ARLA/CLUSTER: Tudo indica que a maior parte do Cometa ISON se desintegrou.

[João Costa > CT1FBF]

 *CANCEL THE EULOGY: *Comet ISON flew through the sun's atmosphere on Nov.
28th and the encounter did not go well for the icy comet. Just before
perihelion (closest approach to the sun) the comet rapidly faded and
appeared to disintegrate. This prompted reports of ISON's demise. However,
a fraction of the comet has survived. Click on the image below to see what
emerged from Comet ISON's brush with solar fire:

In the movie<http://spaceweather.com/images2013/28nov13/rip_anim5.gif?PHPSESSID=2f5i60j78dfukcgsqmhqek16g7>,
Comet ISON seems to be falling apart as it approaches the sun. Indeed,
researchers working with NASA's Solar Dynamics Observatory said they saw
nothing along the track that ISON was expected to follow through the sun's
atmosphere. Nevertheless, something has
emerged<http://spaceweather.com/images2013/28nov13/remains_strip.gif?PHPSESSID=2f5i60j78dfukcgsqmhqek16g7>.
Whether this is a small scorched fragment of Comet ISON's nucleus or
perhaps a "headless comet"--a stream of debris marking the remains of the
comet's disintegrated core--remains to be seen.
