Remember Comet Atlas, and how the superstitious thought comets brought doom upon all who saw them?
I guess we stared at it a little bit too hard:
As it loses coherence.
Source: The Astronomer’s TelegramComet ATLAS (C/2019 Y4), what are you doing? New data from astronomers around the world show that the once-promising comet is beginning to fade. For Karl Battams of the Naval Research Lab in Washington DC, it could be a classic case of “I told you so.”“Quoting myself from March 15th,” says Battams, “‘I wouldn’t be surprised to see Comet ATLAS start to fade rapidly and possibly even disintegrate before reaching the sun.’ I very much hope I’m wrong, but Comet Elenin did something similar several years ago, holding lots of promise and then just… fizzling.” …
On April 6th, astronomers Quanzhi Ye of the University of Maryland) and Qicheng Zhang of Caltech reported new images of Comet ATLAS, in which the comet’s core appears to be elongating–“as would be expected from a major disruption of the nucleus,” they wrote in an Astronomical Telegram. …
Recent measurements of the comet’s position also point to trouble. Battams explains: “The comet’s orbit is now being influenced by ‘non-gravitational’ forces. These forces are the result of gases lifting off the comet nucleus and causing the nucleus to move very slightly in the opposite direction–sort of like a jet engine. Most active comets experience this to some degree, but ATLAS’s non-gravitational forces have kicked in very abruptly and are quite strong. This supports a narrative of a small nucleus being pushed very strongly by extreme outgassing, possibly along with fragmentation.” [SpaceWeather.com]
The doom redounded on it, and that was all. So much for any fun for me!
