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. -
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. -
2020 Observatory Schedule
Astronomy Club of Akron 2020 Observatory Schedule 5031 Manchester Road, Akron, OH www.acaoh.org – The following events are open to the public. Please join us for stargazing and educational activities. Please arrive on time to avoid headlight distraction. – For notice of “impromptu star parties” not listed, send e-mail to [email protected] to request e-mail notification of unscheduled observing sessions. – Events will be cancelled if skies are cloudy. Always check website for star party status two hours before event. – This is an outdoor activity in an unheated environment. Nighttime temperatures drop rapidly, even during summer. A general rule of thumb is to dress for 15 degrees cooler than predicted nighttime low temperature. – Please respect those who set up their telescopes. Children should be supervised at all times. The observatory grounds are no place for toys or tomfoolery. – Please, No Smoking on observatory grounds. Smoke reacts with optical surfaces, damaging optical coatings. – Please, no use of cell phones or tablets in observatory (to preserve night vision). April 18 – 8:15pm July 18 – 9:00pm Venus is well placed for observing early, and then we’ll view Come out to view open cluster NGC6633, Wild Duck Ghost of Jupiter and the beautiful star cluster M37 through Cluster, Ring Nebula, M26 Star Cloud, and Swan Nebula the 16” observatory telescope and view Beehive Cluster using an OIII filter. through the 100mm wide field telescope. July 25 – 9:00pm April 25 – 8:30pm We’ll be observing a 5-day old Moon. This is a great Special Event: Messier Marathon – stay all night to observe opportunity to see crater central peaks lit up by the grazing all 110 Messier objects with ACA members. -

March 2021 These Pages Are Intended to Help You Find Your Way Around the Sky
WHAT'S UP THIS MONTH – MARCH 2021 THESE PAGES ARE INTENDED TO HELP YOU FIND YOUR WAY AROUND THE SKY The chart above shows the whole night sky as it appears on 15th March at 21:00 (9 o’clock) 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 8 o’clock GMT at the beginning of the month and at 10 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 throughout the year from Britain and is always quite easy to find. This month it is high in the North East. -
