  7. 7. COMET ISON SPECIAL ISSUE Article : Comet ISON – How to observe it visually & photographically By Rishabh Jain I Sr Educator SPACE The buzz is everywhere. The comet of our lifetime is visiting us. Is it going to put up a spectacular show or is it going to go bust? Only time will tell. This is a very small comet which was accidently discovered by two astronomers but it will go very close to the sun, so it is expected that it will show a long tail. Here’s how you can observe it again and again over the small period of time its visible in the winter skies this year. First of all you need some basic instruments to observe it (arranged in accordance to ease of use) Unaided Eyes ( The best tool to observe objects in the sky, while they are bright ) Magnetic Compass ( or a smartphone application that does that ) Binoculars ( 8 x 50 at least ) Small Telescope ( 76mm mirror/lens diameter or higher ) Now that you have any/all of these, you need to know where the comet is going to be in the sky. A wise man says, just follow the given maps and start observing from the third week of November. The comet will take a round about the sun and will return back. (There are different maps for pre and post Perihelion – the closest approach to the sun) To photograph it you will need the following (arranged in accordance to ease of use and cost) Tripod ( must have, comes in handy for binoculars also ) Point and Shoot Camera ( Normal Digital Camera/Phone Camera ) DSLR Camera with a wide angle lens Sky Tracker ( Astrotrac or similar ) 7
  8. 8. It is expected that the comet will get very bright. For the novice users, its best to wait it out till you start seeing the tail of the comet. For the advanced users with a good camera ( DSLR ) you can go full capacity with manually setting your camera. As the earth rotates, the stars in the images will tend to show a drag, which looks cool but if you want clockwork precision – sky trackers are available in the market. A few names are Polarie, Astrotrac, Orion. It is essential to find dark sky to go for such shoots but the comet is expected to get very bright. Some estimates say that It is going to be visible during day time also. Woahhh!! So get ready to hunt this comet down and capture it in your memories (Brain and Camera) forever 8

  16. 16. SCHOOL IN FOCUS – BAL BHARTI PUBLIC SCHOOL, ROHINI With a view to fulfill the persistent demand of residence of the vast residential complex of Rohini, The Child Education Society - the apex body of Bal Bharati Public Schools started the Rohini School in August‘1989. Meanwhile, the school has grown into a full fledged four section based composite Senior Secondary School affiliated to Central Board Of Secondary Education and the first batch of Class XII passed out of the School in 2002. Since its inception in the year 1989 Bal Bharti Public School, Rohini has scaled several heights of success. Under the able guidance of Principal Ms. Rekha Sharma and Vice Principal Mrs. Bandhana Sharma the school’s academic and co- curricular progress has always been progressive. The school has several accolades to its name and accepts all new challenges in its stride. One such endeavor is the induction of Astronomy club in the School in association with SPACE since 2004. The astronomy club is an effort to satisfy the quest to explore. Its primary objective is to give wings to the dreams of our learners and inculcate in them the spirit of scientific inquiry. It also encourages the learning of a multitude of disciplines such as Astronomical Science, History, Geography etc.. Apart from theoretical training the students are given practical sessions wherein they apply the concepts of Space science to acquire new facts. Ms. Rekha Sharma, Principal BBPS Rohini The Astronomy Cub activities involve Night Sky observations, learning how to use equipments like Sun Dial, Planisphere, latitude finder, telescope etc.. Interaction with renowned scientists is also a part of this programme. The significant findings and explorations by the students are generously rewarded. Students were felicitated for preliminary Asteroid Hunt. “The Astronomy Club in our School is becoming increasingly popular among the learners an the credit of this overwhelming response is attributed to SPACE (Science Popularisation Association of Communicators and Educators) with whom we’ve been collaborated since the beginning.” - Sandhya Sachdev, TGT Science BBPS Rohini (Astronomy Cub Coordinator) “With the Space, going Global, the Children are actively participating in the various activities offered and the visit to NASA is being looked up as another feather in their cap” - Bandhana Sharma, Vice Principal BBPS Rohini. 16

