  • What’s Up?: Beehive Cluster

    Aug 31, 18 • ndemarino • 5enses, What's up?No CommentsRead More »

    By Adam England On the evening of 6 September, the moon will make a close (1˚04’) approach to one of the oldest studied star clusters, the Beehive Cluster, in the constellation Cancer. Ancient Chinese astronomers labeled the accompanying constellation as the Ghost, with the cluster itself known as Jishi Qi or “exhalation of piled-up corpses” as the breath coming from the ghost. In the Mediterranean civilizations, Hipparchus listed it in his 130 BC star catalog as Nephelion, meaning “Little Cloud,” and the Greek poet Aratus as Achlus or “Little Mist,” while the average Greeks and Romans saw it as a manger from which two neighboring donkeys were eating, with its fuzzy naked-eye appearance being the loose straw. Galileo famously turned his eye and telescope to the cluster in 1609, resolving 40 individual stars in the cluster. Charles Messier took a gander in 1769 and added it to his famous list of sky objects, cataloging it as Messier 44 or M44. To the naked eye, we can see the same thing that our ancient counterparts observed — albeit through a little more light pollution. It will appear as a fuzzy spot in the sky, commonly mistaken for a nebula of gas. But with even the smallest telescope or binoculars, you can begin to see the individual stars. In the center of the cluster are the larger, brighter red giants with the

  • What’s Up?: Sagittarius

    Aug 3, 18 • ndemarino • 5enses, What's up?No CommentsRead More »

    By Adam England August in Northern Arizona gives us some of the best views of the galaxy in which we reside — the Milky Way. So-called since ancient times, the Milky Way is named for its dense clusters of stars that create a “milky” swath across the sky. From our study of other galaxies, we’ve deduced that our own is a barred spiral galaxy with arms of star systems and nebulae stretching up to 180,000 light years from end to end. At the center of the Milky Way — as well as at the center of almost all other known massive galaxies — lies a super-massive black hole named Sagittarius A* (pronounced “Sagittarius A-Star”). The many stars in relatively close proximity to each other and in perpetual orbit around Sagittarius A* form the basis of one of the longest recognized constellations, Sagittarius. Sagittarius is the archer in Babylonian and Greek mythology, usually depicted as a half-man/half-horse, i.e. a centaur, drawing his bow. His arrow points to the heart of Scorpius — the bright red star Antares — should the scorpion ever attempt to attack Hercules after his triumph over the hunter Orion. The most recognizable stars of the constellation form what is known as “The Teapot,” with a handle and spout. The Milky Way rises to the Northwest as a puff of steam rising from the kettle. The handle of

  • What’s Up?: Scorpius

    By Adam England The night skies of Prescott in July offer some amazing sights — at least on the nights that aren’t obstructed by seasonal monsoon storms. One of the easiest constellations to find in the summer months is Scorpius, the Scorpion. With references to the scorpion coming from ancient Babylonian and Hindu cultures, it’s one of the 48 constellations identified in second-century writings by the Greek astronomer Ptolemy. Other cultures viewed the collection of stars differently. In Java, it was seen as both a swan and a leaning coconut tree, while in Hawaii it was the fishing hook of the demigod Maui. Greek mythology tells how Orion, great hunter that he was, boasted that he would kill every animal on Earth. The goddess Artemis offered protection to the creatures, sending a scorpion to do battle with Orion. The scorpion prevailed in the fight, and Zeus raised the pair to the heavens — the triumphant scorpion for his valiant fight, and the hunter as a visual reminder to humans not to be prideful. Easily identifiable in the early evening by looking above the Southeastern horizon, the hooked tail and scorpion’s claws meet at the bright red star Antares, often dubbed the “rival of Mars” for its intense coloring. Other notable features in the constellation include: U Scorpii, the fastest known recurrent Nova (which could brighten to a magnitude of

