    How Far Away Is It – Planetary Nebula Planetary Nebula {Abstract – In this segment of our “How far away is it” video book, we cover Planetary Nebula. We begin by introducing astrophotography and how it adds to what we can see through a telescope with our eyes. We use NGC 2818 to illustrate how this works. This continues into the modern use of Charge-Coupled Devices and how they work. We use the planetary nebula MyCn18 to illustrate the use of color filters to identify elements in the nebula. We then show a clip illustrating the end-of-life explosion that creates objects like the Helix Planetary Nebula (NGC 7293), and show how it would fill the space between our Sun and our nearest star, Proxima Centauri. Then, we use the Cat’s Eye Nebula (NGC 6543) to illustrate expansion parallax. As a fundamental component for calculating expansion parallax, we also illustrate the Doppler Effect and how we measure it via spectral line red and blue shifts. We continue with a tour of the most beautiful planetary nebula photographed by Hubble. These include: the Dumbbell Nebula, NGC 5189, Ring Nebula, Retina Nebula, Red Rectangle, Ant Nebula, Butterfly Nebula, , Kohoutek 4- 55, Eskimo Nebula, NGC 6751, SuWt 2, Starfish, NGC 5315, NGC 5307, Little Ghost Nebula, NGC 2440, IC 4593, Red Spider, Boomerang, Twin Jet, Calabash, Gomez’s Hamburger and others culminating with a dive into the Necklace Nebula. We conclude by noting that this will be the most likely end for our Sun, but not for billions of years to come, and we update the Cosmic Distance Ladder with the new ‘Expansion Parallax’ rung developed in this segment.} Introduction [Music @00:00 Bizet, Georges: Entracte to Act III from “Carman”; Orchestre National de France / Seiji Ozawa, 1984; from the album “The most relaxing classical album in the world…ever!”] Planetary Nebulae represent some of the most beautiful objects in the Milky Way.

  • Messier Objects
    Messier Objects From the Stocker Astroscience Center at Florida International University Miami Florida The Messier Project Main contributors: • Daniel Puentes • Steven Revesz • Bobby Martinez Charles Messier • Gabriel Salazar • Riya Gandhi • Dr. James Webb – Director, Stocker Astroscience center • All images reduced and combined using MIRA image processing software. (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.

    Pretoria Centre ASSA April 2020 Page 1 of 11 NEWSLETTER APRIL 2020 Dear member In the light of the current situation and based upon advice from a virologist at one of the leading pathology laboratories, we regret to have to cancel the March and April viewing evenings and meetings of the Pretoria Centre of ASSA. The situation will be reviewed in time for the May activities and members will be informed of any changes. This decision was not taken lightly, but we believe the health of our members is important and we would not like to be the reason one of our members should fall victim to the virus. We apologize for the inconvenience and trust the skies will be clear wherever you wish to spend time under the stars.

  • Investigating the Beehive Cluster with Gaia Blaise Whitesell — Astronomy Capstone 2019
    Investigating the Beehive Cluster with Gaia Blaise Whitesell — Astronomy Capstone 2019 In this problem set, we will explore the capabilities of the publicly available data from Gaia DR2, which can be found at http://gea.esac.esa.int/archive/ or queried directly from within Python. We will focus on a single target: the Beehive cluster (M44, also known as Praesepe or NGC 2632). This open cluster is located at a distance of roughly 200 pc in the constellation Cancer with coordinates (α; δ) = (130:1°; 19:67°). We will download Gaia data in the vicinity of the cluster, select only the stars belonging to the cluster, and then characterize the properties of those stars in the cluster. 1. Getting Data For our analysis we need these columns from the Gaia DR2 database gaiadr2.gaia_source: source_id A numeric identifier for the object ra Right ascension (degrees) dec Declination (degrees) parallax Parallax (mas) pmra Proper motion in right ascension (mas/yr) pmdec Proper motion in declination (mas/yr) phot_g_mean_mag Magnitude in Gaia G band (mags) bp_rp Gaia BP–RP color (mags) Select objects within 4 degrees of the cluster center. At the rough distance of the Beehive cluster, how many parsecs does that correspond to? We want to include objects at least that far in front and behind the cluster. Since we don’t know distances as precisely, we should expand the range by a factor of 3 or 4 to avoid missing cluster stars. What parallaxes (in mas) does this distance range correspond to? Use those parallax values as conditions to exclude objects far away from the cluster.

