For 15 years, we’ve been trying to figure out what created them. We thought we had the answer. And now new research has just complicated everything. These are the Fermi Bubbles found by the Fermi gamma ray telescope back in 2010. Two bubbles of gas so hot they’re giving out gamma ray light a billion times more energetic than light we see with our eyes. And for the past 15 years us astrophysicists have been trying to figure out what these bubbles are and what formed them? And at the start of the 2020s we thought there was finally enough pieces of evidence that had come together to solve the Fermi bubble mystery, but then at the end of 2025, a new research paper was published that has put the cat amongst the pigeons once again...
