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.

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.

“Upstate NY Stargazing In October” Article Posted To newyorkupstate.com And syracuse.com

Greetings, fellow astrophiles!

The latest article in the Upstate NY Stargazing series, “Upstate NY stargazing in October: The Orionids, International Observe the Moon Night,” has just been posted to newyorkupstate.com and syracuse.com.

Direct Links: newyorkupstate.com and syracuse.com

* Included this month are a reminder/announcement about Kopernik AstroFest 2017 (Oct. 13/14), International Observe the Moon Night on October 28th, and the Orionids:

The Orionids are the most prominent meteor shower in October, but ride near the bottom of the top-10 list of active showers for the year. Observers simply interested in seeing any shooting stars do benefit from the Orionids peaking at a time of year when a number of less significant meteor showers are also active, including one of the Geminids and two Taurids showers. This year, the grouping of active showers around the Orionids peak benefit greatly from the absence of the Moon during the 20th-21st peak.

* With Orion out and about at a reasonable hour, the Orion-star-finder has been brought back from the UNY Stargazing archives:

Red = belt stars to Sirius and Canis Major; Orange = Rigel and belt center to Castor and Pollux in Gemini; Yellow = Bellatrix and Betelgeuse to Canis Major; Green = Belt stars to Aldebaran and Taurus; Blue = Saiph and Orion’s head to Capella in Auriga.

* The pre-sunrise mornings continue to provide excellent planetary viewing of Mars and Venus, with several notable arrangements occurring this month:
