Astronomy - Ch. 17: The Nature of Stars (34 of 37) Determining Stellar Radius of Sirius - Video
To gain perspective on ones life, sometimes a look skyward into the inky nocturnal abyss is all it takes to realize just how small we really are.
Life is more about just meeting a certain deadline at work, said Dominic Lesnar, the president of the Astronomy Club of Asheville. Its great to see the bigger picture of how the world operates. This is the satisfaction of knowing your place in the universe and seeing how dynamic the natural world is.
The Astronomy Club invited a whole lot of people to look up when it celebrated its second public stargazing event Jan. 24 at UNC Ashevilles Lookout Observatory, a newly christened facility that members hope will bring further interest in the heavens throughout the area. The event drew 175 science lovers an extraordinary 300 people were initially expected and filled a waiting list just as long, but the viewing was delayed a day due to cloudy skies.
On the night of the viewing, weather cleared and visitors were treated to crystal-clear views of Venus, the moon, the Andromeda galaxy and the Orion nebula. Exclamations of ooh and ahh permeated the viewing structure as stargazers young and old took a peekthrough the telescopes.
The club had its first official public stargazing at the new Lookout Observatory facility at the top of the hill on the UNCAcampus on Nov. 14. The January viewing was the first fully publicized event at the observatory, which is complete with warming room and four permanent state-of-the-art telescopes. The building and most of whats in it was funded by the club and shares usage with the university.
Its a 50/50 partnership with the university. They provide the infrastructure, we provide the funding for the equipment, said Lesnar. The interest for a public observatory has always been there; now people can go and be treated to a guided tour of the night sky, all minutes from their homes.
The Astronomy Club has grown from a casual gathering of about 10people half a decadeago to more than 100 members under outgoing President Bernard Arghiere. The primary objective is outreach, educating individuals as well as school groups on the wonders of the universe through talks, gatherings, school events and firsthand observations through some very nice telescopes.
In addition to events at Lookout Observatory, stargazing events are held at public places around Asheville about twice a month, weather permitting.
Thats Sirius, the brightest star in the sky, club member Jim Hornaday pointed out during a recent public club gathering at Tanbark Ridge overlook on the Blue Ridge Parkway.
Nope, the brightest star is the sun! shot back another stargazer and club member, Dennis Wilde, from behind his telescope.

Astronomy Club of Asheville educates, amazes at UNCAs Lookout Observatory
For this year, state astronomy agency PAGASA is working to make astronomy more accessible to people via National Astronomy Week (NAW).
The theme for this year's NAW is "Reaching Our People: Transferring Knowledge in Astronomy," acting administrator Vicente Malano said.
Malano said this year's NAW from Feb. 16 to 20 will include:
- free Planetarium shows - stargazing and telescoping sessions at PAGASA observatory - star party contest for high school in Laoag City - seminar-workshops on astronomy for public school teachers in Laoag City - free mobile planetarium shows on Feb. 17 and 18 in Laoag - free astronomy posters for visiting schools at Planetarium and Astronomical Observatory
Admissions to the shows will be on a first-come, first-served basis.
Planetarium shows are from 8 a.m. to 5 p.m., while lecture and telescoping sessions will start 7 p.m. Joel Locsin/LBG, GMA News

North Wales astronomy buff Brian Woosnam has been busy capturing images of the night sky this January.
Here are his tips for what to look out for in the heavens during February.
The stars of winter are now beginning to wane and those of spring are eager to take their place.
Orion the hunter is still well placed in the early evening but his position of dominance is now starting to ebb away, and as the sun continues to rise higher so the evening sky gets lighter.
The Moon phases

Last quarter 12th
First quarter 25th
The Planets
The planet Venus is a brilliant object in the evening western sky in Aquarius along with Mars about an hour after sunset.

If you have recently received a telescope as a holiday gift, it is likely that your very first target will be our nearest neighbor in space: the moon.
When is the best time to observe the moon with a telescope? Most astronomy neophytes might say it is when it's at full phase, but that's probably the worst time to look at it! When the moon is full it tends to be dazzlingly bright as well as flat and one-dimensional in appearance.
In contrast, the interval when the moon is at or just past first quarter phase, or at or just before last quarter phase, is when we get the best views of the lunar landscape right along the sunrise-sunset line or terminator. The terminator can also be defined as that variable line between the illuminated portion and the part of the moon in shadow.
Along with the fact that a half moon offers more viewing comfort to the eye as opposed to a full moon, using a telescope with just small optical power (magnifications of 20- to 40-power), or even with good binoculars, we can then see a wealth of detail on its surface. Around those times when the moon is half-lit or gibbous phase, those features lying close to the terminator stand out in sharp, clear relief. [The Moon: 10 Surprising Lunar Facts]
In contrast to a half moon, a full moonis almost completely illuminated, especially right around its center; the sun shines straight down even into all the microscopic crevices and except for perhaps around its immediate edges, you will find no visible shadows at all.
The moon will arrive at last quarter phase on Thursday, Feb 11, at 10:50 p.m. EST (0350 Feb. 12 GMT). That will be the moment when the moon's disk is exactly 50-percent illuminated. Lunar mountains will be visible as the sun lights them from the right.
How does a last quarter moon's brightness compare with a full moon? You might think it would be half as bright as a full moon, but in reality astronomers tell us that the last quarter (or first quarter) moon is only 1/11th as bright as full. This is due to the fact that, a half moon is heavily shadowed, even on its illuminated half. And believe or not, it isn't until just 2.4 days before full that the moon actually becomes half as bright as full!
Finally, have you ever noticed that when artists portray the moon, they invariably seem to show it as either a slender crescent or full?
Half-moons are shown far less frequently, while gibbous moons are rarely depicted at all. The word gibbous is derived from the Latin word "gibbus" meaning, "hump." An unusual word to be sure, but in describing the moon between half and full, it's the correct term.
Yet interestingly, the gibbous moon, the phase of the moon that we are now seeing in our current evening sky is the most-seen phase. It occurs for the half month between first and last quarter (although for many it looks "full" for two or even three nights around the time of full moon).