  • What’s Up?: Planets

    Jun 1, 18 • ndemarino • 5enses, What's up?No CommentsRead More »

    By Adam England The Northern Arizona night skies of late spring/early summer 2018 are dominated by planets. Some of the easiest objects to spot because of their relative proximity to Earth and the Sun, planets are often only outshone by our Moon. Venus, Mars, Jupiter, and Saturn will all be visible throughout the month, each characterized by its unique features. • Venus: This planet likes to hang around the horizons shortly after sunset and/or before sunrise. It’s usually a bright yellowish color due to its dense “Runaway Greenhouse Effect” atmosphere. With a decent telescope or good binoculars, you may see it as a crescent — similar to a quarter Moon. • Mars: Red in color from its oxidized soils and thin atmosphere, this planet rises later in the evening this month and shines until dawn. • Jupiter: The “King of the Planets” always puts on a good show, with the four Galilean moons — Io, Europa, Ganymede, and Calisto — dancing around in space. Sketch what you see on consecutive nights and you’ll notice the moon’s bouncing around as they orbit this gas giant. You might even be able to see the cloud bands wrapping around the planet with storms that could swallow Earth whole. • Saturn: When you first spot this planet, it may look ovular, but as you adjust your focus you’ll see the massive rings extending outward

  • What’s Up?: The Orion Nebula

    May 4, 18 • ndemarino • 5enses, What's up?No CommentsRead More »

    By Adam England One of the most widely recognized constellations in the world is Orion. Ancient cultures from around the world identified this grouping of stars as a giant, shepherd, archer, reaper, and even a deer, pronghorn, or buffalo. Nowadays, it’s most commonly known as “The Hunter,” and is identifiable by some of the brightest stars in the night sky making up his right shoulder (Betelgeuse), left foot (Rigel), and northern end of his thee star belt (Bellatrix). Just below his belt is a tight cluster of stars known as the Trapezium, first observed by Galileo Galilei on Feb. 4, 1617. When the Trapezium is viewed through even the smallest telescopes or binoculars, one can see what is probably the most photographed and studied object in the night sky, the Orion Nebula.

  • What’s Up?: The Pleiades

    Mar 30, 18 • ndemarino • 5enses, What's up?No CommentsRead More »

    By Adam England This month we can see one of the most easily recognizable groupings of stars in the winter sky – The Pleiades. Also cataloged as Messier 45 (M45) or colloquially as The Seven Sisters, it is a star cluster of hot blue stars averaging 444 light years from earth. Used by the Ancient Greeks to determine the Mediterranean sailing season, the name is derived from the mythology of Pleione whose seven daughters were saved from the pursuit of Orion when Zeus first transformed them into doves, and then into stars in the heavens. Nebulosity around the stars is visible with a basic telescope or good binoculars on a clear night.

  • Moon dance: The total solar eclipse of 2017 comes to Prescott (and, you know, everywhere else in the U.S.)

    Jul 25, 17 • ndemarino • 5enses, FeatureNo CommentsRead More »

    By James Dungeon The last time it happened was Feb. 26, 1979. It’s been more than 38 years since that event: a total solar eclipse visible across the contiguous U.S. And, on Monday, Aug. 21, you can see it again — hey, stop staring: that’s the Sun! — from right here in good ol’ Prescott. The partial eclipse lasts two to three hours, though it won’t reach totality here. Prescott’s zenith is a 75 percent eclipse around 10:30 a.m. There’s a deluge of information about the eclipse online, but if you want to experience some local flair, you’d be hard-pressed to find a better gathering than that hosted by the Prescott Astronomy Club. From 9 a.m. through noon, at the Civic Center Amphitheater, 7501 E. Civic Circle, in P.V., there’ll be presentations, displays, hands-on activities, and more. Below, Adam England, publicity coordinator for the Prescott Astronomy Club, shares some info about the event. ***** What does the Prescott Astronomy Club have in store for the solar eclipse? The event, itself, is 9 a.m.-noon on Monday, Aug. 21. There’ll be presentations. One is from members of the Prescott Astronomy Clubs with telescopes with filters so people can view the Sun and Moon in real time. There’s also a local photography club who’ll show how to safely photograph the sun before, during, and after an eclipse, as well as any other time,

