Comet ISON Speeding Toward The Sun

Nov 28, 2013 – Comet ISON, a shopping-mall-sized chunk of dust and ice that makes its closest approach to the sun Thursday, is refusing to show its hand. Researchers know it will skim roughly 1 million miles from the fiery solar surface around 1:30 p.m. ET, but what will happen next is the subject of feverish scientific speculation. Comet ISON has moved quite close to the sun in this image from ESA/NASA’s Solar and Heliospheric Observatory captured at 10:51 a.m. EST on Nov. 28, 2013. This image is a composite, with the sun imaged by NASA’s Solar Dynamics Observatory in the center, and SOHO showing the solar atmosphere, the corona. (Credit Image: © SOHO/NASA/ZUMA24.com)