  19. 19. COMET ISON SPECIAL ISSUE COVER STORY - WILL COMET ISON KEEP ITS PROMISE? By Biman Basu I Author, Science Communicator and Consultant Within weeks after a new comet was discovered in September last year by Russian astronomers VitaliNevski and ArtyomNovichonok on CCD images made with a 0.4-m telescope of the International Scientific Optical Network (ISON) near Kislovodsk, Russia, astronomers declared that it was going to become the ‘comet of the century’. The comet, named Comet ISON (C/2012 S1), is now racing towards the Sun for its perihelion on 28 November and all eyes are now turned towards it in anticipation of a spectacular show during November end or early December. But will it really live up to our expectations? Many astronomers are not convinced that it will. To find out why this uncertainty, it is necessary to know about comets in general. DIRTY SNOWBALLS A comet is an icy body made up of dust, ice, carbon dioxide, ammonia, methane and other constituents and are often described as ‘dirty snowballs’. Some researchers think comets might have originally brought some of the water and organic molecules to Earth that led to the appearance of life on our planet. Most comets come from far reaches of the solar system – a region known as the Oortcloud, far beyond the orbit of Pluto. Some comets originate in a region known as the ‘Kuiper Belt’ that lies beyond the orbit of the gas giant Neptune. Occasionally a comet streaks through the inner solar system; some do so regularly, some only once every few centuries. Some comets, known as periodic comets, appear regularly after certain intervals, while others known as non-periodic comets appear only once, never to return again. As a comet gets closer to the Sun, it warms up and the ice on the surface of the nucleus begins turning into gas, forming a cloud known as the ‘coma’. Radiation pressure from the Sun pushes dust particles away from the coma, forming the characteristic ‘tail’ of a comet. Some comets also sport an ion tail formed by ions created by the action of charged particles from the Sun on the comet’s gases. Since comet tails are shaped by the solar wind, they always point away from the Sun irrespective of whether the comet is moving towards or away from the Sun. 19
  20. 20. Comets become visible when they pass close to the Sun when their comas and tails reflect sunlight or even glow because of energy they absorb from the Sun. They brighten up as they move closer to the Sun and fade away as they move further away from the Sun. However, most comets are too small or too faint to be seen without a telescope. Comet Halley (1P/Halley) is a famous periodic comet that has been seen several times in recorded history, the last being during 1985-86. In the past century, a score of comets brighter than Comet Halley have been discovered. Yet, most comets appear without warning and are not seen again. Many are periodic comets like Comet Halley, which returns every 76 years or so. But the cycle of most periodic comets are extremely long (thousands or even scores or hundreds of thousand years). For example, the bright Comet Bennett (C/1969 Y1) that lit up the morning skies in 1970 will return in 17 centuries, and the spectacular Comet West (C/1975 V1) will reappear in about 500,000 years. Among the comets that can easily be seen with the unaided eye, Comet Halley is the only one that returns in a single lifetime. More than 200 comets whose periods are between 3 and 200 years are known, but they are or have become too faint to be readily seen without the aid of telescopes. APPEARANCE AND BEHAVIOUR The physical appearances and behaviors of comets are as varied as the appearances and behaviors of people; no two are alike. The brightness and visibility of a comet depend upon the amount of material it contains, which often determines the extent of the tail it sports, and the closeness of its approach to both the Sun and Earth. In some comets the tail may be almost non-existent while others may sprout extensive tails. How bright a comet becomes depends on several factors. Among them is the size and composition its nucleus. This part of a comet, usually only a few kilometers across, is gradually warmed by the Sun’s heat as the comet approaches the Sun and expels gas and dust into space, often in distinct jets. A comet’s activity increases rapidly as it draws closer to the Sun; the brightness typically varies (roughly) as the inverse fourth power of its solar distance. The brightness and apparent size also depend the comet’s distance from Earth. A comet of average size can appear stupendously large and bright if it passes very close to Earth. A case in point is Comet Hyakutake (C/1995 Y1) that appeared in 1996. Coming to within 15 million kilometers of Earth, it reached zero magnitude and was accompanied by a tail stretching out nearly 100° as seen from Earth. 20
