What happened as Comet ISON passed the sun?
As the comet approached the sun, its fragment cloud was pulled out considerably, with the pieces closest to the sun moving faster than those far behind. After the comet dimmed, it then brightened up briefly when the pieces clumped together again after passing the sun.
Did comet ISON survive?
Comet Ison appears to have survived a close encounter with the sun that had threatened to vaporise it. The remnant could now go on to be visible from Earth in December, but astronomers do not know how bright it might become.
Why are scientists so interested in Comet ISON?
Solar scientists, like Bryans, are interested in comets like ISON because they can act as probes into the mysterious solar corona. How they behave on their journey past the Sun can offer insight into the corona’s composition and the behavior of the Sun’s magnetic field.

What is the size of Comet ISON?
How big is it? Measurements taken by the Hubble Space Telescope in April indicate ISON has a nucleus that is 3 to 4 miles across. The comet’s head, or coma, is estimated to be 3,100 miles across, or 1.2 times the width of Australia.
How big was the ISON comet?
What is the shortest period comet?
Comet Encke has the shortest orbital period of any known comet within our solar system.
What has Soho done in space?
Over more than two decades in space, SOHO has made many new discoveries, adding to scientists’ understanding of our closest star. Up-to-date views of the sun from the Solar and Heliospheric Observatory.
What is the SOHO mission?
Launched in December 1995, the joint NASA-ESA Solar & Heliospheric Observatory mission — SOHO — was designed to study the Sun inside out, from its internal structure, to the extensive outer atmosphere, to the solar wind that it blows across the solar system.
What happened to Ison?
C/2012 S1 (ISON) was the subject of the most coordinated comet observing campaign in history. Over the course of a year, more than a dozen spacecraft and numerous ground-based observers collected what is believed to be the largest single cometary dataset in history as ISON plunged toward a close encounter with the Sun.
What happened to Comet ISON?
The much-anticipated flyby of the sun by Comet ISON on Thanksgiving Day 2013 is over, and instead of becoming a Great Comet…. “Comet ISON fell apart,” reports Karl Battams of NASA’s Comet ISON Observing Campaign.
