Editorial column

Dear Students,

This is the Diwali and New Year time. But as our Honourable Chairman Shri Pravinkaka told in the student management meeting that don’t wait for the special day to begin your exam preparation, start your preparation from the 1st day of the New Year, so that whole year can be utilized fully.

So, dear all, your faculties had worked very hard to give you the best in their subjects in all the regular and extra lectures. We had guided you from time to time about the important topics for exam and had solved all the exam questions. We had taken three mid sem exam and one pre GTU to mentally boost your confidence level. We have tried to make best preparation for you all.

Now, it’s your time to give your best. Please make sincere efforts so that you can feel contented after giving exam and then can be successful later. Try not to waste your time. Don’t wait for the last moment preparation. Never think of tomorrow. Start your preparation today. Even if you feel that you have completed your preparation, revise the things. Be confident and do hard work: Success will be yours. We will pray that besides ranks and a good percentage you will have a smile on your face!

We all are waiting for your best results. We expect your rank in the GTU ; as well as an increase in the pass percentage and decrease in the fail percentage. Hope you all do well and emerge with flying colors.

This Diwali, may you be blessed with good fortune as long as Ganeshji's trunk, wealth and prosperity as big as his stomach, happiness as sweet as his ladoos and may your trouble be as small as his mouse.

Have a prosperous Diwali. Hope this festival of lights, brings you every joy and happiness. May the lamps of joy, illuminate your life and fill your days with the bright sparkles of peace, mirth and goodwill, because you are someone who deserves life's best and so much more. Have a joyous Diwali and New Year.

On behalf of all the staff members of VVP EC parivar, I wish you all the best in the ensuing examinations.

"WISH U A VERY HAPPY DIWALI and NEW YEAR"

Kindly keep sending your feedback, suggestion to us.

POST DIWALI NIGHT-SKY SPECTACLE- COMET ISON

2013 can be called a year of comets. Early in the year a faint comet called LEMMON appeared followed closely by another one called PanSTARRS in March. The two comets lined up in the evening sky in mid March producing a once in a life time view for astronomers both professional and amateur. Not much is known by the general public about these two comets as they were not known outside the astronomical community. But the show stopper of 2013 is definitely on its way and its name is ISON-C/2012 S1 to be accurate. This comet is going to put up a show that has not been seen by an entire generation. Before going into what ISON will look like and how it will appear the first question arises that what are comets? Briefly put comets are leftovers of solar system. The material left after all the planets and their moons were formed can be classified into two broad types-comets (Dhumketu) and Asteroids (Laghugruh).

The basic difference between comets and asteroids is their point of origin. Comets have been formed in very distant parts of the solar system-further than the orbit of Pluto (Yam) whereas the asteroids have formed near to the sun. The fact that asteroids are formed very near to the Sun has stripped them of all gaseous contents and thus these are solid heavy stony or metallic bodies. The chief concentration of asteroids is found between the orbits of planets Mars (Mangal) and Jupiter (Guru/ Brihaspati) and thus this region is rightly called asteroid belt. Comets on the other hand being formed in far regions of the solar system got to keep their gaseous contents in the form of ice. A very common term used for comets is dirty snowballs as they are made up of rocks and ice made up of water, carbon dioxide, hydrogen etc. Comets when come close to the Sun, produce a characteristic tail which is actually their ice subliming to form gas which is pushed in the direction opposite to the Sun by solar radiation pressure. Thus comets are also called Puchhadiyo Taro. Asteroids being devoid of any volatile material do not produce tail. Comets reside in two different locations- the Kuiper belt just outside the orbit of Pluto at a distance of 30 to 50 Astronomical Unit or AU (Khagoliya Ekam) where 1 AU = 15 crore km which is the average Sun-Earth distance. The other location of comets is the very distant Oort cloud located at an average distance of 50,000 AU from the Sun.

