Trivia | Prescott Astronomy Club

Dr. Geraint Jones of University College, London and his team used 2007 data from the now-inoperable Ulysses spacecraft, which was able to gauge the size of the region of space disturbed by the comet's presence.
Ulysses encountered McNaught's tail of ionized gas at a distance downstream of the comet's nucleus more than 225 million kilometers. This is far beyond the spectacular dust tail that was visible from Earth in 2007. "It was very difficult to observe Comet McNaught's plasma tail remotely in comparison with the bright dust tail," said Jones, "so we can't really estimate how long it might be. "The scale of an active comet depends on the level of outgassing rather than the size of the nucleus," said Jones. "Comet nuclei aren't necessarily active over their entire surfaces; what we can say is that McNaught's level of gas production was clearly much higher than that of Hyakutake." Jones presented his findings at the RAS National Astronomy Meeting in Glasgow, Scotland.
