Scientists have developed detailed 3D maps of comets` atmosphere, which has provided a better insight into its chemical nature.
A new data analysis from ESA/NASA Solar and Heliospheric Observatory (SOHO) spacecraft has revealed the final hours of comet 2012/S1 (ISON).
One or more fragments could have gotten detached from comet ISON in the past days, as two wing-shaped features in the comet`s atmosphere suggest.
A comet is heading for a close encounter with the sun later this month, and if it is not vaporized or torn apart, it should be visible to the naked eye in December.
Comet ISON may actually be disintegrating, a new research has revealed.
The newly discovered comet ISON could give sky watchers one of the brightest shows ever in the night sky during its close-up with the Sun beginning November 2013, according to researchers.
