the center of the Milky Way, plus a farewell to Jupiter. Saturn will be visible all evening, and maybe even a peek at Mercury early.

* August 12 (Sat.)/13 (Sun. weather alternate), 8:30 – 11:00 p.m. (meetup.com event)

The annual Perseid meteor shower, one of the year’s finest. Plus great views of the heart of our milky Way galaxy, and the ringed planet Saturn. Bring a lawn chair or blanket to sit back and watch for meteors while not looking through a telescope. We may also be able to get good views of Neptune.

* August 26 (Sat.)/27 (Sun. weather alternate), 1:00 – 3:00 p.m.

Solar observing! Using specially-filtered telescopes, come and see our nearest star as you’ve never seen it before. View sunspots, solar flares, and magnetic fields on the sun’s surface.

* September 15 (Fri.)/16 (Sat. weather alternate), 7:30 – 9:30 p.m.

Goodbye to summer, hello to fall skies and a good view of Uranus and Neptune, our two outermost planets that often go overlooked. Our last chance to see some of the summer Milky Wand its bright clusters.

* October 20 (Fri.)/21 (Sat. weather alternate), 7:30 – 9:30 p.m.

Fall skies, with their galaxies and clusters, plus great views of Uranus and Neptune, and maybe a few meteors from the Orionids, which peak about this time every year.

* November 17 (Fri.)/18 (Sat. weather alternate), 7:00 – 9:00 p.m.

Hello to winter skies. A 1st-quarter moon starts the show, and as it gets darker, a first look at the area of the sky preceding Orion, with its many galaxies and brighter star cluster. Still good views of Uranus and Neptune. PLUS the Leonid meteor shower!

* December 13 (Wed.)/14 (Thur. weather alternate), 7:00 – 10:00 p.m.

The Geminid meteor shower – “Nuff-Said.” The Geminids are caused by asteroid Phaethon 3200, and unlike most other meteor showers, begin their display much earlier in the evening, so no need to wait til pre-dawn! Also our first views of the area surrounding Orion, with some of the brightest nebulae and clusters visible in the northern hemisphere.

Green Lakes:

* January 14 (Sat.)/15 (Sun. weather alternate), 1:00-3:00 p.m.

Come view our nearest star, the sun, close up in special telescopes that give interesting views of solar flares, eruptions, and sunspots. At the parking lot behind the main office building.

* February 17 (Fri.)/18 (Sat. weather alternate), 7:00-9:00 p.m.

Come see the winter skies at their finest! The area around the constellation of Orion has more bright stars, nebulae, and clusters than any other part of the sky. At the parking lot behind the main office.

* July 7th (Fri.), 7:00-9:00(?)p.m. – CHOOSING AND USING A TELESCOPE Workshop

Got a telescope as a gift but not sure how to make use of it? Thinking about purchasing one and wondering what are the best choices? Have a telescope and want to be able to take great pictures through it? Want to learn more about the night sky? Come to our first telescope workshop (Bring your own scope if you have one!) and let our astronomer Barefoot Bob show you the ins- and outs- of these wonderful pieces of equipment.

– This program will take place rain or shine, clouds or clear skies. It will be at the nature center (Susan – you may want to clarify the location here) if raining and at the field next to the Frisbee golf course if dry.

– Space will be limited, so please pre-register. This program takes place one week prior to our first public astronomy observing program which is scheduled for Friday evening July 14th.

* July 14 (Fri.)/15 (Sat. weather alternate), 7:30-10:30 p.m.

See the summer skies as we look directly into the heart of our Milky Way galaxy, plus the giant planets Jupiter and Saturn. We may also get a peek at Mercury just before sunset!

* August 18 (Fri.)/19 (Sat. weather alternate), 8:00-10:00 p.m.

Summer skies one more time, and the rich star fields of the core of our Milky Way Galaxy, along with the planets Jupiter, Saturn, and Neptune.

* November 5 (Sunday), 1:00-3:00 p.m.

A telescope workshop! This will include some outdoor hands-on work, but will start indoors with some explanation of telescope types, eyepieces, mounts, and camera attachments.

Clark Reservation:

* July 28 (Fri.)/29 (Sat. weather alternate)

There is a 1st-quarter moon low in the sky that will set and leave the skies dark for the later half of a program. Mercury, which we hardly ever get a chance to easily see, is at best viewing for the summer, as well as good views of Jupiter and Saturn. This is also the time to see the summer skies at their finest, as we look directly into the heart of the Milky Way.

NASA Space Place – Dimming Stars, Erupting Plasma, And Beautiful Nebulae

Poster’s Note: One of the many under-appreciated aspects of NASA is the extent to which it publishes quality science content for children and Ph.D.’s alike. NASA Space Place has been providing general audience articles for quite some time that are freely available for download and republishing. Your tax dollars help promote science! The following article was provided for reprinting in November, 2016.

