Astronomers have discovered what they think could be a black hole roaming the Milky Way all by its lonesome.

Why it matters: The discovery of this possible black hole will allow researchers to pin down exactly how many of these objects may exist out there in our galaxy and how far away they might be, helping illuminate the nature and evolution of these mysterious objects a little bit more.

What's happening: The Hubble Space Telescope was able to measure the object — which is about 5,000 light-years from Earth — during observations that took place over the course of six years.

But, but, but: It's possible the object isn't a black hole at all.
