Nasa and the European Space Agency have started their search for the remnants of Comet ISON, the so-called 'Comet of the Century' which combusted just 750,000 miles above the surface of the Sun last week.

It had been hoped that ISON might survive the encounter, and shine brightly in the night skies into December.

But it became clear on Thursday that the icy ball of dust and rock had not been able to withstand the intense heat and radiation, and had mostly broken up by Monday morning.

Fortunately, there is still much that scientists can learn from the comet. Huge amounts of data were gathered before its destruction, and can be used to provide insights into everything from the origins of the Solar System to the nature of comets themselves.

And now scientists at the European Space Agency say there is a 10% chance that pieces of the comet larger than 100m have survived - and may be large enough to continue to study, even as they fly at 828,000mph away from the Sun.

Gerhard Schwehm, who is the head of solar system science operations at ESA, told MailOnline that while the "brilliant display" that astronomers hoped for is no longer likely, interesting (though difficult) science can still be done.

"As the brightness fades, I believe the source is gone. Perhaps there is a fairly big junk left, but depleted of volatiles. These are really difficult to detect," he told the Mail.

The comet was discovered last year by two amateur astronomers using Russia's International Scientific Optical Network (Ison).

It was born in the Oort cloud, a shell of scattered icy objects right at the outermost edge of the Solar System. The cloud is nearly a light year from the sun, a quarter of the distance to our nearest neighbouring star, Proxima Centauri.

Sometimes a comet is nudged out of the cloud by the gravitational tug of a passing star, and sent on a journey taking millions of years that eventually brings it into the inner Solar System.

Computer models show that Ison was one such comet. However, it was unusual in being a first-time visitor and also in a sun-grazing orbit.

The comet's apparent destruction ended a roughly three million year journey from the Oort Cloud at the edge of our Solar System.

  • This new view of Comet C/2012 S1 (ISON) was taken with the TRAPPIST national telescope at ESO's La Silla Observatory on the morning of Friday 15 November 2013. Comet ISON was first spotted in our skies in September 2012, and will make its closest approach to the Sun in late November 2013.

  • This graphic shows the expected location of the comet named C/2012 S1 (ISON) on Nov. 28, 2013. In late November and December of 2013, it could put on a show when heating from the sun could stir up a great deal of icy and dusty material. The comet is not a threat to Earth. At the time of its closest approach to Earth, on Dec. 26, 2013, comet ISON will come no closer than 40 million miles. When considering Earthly endeavors, that's not exactly a ringside seat.

  • Comet Ison Roars Through Leo

    In the early morning of Oct. 25 (6:45 a.m. EDT), NASA's Marshall Space Flight Center in Huntsville, Ala., used a 14" telescope to capture this image of Comet C/2012 S1 (ISON), which is brightening as it approaches the sun. The comet shines with a faint green color just to the left of center. The diagonal streak right of center was caused by the Italian SkyMed-2 satellite passing though the field of view. At magnitude 8.5, the comet is still too faint for the unaided eye or small binoculars, but it's an easy target in a small telescope. At this time of this image, ISON was located in the constellation of Leo the Lion, some 132 million miles from Earth and heading in toward the sun at 87,900 miles per hour.

  • NASA’s Hubble: Galaxies, Comets, and Stars! Oh My!

    Approaching the sun, Comet ISON floats against a seemingly infinite backdrop of numerous galaxies and a handful of foreground stars. The icy visitor, with its long gossamer tail, appears to be swimming like a tadpole through a deep pond of celestial wonders. In reality, the comet is much, much closer. The nearest star to the sun is over 60,000 times farther away, and the nearest large galaxy to the Milky Way is over thirty billion times more distant. These vast dimensions are lost in this deep space Hubble exposure that visually combines our view of the universe from the very nearby to the extraordinarily far away. In this composite image, background stars and galaxies were separately photographed in red and yellow-green light. Because the comet moved between exposures relative to the background objects, its appearance was blurred. The blurred comet photo was replaced with a single, black-and-white exposure. The images were taken with the Wide Field Camera 3 on April 30, 2013. The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA's Goddard Space Flight Center in Greenbelt, Md., manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Md., conducts Hubble science operations. STScI is operated by the Association of Universities for Research in Astronomy Inc., in Washington, D.C.

  • NASA's Hubble Sees Comet ISON Intact

    A new image of the sunward plunging comet ISON suggests that the comet is intact despite some predictions that the fragile icy nucleus might disintegrate as the sun warms it. The comet will pass closest to the sun on Nov. 28. In this NASA Hubble Space Telescope image taken on Oct. 9, the comet's solid nucleus is unresolved because it is so small. If the nucleus broke apart then Hubble would have likely seen evidence for multiple fragments. Moreover, the coma or head surrounding the comet's nucleus is symmetric and smooth. This would probably not be the case if clusters of smaller fragments were flying along. A polar jet of dust first seen in Hubble images taken in April is no longer visible and may have turned off. This color composite image was assembled using two filters. The comet's coma appears cyan, a greenish-blue color due to gas, while the tail is reddish due to dust streaming off the nucleus. The tail forms as dust particles are pushed away from the nucleus by the pressure of sunlight. The comet was inside Mars’ orbit and 177 million miles from Earth when photographed. Comet ISON is predicted to make its closest approach to Earth on Dec. 26, at a distance of 39.9 million miles.

  • Comet ISON Passes Through Virgo

    Comet ISON shines in this five-minute exposure taken at NASA's Marshall Space Flight Center on Nov. 8 at 5:40 a.m. EST. The image has a field of view of roughly 1.5 degrees by 1 degree and was captured using a color CCD camera attached to a 14" telescope located at Marshall. At the time of this picture, Comet ISON was 97 million miles from Earth, heading toward a close encounter with the sun on Nov. 28. Located in the constellation of Virgo, it is now visible in a good pair of binoculars.