  • Prescott Peeps: Russell Chappell

    How did you first get involved in nonprofits in the community? When my wife and I moved to Prescott in December of 2004, we discovered our home was surrounded by birds and wildlife. We thought it would be nice to feed the birds, so I visited Jay’s Bird Barn, where Eric Moore loaded me up with optics, books, seeds and birding information and invited me to the next Prescott Audubon Society meeting, so I guess Eric is ultimately responsible for my relationship with Audubon, and I thank him and blame him for that. As a pilot, I focused on avoiding birds, but I really never studied them. Halfway through that first Audubon meeting, I was planning how to graciously thank them for their hospitality and quietly slip out the door. The chapter’s IBA Coordinator, Karen O’Neil, was giving a presentation and her vocabulary and passion about birds were foreign to me, and I didn’t feel birders and I would be compatible. During a break, Eric introduced me to the chapter president, mentioning my background in computers, aviation and technology. The president asked if I’d be willing to operate their projector at the next meeting. I agreed and was thus committed to a second meeting. The president also mentioned the chapter had CD with a lot of data on it and wondered if I would review it and see if the

  • Get Involved: The Launch Pad Teen Center & Prescott Astronomy Club

    Dec 30, 16 • ndemarino • 5enses, Get InvolvedNo CommentsRead More »

      Get Involved: The Launch Pad Teen Center Who are you and what do you do? I’m Courtney Osterfelt, and I’m the executive director of The Launch Pad Teen Center. We’re a nonprofit youth- and teen-directed center. That means that the teens, mainly 13- to 18-year-olds, who come to The Launch Pad decide what programs and events we do. The center is open 3-6 p.m., Monday through Friday, and teens can come in, do homework, make friends, create art, play games, or make other things happen. We also give grants to teens who want to make changes in the community. We have things like Pin Parties. Basically, they take an art project they want to do from Pinterest, and we provide the art supplies to do it. There are usually 15 to 20 teens. We also have groups like the Q Collective, which includes LGBTQ youth and meets weekly and has social gatherings about once a month. We also have concerts. The music ranges from punk shows to heavy metal and everything in between. Usually attendance for those draws 70 to 100 teens. There’s a suggested donation of $5, and the door fee is split among the bands, so it’s also an opportunity for teen bands to get paid. We also have an internship program and a leadership program, and all of that is free. We also have two summer

  • Astronomy 101: Theoretically speaking

    By Wyatt Frazee “The Big Bang Theory” — great TV show right? The actual scientific theory it’s named for is even wittier. The Big Bang theory is a model that explains how everything, absolutely everything, came into existence. Though illustrative — Bang! Universe! — the name itself doesn’t sound particularly scientific. (It kinda sounds like something you’d say to a toddler who falls down or throws a toy.) That’s because the name was born of sarcasm. A few centuries ago there were two competing scientific theories about how the universe came into being and what it was doing. The rule of the day, the so-called Steady State theory, stated the universe was neither contracting nor expanding. It was, well, static. Albert Einstein himself backed this theory, ultimately leading to his ill-fated cosmological constant. The competing theory stated the universe started as an infinitely small, infinitely hot, infinitely dense matter squished into infinite density, called a singularity. After the singularity’s appearance it began inflating and cooling off, and continues to do so. This idea, the Expanding Universe theory, was pioneered by astronomer Edwin Hubble. As the 20th century wore on, the notion of an expanding universe eclipsed the static model. British astrophysicist Sir Fred Hoyle wasn’t convinced. In the 1950s, while taping a series of TV lectures called “The Nature of the Universe,” Hoyle tried to explain that the universe had
