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.

The Local Galaxy Volume
11-1 How Far Away Is It – The Local Galaxy Volume The Local Galaxy Volume {Abstract – In this segment of our “How far away is it” video book, we cover the local galaxy volume compiled by the Spitzer Local Volume Legacy Survey team. The survey covered 258 galaxies within 36 million light years. We take a look at just a few of them including: Dwingeloo 1, NGC 4214, Centaurus A, NGC 5128 Jets, NGC 1569, majestic M81, Holmberg IX, M82, NGC 2976,the unusual Circinus, M83, NGC 2787, the Pinwheel Galaxy M101, the Sombrero Galaxy M104 including Spitzer’s infrared view, NGC 1512, the Whirlpool Galaxy M51, M74, M66, and M96. We end with a look at the tuning fork diagram created by Edwin Hubble with its description of spiral, elliptical, lenticular and irregular galaxies.} Introduction [Music: Johann Pachelbel – “Canon in D” – This is Pachelbel's most famous composition. It was written in the 1680s between the times of Galileo and Newton. The term 'canon' originates from the Greek kanon, which literally means "ruler" or "a measuring stick." In music, this refers to timing. In astronomy, "a measuring stick" refers to distance. We now proceed to galaxies more distant than the ones in our Local Group.] The Local volume is the set of galaxies covered in the Local Volume Legacy survey or LVL, for short, conducted by the Spitzer team. It is a complete sample of 258 galaxies within 36 million light years. This montage of images shows the ensemble of galaxies as observed by Spitzer. The galaxies are randomly arranged but their relative sizes are as they appear on the sky.

Monthly Observer's Challenge
MONTHLY OBSERVER’S CHALLENGE Las Vegas Astronomical Society Compiled by: Roger Ivester, Boiling Springs, North Carolina & Fred Rayworth, Las Vegas, Nevada With special assistance from: Rob Lambert, Las Vegas, Nevada JUNE 2015 Introduction The purpose of the Observer’s Challenge is to encourage the pursuit of visual observing. It’s open to everyone that’s interested, and if you’re able to contribute notes, and/or drawings, we’ll be happy to include them in our monthly summary. We also accept digital imaging. Visual astronomy depends on what’s seen through the eyepiece. Not only does it satisfy an innate curiosity, but it allows the visual observer to discover the beauty and the wonderment of the night sky. Before photography, all observations depended on what the astronomer saw in the eyepiece, and how they recorded their observations. This was done through notes and drawings, and that’s the tradition we’re stressing in the Observers Challenge. We’re not excluding those with an interest in astrophotography, either. Your images and notes are just as welcome. The hope is that you’ll read through these reports and become inspired to take more time at the eyepiece, study each object, and look for those subtle details that you might never have noticed before. M83 – NGC-5236 The Southern Pinwheel Galaxy In Hydra M83, also known as NGC-5236, is a face-in barred spiral galaxy in the southern sky, which lies in the constellation of Hydra. Charles Messier added it to his catalogue of non-comets in March 1781, but it was actually discovered by Nicolas Louis de Lacaille on February 23, 1752 from his observatory in the Cape of Good Hope in South Africa.

Whirlpools and Pinwheels on the Sky
Whirlpools and pinwheels on the sky Domingos Soares Galaxies exist in many diﬀerent forms and count by, at least, the hundreds of billions, according to estimations made from the observations of the Hubble Space Telescope. Among all of them, there are no doubts that the most spectacular are the so-called \spiral galaxies". Our own galaxy, the Milky Way galaxy, is a member of that family. Spiral galaxies are so named because of the distinctive aspect they present to the observer, namely, of a spiral-shaped structure similar to a whirlpool or a pinwheel. They are also called \disk galaxies" because the galactic material | stars, gas and interstellar dust | is distributed in the shape of a \thick" disk. The stars constitute the main constituents of galaxies, at least with respect to their visual appearance. They emit the major part of the visible light of a galaxy, be it a spiral or not. The typical visual aspect of spiral galaxies is due to the structures that astronomers call \spiral arms". The most bright stars of a galaxy are those that delineate the arms. These, however, contribute little to the total mass of the galaxy, but due to their extraordinary brightness they are the most noticeable on a visual inspection. The spiral galaxy disks rotate. And this is typical in those galaxies: the galactic material spins around the disk center, which is called \galactic center". But the rotation is not like the spin of a rigid disk, like, for example, a CD, in which all the points make a full turn in the same time interval.

A Horse of a Different Color
A Horse of a National Aeronautics and Different Color Space Administration A Horse of a Different Color To celebrate the 23rd anniversary of the Hubble Space Telescope, NASA released a new view of the Horsehead Nebula that provides an intriguing astronomical variation on the phrase, “a horse of a different color.” The Horsehead Nebula, also known as Barnard 33, was first recorded in 1888 by Williamina Fleming at the Harvard College Observatory. Visible-light images show a black silhouette, a “dark nebula,” that resembles a horse’s head. Dark nebulae are generally most noticeable because they block the light from background stars. Two views of Horsehead Nebula To see deeper into dark nebulae, astronomers use infrared These two images reveal different views of the Horsehead Nebula. The visible-light image on the left was taken by a ground-based light. Hubble’s infrared image of the Horsehead transforms telescope. The near-infrared image on the right was taken by the the dark nebula into a softly glowing landscape. The image Hubble Space Telescope. reveals more structure and detail in the clouds. In the image at left, the gas around the Horsehead Nebula shines Many parts of the Horsehead Nebula are still opaque at infrared a bright pink, in contrast to the darkness of the Horsehead itself. This pink glow occurs along the edge of the dark cloud and is wavelengths, showing that the gas is dense and cold. Within created by the bright star, Sigma Orionis, above the Horsehead, such cold and dense clouds are regions where stars are born.

