Is ISON really 'dead'? New images reveal glowing trail of dust that could be a surviving fragment of the comet

  • At around 6.35pm GMT the Comet ISON flew towards the sun 

  • Astronomers predicted the heat would cause it to disintegrate and initial images appeared 

  • to 

  • confirm this 

  • Yet shortly after the flyby unusual lights were seen suggesting otherwise

  • Scientists are now unsure what happened to the 'comet of the century'

  • The demise of Comet ISON was deemed inevitable, with scientists around the world saying it would disintegrate as it flew close to the sun. 
    However, the latest images from Nasa and the European Space Agency suggest that the comet, or at least fragments of it, may have survived. 
    At around 6.35pm GMT on Thursday, the so-called 'comet of the century' was spotted on a trajectory towards the sun before seeming to disappear.
    Yet, shortly afterwards bright lights were spotted that some scientists have claimed could be the comet's nucleus. 

  • 'Initially when something came out (after close approach), we thought this is just the dust trail and there's not much left, it's just going to fade away,' astronomer Matthew Knight told CBS News
    'And then images keep coming in and...the last few, it seems pretty definitely like it's getting brighter. So we do not have a good answer as to what's going on.'

  • Some scientists feared the delicate comet had already started to disintegrate, even before it grazed the 'surface' of the sun, 1.2 million kilometres away.
    Dr Dan Brown, an expert in astronomy at Nottingham Trent University, told MailOnline that when the comet entered the sun's hottest outer layers it was exposed to a temperature of several million degrees.

  • Earlier this week, NASA released a high-resolution image of the streaking comet that looked like a swimming tadpole. 
    It was captured by the H-1 camera on board NASA's Solar Terrestrial Relations Observatory on November 21. 
    Nasa said ISON, which is officially labelled as Comet C/2012 S1, appeared to still be intact in its video and can be seen in these images along with Earth, Mercury and Comet 2P/Encke.
    The tails streaking out from behind both comets can be seen moving along with the steady stream of particles - called the solar wind - that flows out from the sun.


  • If it has survived, ISON, pronounced EYE'-sahn, should be visible with the naked eye through December, at least from the Northern Hemisphere.
    Discernible at times in November with ordinary binoculars and occasionally even just the naked eye, it already has dazzled observers and is considered the most scrutinised comet ever by NASA. 
    But the best is, potentially, yet to come if the comet really has survived its solar flyby. 
    Dr Brown told MailOnline: 'This close encounter with the sun offers a unique opportunity for astronomers to analyse the composition of a comet. Comets are icy, dusty snowballs - the remains from the formation of our solar system 4.5 billion years ago. 
    'The long tail containing the material frozen in the comet and released through the heat of the sun offers astronomers the chance to identify different elements.
    'It has already been bright enough for astronomers to capture amazing pictures. However, if the comet survives its burning close encounter with the sun it may have a huge and impressively long tail with a brightness that might make it an easy to spot object even with the naked eye.

    'This happened in 1965 with the comet Ikeya Seki that had an enormously long tail; but some comets, like Lovejoy three years ago, have been ripped apart during their close encounter by the sun's gravitational force.  
    'The magic limit for survival of the comet seems to be the size, which has to exceed 2 km so it does not get boiled away or ripped apart by the sun. ISON is estimated to be that size, so we should all cross our fingers and await our early Christmas comet,' he said.


  • Detected just over a year ago, the comet is passing through the inner solar system for the first time. Still fresh, this comet is thought to bear the pristine matter of the beginning of our solar system. 
    It's believed to be straight from the Oort cloud on the fringes of the solar system, which is home to countless icy bodies - most notably the frozen balls of dust and gas in orbit around the sun known as comets.
    For whatever reason, ISON was propelled out of this cloud and drawn toward the heart of the solar system by the sun's intense gravitational pull.
    The closer the comet gets to the sun, the faster it gets and in January, it was clocked at 40,000 mph (64,000 kph). 
    By last Thursday, the comet had accelerated to 150,000 mph (240,000 kph) but by the time ISON slingshots around the sun, it will be moving at a mind-boggling 828,000 mph (1,332,000 kph).


  • Whether it has survived or is torn apart, humans have nothing to fear.
    The comet will venture no closer to us than about 40 million miles (64 million kilometres), less than half the distance between Earth and the sun. 
    The closest approach to Earth will occur on Boxing day - if the comet has survived. 
    Then it will head away in the opposite direction forever, given its anticipated trajectory.
    ISON is named after the International Scientific Optical Network, used by a pair of Russian astronomers to detect the comet in September 2012, but it officially is known as C/2012 S1, which indicates when it was discovered. 
    Take heart: The 'C' means it is not expected here again.



    The place to see the ‘comet of the century’ is in a clear dark sky where the horizon is unobstructed, such as in the countryside.
    It can be seen with the naked eye, but binoculars will highlight details such as its tail, streamers and bumps in the surface.
    It should be seen before dawn in the eastern sky.
    ISON passed within 1.2 million miles of the sun’s surface yesterday at around 18:35 GMT.

