In December 2019, researchers at the Zwicky Transient Facility (ZTF) identified the sudden brightening of the nucleus within galaxy SDSS J133519.91+072807.4 (hereafter Ansky).
The Friedmann equation, derived from general relativity, governs the expansion of spacetime. However, it was found incompatible with observations, notably the universe’s accelerating expansion.
I have been fascinated by the night sky since I ‘discovered’ Saturn with my 60mm refractor at the age of 10. An APOD-winning astrophotographer, I have been published in Sky & Telescope, Astronomy Magazine, and Space.com. As a NASA Solar System Ambassador, I have conducted thousands of public outreach programs and am a registered cruise ship speaker on astronomy and space science, as well as a Director of the Phoenix Astronomical Society. I frequently post astrophotography images, news, and tutorials on social media. My solar imaging and videos are particularly popular, and I have conducted extensive research on solar cameras and solar image processing techniques.
