I did not see Comet Lovejoy on TV but the BBC has an article
"A comet's close encounter with the Sun has given scientists a look at a solar region that has never been visited by spacecraft.
In 2011, comet Lovejoy hurtled deep into the Sun's violent atmosphere - an area called the solar corona.
Telescope images have revealed how the comet's tail was pulled about by an intense magnetic field, allowing scientists to characterise this force for the first time.
The study is published in Science...."
