Detecting clouds of 'pig tail' on the galaxy

The group of Japanese scientists at Keio University and the National Astronomical Observatory on September 4 published a photo of gas clouds forming very beautiful swirls in the center of the galaxy , roughly the way of the Sun. 30,000 light years.

Images of molecular clouds resemble "pig tails" due to the
Japanese scientist caught in the center of the galaxy.

With the shape of this molecular cloud, scientists call it the "pig tail." They used electromagnetic telescopes at the Nobeyama Space Observatory in Nagano prefecture to capture the image of the crowd. This molecular cloud.

The length of the whole cloud is up to 60-70 light years, while the ring diameter of the 'pig tail' curves about 50 light years. The majority of the composition of the 'pig tail' is hydrogen with the same amount of tens of thousands of Suns combined.

It is likely that this "pig tail" cloud is the product of a mixture of two large gas clouds rolled together in the center of the galaxy. According to scientists, this spiral may have been around 1.8 million years ago.
