They are not quite stars or quite planets, but something in between, and there could be more than previously thought in our galaxy.

This is assured by a new study published by the scientific journal The Astrophysical Journal, which focuses on a new and “enigmatic” brown dwarf who has been nicknamed “The Accident”, because it was discovered by chance.

Brown dwarfs are objects too small to be stars and too big to be considered planets. They are sometimes called “failed stars“.

“This object defied all of our expectations,” said Davy Kirkpatrick, a co-author of the study and an astrophysicist at the California Institute of Technology (Caltech).
