COMET ISON SOME SAY BRIGHTEST EVER COMET

KING JESUS IS COMING FOR US ANY TIME NOW. THE RAPTURE. BE PREPARED TO GO.

SIGNS OF THE END OF THE AGE (NOT THE WORLD) THE WORLD GOES ON FOREVER.

GENESIS 1:5,14
5 And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:(ISRAELS HOLY DAYS AND SABBATH STARTS AT 6PM) And for SIGNS (PROPHECY SIGNS TO HAPPEN IN THE FUTURE, OUR DAY)

SIGNS IN THE SUN, MOON AND STARS-CHEMICAL WEAPONS

LUKE 21:11
11 And great earthquakes shall be in divers places, and famines, and pestilences;(BIOLOGICAL/CHEMICAL/NUCLEAR) and fearful sights and great signs shall there be from heaven.

Comet of the Century' Speeds to Earth: New Hubble Image of ISON

First Posted: Jul 18, 2013 10:31 AM EDT
Comet ISON
This image of Comet ISON was made by NASA's Hubble Space Telescope on April 30, 2013, when the comet was about 400 million miles from Earth and about 363 million miles from the Sun between the orbits of the planets Mars and Jupiter. (Photo : NASA, ESA, and the Hubble Heritage Team (STScI/AURA))
Comet ISON, dubbed the "comet of the century," is rapidly approaching Earth. With its spectacular tail trailing dust and particles, this comet is expected to shine bright in the sky come November. Yet NASA is getting an early look at ISON; the agency has used the Hubble Space Telescope to observe the comet as it streaks across space.ISON is a comet, which means that it's made up of a combination of ice, frozen dust and gas. As it nears the sun, it trails debris in its wake; this creates the spectacular tail that you can see in Hubble's latest image. The newest image combines two Hubble filters. One filter lets in red light while the other lets in a greenish-yellow color. This allows for the spectacular colors that you can see in the backdrop of space behind the comet.

There's no guarantee that ISON really will be the comet of the century, though. How bright it is largely depends on evaporation rates and how quickly it sheds its dust and water. In April, researchers found that the comet was shedding about 112,000 pounds of dust and 130 pounds of water every minute. At the time, this meant that the water sublimation wasn't yet powering ISON's "jets" since it was still too far away from the sun.Currently, researchers still aren't sure exactly how bright ISON will be. Yet the new image does show that it's continuing its steady trek toward the sun. In the picture, the comet appears fuzzier since the scientists kept the telescope trained on the background stars instead of following the comet. This gives the image the deep, rich background as photons from the Milky Way's stars and even more distant galaxies pile up over time in the same pixels.While ISON's fate is uncertain, it's continuing to journey toward the sun. It's possible that the intensifying solar radiation from the peak of the sun's 11-year solar cycle could potentially help break the comet into pieces. Otherwise, though, ISON will put on a spectacular show in November. Train your eyes on the skies; we may be in for the comet of the century.

Comet ISON month-by-month in late 2013.
By on Jun 13, 2013  
August 2013. As seen from Earth, Comet ISON will be behind the sun in June and July, 2013. When it returns to Earth’s sky in late August, it might be bright enough to be seen by observers using small telescopes at dark locations.

September and October 2013. Comet ISON will brighten as the months pass. In September and October, amateur astronomers will surely be trying to pick it up. The comet will be sweeping in front of the constellation Leo then. It’ll pass first near Leo’s brightest star Regulus, then near the planet Mars. Maybe you can see the comet with binoculars then, and maybe these brighter objects will help you find it.
November 2013. Comet ISON will continue to brighten throughout November as it nears its late November perihelion (closest point to our sun). Comet expert John Bortle wrote on June 13 that he expects the comet to reach visibility to the unaided eye about three weeks before the November 28 perihelion date. In November, ISON will pass very close to the bright star Spica and the planet Saturn, both in the constellation Virgo. These bright stars might help you find the comet. At perihelion, the comet will come within 800,000 miles – 1.2 million kilometers, or about one sun-diameter – of our sun’s surface. If all goes well, and the comet doesn’t fragment, the terrific heating Comet ISON will undergo when it’s closest to our parent star might turn the comet into a very bright object. It may also form a long comet tail around this time. There has been some mention that Comet ISON could even become a daylight object, briefly. Remember, though, at perihelion, Comet ISON will appear close to the sun on the sky’s dome (only 4.4° north of the sun on November 28). Although the comet will be bright, it’s likely that only experts who know how to look near the sun, while blocking the sun’s glare, will see it.

December 2013. This is likely to be the best month to see Comet ISON, assuming it has survived 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. As ISON’s distance from the sun increases, it’ll grow dimmer. Comet expert John Bortle wrote on June 13:
The crescendo of the apparition will likely occur between December 10th and 14th, when the comet will be best seen just before dawn after the moon sets. Although little or perhaps nothing of the head will remain, the huge tail will loom in the northeastern sky. Almost evenly illuminated over its length, this rapidly fading appendage could [span] almost a quarter of the heavens as seen under good, dark observing conditions.
People all over Earth will be able to see it, but it’ll be best seen from the Northern Hemisphere as 2013 draws to a close.

January 2014. Will ISON still be visible to the eye? Hopefully. Only time will tell. On January 8, 2014, the comet will lie only 2° from Polaris — the North Star. And here’s something else that’s fun. On January 14-15, 2014, after the comet itself has passed but when Earth is sweeping near the comet’s orbit, it might produce a meteor shower, or at least some beautiful night-shining or noctilucent clouds.

