2 giant blobs at the core of our galaxy are spewing radiation. Scientists don't know how they got there.

7 years ago
In 2010, astronomers working with the Fermi Gamma-ray Space Telescope announced the discovery of two giant blobs. These blobs were centered on the core of the Milky Way galaxy, but they extended above and below the plane of our galactic home for over 25,000 light-years. Their origins are still a mystery, but however they got there, they are emitting copious amounts of high-energy radiation.
