“Planet 9 From Outer Space” – Thursday, April 19 At Liverpool Public Library

Greetings, fellow astrophiles!

And apologies for the short-ish notice. This is not a showing of the movie “Plan 9,” but risks being just as cheesy. CNYO makes its yearly (if not more often) return to LPL this Thursday with a lecture that actually overlaps nicely with a lecture topic from a few years back that was presented at a CNY Skeptics meetings – We step out from our discussion of Ceres and Pluto into a discussion of Pluto and the theorized Planet IX (not to be confused with Planet X). As always, we check on the state of the binocular loaner program as well, with hopes that all have been reserved and none are available.

Link details can be found at calendar.lpl.org

Pluto had a remarkably good and lucky run as the 9th planet in our Solar System. Its demotion to dwarf planet status in late 2006 was due to a number of factors, driven largely by the discovery that Pluto is not alone either in size or in location out beyond Neptune’s orbit. Modern telescopes have discovered numerous dwarf planets out in the Kuiper Belt – a region of the Solar System for which Pluto is now the most famous member. By determining the orbits of these distant objects, astrophysicists have even made the prediction that something much larger in size must be lurking in the distance – large enough to qualify as a true planet if and when it is officially observed.

NASA Space Place – Snowy Worlds Beyond Earth

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 December, 2017.

The Space Place article format has changed recently, including more embedded images. To simplify the posting process, a PDF version of the article is provided below, with a snippet of the article reproduced below it.

By Linda Hermans-Killiam


There are many places on Earth where it snows, but did you know it snows on other worlds, too? Here are just a few of the places where you might find snow beyond Earth:

A Moon of Saturn: Enceladus

Saturn’s moon, Enceladus, has geysers that shoot water vapor out into space. There it freezes and falls back to the surface as snow. Some of the ice also escapes Enceladus to become part of Saturn’s rings. The water vapor comes from a heated ocean which lies beneath the moon’s icy surface. (Jupiter’s moon Europa is also an icy world with a liquid ocean below the frozen surface.) All of this ice and snow make Enceladus one of the brightest objects in our solar system.