     'Mediterranean diet with no breakfast best for 

    diabetics '

    For patients with diabetes ,it is better to eat a single large meal than several smaller meals through out the day ,a new study has found .

               Researchers at Linkoping   University in Sweden studied the effect on blood glucose ,blood lipids and different hormones after meals were compared using three different micro -nutrients compositions in patients with type 2 diabetes .

            The three diets were a low -fat diet , a low carbohydrate diet and a Mediterranean diet .The scientists included 21 patients that tested all three diets in a randomised order .During each test day blood samples were collected at six time points .

            The low -fat diet had a nutrient composition that has traditionally been recommended in the Nordic countries ,with about 55% of the total energy from carbohydrates . 

              The low carbohydrate diet had a relatively low content of carbohydrate ;approximately 20 per cent of the energy came from fat .

             The Mediterranean diet was composed of only a cup of black coffee for breakfast ,and with all the caloric content corresponding to breakfast and lunch during the other two test days accumulated to one large lunch .

           Furthermore ,the total caloric content included energy from 150 ml (women )to 200 ml (men )of French red wine to injest with the lunch.

           The food in the Mediterranean diet had an energy content from carbohydrate that was intermediate between the low fat -diet and the low carbohydrate meals ,and sources of fat were mainly olives and fatty fish .

              "The researchers  found that the low -carbohydrate diet increased blood glucose levels much less than the low -fat diet but that levels of triglycerides tended to be high compared to the low -fat diet ".

    आखिर क्यों :आसान नहीं रहता है औरतों का कामानन्द प्राप्त होना


    क्रीड़ा-हित आतुर दिखे, दिखे परस्पर नेह |

    पहल पुरुष के हाथ में, सम्पूरक दो देह |

    सम्पूरक दो देह, मगर संदेह हमेशा |
    होय तृप्त इत देह, व्यग्र उत रेशा रेशा |

    भाग चला रणछोड़, बड़ी देकर के पीड़ा |
    बनता कच्छप-यौन, करे न छप छप क्रीड़ा || 

    माहिरों की राय :

    आसान नहीं रहता है औरतों का कामानन्द को  प्राप्त होना 

    आखिर क्यों ?

    अमूमन पुरुष यौन -दक्ष नहीं होते हैं। काम -कला से पूरी तरह वाकिफ ही नहीं होते हैं। अलावा इसके मनो -सामजिक वजहें भी आड़े आती हैं औरत न दिल की कह पाती है न मर्द समझ पाता है। काम -शिखर पर पहुंचना और उसका अभिनय करना दो अलग अलग बातें हैं। औरत कई मरतबा अपने मर्द की हिफाज़त के लिए भी यह स्वांग भरती है .ताकि उसकी मर्दानगी उसका हम आहत न हो।बचाव करते करते खुद हीन  भावना से ग्रस्त हो जाती है खुद को ही कुसूरवार मान बैठती है।अपना नसीब भी।  

    कुदरत के नियमों के अनुसार दोनों के शरीर परस्पर एक दूसरे  के सम्पूरक हैं एक दूजे के लिए बने भी हैं। यौन -शिखर तक दोनों को सहज रूप पहुंचना चाहिए। 

    अक्सर पहल पुरुष के हाथ में ही रहती है उसका लैंगिक उत्तेजन भी स्पष्ट  सीधा सपाट होता है। काम शिखर को छूना और वापसी भी लेकिन औरतों के मामले में ऐसे कोई स्पष्ट   संकेत नहीं मिलते न ही  कोई ऐसे बायो -मार्कर्स ही हैं ,जो हैं भी वह गोपन बने रहते हैं मर्द उनसे वाकिफ ही नहीं होता। vaginal contractions  ऐसा ही एक मार्कर है। 

    अराउज़ल टाइम (यौन रूप से उत्तेजित  होने दिखने की अवधि ,कामक्रीड़ा के लिए आतुरता )औरत का लंबा रहता है। यहीं पर यौन प्रोद्योगिकी ,उत्तेजन प्रदान करने की वैयक्तिक तरकीबों का अपना महत्व रहता है। 

    तमाम बाहरी कारक (external factors )अपना असर रखते हैं।किसी को ईअर लोब्स (कर्ण लोलक )पर हल्का दन्त दवाब उत्तेजन प्रदान करता है। किसी को कांख पर। अन -अन्वेषित रह जाते हैं काम उत्तेजन केंद्र अक्सर लव हेंडिल्स में ही अटकके रह जाता है मर्द। 

    पुराना रिश्ता है मर्द का प्राथमिक आहार के इन स्रोतों (स्तनों ,वक्ष स्थल से ) लेकिन कामोत्तेजना के एकाधिक स्थल गुह्य ही रह जाते हैं ऐसे में multiple orgasm की कौन कहे यौन शिखर तक एक बार पहुंचना भी बा -मुश्किल से किसी किसी को नसीब होता है। 