By Marcus Woo

2013february2_spaceplaceBoasting intricate patterns and translucent colors, planetary nebulae are among the most beautiful sights in the universe. How they got their shapes is complicated, but astronomers think they’ve solved part of the mystery—with giant blobs of plasma shooting through space at half a million miles per hour.

Planetary nebulae are shells of gas and dust blown off from a dying, giant star. Most nebulae aren’t spherical, but can have multiple lobes extending from opposite sides—possibly generated by powerful jets erupting from the star.

Using the Hubble Space Telescope, astronomers discovered blobs of plasma that could form some of these lobes. “We’re quite excited about this,” says Raghvendra Sahai, an astronomer at NASA’s Jet Propulsion Laboratory. “Nobody has really been able to come up with a good argument for why we have multipolar nebulae.”

Sahai and his team discovered blobs launching from a red giant star 1,200 light years away, called V Hydrae. The plasma is 17,000 degrees Fahrenheit and spans 40 astronomical units—roughly the distance between the sun and Pluto. The blobs don’t erupt continuously, but once every 8.5 years.

The launching pad of these blobs, the researchers propose, is a smaller, unseen star orbiting V Hydrae. The highly elliptical orbit brings the companion star through the outer layers of the red giant at closest approach. The companion’s gravity pulls plasma from the red giant. The material settles into a disk as it spirals into the companion star, whose magnetic field channels the plasma out from its poles, hurling it into space. This happens once per orbit—every 8.5 years—at closest approach.

When the red giant exhausts its fuel, it will shrink and get very hot, producing ultraviolet radiation that will excite the shell of gas blown off from it in the past. This shell, with cavities carved in it by the cannon-balls that continue to be launched every 8.5 years, will thus become visible as a beautiful bipolar or multipolar planetary nebula.

The astronomers also discovered that the companion’s disk appears to wobble, flinging the cannonballs in one direction during one orbit, and a slightly different one in the next. As a result, every other orbit, the flying blobs block starlight from the red giant, which explains why V Hydrae dims every 17 years. For decades, amateur astronomers have been monitoring this variability, making V Hydrae one of the most well-studied stars.

Because the star fires plasma in the same few directions repeatedly, the blobs would create multiple lobes in the nebula—and a pretty sight for future astronomers.

TACNY Junior Cafe Scientifique: “Think Fast! The Rapid Motions Of Everyday Liquids”

Saturday – November 19, 9:30-11:00am

Please RSVP to jrcafe@tacny.org

Milton J Rubenstein Museum of Science & Technology – Syracuse, NY

Speaker

Joseph D. Paulsen, Ph.D., Assistant Professor of Physics, Department of Physics, Syracuse University

Talk Overview

What if you could see the world around you 5,000 times slower, so that a second lasted more than an hour? Using high-speed cameras that record up to 1,000,000 photos per second, we can “slow down” time as we watch the splashing of a raindrop in a puddle, or the joining of oil droplets at the surface of a bowl of soup. These images are not only beautiful, but also allow us to better understand the physics of fluids.

Biography

2016nov10_paulsenJoey Paulsen is an Assistant Professor of Physics at Syracuse University. His research investigates the wrinkling, crumpling, and folding of thin elastic sheets, the arrangements of solid particles in a sludge, and the rapid motions of liquids due to the surface tension that holds droplets together. Joey earned his Ph.D. in Physics from the University of Chicago and then moved east for a postdoc at the University of Massachusetts, Amherst. He joined the Physics Department at SU in the Fall of 2015, where he is growing his research lab and teaching in the classroom. Outside of the lab, he enjoys spending time with his wife, savoring a good cup of coffee, and doing various low-risk outdoor activities, including biking, canoeing, camping, and hiking.

“November Stargazing in Upstate NY” Article Posted To newyorkupstate.com And syracuse.com

Greetings, fellow astrophiles!

The latest article in the series, “November Stargazing in Upstate NY: Catch the sometimes roaring Leonids,” has just been posted to newyorkupstate.com and syracuse.com.

This month, we introduce the open clusters using the Hyades and Pleiades, then focus on Cygnus the Swan and finding the small, distant open clusters M29 and M39. Orion, Taurus, and the Pleiades are up all the earlier this month, bringing the best of winter to us just early enough to take in some great telescope views.

This month also includes event announcements for several NY astronomy clubs with posted November observing sessions. I’m hoping to have permissions from several other clubs to post their announcements as well to fill out the within-one-hour’s-drive map of NY public sessions (sadly perfect timing, given that winter often means observing hibernation).