    AAAssstttrrrooonnnooomyyy CCCllluuubbb ooofff TTTuuulllsssaaa OOOOOObbbbbbsssssseeeeeerrrrrrvvvvvveeeeeerrrrrr October 2009 Messier 15 Jean-Dominique Maraldi discovered M15 on September 7, 1746. He described it as 'A nebulous star, fairly bright and composed of many stars'. Charles Messier, who cataloged it on June 3, 1764, and Johann Bode couldn't make this out and described it as 'nebula without stars,' so that it remained to William Herschel in 1783 to resolve this fine star cluster. M15 was the first globular cluster in which a planetary nebula, Pease 1 or K 648 ("K" for "Kuster"), could be identified (Pease 1928, on photographic plates taken at Mt. Wilson in 1927). M15 can be found extremely easily: First find the 2nd magnitude star Epsilon Pegasi, and Theta Pegasi SE of it. Follow the line from Theta over Epsilon and find M15 3 1/2 deg W and 2 1/4 deg N of Epsilon. A 6th magnitude star is about 20' away to the East; another one of magnitude 7.5 is about 5' to the NNE. With its apparent visual brightness of magnitude 6.2, M15 is about at the limit of visibility for the naked eye under very good conditions. The slightest optical aid, opera glass or small binoculars, reveals it as a round nebulous object. It appears as a round mottled nebula in 4-inch telescopes, with at best the very brightest stars visible, but otherwise unresolved in a fine star field. Be sure to catch & log M15 this month!

  • What Has Hubble Learned from Star Clusters? Visual Notes
    Hubblecast 69: What has Hubble learned from star clusters? Visual notes 00:00 [Narrator] 1. Star clusters hang like sparkling firework displays in the sky, making them favourite observational targets for astronomers. Hubble has observed its fair share of these cosmic baubles, imaging and studying them to explore their secrets. This new image from Hubble shows a globular cluster known as Messier 15. As well as containing over 100 000 old stars, this cluster hosts something dark and mysterious at its heart. 00:39 2. Intro 01:0 [Narrator] 3. Star clusters are some of the most beautiful objects in our skies. Hubble has viewed many of these over the years — but it is not all style over substance. These clusters are incredibly useful to the astronomers studying them. What can they tell us about our Universe? 01:24 [Narrator] 4. There are two main types of star cluster: open, and globular. Most stars, including the Sun, are thought to have formed within open star clusters — groups of thousands of stars loosely bound together by gravity, destined to be spread throughout their host galaxy once the cluster matures and most of its gas disperses. Globular clusters are different; they are huge balls of old stars that orbit the centres of galaxies. Many of them were once little galaxies, cannibalised by their larger companions over the history of the Universe. 02:16 [Narrator] 5. Hubble has explored many globular clusters. The Milky Way alone has over 150 of these starry satellites, and Hubble’s sharp vision can resolve the individual stars.

  • February 2019 These Pages Are Intended to Help You Find Your Way Around the Sky
    WHAT'S UP THIS MONTH – FEBRUARY 2019 THESE PAGES ARE INTENDED TO HELP YOU FIND YOUR WAY AROUND THE SKY The chart above shows the night sky as it appears on 15th February at 21:00 (9 o’clock) in the evening Greenwich Mean Time (GMT). 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 10 o’clock GMT at the beginning of the month and at 8 o’clock GMT 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 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 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. Ursa Major is visible 1 of 13 pages throughout the year from Britain and is always easy to find. This month it is in the North East.

  • A Basic Requirement for Studying the Heavens Is Determining Where In
    Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun­ damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short).
