A huge coronal hole
that is hundred times bigger than the earth is spotted in the sun by NASA
camera aboard NASA's Solar
Dynamics Observatory on Jan. 1, 2015.
The irregularly shaped hole spans about 400,000 kilometers
(250,000 miles) at its widest point, said
Dr. C. Alex Young, associate director for science for the heliophysics division
at the space agency's Goddard facility in Greenbelt, Maryland. Its total surface
area is about 410 times that of the Earth, he said (see below for size
comparison).
This is not the first time a hole was spotted in the sun but
never of this size and in this sense.
According to NASA in Huffington
Post, Coronal holes were first
seen in photos taken by NASA astronauts in the 1970s. They aren't holes in the
usual sense. Rather, they're colder, cooler
regions where the sun's magnetic field reaches
out into space. The holes can remain visible for five years or longer.
Americans however took to the social media commenting on this
comically though.
A Facebook user wrote:
“I blame
Obama.”
Another
pinned it on George W. Bush, “Come on, everyone knows it is Bush's fault :)”
