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.

On March 5, 2021, three separate, large earthquakes occurred within hours of each other near New Zealand, and all three produced a tsunami. The resulting changes in wave height were recorded with special buoys. Plus, a radar blackout at Mars, a giant planet growing, small galaxies in the early Universe, and what even is a day?

Fourteen Gamma Ray Sources Are Possibly Stars Made of Antimatter

In another first for NASA’s Perseverance rover, a cube-shaped instrument called MOXIE, or Mars Oxygen In-Situ Resource Utilization Experiment, has successfully converted some of Mars’ atmospheric carbon dioxide into oxygen. Plus, a wild roundup of stories including exoplanets, sky maps, fast radio bursts, meteorites, and the problem with symmetry.
