  • Binocular Universe: Northern Exposure
    Binocular Universe: Northern Exposure March 2013 Phil Harrington he northern circumpolar sky holds many binocular targets that we can enjoy throughout the year. This month, let's take aim at the constellation Ursa TMinor, the Little Bear. You may know it better as the Little Dipper, an asterism made up of the seven brightest stars in the Little Bear. Above: Winter star map from Star Watch by Phil Harrington. Above: Finder chart for this month's Binocular Universe. Chart adapted from Touring the Universe through Binoculars Atlas (TUBA), www.philharrington.net/tuba.htm Call it what you will, this star group is most famous as the home of the North Star, Polaris [Alpha (α) Ursae Minoris]. Earth's rotational axis is aimed just three- quarters of a degree away from Polaris, causing it to trace out a very tiny circle around that invisible point every 24 hours. The North Celestial Pole is slowly moving closer to Polaris. It will continue to close to within 14 minutes of arc around the year 2105, when it will slowly start to pull away. While Polaris is currently the pole star, the 26,000-year wobble of Earth's axis, called precession, causes the Celestial Pole's aim to trace a 47° circle in the sky. For instance, during the building of the pyramids nearly 4,600 years ago, the North Pole was aimed toward the star Thuban in Draco. Fast forward 5,200 years from now and the pole will be point near Alderamin in Cepheus. Most of us at one time or another have heard someone misspeak by referring to Polaris as the brightest star in the night sky.

  • The Hummel Planetarium Experience
    THE HUMMEL PLANETARIUM | EXPERIENCE About us: The Arnim D. Hummel Planetarium has been nestled on the south side of Eastern Kentucky University’s campus since 1988. Since then, we have provided informal science education programs to EKU students, P-12 students, as well as the community. The main theme of our programs are seated in the fields of physics and astronomy, but recent programs have explored a myriad of STEM related topics through engaging hands on experiences. Who can visit and when? We are open to the public during select weekday afternoons and evenings (seasonal) as well as most Saturdays throughout the year. The public show schedule is pre-set, and the programs serve audiences from preschool age and up. We also welcome private reservations for groups of twenty or more Mondays through Fridays during regular business hours. Examples of groups who reserve a spot include school field trips, homeschool groups, church groups, summer camps, and many more. When booking a private reservation, your group may choose which show to watch, and request a customized star talk, if needed. What happens during a visit? Most visits to the Planetarium involve viewing a pre-recorded show which is immediately followed by a live Star Talk presentation inside of the theater. A planetarium theater is unique because the viewing area is rounded into the shape of a dome instead of a flat, two-dimensional screen. The third dimension enables you, the viewer, to become immersed in the scenes displayed on the dome. A list of the pre-recorded shows we offer is found on the next page.

His companion Artemis was greatly saddened and arranged for Orion to be immortalised among the stars.

    UNA Planetarium Image of the Month Newsletter Vol. 2. No. 9 Sept 15, 2010 We are planning to offer some exciting events this fall, including a return of the laser shows. Our Fall Laser Shows will feature images and music of Led Zeppelin and Pink Floyd. The word laser is actually an acronym for Light Amplification by Stimulated Emission of Radiation”. We use many devices with lasers in them, from CD players to the mouse on your desk. What many people don’t know is that there are also natural lasers in space. The lasers in space often come from molecules (groups of one or more atoms sharing electrons); we call these masers. One of the more important one is the OH In 1987, astronomers observing from Chile observed a new star in the sky.

The lightcurve period for Cyrene of 12.707±0.015 h (with amplitude 0.22 mag) confirms prior studies. The lightcurve period of 8.37784±0.00003 h (amplitude 0.32 mag) for Mathesis differs from previous studies. For Italia, color indices (B-V)=0.87±0.07, (V-R)=0.48±0.05, and phase curve parameters H=10.4, G=0.15 have been determined. For Sabrina, this study provides the first reported lightcurve period 43.41±0.02 h, with 0.30 mag amplitude. Altimira Observatory, located in southern California, is equipped with a 0.28-m Schmidt-Cassegrain telescope (Celestron NexStar- 454 Mathesis. DiMartino et al.

Current amount of ∼500 asteroid models derived from the disk-integrated photometry by the lightcurve inversion method allows us to study not only the spin-vector properties of the whole population of MBAs, but also of several individual collisional families. Aims. We create a data set of 152 asteroids that were identified by the HCM method as members of ten collisional families, among them are 31 newly derived unique models and 24 new models with well-constrained pole-ecliptic latitudes of the spin axes.