How bright will Comet ISON be? How long will its tail be? No one can answer these questions yet, but many are excited about this comet, and many astronomers are talking about it. Some are beginning to speak of media hype that always surrounds events of this kind. In his June 13 article published at skyandtelescope.com, comet expert John Bortle explained the reason we can’t know yet how bright Comet ISON will be:
A close solar pass can disrupt and evaporate a comet’s nucleus completely. The intrinsically faintest sungrazer to survive its brush with the sun reasonably intact was Comet Ikeya-Seki in 1965. The long-tailed sungrazers seen in 1880 and 1887 experienced total disruption of their nuclei and dissipated completely within weeks after perihelion. The latest observations of Comet ISON suggest that it’s intrinsically about as bright as those 19th-century objects, so the survival of its head much beyond November 28 is in question.
However, ISON is decidedly brighter than the recent Comet Lovejoy, which totally disrupted and, despite this or perhaps because of it, put on a spectacular long-tailed show for Southern Hemisphere observers at the end of 2011.
Bortle also said that – from January through May of this year – Comet ISON did not brighten as much as astronomers had predicted it would, as it makes its way toward the inner solar system. The comet is not visible in June or July (the sun is between us and it), but it will be back in view around the end of August. You can be sure astronomers will be watching then to see how bright it appears at that time.

Who discovered Comet ISON? Eastern European and Russian astronomers announced the new comet on September 24, 2012. Discovery magnitude was 18.8 – in other words, extremely faint. Vitali Nevski of Vitebsk, Belarus and Artyom Novichonok of Kondopoga, Russia spotted the comet on CCD images obtained on September 21 with a 0.4-m f/3 Santel reflector of the International Scientific Optical Network (ISON) near Kislovodsk, Russia. Afterwards, astronomers at Remanzacco Observatory in Italy confirmed the comet’s presence with the image above.
Comet Lovejoy was a sight to behold from Earth's Southern Hemisphere in late 2011. Here the comet is reflected in the water of Mandurah Esturary near Perth on December 21, 2011. Image Credit: Colin Legg.

Will Comet ISON live up to expectations? Comet ISON might break up into fragments, as the much-hyped Comet Elenin did around August 2011.On the other hand, Comet ISON might survive its encounter with the sun as Comet Lovejoy did in late 2011. If so, it might go on to illuminate our skies with its beauty. And there is one thing we can count on. That is, if Comet ISON does become a bright comet, visible to the eyes of watching earthlings, it will be beautiful. All bright comets are.No doubt about it … comets have a mystique. Once considered omens of doom, we now know them as icy visitors from the outer solar system that sweep near our sun, then disappear again into the depths of space, perhaps never to return. People get excited about comets. They are temporary visitors to our region of the solar system. This comet will be no exception.Bottom line: Comet C/2012 S1 (ISON) is headed for a close encounter with our sun in 2013 and might become a spectacular sight from all of Earth around November and December of this year. Or it might not. This post contains a month-by-month viewing guide, some history of the comet, and a word about what to expect from Comet ISON.

Cosmic radio bursts point to cataclysmic origins

IMAGE: CSIRO's Parkes radio telescope, which has been used to confirm a population of Fast Radio Bursts, is shown superimposed on an image showing the distribution of gas in our Galaxy....

Mysterious bursts of radio waves originating from billions of light years away have left the scientists who detected them speculating about their origins.The international research team, writing in the journal Science, rule out terrestrial sources for the four fast radio bursts and say their brightness and distance suggest they come from cosmological distances when the Universe was just half its current age.The burst energetics indicate that they originate from an extreme astrophysical event involving relativistic objects such as neutron stars or black holes.
Study lead Dan Thornton, a PhD student at England's University of Manchester and Australia's Commonwealth Scientific and Industrial Research Organisation, said the findings pointed to some extreme events involving large amounts of mass or energy as the source of the radio bursts.He said: "A single burst of radio emission of unknown origin was detected outside our Galaxy about six years ago but no one was certain what it was or even if it was real, so we have spent the last four years searching for more of these explosive, short-duration radio bursts. This paper describes four more bursts, removing any doubt that they are real. The radio bursts last for just a few milliseconds and the furthest one that we detected was 11 billion light years away."
Astonishingly, the findings -- taken from a tiny fraction of the sky -- also suggest that there should be one of these signals going off every 10 seconds. Max-Planck Institute Director and Manchester professor, Michael Kramer, explained: "The bursts last only a tenth of the blink of an eye. With current telescopes we need to be lucky to look at the right spot at the right time. But if we could view the sky with 'radio eyes' there would be flashes going off all over the sky every day."The team, which included researchers from the UK, Germany, Italy, Australia and the US, used the CSIRO Parkes 64metre radio telescope in Australia to obtain their results.Co-author Professor Matthew Bailes, from the Swinburne University of Technology in Melbourne, thinks the origin of these explosive bursts may be from magnetic neutron stars, known as 'magnetars'. He said: "Magnetars can give off more energy in a millisecond than our Sun does in 300,000 years and are a leading candidate for the burst."The researchers say their results will also provide a way of finding out the properties of space between the Earth and where the bursts occurred. Author Dr Ben Stappers, from Manchester's School of Physics and Astronomy, said: "We are still not sure about what makes up the space between galaxies, so we will be able to use these radio bursts like probes in order to understand more about some of the missing matter in the Universe. We are now starting to use Parkes and other telescopes, like the Lovell Telescope of the University of Manchester, to look for these bursts in real time."