The comets that come from the Kuiper belt are termed short period comets as

they come into the inner solar system in time periods of some tens to hundreds of years. The Oort cloud comets on the other hand are termed long period comets having periods of excess of thousands of years.

e-Bulletin – EC Department VOL. 2, NO.3 - Quarterly – JULY 2013 15

ISON is a fresh comet from the Oort cloud heading towards the Sun for its first trip. Its path found to be highly hyperbolic suggests that it might never return again. ISON stands for International Scientific Optical Network which is a chain of computer controlled robotic telescopes that search the skies for small objects that might be potentially dangerous for Earth. Many such robotic survey telescopes operate in different parts of the world like the PanSTARRS (Panoramic Survey Telescope and Rapid Response System), LSST (Large Synoptic Survey Telescope), CSS (Catalina Sky Survey) etc. New comets discovered by such networks are side products of these facilities. ISON was discovered on 21 September 2012 by the Russia based 16 inch ISON chain telescope.

This comet falls in a special category of “Sungrazing comets”-comets which

whiz past the Sun passing through its atmosphere. The closest point to the sun for a body moving around it is termed as Perihelion. ISON will be only 11 lakh km away from the surface of the sun during perihelion which will occur on 28 November 2013. 11 lakh km can be considered a bullet near the ear in the light of the fact that the sun itself has a diameter of about 14 lakh km. ISON will be a naked eye object in early November (most probably 7-8 November) when it will be visible in the morning sky. It will keep on growing brighter and brighter but moving towards the Sun and thus difficult to pick up. On 28 November 2013 it will be nearest to the Sun and thus brightest but being only 1 degree from the Sun it will be impossible to see. It will put up a grand show from roughly about 5 to 8 December lasting up to first week of January 2014 after which it will fade in to oblivion forever.

e-Bulletin – EC Department VOL. 2, NO.3 - Quarterly – JULY 2013 16

The peak show would be from 10 to 14 December when it will be in the moon

less sky and the comets tail would be half the heavens long in north-eastern sky spanning upto the constellation of Ursa Major (Saptarishi). But all these are just mere estimates as comets are notorious for their unpredictable behavior. There is also a slim chance that ISON might not make it out from its perihelion and the Sun might break it into pieces or even worse-engulf it completely. On a whole the best we can do is wait and see. 2nd December is amavasya (new moon) thus during the first week of December the shukla paksha moon would be quite small and setting with the sun giving dark eastern sky which is where ISON would be post perihelion.

The best view would be through a good quality binocular or a small telescope but it can be enjoyed even with naked eyes. If you do not have access to any of the equipment above check for local astronomy club which might be arranging public sessions for the event. Happy comet hunting!!!

Ten Important Comet Facts

1. Comets are in orbit around the Sun as are our planets. 2. Comets are composed of ices, dust and rocky debris carried from the early formation of the solar

system about 4.5 billion years ago. 3. Comets are remnants from the cold, outer regions of the solar system. They are generally thought to

come from two areas - the Oort Cloud and the Kuiper Belt. Both of these are areas where materials left over from the formation of our solar system have condensed into icy objects. Both regions extend beyond the orbits of Neptune and Pluto but are still part of our solar system and much closer to us than the closest star.

4. Comet orbits are elliptical. It brings them close to the sun and takes them far away. 5. Short period comets orbit the Sun every 20 years or less. Long period comets orbit the Sun every 200

years or longer. Those comets with orbits in between are called Halley-type comets. 6. Comets have three parts: the nucleus, the coma and the tails. The nucleus is the solid center

component made of ice, gas and rocky debris. The coma is the gas and dust atmosphere around the nucleus, which results when heat from the Sun warms the surface of the nucleus so that gas and dust spew forth in all directions and are driven from the comet's surface. The tails are formed when energy from the Sun turns the coma so that it flows around the nucleus and forms a fanned out tail behind it extending millions of miles through space.

7. We see a comet's coma and tail because sunlight reflects off the dust (in the coma and dust tail) and because the energy from the Sun excites some molecules so that they glow and form a bluish tail called an ion tail and a yellow one made of neutral sodium atoms.

8. Scientists have seen comets range in size from less than 1 km diameter to as much as 300 km, although the 300km (called Chiron) does not travel into the inner solar system.

9. We know a comet could impact Earth and that it is important to understand the nature of comets so we can design better methods to protect ourselves from them should one be on a collision path with Earth.

10. A comet nucleus has a dark, sometimes mottled surface but we don't know if it has an outer crust or if it is layered inside. We don't really know what comets are like beneath their surface and that's why we need a mission like Deep Impact.
