A team of researchers led by Miyuki Kaneko at Japan's Keio University used data from the James Clerk Maxwell Telescope (kính viễn vọng) to identify an unusual cloud of gas about 27,000 light-years away in the constellation (chòm sao) Sagittarius.

They combined this with information from the National Astronomical Observatory (đài quan sát) of Japan's Nobeyama 45-m Radio Telescope to discover the object, which has been dubbed a 'Space Tadpole (con nòng nọc)'.

The curved 'Tadpole' shape of the molecular gas cloud strongly suggests that it is being stretched as it orbits around a massive compact object.

At the centre of the Tadpole's orbit, there are no bright objects which could be massive enough to gravitationally hold the Tadpole.
