Really – if a negative. Unless the Grauniadh has changed the photo, the one I saw looked like a cloud against a sunset/rise sky.
Seriously?
And yet the Guardian, BBC, and photos here, all show a comet looking exactly „like that“. As indeed is my recollection of Hale-Bopp from the 1990s. So while <i>some</i> comets don’t „look like that“, clearly some do.
