NASA Begins Search For What Is Left Of Comet ISON


www.nasa.gov said:

Just prior to its closest approach to the sun on November 28, Comet ISON went through a major heating event, and likely suffered a major disruption. At this time, scientists are not sure how much of the comet survived intact. We may be seeing emission from rubble and debris in the comet's trail, along its orbit, or we may be seeing the resumption of cometary activity from a sizable nucleus-sized chunk of ISON.

Most agree that up to 90 percent of ISON was destroyed, leaving approximately 10 percent of the comet intact. If previous sungrazing comets are any guides, there may be a sizeable piece of comet nucleus left. At this point, though, scientists are waiting for a variety of telescopes to make observations before the status of Comet ISON can be confirmed.

Fire vs. Ice: The Science of ISON at Perihelion


www.nasa.gov said:

After a year of observations, scientists waited with bated breath on Nov. 28, 2013, as Comet ISON made its closest approach to the sun, known as perihelion. Would the comet disintegrate in the fierce heat and gravity of the sun? Or survive intact to appear as a bright comet in the pre-dawn sky?

Some remnant of ISON did indeed make it around the sun, but it quickly dimmed and fizzled as seen with NASA's solar observatories. This does not mean scientists were disappointed, however. A worldwide collaboration ensured that observatories around the globe and in space, as well as keen amateur astronomers, gathered one of the largest sets of comet observations of all time, which will provide fodder for study for years to come.