  21. 21. But if Hyakutake had approached no closer than Comet Hale-Bopp (C/1995 O1), which was 196 million kilometers from Earth, it would have appeared no brighter than magnitude +6; that is, as bright as the faintest star visible to the naked eye. Conversely, if Hale-Bopp had passed Earth as closely as Hyakutake, it would have blazed at magnitude –6 (3 times brighter than Venus) with a tail stretching across the entire sky! NASA's Hubble Space Telescope took this photo of Comet ISON on 9 October 2013, when the comet was inside Mars’ orbit and about 285 million kilometres from Earth. The nucleus of ISON appears to be intact. [Credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA)] Comet ISON is classified as a Sun-grazing comet, which means it will pass very close to the Sun. As it gets nearer the Sun it is speeding up and will make its closest approach to the Sun, or perihelion, on 28 November 2013 at a distance of only 0.01244 AU (1.2 million km) from the surface of the Sun. In fact, at that distance it will actually pass through the Sun’s outer atmosphere and its surface temperature may exceed that of molten iron (1,538°C). The doubts about the comet’s future arise from this close encounter. If ISON manages to stay in one piece after perihelion, it could put on a memorable sky show around that time. It may emerge as an easy-to-spot, bright early morning object in the eastern sky. Alternatively the comet’s nucleus may disintegrate into a cloud of rubble and ice. In this worst possible case, the comet will rapidly become a dim and fuzzy blob to observers – far from becoming the comet of the century. One of the most legendary letdowns in the history of astronomy happened exactly 40 years ago, in 1973, when the world awaited the arrival of comet Kohoutek (C/1973 E1), discovered by Czech amateur astronomer Luboš Kohoutek early that year. Once the orbit was plotted, astronomers knew that the comet was a first time visitor to the inner solar system and expected it to brighten up sharply after perihelion. But Kohoutek was a dud, never rising to the expected brightness, though it became a modest naked-eye object. Some astronomers feel Comet ISON may also behave in a similar manner. What is more, ISON will pass much closer to the Sun than Kohoutek did and so astronomers may even be able to see its layers come apart like peeling open an onion, using powerful and diverse collection of space and ground based telescopes available today. 21
  22. 22. COMET ISON VISIBILITY Currently, Comet ISON is brightening up as it nears its late November perihelion and is expected to reach unaided eye visibility about three weeks before the 28 November perihelion date. During the month, ISON will pass very close to the bright star Spica (mag. +1.4) and the planet Saturn (mag. +0.7), both in the constellation Virgo and will be visible just before sunrise in the eastern sky. These two bright objects might help in finding the comet. There has been some mention that Comet ISON could become a daylight object, briefly. However, at perihelion Comet ISON will appear too close to the Sun in the sky (only 4.4° north of the Sun on 28 November). Although the comet will be bright, it is likely that only experts, who know how to look near the Sun while blocking the Sun’s glare, may be able to it. Amateurs should take care to avoid looking directly at the Sun while looking for the comet. December is likely to be the best month to see Comet ISON, assuming it survives its close pass near the Sun intact. The comet will be visible both in the evening sky after sunset and in the morning sky before sunrise. The best views could be between 10 and 14 December, when the comet will be best seen just before dawn after the Moon sets. Comet ISON 16 -26 Nov 22
