No vaccines exist that protect people against infections by coronaviruses, including SARS-CoV-2, which causes COVID-19, or the ones that cause SARS and MERS. As COVID-19 continues to wreak havoc, many labs around the world have developed a laser-like focus on understanding the virus and finding the best strategy for stopping it. Researchers now suggest that the approach they took for a MERS virus vaccine may also work against SARS-CoV-2.

New analysis of data from NASA's Cassini spacecraft found that electric currents, triggered by interactions between solar winds and charged particles from Saturn's moons, spark the auroras and heat the planet's upper atmosphere.

Just like we orbit the sun and the moon orbits us, the Milky Way has satellite galaxies with their own satellites. Drawing from data on those galactic neighbors, a new model suggests the Milky Way should have an additional 100 or so very faint satellite galaxies awaiting discovery.
