The member- ship at the NCRAL 2018 conference in Sturgeon Bay, WI, heard and approved a motion for the NCRAL Regional Council to create a “one-time allocation of a suitable amount of money for the creation of several draft NCRAL logos, one of which will be amended as necessary and approved in concept by the general membership at the NCRAL 2019 regional meeting. The approved draft will be finalized shortly thereafter.” To this end, the leadership is now soliciting suggestions for logos. A set of guidelines and criteria have been ap- proved by the Regional Committee consisting of NCRAL-affiliated society presidents and ALCors as well as the Ex- ecutive Officers (chair, vice chair, secretary/treasurer, and regional representative to the National Council). The guidelines and criteria for preparing and selecting a draft logo are as follows: Guidelines: 1. We are not currently seeking finished products, merely draft logos. 2. The draft logos need not be design by a member of a NCRAL-affiliated society; anyone is eligible to enter the competition. 3. More than one submission by the same person is permissible. 4. Drawings must be the original work of the competitor; no use of preexisting logos will be permitted; no copycatting of existing logos will be permitted. 5. Both astronomically accurate and stylized logos are acceptable. 6. Draft logos may be submitted at any stage of development as long as they adhere to these guidelines. 7. Drafts may be submitted in either color and/or black & white. 8. Drawings must be submitted as high-resolution files (e.g., 250 kB). 9. All logo drafts must be electronically submitted via email to the Regional Chair at [email protected]. Submissions must include name of author, contact information, club affiliation (if any), statement indicating that the draft logo the original work of the submitter.

(Mirametrics) What are Messier Objects? • Messier objects are a list of astronomical sources compiled by Charles Messier, an 18th and early 19th century astronomer. He created a list of distracting objects to avoid while comet hunting. This list now contains over 110 objects, many of which are the most famous astronomical bodies known. The list contains planetary nebula, star clusters, and other galaxies. - Bobby Martinez The Telescope The telescope used to take these images is an Astronomical Consultants and Equipment (ACE) 24- inch (0.61-meter) Ritchey-Chretien reflecting telescope. It has a focal ratio of F6.2 and is supported on a structure independent of the building that houses it. It is equipped with a Finger Lakes 1kx1k CCD camera cooled to -30o C at the Cassegrain focus. It is equipped with dual filter wheels, the first containing UBVRI scientific filters and the second RGBL color filters. Messier 1 Found 6,500 light years away in the constellation of Taurus, the Crab Nebula (known as M1) is a supernova remnant. The original supernova that formed the crab nebula was observed by Chinese, Japanese and Arab astronomers in 1054 AD as an incredibly bright “Guest star” which was visible for over twenty-two months. The supernova that produced the Crab Nebula is thought to have been an evolved star roughly ten times more massive than the Sun.

  • Distinguishing Standard from Modified Gravity in the Local Group And
    Thesis of Indranil Banik,1{40 (2018) 24 May 2018 Compiled using MNRAS LATEX style file v3.0 Distinguishing Standard from Modified Gravity in the Local Group and beyond Indranil Banik1∗, Supervisor: Hongsheng Zhao1 1Scottish Universities Physics Alliance, University of Saint Andrews, North Haugh, Saint Andrews, Fife, KY16 9SS, United Kingdom 24 May 2018 ABSTRACT The works in this portfolio test the hypothesis that it is not possible to extrapolate the Newtonian inverse square law of gravity from Solar System to galaxy scales. In particular, I look into various tests of Modified Newtonian Dynamics (MOND), which posits a modification below a very low acceleration threshold. Although discrepan- cies with Newtonian dynamics are indeed observed, they can usually be explained by invoking an appropriate distribution of invisible mass known as dark matter (DM). This leads to the standard cosmological paradigm, ΛCDM. I consider how it may be distinguished from MOND using collision velocities of galaxy clusters, which should sometimes be much faster in MOND. I focus on measuring these velocities more ac- curately and conclude that this test ought to be feasible in the near future. For the time being, I look at the much nearer and more accurately observed Local Group (LG) of galaxies. Its main constituents − the Milky Way (MW) and Andromeda (M31) − should have undergone a past close flyby in MOND but not in ΛCDM. The fast MW-M31 relative motion around the time of their flyby would have allowed them to gravitationally slingshot any passing LG dwarf galaxies out at high speed. I consider whether there is any evidence for such high-velocity galaxies (HVGs).

  • Astronomy and Astrophysics Books in Print, and to Choose Among Them Is a Difficult Task
    APPENDIX ONE Degeneracy Degeneracy is a very complex topic but a very important one, especially when discussing the end stages of a star’s life. It is, however, a topic that sends quivers of apprehension down the back of most people. It has to do with quantum mechanics, and that in itself is usually enough for most people to move on, and not learn about it. That said, it is actually quite easy to understand, providing that the information given is basic and not peppered throughout with mathematics. This is the approach I shall take. In most stars, the gas of which they are made up will behave like an ideal gas, that is, one that has a simple relationship among its temperature, pressure, and density. To be specific, the pressure exerted by a gas is directly proportional to its temperature and density. We are all familiar with this. If a gas is compressed, it heats up; likewise, if it expands, it cools down. This also happens inside a star. As the temperature rises, the core regions expand and cool, and so it can be thought of as a safety valve. However, in order for certain reactions to take place inside a star, the core is compressed to very high limits, which allows very high temperatures to be achieved. These high temperatures are necessary in order for, say, helium nuclear reactions to take place. At such high temperatures, the atoms are ionized so that it becomes a soup of atomic nuclei and electrons. Inside stars, especially those whose density is approaching very high values, say, a white dwarf star or the core of a red giant, the electrons that make up the central regions of the star will resist any further compression and themselves set up a powerful pressure.1 This is termed degeneracy, so that in a low-mass red 191 192 Astrophysics is Easy giant star, for instance, the electrons are degenerate, and the core is supported by an electron-degenerate pressure.

  • What's up This Month – May 2017
    WHAT'S UP THIS MONTH – MAY 2017 THESE PAGES ARE INTENDED TO HELP YOU FIND YOUR WAY AROUND THE SKY The chart on the last page is included for printing off and use outside The chart above shows the whole night sky as it appears on 15th May at 22:00 (10 o’clock) in the evening British Summer Time (BST). As the Earth orbits the Sun and we look out into space each night the stars will appear to have moved across the sky by a small amount. Every month Earth moves one twelfth of its circuit around the Sun, this amounts to 30 degrees each month. There are about 30 days in each month so each night the stars appear to move about 1 degree. The sky will therefore appear the same as shown on the chart above at 11 o’clock BST at the beginning of the month and at 9 o’clock BST at the end of the month. The stars also appear to move 15º (360º divided by 24) each hour from east to west, due to the Earth rotating once every 24 hours. The sky appears to rotate from east to west around the Pole Star (Polaris). The centre of the chart will be the position in the sky directly overhead, called the Zenith. First we need to find some familiar objects so we can get our bearings. The Pole Star Polaris can 1 be easily found by first finding the familiar shape of the Great Bear ‘Ursa Major’ that is also sometimes called the Plough or even the Big Dipper by the Americans.
