The SPIRIT Telescopes teachers guide Evolution of the Universe 2: The SPIRIT telescopes Components NAME DESCRIPTION AUDIENCE The SPIRIT telescopes This guide explains how to use the SPIRIT telescopes. It teachers includes question and discussion points to support students’ teachers guide investigations, and a target list of deep sky objects for students to select and image. Deep sky objects This background sheet provides information on deep sky teachers objects, including open clusters, globular clusters, nebulae background sheet and galaxies. It also includes tips on how to obtain the best images of deep sky objects with the SPIRIT telescopes. Introduction to SPIRIT This guide helps students take their first images with the students SPIRIT telescopes. quick guide SPIRIT observation log This worksheet guides students to select four deep sky students objects to image using the SPIRIT telescopes. They describe, worksheet classify and publish a report on their selected objects. Purpose Outcomes To Explore the characteristics of astronomical objects Students: by using the SPIRIT telescopes to image deep sky • use the SPIRIT telescopes to image deep sky objects. objects, including open and globular star clusters, galaxies and nebulae; and • research objects they have imaged and publish a report describing them. Activity summary ACTIVITY POSSIBLE STRATEGY In class whole class, teacher- directed questions Teacher poses questions, such as: whiteboard summary of • What different kinds of objects can we see with the naked eye in the night sky? answers • What other kinds of objects might we be able to see if we had access to a powerful telescope? Teacher provides information about the SPIRIT telescope initiative through teacher-led, whole class presentation of the SPIRIT web site: http://spice.wa.edu.au/spirit/ small groups Teacher details the process for using SPIRIT telescopes (see Telecope access on the SPIRIT web site). Students spend time exploring the SPIRIT web site. Particular attention should be small groups given to content in Guides and documents, including SPIRIT exposure guide and Taking your first image with SPIRIT. Teacher demonstrates logging onto SPIRIT I or SPIRIT II and provides an overview teacher demonstration of the imaging interface. Particular attention is given to the process of taking an image, and location of student images and files. NOTE: The demonstration can be completed in class time, however the telescope is unable to image astronomical objects during daylight hours. ast0691 | Evolution of the Universe 2: The SPIRIT telescopes (teachers guide) developed for the Department of Education WA © The University of Western Australia 2014 for conditions of use see spice.wa.edu.au/usage version 1.0 page 1 Licensed for NEALS ACTIVITY POSSIBLE STRATEGY Teacher distributes the guide, Introduction to SPIRIT, and worksheet, SPIRIT small groups observation log, divides the class into small groups, issues user names and passwords and allocates a 30-minute evening time slot for each group to access the telescope. Teacher provides a target list of deep sky objects from which students select four objects to image during their allocated 30-minute time slot. Students use Stellarium to plan how they will capture their images from a home computer. On observation night small groups Using instructions in the guide, Introduction to SPIRIT, students log onto a SPIRIT telescope and image four objects selected earlier from the target list. Record details of each image in observation log. Students must capture their four images in the 30-minutes allocated to their group and must log off to allow next group to access the telescope. In class small groups and individual work Students download their images and research objects they have imaged. They write a paragraph about each object, then combine their image and description into a report, as described in the worksheet. Teacher arranges a class exhibition of reports. Students select the best images to students vote on the best upload to the SPIRIT telescope gallery. images Using students’ image gallery, teacher poses a series of questions to draw together small group discussion knowledge students have discovered during the activity, such as: or whole class sharing of ideas, whiteboard • What different types of objects did you image with the telescope? summary. • What similarities and differences can you see in images of open and globular star clusters? • What similarities and differences can you see in images of nebulae? • What similarities and differences can you see in images of galaxies? • Can you suggest how galaxies could be classified, according to their shape? • What did you learn about the way astronomers work, from your use of the SPIRIT telescope? • What did you enjoy/learn from using the SPIRIT telescopes? • What other activities would you like to do using the SPIRIT telescopes? Information for teachers It is strongly advised that teachers wishing to The worksheet, SPIRIT observation log, guides students undertake this activity contact the SPIRIT program to select objects and command the telescope to image manager at SPICE to seek assistance in planning the them remotely from their home computer, in real time, activity and allocating time for telescope booking. during an allocated 30-minute period.

    The MARCH 2002 DENVER OBSERVER Newsletter of the Denver Astronomical Society One Mile Nearer the Stars How Many in One Night?? Gearing up for the Messier Marathon? Those folks who are new to astronomy may not yet be able to relate to the sheer joy of braving the early-spring temperatures (brrrrr) for a full night (and morning—I’m talking dusk to dawn, here) of observing some of the most beautiful objects in the heavens. Why now? Because for only a few weeks during the year is it possible to see all of the Messier objects in one night. Astronomers will dig in their heels and tripods, get out the star charts (See Page 7), and knock off one object after the next. Some people actually catalog 70 of the available 110 targets and submit their achievements to the Astronomical League for the coveted Messier Certificate. Others just like to look at the beautiful celestial wonders like the one in the photo to the left.

  • 02 Southern Cross
    Asterism Southern Cross The Southern Cross is located in the constellation Crux, the smallest of the 88 constellations. It is one of the most distinctive. With the four stars Mimosa BeCrux, Ga Crux, A Crux and Delta Crucis, forming the arms of the cross. The Southern Cross was also used as a remarkably accurate timepiece by all the people of the southern hemisphere, referred to as the ‘Southern Celestial Clock’ by the portuguese naturalist Cristoval D’Acosta. It is perpendicular as it passes the meridian, and the exact time can thus be calculated visually from its angle. The german explorer Baron Alexander von Humboldt, sailing across the southern oceans in 1799, wrote: “It is a timepiece, which advances very regularly nearly 4 minutes a day, and no other group of stars affords to the naked eye an observation of time so easily made”. Asterism - An asterism is a distinctive pattern of stars or a distinctive group of stars in the sky. Constellation - A grouping of stars that make an imaginary picture in the sky.

Rapidly mass-segregating to the center of GCs, BHs act as a dynamical energy source via repeated super-elastic scattering, delaying onset of core collapse and limiting mass segregation for visible stars. While recent discoveries of BH candidates in Galactic and extragalactic GCs have further piqued inter- est in BH-mediated cluster dynamics, numerical models show that even if significant BH populations remain in today's GCs, they are not typically in directly detectable configurations. We demonstrated in Weatherford et al.(2018) that an anti-correlation between a suitable measure of mass segregation (∆) in observable stellar populations and the number of retained BHs in GC models can be applied to indirectly probe BH populations in real GCs. Here, we estimate the number and total mass of BHs in 50 Milky Way GCs from the ACS Globular Cluster Survey. For each GC, ∆ is measured between observed main sequence populations and fed into correlations between ∆ and BH retention found in our CMC Cluster Catalog's models.