Horsehead Nebula, in Infrared Light, from Hubble
Horsehead Nebula, in Infrared Light, from Hubble Hubble, the orbiting space telescope, turned 23 years old in April of 2013. To celebrate the anniversary of its launch, NASA released this amazingly detailed image of the Horsehead Nebula which Hubble took in infrared light. NASA provides a more detailed description of this stunning image: While drifting through the cosmos, a magnificent interstellar dust cloud became sculpted by stellar winds and radiation to assume a recognizable shape. Fittingly named the Horsehead Nebula, it is embedded in the vast and complex Orion Nebula (M42). A potentially rewarding but difficult object to view personally with a small telescope, the above gorgeously detailed image was recently taken in infrared light by the orbiting Hubble Space Telescope in honor of the 23rd anniversary of Hubble's launch. The dark molecular cloud, roughly 1,500 light years distant, is cataloged as Barnard 33 and is seen above primarily because it is backlit by the nearby massive star Sigma Orionis. The Horsehead Nebula will slowly shift its apparent shape over the next few million years and will eventually be destroyed by the high energy starlight. Click on the image to enjoy a much-larger-and-clearer view. Credits: Image of the Horsehead Nebula, taken by Hubble in infrared light, by NASA, ESA, and The Hubble Heritage Team (STSci / AURA).

Planck Highlights the Complexity of Star Formation 26 April 2010
Planck highlights the complexity of star formation 26 April 2010 The first image covers much of the constellation of Orion. The nebula is the bright spot to the lower centre. The bright spot to the right of centre is around the Horsehead Nebula, so called because at high magnifications a pillar of dust resembles a horse's head. The giant red arc of Barnard's Loop is thought to be the blast wave from a star that blew up inside the region about two million years ago. The bubble it created is now about 300 light-years across. In contrast to Orion, the Perseus region is a less vigorous star-forming area but, as Planck shows in the other image, there is still plenty going on. The images both show three physical processes This is an active star-formation region in the Orion taking place in the dust and gas of the interstellar Nebula, as seen By Planck. This image covers a region medium. Planck can show us each process of 13x13 degrees. It is a three-color combination separately. At the lowest frequencies, Planck maps constructed from three of Planck's nine frequency emission caused by high-speed electrons channels: 30, 353 and 857 GHz. Credit: ESA/LFI & HFI interacting with the Galaxy's magnetic fields. An Consortia additional diffuse component comes from spinning dust particles emitting at these frequencies. New images from ESA's Planck space observatory reveal the forces driving star formation and give astronomers a way to understand the complex physics that shape the dust and gas in our Galaxy.

The Angular Size of Objects in the Sky
APPENDIX 1 The Angular Size of Objects in the Sky We measure the size of objects in the sky in terms of degrees. The angular diameter of the Sun or the Moon is close to half a degree. There are 60 minutes (of arc) to one degree (of arc), and 60 seconds (of arc) to one minute (of arc). Instead of including – of arc – we normally just use degrees, minutes and seconds. 1 degree = 60 minutes. 1 minute = 60 seconds. 1 degree = 3,600 seconds. This tells us that the Rosette nebula, which measures 80 minutes by 60 minutes, is a big object, since the diameter of the full Moon is only 30 minutes (or half a degree). It is clearly very useful to know, by looking it up beforehand, what the angular size of the objects you want to image are. If your field of view is too different from the object size, either much bigger, or much smaller, then the final image is not going to look very impressive. For example, if you are using a Sky 90 with SXVF-M25C camera with a 3.33 by 2.22 degree field of view, it would not be a good idea to expect impressive results if you image the Sombrero galaxy. The Sombrero galaxy measures 8.7 by 3.5 minutes and would appear as a bright, but very small patch of light in the centre of your frame. Similarly, if you were imaging at f#6.3 with the Nexstar 11 GPS scope and the SXVF-H9C colour camera, your field of view would be around 17.3 by 13 minutes, NGC7000 would not be the best target.

This work is conducted as part of the “SPECPDR” program dedicated to the study of very small particles and chemistry in photo-dissociation regions with the Spitzer Space Telescope (SST). Aims. We study the evolution of the Aromatic Infrared Bands (AIBs) emitters across the illuminated edge of the Horsehead nebula and especially their survival and properties in the HII region. Methods. We present spectral mapping observations taken with the Infrared Spectrograph (IRS) at wavelengths 5.2–38 µm. The spectra have a resolving power of λ/∆λ = 64–128 and show the main aromatic bands, H2 rotational lines, ionised gas lines and continuum. The maps have an angular resolution of 3.6–10.6 and allow us to study the nebula, from the HII diﬀuse region in front of the nebula to the inner dense region.