    दुनिया में ऐसा कहाँ सबका नसीब है ,

    कोई कोई अपने पीया के करीब है। 

    दूर ही रहते हैं यौन किनारे ,

    इनको न कोई मांझी पार लगाए। 

    तू है तो ज़िंदगी को ज़िंदगी क़ुबूल है। 

    पुरुष का ध्यान अपने यौन परितोष पर रहता है। काम खत्म पैसा हज़म। लेकिन औरत अब मन मसोस कर पहले की तरह बैठी नहीं रह सकती। बेहतर हो मर्द अपने यौन खोल से बाहर आये। यौन कच्छप न बने। कुरुक्षेत्र के मैदान में टिके रहना उसे सीखना चाहिए। यौन शिखर से जुड़ी  है प्रेम की डोर। दूसरे को प्रेम करना सीखिए।

    (४)New truth: That caffeine high is real

    If you feel that your morning coffee soothes your soul, it's not your imagination: A large 2011 study from the Harvard School ofPublic Health found that women who drank at least two cups of coffee regularly had a 15 percent lower risk of depression than those who didn't drink any coffee—and their risk decreased by 20 percent when they downed four or more cups of joe a day.

    Caffeine in moderation

    One possible reason: Caffeinetriggers the release of the brain chemical dopamine—important for sharpening focus and improving your outlook. "Coffee also contains plant-based nutrients that function much like a class of drugs that are used to treat depression," Dr. Ramsey says. Of course, he points out, caffeine doesn't affect everyone in the same way, so cut back on java or other caffeinated drinks if you start to get the jitters or sleep poorly. You should also beware the 12 Surprising Sources of Caffeine.

    Anyone who has ever reached for a sugary snack when stressed out or feeling grouchy knows that the solace you get is fleeting: a few minutes of satisfaction followed by the inevitable blood-sugar crash, with added irritability to boot. And, in general, the modern Western diet—high in processed and fried foods, simple carbs, sugars and unhealthy fats—can set you up fordepressionanxiety, and mood swings, a recent study has discovered.

    But plenty of tasty options exist that actually do the opposite:boost your mood and yourenergy, and set you up to perform better, too. "Food choices that you make every day influence your brain's ability to grow and heal," says Drew Ramsey, MD, co-author of The Happiness Diet. "The foundation of good mental healthis good wholesome food." There are ways to navigate the most up-to-date nutritional science to optimize your best choices. It's all about relying on the new truths of eating—and drinking.

    पत्नी में ही प्रेमिका के दर्शन एक पत्नीत्व की ओर ले जाता है 'लव हारमोन 'oxytocin'

    पतली कमर को लम्बी उम्र हो 

    (१)फ़्लैट  बेली बनाये रखने के लिए कमर को कमनीय दर्शनीय कमर बनाये रखने के लिए दिन भर में आप कुल जितनी केलोरी खुराक के ज़रिये ले रहें हैं कमसे कम उसके एक चौथाई की आपूर्ति प्रोटीनों से होती रहे। 

    (२)कई लोगों को हार्ट बर्न (अपच के कारण सीने में जलन ), अम्ल शूल की चपेट में आने के आसार बने  रहते हैं। ऐसे लोगों को abdominal crunches कसरतों से बचना चाहिए। वजह जानियेगा। ऐसी तमाम कसरतें आमाशय में बन्ने वाले तेज़ाब को फ़ूड पाइप (भोजन नाल )की और ले जा सकतीं हैं। 

    (३)बेबी फॉर्मूला को निरापद बनाता है लहसुन 

    साइंसदानों ने पहली मरतबा लहसुन में ऐसे दो यौगिकों का पता लगाया है जो बेबी फार्मूला को संदूषण से (विषाक्त पदार्थों ,टॉक्सिंस ,कांटामिनेन्टस )से बचाये रह सकतें हैं। 

    ब्रिटिश कोलम्बिया विश्वविद्यालय के रिसर्चदानों ने ऐसे दो यौगिकों के नाम diallyl sulfide और ajoene बतलाये हैं। बेबी फॉर्मूला तैयार करते वक्त संदूषण के खतरे को ये मुल्तवी रख सकते हैं। 

    (४)पत्नी में ही प्रेमिका के दर्शन 

    एक पत्नीत्व की ओर ले जाता है 'लव हारमोन 'oxytocin' .यौनाकर्षण को बढ़ाता है यह प्रेम नाम हारमोन। एक अभिनव अध्ययन का यही हासिल है। ऐसे में एक ही खूंटे से बंधे रहने को आतुर रहता है मर्द। 

    Scientists at the Bonn University Medical Center found that if oxytocin is administered to men and they are shown pictures 0f their partner ,the bonding hormone stimulates the reward center in the brain ,increasing attractiveness of the partner ,and strengthening monogamy .
