Free Astronomy Magazine – March-April 2017 Issue Available For Reading And Download

Greetings, fellow astrophiles!

The most recent issue of Free Astronomy Magazine (March-April, 2017) is available for your reading and downloading pleasure at www.astropublishing.com (click the link to go directly to the issue).

Free Astronomy Magazine was featured as the first of a series of articles on great free online content for amateur astronomers (see A Universe Of Free Resources Part 1) and we’ll be keeping track of future publications under the Online Resources category on the CNYO website.

You can find previous Free Astronomy Magazine issues by checking out our Free Astronomy Magazine Category (or look under the Education link in our menu).

For those wanting a quick look at what the issue has to offer, the Table of Contents is reproduced below.

Distant Worlds: What We Know About Extra-Solar Planets And Their Potential For Habitability

Greetings, fellow astrophiles!

I’m pleased to announce that CNYO is co-sponsoring a lecture with the Cazenovia College Science Cafe Committee on one of the great achievements in observational astronomy in the last decade – the discovery and characterization of extra-solar planets (exoplanets). If so inclined, feel free to RSVP on our meetup.com event page. Details below:

Distant Worlds: What We Know About Extra-Solar Planets
And Their Potential For Habitability

Speaker: Dr. Leslie Hebb, Hobart and William Smith Colleges

Date: March 1, 2017

Time: 6:30 to 8:00 pm

Parking: Free on campus after 6:00 p.m., available on Lincklaen, Seminary, Sullivan, and Nickerson Streets

Location: Morgan Room, basement of Hubbard Hall, Cazenovia College

Since the first extra-solar planet was discovered around the star 51 Pegasi, there has been an explosion of research aimed at discovering and characterizing planets around other stars. With the launch of NASA’s Kepler mission, the number of known exoplanets has grown to nearly 5000 including almost 500 multi-planet “solar systems”. Through these and other discoveries, we have learned that exoplanets are ubiquitous throughout the Galaxy, and many planetary systems look very different than our own Solar System. This research has radically transformed our thinking about how our own Solar System in particular and solar systems in general form and evolve. I will discuss how exoplanets are detected and characterized, the current exoplanet census, and our current understanding of how planetary systems form and evolve. I will also discuss how we identify potentially habitable worlds and what future missions are designed to identify and characterize habitability.

CNYO Brochure – An Observational Astronomy Facts And Figures Cheat Sheet

To cut to the downloading chase: Astronomy Facts And Figures Cheat Sheet V6.pdf

Greetings, fellow astrophiles!

Those who’ve ever run an observing session have inevitably faced the most daunting of amateur astronomy outreach questions:

“Woah. How far away is that?!”

In the interest of having a rapid response to that and similar questions, the posted cheat sheet combines as much of the usual information that observers and attendees might want to know as can be fit in not-too-small font into groupings that fit on single pages (10, total).

An important word on the facts: To the very best of ability, all of the information has been checked and double-checked against available data online. To that end, all of the data as presented can be directly attributed to the following websites as of their content on 1 January 2017:

And, of course:

* en.wikipedia.org/wiki/Apparent_magnitude

* en.wikipedia.org/wiki/Stellar_classification

The Observational Astronomy Cheat Sheet contains the following:

Page 1: The only two figures in the document, including the famous “finger how-to” for measuring distances in the night sky and a figure describing right ascension and declination (with values for many objects given in the tables).

Page 2: Moons And Planets – All of the standard information (and descriptions below) about the relative places of planets in the Solar System (distances, masses, temperatures, distances from Sun), then an extra column for our Moon.

Page 3: Best Meteor Showers – All of the categorized Class I, II, and III Meteor Showers throughout the year, including approximate peak dates, times, and directions.

Page 4: Marginal Meteor Showers – All of the categorized Class IV Meteor Showers (these are surely poor meteor showers for observing, but that fact that we’ve catalogued them there tells you how exhaustive astronomers have been in keeping track of periodicities in our day/nighttime sky).

Page 5: Winter And Spring Messier Objects – including abbreviations, NGC labels, types, distances (as best we know them), and Common Names.

Page 6: Summer And Autumn Messier Objects – including abbreviations, NGC labels, types, distances (as best we know them), and Common Names.

Page 7: Northern and Zodiacal Constellations – including family, origin, brightest star, and positional information.

Page 8: Southern Constellations – including family, origin, brightest star, and positional information.

Page 9: Top Asteroids – the best and brightest (and best identified), including distances, discovery information, and magnitudes (as available).

Page 10: Stars – the Top 50 brightest (with our Sun at its rightful position as #1), including constellation, magnitudes, distances, and mass and positional information.
