So, how can I observe there? The Badlands National Park in South Dakota participates in the Night Sky Program and accepted my application as a “Volunteer In Parks” (VIP) for a July stint. I corresponded with Ranger Larry Smith and learned about the public telescope sessions planned (solar observing with a Coronado MaxScope 40 during the day and an amphitheater program at 9pm followed by telescope observing. They have 12” & 16” Dobsonians and an 11” Schmidt-Cassegrain Telescope. The official National Park Service Night Sky Program is aimed at light pollution awareness. See the supporting website.

  • The Turbulent Tale of a Tiny Galaxy by Trudy Bell and Dr
    Space Place Partners’ Article August 2010 The Turbulent Tale of a Tiny Galaxy by Trudy Bell and Dr. Tony Phillips Next time you hike in the woods, pause at a babbling stream. Watch carefully how the water flows around rocks. After piling up in curved waves on the upstream side, like the bow wave in front of a motorboat, the water speeds around the rock, spilling into a riotous, turbulent wake downstream. Lightweight leaves or grass blades can get trapped in the wake, swirling round and round in little eddy currents that collect debris. Astronomers have found something similar happening in the turbulent wake of a tiny galaxy that is plunging into a cluster of 1,500 galaxies in the constellation Virgo. In this case, however, instead of collecting grass and leaves, eddy currents in the little galaxy’s tail seem to be gathering gaseous material to make new stars. “It’s a fascinating case of turbulence [rather than gravity] trapping the gas, allowing it to become dense enough to form stars,” says Janice A. Hester of the California Institute of Technology in Pasadena. The tell-tale galaxy, designated IC 3418, is only a hundredth the size of the Milky Way and hardly stands out in visible light images of the busy Virgo Cluster. Astronomers realized it was interesting, however, when they looked at it using NASA's Galaxy Evolution Explorer satellite. “Ultraviolet images from the Galaxy Evolution Explorer revealed a long tail filled with clusters of massive, young stars,” explains Hester. Galaxies with spectacular tails have been seen before.

IC 3418 has a spectacular 17 kpc length UV-bright tail comprised of knots, head–tail, and linear stellar features. The only Hα emission arises from a few H ii regions in the tail, the brightest of which are at the heads of head–tail UV sources whose tails point toward the galaxy (“fireballs”).

P. Kenney3, Luca Cortese4, Franc¸oise Combes5, Masafumi Yagi6,7, Michitoshi Yoshida8, Jan Palouˇs1, and Elke Roediger9 Accepted to the Astrophysical Journal on March 31, 2017 ABSTRACT We have discovered large amounts of molecular gas, as traced by CO emission, in the ram pressure stripped gas tail of the Coma cluster galaxy D100 (GMP 2910), out to large distances of about 50 kpc. D100 has a 60 kpc long, strikingly narrow tail which is bright in X-rays and Hα. Our observations 9 with the IRAM 30m telescope reveal in total 10 M⊙ of H2 (assuming the standard CO-to-H2 conversion) in several regions along the tail, thus∼ indicating that molecular gas may dominate its mass. Along the tail we measure a smooth gradient in the radial velocity of the CO emission that is offset to lower values from the more diffuse Hα gas velocities. Such a dynamic separation of phases may be due to their differential acceleration by ram pressure. D100 is likely being stripped at a high orbital velocity & 2200 kms−1 by (nearly) peak ram pressure. Combined effects of ICM viscosity and magnetic fields may be important for the evolution of the stripped ISM. We propose D100 has reached a continuous mode of stripping of dense gas remaining in its nuclear region. D100 is the second known case of an abundant molecular stripped-gas tail, suggesting that conditions in the ICM at the centers of galaxy clusters may be favorable for molecularization.

DC 20402 PREFACE A critical first step in determining distances to galaxies is to measure some property (e.g., size or luminosity) of primary objects such as stars of specific types, H II regions, and supernovae remnants that are resolved out of the general galaxy stellar content. Very few galaxies are suitable for study at such high resolution because of intense disk background light, excessive crowding by contaminating images, internal obscuration due to dust, high inclination angles, or great distance. Nevertheless, these few galaxies with accurately measurable primary distances are required to calibrate secondary distance indicators which have greater range. If telescope time is to be optimized, it is important to know which galaxies are suitable for specific resolution studies. No atlas of galaxy photographs at a scale adequate for resolution of stellar content exists that is complete for the bright galaxy sample [e.g.; for the Shapley-Ames (1932) list, augmented with listings in the Second Reference Catalog (RC2) (de Vaucouleurs, de Vaucouleurs, and Corwin, 1977); and the Uppsala Nilson (1973) catalogs].
