NASA Space Place – Observe The Moon

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 October, 2018.

2013february2_spaceplaceThis year’s International Observe the Moon Night is on Oct. 20. Look for astronomy clubs and science centers in your area inviting you to view the Moon at their star parties that evening!

On Oct. 20, the 11-day-old waxing gibbous Moon will rise in the late afternoon and set before dawn. Sunlight will reveal most of the lunar surface and the Moon will be visible all night long. You can observe the Moon’s features whether you’re observing with the unaided eye, through binoculars or through a telescope.

Here are a few of the Moon’s features you might spot on the evening of October 20:

Sinus Iridum — Latin for “Bay of Rainbows” — is the little half circle visible on the western side of the Moon near the lunar terminator—the line between light and dark. Another feature, the Jura Mountains, ring the Moon’s western edge. You can see them catch the morning Sun.

Just south of the Sinus Iridum you can see a large, flat plain called the Mare Imbrium. This feature is called a mare — Latin for “sea” — because early astronomers mistook it for a sea on Moon’s surface. Because the Moon will be approaching full, the large craters Copernicus and Tycho will also take center stage.

Copernicus is 58 miles (93 kilometers) across. Although its impact crater rays—seen as lines leading out from the crater—will be much more visible at Full Moon, you will still be able to see them on October 20. Tycho, on the other hand, lies in a field of craters near the southern edge of the visible surface of the Moon. At 53 miles (85 kilometers) across, it’s a little smaller than Copernicus. However, its massive ray system spans more than 932 miles (1500 kilometers)!

And if you’re very observant on the 20th, you’ll be able to check off all six of the Apollo lunar landing site locations, too!

In addition to the Moon, we’ll be able to observe two meteor showers this month: the Orionids and the Southern Taurids. Although both will have low rates of meteors, they’ll be visible in the same part of the sky.

The Orionids peak on Oct. 21, but they are active from Oct. 16 to Oct. 30. Start looking at about 10 p.m. and you can continue to look until 5 a.m. With the bright moonlight you may see only five to 10 swift and faint Orionids per hour.

If you see a slow, bright meteor, that’s from the Taurid meteor shower. The Taurids radiate from the nearby constellation Taurus, the Bull. Taurids are active from Sept. 10 through Nov. 20, so you may see both a slow Taurid and a fast Orionid piercing your sky this month. You’ll be lucky to see five Taurids per hour on the peak night of Oct. 10.

You can also still catch the great lineup of bright planets in October, with Jupiter, Saturn and Mars lining up with the Moon again this month. And early birds can even catch Venus just before dawn!

“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.

* 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:

* And, finally, we finish up the circumpolar constellations with Camelopardalis before going briefly into what circumpolar constellations are in the November article:

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

* We extend last month’s discussion of Messier Objects by briefly discussing the objects Messier was most keen on finding – comets. Many thanks to Brad Loperfido for the kind reprint permissions of his excellent Comet 41P/Tuttle-Giacobini-Kresak et al. catch (below).

* We continue our look north with Ursa Minor, the second of six constellations that are always visible in the nighttime sky from our latitude (readers then can guess where the next four articles are headed).

* This month, we await the Lyrid Meteor Shower, which peaks on the early morning of April 22nd. The Lyrids peak in the presence of a sliver of a waning crescent Moon – this is excellent news for observers annoyed by the many washed-out 2016 meteor showers, as the Moon will not be bright enough to dull bright Lyrid trails.

Caption: The Lyrid Meteor Shower radiant, roughly between the bright star Vega and the southern elbow of Hercules. Pending the skies and brightness, you may even be able to see Comet 41P/Tuttle-Giacobini-Kresak between the head of Draco and arm of Hercules that night. Click for a larger view.
