Ik kan me (een jaar of 15) geleden nog herinneren dat Hale Bopp overvloog. Erg gaaf om te zien zo'n heldere komeet!

Komeet Hale-Bopp (officiële aanduiding C/1995 O1) was waarschijnlijk de meest geobserveerde komeet van de 20e eeuw, en was een van de helderste kometen van de afgelopen paar decennia. De komeet was gedurende lange tijd (18 maanden) met het blote oog zichtbaar. Dit is tweemaal zo lang als de vorige recordhouder, de komeet van 1811.

Hale-Bopp werd op 23 juli 1995 ontdekt op een grote afstand van de zon, wat deed vermoeden dat de komeet wel eens bijzonder helder zou kunnen worden in de omgeving van de zon. Dit deed de komeet ook en was gedurende het voorjaar van 1997 gemakkelijk zichtbaar met het blote oog.

Hale Bopp kan ik me nog wel herinneren maar dacht dat er onlangs ook eentje was die niet lang daarvoor pas was ontdekt. McNaaght ofzo?

Dat was toch eind jaren 90? Staat mij ook nog wel iets van bij.

COMET ISON APPROACHES:

Later this year, Comet ISON could put on an unforgettable display as it plunges toward the sun for a fiery encounter likely to turn the "dirty snowball" into a naked-eye object in broad daylight. At the moment, however, it doesn't look like much. John Chumack sends this picture, taken Jan. 8th, from his private observatory in Yellow Springs, Ohio:



"Comet ISON (C/2012 S1) is currently in the constellation Gemini, moving between the heads of the twins Castor and Pollux," says Chumack. "It is still pretty faint, near 16th magnitude, but don't be fooled by that. This could become one of the best comets in many years."

Comet ISON is a sungrazer. On Nov. 28, 2013, it will fly through the sun's outer atmosphere only 1.2 million km from the stellar surface below. If the comet survives the encounter, it could emerge glowing as brightly as the Moon, visible near the sun in the blue daylight sky. The comet's dusty tail stretching into the night would create a worldwide sensation.

Comet ISON looks so puny now because it is so far away, currently near the orbit of Jupiter. As it falls toward the sun in the months ahead it will warm up and reveal more about its true character. By the summer of 2013, researchers should know whether optimistic predictions about Comet ISON are justified. Possibilities range from "Comet of the Century" to disintegrated dud. Stay tuned!

Russian astronomers discover new huge comet

^{by Boris Pavlishchev and Alexei Lyakhov
Moscow (Voice of Russia) Jan 14, 2013}

Last year, Russian astronomers Vitaly Nevsky and Artyom Novichonok discovered a new gigantic comet that is currently approaching Earth. The ISON comet, which is expected to become brighter than the full moon, will be visible to the naked eye by late 2013.

The astronomers say that given the comet's unique orbit, its origin may be the Oort Cloud, a cluster of frozen rocks and ices surrounding the solar system, located almost a light-year from the Sun.

The comet is currently passing outside Jupiter, gaining speed and becoming brighter by the day. In September 2012, the Russian astronomers spotted what appeared to be a comet in images taken by a telescope that is part of the worldwide International Scientific Optical Network, or ISON, from which the object draws its name.

Thanks to ISON, astronomers can get images taken by remote telescopes in other countries, including in New Mexico, where a Russian automatic observatory is located.

The ISON comet never plunged into the inner solar system, and its surface darkened because of the impact of galactic particles. At the same time, the comet avoided being damaged by the so-called solar wind, which is not the case for the Moon, for example.

Sergei Smirnov, press secretary of the Pulkovo Astronomical Observatory in Russia, says that studying surface of the ISON comet may shed more light on evolution of the Universe.

"In the future, it would be good to have special space vehicles on standby so that they can approach such celestial objects, something that may finally come true given the ongoing development of air navigation," Smirnov says.

Thus far, Comet ISON has only been visible through powerful telescopes. In November 2013, heat from the sun will vaporize ices in the comet's body, creating what could be a spectacular tail that will be visible in Earth's night sky without telescopes or even binoculars from about October 2013 through January 2014.

Another scenario is that Comet ISON could break apart as it nears the sun, failing to produce a tail of ice particles by the end of November. In December, the comet will be growing dimmer, but, assuming it is intact, it will be visible from both hemispheres of Earth.
January 2014 may see a meteor shower produced by streams of debris from the ISON comet.

Ben benieuwd, klein jaartje wachten dus.
