In one myth, Orion boasted he would kill all the wild animals on the earth. But, the earth goddess Gaia, who was the protector of all animals, produced a gigantic scorpion, whose body was so heavily encased that Orion was unable to pierce through the armour, and was himself stung to death. His companion Artemis was greatly saddened and arranged for Orion to be immortalised among the stars. Scorpius, the scorpion, was placed on the opposite side of the sky so that Orion would never be hurt by it again. To this day, Orion is never seen in the sky at the same time as Scorpius.

This is Polaris, the Pole (or North) Star. Note that it is not the brightest star in the sky, a common misconception. Below and to the right are two prominent but fainter stars. These are Kochab and Pherkad, the Guardians of the Pole. Look carefully and you will notice that Kochab is slightly orange when compared to Polaris.

It consists of a humorous 24-minute show and educator’s package. The Orion Educator’s Guide is designed for Planetarians, Teachers, and parents. The information is researched, organized, and laid out so that the educator need not spend hours coming up with lesson plans or labs. This has already been accomplished by certified educators. The guide is written to alleviate the fear of space and the night sky (that many elementary and middle school teachers have) when it comes to that section of the science lesson plan. It is an excellent tool that allows the parents to be a part of the learning experience. The guide is devised in such a way that there are plenty of visuals to assist the educator and student in finding the Winter constellations.

    GIANT PLANET MIGRATION THROUGH THE ACTION OF DISK TORQUES AND PLANET-PLANET SCATTERING Althea V. Moorhead1 and Fred C. Adams1,2 1Michigan Center for Theoretical Physics Physics Department, University of Michigan, Ann Arbor, MI 48109 2Astronomy Department, University of Michigan, Ann Arbor, MI 48109 ABSTRACT This paper presents a parametric study of giant planet migration through the com- bined action of disk torques and planet-planet scattering. The torques exerted on plan- ets during Type II migration in circumstellar disks readily decrease the semi-major axes a, whereas scattering between planets increases the orbital eccentricities ǫ. This paper presents a parametric exploration of the possible parameter space for this migration scenario using two (initial) planetary mass distributions and a range of values for the time scale of eccentricity damping (due to the disk). For each class of systems, many realizations of the simulations are performed in order to determine the distributions of the resulting orbital elements of the surviving planets; this paper presents the results of 8500 numerical experiments. Our goal is to study the physics of this particular mi- ∼ gration mechanism and to test it against observations of extrasolar planets. The action of disk torques and planet-planet scattering results in a distribution of final orbital ele- ments that fills the a ǫ plane, in rough agreement with the orbital elements of observed − extrasolar planets. In addition to specifying the orbital elements, we characterize this migration mechanism by finding the percentages of ejected and accreted planets, the number of collisions, the dependence of outcomes on planetary masses, the time spent arXiv:astro-ph/0505234v1 11 May 2005 in 2:1 and 3:1 resonances, and the effects of the planetary IMF.

  • THE ORION CONSTELLATION the Great Hunter Orion Constellation Lies in the Northern Sky, on the Celestial Equator
    THE ORION CONSTELLATION the Great Hunter Orion constellation lies in the northern sky, on the celestial equator. It is one of the brightest and best known constellations in the night sky. Orion is also known as the Hunter: it is associated with one in mythology. The constellation represents the mythical hunter Orion, who is often depicted in star maps as either facing the charge of Taurus, the bull, or chasing after the hare (constellation Lepus) with his two hunting dogs, represented by the nearby constellations Canis Major and Canis Minor. The constellation contains two of the ten brightest stars in the sky – Rigel (Beta Orionis) and Betelgeuse (Alpha Orionis) – a number of famous nebulae – the Orion Nebula, De Mairan’s Nebula and the Horsehead Nebula, among others, and one of the most prominent asterisms in the night sky – Orion’s Belt. FACTS • Orion is the 26th constellation in size, occupying an area of 594 square degrees. • It is located in the first quadrant of the northern hemisphere (NQ1) and can be seen at latitudes between +85° and -75°. • The neighboring constellations are Eridanus, Gemini, Lepus, Monoceros and Taurus. • Orion contains three Messier objects – M42, (NGC 1976) The Orion Nebula, M43, (NGC 1982) De Mairan’s Nebula, and M78, (NGC 2068) • It has seven stars with known planets. • There are two meteor showers associated with Orion, the Orionids and the Chi Orionids. The Orionid meteor shower reaches its peak around October 21 every year • Orion belongs to the Orion family of constellations, along with Canis Major, Canis Minor, Lepus and Monoceros MYTH The constellation Orion has its origins in Sumerian mythology, specifically in the myth of Gilgamesh.

In fact, Mirach's Ghost is just a faint, fuzzy galaxy, well known to astronomers, that happens to be seen nearly along the line-of-sight to Mirach, a bright star. Centered in this star field, Mirach is also called Beta Andromedae. About 200 light-years distant, Mirach is a red giant star, cooler than the Sun but much larger and so intrinsically much brighter than our parent star. In most telescopic views, glare and diffraction spikes tend to hide things that lie near Mirach and make the faint, fuzzy galaxy look like a ghostly internal reflection of the almost overwhelming starlight. Still, appearing in this sharp image just above and to the right, Mirach's Ghost is cataloged as galaxy NGC 404 and is estimated to be some 10 million light-years away. – Explanation from APOD/NASA Credit & Copyright – Anthony Ayiomamitis (Athens, Greece) Website = http://www.perseus.gr/ & eMail = [email protected] Inside This Issue: Important ACT Upcoming Dates: Vice President's Message - p2 IYoA - - - - - - - - - - - - - - - p6 Public Star Party… Fri.

There is considerable debate in the literature regarding the galaxy's fundamental properties such as its Hubble type (lenticular galaxy or a giant elliptical galaxy)[6] and distance (10-16 million light-years).[2][1][3][4][5] NGC 5128 is one of the closest radio galaxies to Earth, so its active galactic nucleus has been extensively studied by professional astronomers.[10] The galaxy is also the fifth brightest in the sky,[10] making it an ideal amateur astronomy target,[11] although the galaxy is only visible from low northern latitudes and the southern hemisphere.
