Midpark Planetarium

There are not many other high schools with their own planetarium. The planetarium is a room with a 24' dome for a ceiling. The dome serves as a projection screen. A star projector is located in the center of the room which projects stars onto the dome. When the lights are dimmed, it seems as if one is outside looking at the real stars. The effect can range from a light polluted city sky to the intense sky of the country or desert. The Sun, Moon and planets can also be included in the projections. A coordinate system and other visual effects can also be superimposed on the star field.

Midpark's astronomy classes often visit the planetarium. Other Midpark teachers can sign up for a planetarium visit as appropriate for their subject matter. Many of the planetarium visits are from other schools in the Berea City School District. Visitors range from second to sixth graders. Various grades in this range include one or more planetarium visit as part of their science curriculum.

Several public evening shows are offered throughout the school year at the Midpark planetarium. These are coordinated through the district's Community Education Department. Please contact them for dates, times and sign-up information.

If you are interested in astronomy you may wish to follow the link elsewhere on the Alumni web page to an astronomy information listing. This gives some starting points as to what to look for in the night sky.

September/October 2008 Highlights

    ·   OK, now, let’s remember not to believe everything in email forwards. The recent internet flurry about Mars is a case in point. Sure, Mars made close approaches in 2004 and again in 2005. At those approaches, Mars appeared bright, like a very bright star. It definitely did not look as bright or as big as a full Moon as claimed in the email that seems to circulate every year around this time. I’m still wondering where that hoax came from.

    ·   The planet Jupiter is very brightly visible in the south and southwest sky after sunset. It will continue to sink lower as the weeks progress. A small telescope, or even binoculars, if held steadily, can offer you a view of Jupiter’s four largest moons. Jupiter is above the teapot shape of the constellation Sagittarius.

    ·   For the first two weeks of September, Venus, Mercury and Mars are very near the western horizon just after sunset. Venus is quite bright, but Mercury and Mars are quite dim and binoculars may be necessary. On September 1 a very thin crescent Moon is below them. On tne next night the crescent Moon has moved to their left.

    ·   On September 10 and 11, Venus and Mars reach conjunction, a very close approach. Very dim Mars is just below Venus. The star Spica (in the constellation Virgo) is to their left.

    ·   By the middle of September, Venus moves a bit higher in the west, while Spica, Mars and Mercury are sinking lower, soon to move below the horizon. Venus will continue to rise higher and higher as the weeks progress. It will move closer and closer to Jupiter. At the end of November, they will form a spectacular conjunction.

    ·   Saturn will be visible very near the eastern horizon before sunrise. Regulus, in the constellation Leo, is to the upper right of Saturn.

    ·   The Orionid Meteor Shower makes its yearly appearance for those with a dark sky.

    ·   The summer sky begins to slowly move into the fall sky.

    ·   The Summer Triangle is still easily visible for many more weeks, even into winter. Look for the stars Deneb at the upper left, Vega to its right and Altair. The Summer Triangle points roughly south. Deneb is the top of the Northern Cross, (official name Cygnus, the swan.) Vega is part of Lyra the harp and Altair is part of Aquila the eagle. Vega is nearly overhead for much of the month of September.

    ·   Facing south, look slightly to the left of the Summer Triangle for a very dim group of stars. This is Delphinus the dolphin.

    ·   In the northeast we can view the constellation Cassiopeia, which is shaped like the letter “W”.

    ·   The fourth line of the “W” that forms Cassiopeia points “up” to the crooked house shape of Cepheus the king.

    ·   The third line of the “W” points “downward” toward the Great Square of Pegasus the winged horse.

    ·   The corner of the Great Square nearest Cassiopeia begins a line of stars that underlines the “W.” This line of stars is Andromeda, the daughter of Cassiopeia and Cepheus.

    ·   If you are observing from a dark location you may be able to see the Andromeda Galaxy which looks like a very dim Moon-sized fuzzy patch below the “W” and above Andromeda. Binoculars will probably be necessary unless you are observing from a very dark location.

    ·   Following the second line of the “W” of Cassiopeia “downward” leads to the constellation Perseus, the hero.

    ·   If you have a very good view of the horizon or wait until later in the evening you may be able to see the Pleiades, or Seven Sisters, which is a dim but easily visible cluster of stars.

    ·   In the west look for the bright star Arcturus which is the bottom of the kite shape of Bootes the shepherd. If you are observing from a fairly dark sky, look above Arcturus for the faint little constellation Corona Borealis, the Northern Crown. It is a semicircle of dim stars. The semicircle opens to the upper right.

    ·   To the right of Arcturus is the Big Dipper, (official name Ursa Major, the Big Bear.) The handle of the Big Dipper “arcs” to Arcturus. At this time of year, the big dipper is moving lower and lower in the northwest.

    ·   Between the kite shape of Bootes and the big bear, is a dim constellation called Canes Venatici. These are the hunting dogs.

