In 2019, researchers captured the first image of a black hole. They were able to do this by having all the major radio telescopes on Earth act together to simulate a radio telescope that was the size of Earth. Before this, we could only see indirect evidence of the existence of black holes. This particular […] Continue reading

Kepler Supernova

The image above is of Kepler’s Supernova, which Johannes Kepler is credited with discovering with his description of the stellar object in his De Stella Nova. As stars progress through their main sequence lifetime and beyond and use up more of their hydrogen in nuclear fusion, they can fuse heavier and heavier elements. More massive […] Continue reading