  23. 23. But at that time it may be that little or perhaps nothing of the head will remain and only the huge tail will loom in the eastern sky. During December, the comet will also be visible in the evening. After sunset, just look to the west, or the north-west, and the comet can be seen shining above the horizon in that direction. As ISON’s distance from the Sun increases, it will grow dimmer. If it survives perihelion, Comet ISON may still be visible in January 2014, and if visible, it will be only 2° from Polaris on 8 January. Interestingly, on the night of 14-15 January 2014, after the comet itself has passed, its debris might produce a meteor shower, or at least some beautiful nightshining or noctilucent clouds as Earth sweeps through the comet’s orbit. But it is still too early to predict how Comet ISON will behave after perihelion. We can only keep our fingers crossed and be prepared to see the comet during late November and early December. Comet ISON 1-17 Dec 23
  24. 24. COMET ISON SPECIAL ISSUE ASTROINQUISITES Q. Why should we observe comet ISON? ANSWER: This year, amateur and professional astronomers worldwide are eagerly anticipating comet ISON. Everyone is getting ready with their binoculars and telescopes to observe it. But, have you ever thought why everyone is so excited about it? So, let’s find out what’s the magic behind comet ISON. I. ONE OF THE BRIGHTEST COMETS: From the recent studies done on comet ISON, it is hoped that it will be one of the brightest comet of the century. Comet ISON certainly has the potential to reach significant brightness similar to that of the "Great Comet of 1680", which was visible even in daytime and developed a spectacularly long tail. But, astronomers always had a tough time when it comes to predicting comet behavior. Many "Comet of the century" candidates eventually turned out to be great disappointments. II. ONE TIME COMET: It is estimated that Comet ISON will be seen for the first and the last time this year. It will cross the solar system in 2014 and will never come back as it doesn’t revolve around the Sun periodically (in scientific terms, it is a long period comet). So, this is our first and the last chance to observe it and we are lucky to get such opportunity. 24
  25. 25. III. OBSERVED BY SPACE MISSIONS ON MARS: ISON was the first comet in human history to be observed from more than one planet, on 1 October 2013, the comet passed about 0.072 AU (10.8 million km) from Mars. The Mars Reconnaissance Orbiter made some images with its HiRISE instrument starting on 29 September 2013. IV. It is going very near to the Sun: Like every other comet ever observed, Comet ISON is speeding up as it gets nearer the Sun. Comet ISON will make its closest approach to the Sun, or perihelion, on 28 November 2013 at a distance of only 1.2 million km (about 750 000 miles) from the surface of the Sun. This orbit will actually take the comet through the Sun’s outer atmosphere and its surface temperature may exceed that of molten iron (1538 °C). If the comet survives this very close encounter, it may emerge as an easily spotted early morning object. So, Get Ready To Observe The “Comet Of The Century”! 25
  26. 26. COMET ISON SPECIAL ISSUE ASTRONOMY AT HOME Comet Making This time we are going to make a Comet. But before that we must know what a Comet is? A Comet is an icy small Solar system body that, when passing close to the Sun, heats up and begins to outgas, displaying a visible atmosphere or coma, and sometimes also a tail. A Comet is also known as a “Dirty Snowball” or in Hindi we call it a “Keechad ka lodoo”. The solid, core structure of a comet is known as the nucleus. Cometary nuclei are composed of an amalgamation of rock, dust, water ice, and frozen gases such as carbon dioxide, carbon monoxide, methane and ammonia. It also consist a very important nutrient for a body to develop i.e. proteins. 26
  27. 27. Now, let’s start with our Comet. First of all arrange the following material 2 cups Mud 3 cups water Doctor/Laboratory gloves 2 bottle caps Soya Sauce 1 bottle cap Ammonia/Colin 3 cups Dry Ice PROCEDURE: Before you start making the comet, you need to wear the doctor/laboratory gloves as it will be required while handling the dry ice. STEP 1 - Add 2 cups of Mud to a Zip lock bag and add 3 cups of Water to make thick slurry. Mud is added to stimulate dust component in the comet. 27
  28. 28. STEP 2 - Add 1 bottle cap of Ammonia to the slurry. Liquid ammonia is added for simulating the Ammonia Ice in the comet. You can also use Colin or any other surface cleaning liquid as they contain ammonia STEP 3 - Proceed further by adding two bottle caps of Soya Sauce and mix the slurry to make it homogenous. The Soya Sauce is a good source of Proteins hence amino acids. 28
  29. 29. STEP 4 - Make a neck by holding the bag at the point where slurry occupies volume leaving no space for air. STEP 5 - Put 2 cups of powdered Dry Ice in the cone formed above. It is added to simulate carbon-dioxide ice in the comet. 29