    ·   The Pointer Stars of the Big Dipper point to Polaris, the North Star which is the end of the handle of the Little Dipper, Ursa Minor. The stars of Ursa Minor are fairly dim and difficult to spot. Many wrongly believe that the North Star appears very bright. However, from our vantage point on Earth, the North Star appears rather dim.

    ·   In the southwest near the horizon is the reddish star, Antares, the heart of Scorpius the scorpion.

    ·   As we progress into October, the star Capella, in the constellation Auriga is visible in the northeast.

    ·   If you are observing from a very dark area, the Milky Way may be visible. The Milky Way, our galaxy, looks like a cloudy or fuzzy patch through the sky. Every individual star we see is actually a part of the Milky Way. When we see the fuzzy patch through the sky, we are looking toward the densest, most intense parts of our galaxy.

September/October 2008 Astronomical Events

    ·   Sept. 2  Just after sunset, look for the star Spica (in the constellation Virgo) to the upper left of the Moon very low near the western horizon. To their lower right, you may be able to spot three planets. Venus will be very bright. Next in brightness is Mercury. Even dimmer is Mars. Binoculars will probably be necessary to see all of these.

    ·   Sept. 6  The Moon has moved to the upper left. It is just below the star Antares, the heart of Scorpius, the scorpion.

    ·   Sept. 8  The Moon has moved to the right of very bright Jupiter.

    ·   Sept. 9  The Moon has moved to just below Jupiter.

    ·   Sept. 10  Mercury is at its greatest elongation for this appearance. That is, it is at its farthest distance from the Sun as seen from Earth. Even though it is at greatest elongation, Mercury is still very near the horizon and difficult to spot. It is very near the bright planet Venus. Binoculars will help you spot Mercury.

    ·   Sept. 12  The planet Uranus is at opposition. That is, it is opposite the Sun as seen from the Earth. It will rise as the Sun sets. It is so dim, that it looks like a faint blue-green dot.

    ·   Sept. 14  The Moon will barely miss Uranus.

    ·   Sept. 22  Autumn officially arrives at 11:44 a.m. EDT. At this moment, called the autumn equinox, the Sun is crossing the Equator heading south for the winter. This event defines the start of fall in the northern hemisphere and spring in the southern hemisphere.

    ·   Sept. 26 The Moon has moved to about one degree from the star Regulus (in the constellation Leo the lion) near the eastern horizon. One degree is about a finger-width at arm’s length. They will rise about two hours before sunrise.

    ·   Sept. 27  The Moon has moved to the right of Saturn near the eastern horizon before sunrise.

    ·   Oct. 2  The Moon has moved to the “evening” side of the Sun. It is now visible well to the left of very bright Venus very near the southwest horizon just after sunset.

    ·   Oct. 4  The Moon has moved to the left of the star Antares. Antares is the brightest star in the constellation Scorpius the scorpion. Antares represents the heart of the scorpion.

    ·   Oct. 6  The Moon has moved near the very brilliant planet Jupiter.

    ·   Oct. 14  The Orionid Meteor Shower may begin to be visible. Please see the Oct. 21 note.

    ·   Oct. 16/17  The Moon has moved very near the dim little Pleiades star cluster, also known as the Seven Sisters. They will rise in the evening of the 16th. From some parts of North America, the Moon will move in front of some of the Pleiades stars.

    ·   Oct. 21  The peak of the Orionid Meteor Shower occurs. Meteor showers occur when the Earth travels through an area near which a comet has traveled. The debris left by the comet burns as it enters our atmosphere. These are shooting stars, or more correctly, meteors. Meteor showers are, at times, visible for a week or so before and after their peak. The direction to watch is wherever your sky is darkest. With a good dark sky, you may be able to spot a meteor every few minutes.

    ·   Oct. 22  Mercury is at its greatest elongation for this appearance. That is, it is at its greatest distance from the Sun as seen from Earth. Even though Mercury is at its greatest elongation, it is still difficult to spot, very near the eastern horizon, about 45 minutes before sunrise.

    ·   Oct. 23  The Moon has moved to above and right of the star Regulus, the dot in the backward question mark of Leo the lion before sunrise. The planet Saturn is below them.

    ·   Oct. 24  The Moon has moved to the upper right of Saturn before sunrise.

    ·   Oct. 25  The Moon has moved to the lower right of Saturn before sunrise.

    ·   Oct. 26  With binoculars, you might be able to spot Mercury to the lower left of the Moon near the eastern horizon before sunrise.

    ·   Oct. 27 With binoculars, you might be able to spot Mercury to the upper left of the Moon near the eastern horizon before sunrise.

    ·   Oct. 31  The Moon has moved just to the left of the Moon near the southwest horizon just after sunset. Very bright Venus is above them.

    ·   Happy Halloween!

Have a great autumn season!
