On a sunny day with a blue sky filled with clouds, try stepping out into your garden or go for a walk. Now look at the clouds above. Use your imagination and try to make out as many interesting patterns or shapes that you can see — like a sky pictionary! Strange-shaped clouds of gas also exist beyond our planet, farther out in space.
Using data from the James Clerk Maxwell Telescope and NAOJ’s Nobeyama 45-m Radio Telescope, a team of researchers from the Keio University in Japan identified an unusual cloud of gas. The cloud is nicknamed “Tadpole” due to its curved shape. Tadpole is located at about 27,000 light-years away from Earth, in the Sagittarius constellation.
The research team suspects there is a massive, yet small object behind the curved shape of the Tadpole. This is because the cloud appears to be stretched as if it were being pulled by something massive while moving around it, due to gravity. Just like when you drop a rock into a pantyhose. Researchers then began to look for bright massive objects at the center of Tadpole’s orbit, like the Sun at the center of our Solar System. But, very much to their surprise, they could not find any!
