Comet
Ison likely didn't survive its graze past the sun early this
afternoon, astronomers say.
"It's
not looking good for Ison in my opinion," said Phil
Plait, an astronomer who writes for Slate's Bad Astronomy blog,
during a Google Hangout organized by NASA Thursday.
"That's
kind of my assessment too," agreed Karl Battams, an
astrophysicist at the Naval Research Laboratory in Washington, D.C.,
who runs the NASA-funded Sungrazing Comets Project.
Images
from NASA's SOHO spacecraft at 1:12 p.m. ET showed long tails that
appeared as though they could be fading toward the sun, and the head
of the comet was no longer visible.
By
2 p.m. ET, images from the Solar Dynamics Observatory spacecraft did
not show the comet at all, to the surprise of Dean Pasnell, project
scientist for SDO, who said the rocky material from the comet
wouldn't be expected to evaporate that quickly.
