Betelgeuse star dimming puzzle solved by chance with weather satellite

The sudden dimming of Betelgeuse in 2019 has been puzzling astronomers ever since, but now we have nailed down the cause

$Mare Crisium is a large, dark, basaltic plain on the Moon that filled an ancient asteroid impact. Basaltic plains on the Moon were created by early volcanic eruptions. Mare Crisium was flooded with basaltic lava, a dark, runny lava commonly found on Earth. Basaltic plains on the Moon are also known as lunar maria, because of a mistaken belief by early astronomers that these dark areas were oceans ? ?maria? is the Latin word for ?seas.? We now know these spots to be plains of basalt created by early volcanic eruptions, but the nomenclature of ?maria? (plural) or ?mare? (singular) remains. The basalts in Mare Crisium range in age from 2.5 to 3.3 billion years old! These dates come from measuring the radioactive isotope signatures of samples returned from Mare Crisium by the Soviet Luna 24 mission. Along the rim of Mare Crisium lies an outer boundary of wrinkle ridges. Wrinkle ridges are commonly found in places where the surface has contracted. As the surface is compressed, it bends and fractures, and can form complicated patterns of faults and folds.$

Hubble?s view of supernova explosion Cassiopeia A A new image taken with the NASA/ESA Hubble Space Telescope provides a detailed look at the tattered remains of a supernova explosion known as Cassiopeia A (Cas A). It is the youngest known remnant from a supernova explosion in the Milky Way. The new Hubble image shows the complex and intricate structure of the star?s shattered fragments.
