EVSN - Discovery of Twin Supernovae Could Open Up Dark Energy Experiments

The 365 Days of Astronomy

From May 11, 2021.

SNFactory researchers found that among about 50 supernovae, many had nearly identical spectra, paving the way for making more accurate distance calculations. These calculations, in turn, open up the possibility of using supernovae to better search for dark energy. Plus, OSIRIS-REx, Voyager I, planetary formation, and volcanoes on Mars.
