    • Some scientists in China found a stellar black hole (black hole formed by a collapsing star) so large that science itself cannot explain it. Its mass is 70 times greater than our sun and scientists didn’t think a stellar black hole could exceed 20 times the mass of our sun. The reason being due to matter that is supposed to be lost from winds formed by the star collapsing. Below is a key quote from the article: 

      "Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution," project leader Liu Jifeng said. "LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation."

      I think it’s always exciting to discover new things that push the limits or challenge our very understanding how things are supposed to work. Especially in the realms of outer space. Based on my limited time studying black holes, my understanding is there is so much more that we don’t know about them than what we do know. Both crazy and exciting to think about! 

    • This is wild to imagine and the mass calculation must have had the scientists freaking out! I remember when this headline came through earlier this year: "Scientists Photograph a Black Hole for the 1st Time" and actually, the image didn't disappoint!

      The Event Horizon Telescope, a planet-scale array of eight ground-based radio telescopes forged through international collaboration, captured this image of the supermassive black hole in the center of the galaxy M87 and its shadow.(Image: © EHT Collaboration).
