PSR J0357+3205 in 60 Seconds
Narrator (April Hobart, CXC): A 
spinning neutron star is tied to a mysterious
tail, or is it? Astronomers using NASA's Chandra
X-ray Observatory have found a long, X-ray
bright tail streaming away from the pulsar
known as PSR J0357. The tail appears to stretch
for over 4 light years from behind the pulsar,
which would make it the longest one ever seen
trailing behind this type of pulsar. However,
as is often the case in astronomy, things
are not quite so simple. The amount of energy
being lost from the pulsar doesn't seem to
account for all of the material seen in the
tail. Also, the brightest portion of the tail
is not actually near the pulsar, which scientists
would expect. So scientists plan on looking
at PSR J0357 more in the future with Chandra
and other telescopes, and hope that even more
data will help them pin down what is happening
in this intriguing object.
