Dusty sunrises and sunsets over U.S. South
See the layers of dust set against this South Carolina sunset? That dust came from Africa’s Sahara Desert. It traveled across the Atlantic Ocean this month to cause dusty skies across the U.S. south and into Texas. Source: https://earthsky.org/todays-image/photos-saharan-dust-june-2020-florida-texas…
More evidence that Europa’s ocean is habitable
A new study shown by NASA scientists at the Goldschmidt conference this week provides further evidence that Europa’s ocean is habitable and similar to Earth’s oceans. Source: https://earthsky.org/space/europa-ocean-habitable-goldschmidt-conference…
Saharan-fed sunsets in the US

More evidence for watery plumes on Europa
Scientists in Europe have found more yet evidence for water vapor plumes on Jupiter’s ocean moon Europa. Source: https://earthsky.org/space/europa-water-vapor-plumes-galileo…
New simulations indicate that Jupiter’s fourth-largest moon ejects water from its subsurface ocean into space
During a fly-by of Jupiter’s moon Europa twenty years ago, NASA’s space probe Galileo may have witnessed a plume of water. A group of scientists including researchers from the Max Planck Institute for Solar System Research (MPS) in Germany have now found new evidence of this event. In computer simulations they strove to reproduce the data gathered by the onboard particle…
Milky Way could be catapulting stars into its outer halo
Scientists used computer simulations to learn that our Milky Way galaxy may sometimes launch newly forming stars into the space around itself – that is, into the halo of our galaxy – via outflows triggered by supernova explosions.

Will Dragonfly find dust devils on Titan?
Earth and Mars both are known to have swirling dust devils moving along their surfaces. Saturn’s large moon Titan might have them, too, according to a new study. If so, NASA’s planned Dragonfly mission will be able to find them. Source: https://earthsky.org/space/saturn-moon-titan-dust-devils-dragonfly…
Some School Districts Plan To End the Year Early, Call Remote Learning Too Tough
An anonymous reader quotes a report from The Wall Street Journal: Some districts are giving up on remote learning and ending the academic year early, after concluding that it was too cumbersome for teachers, students and parents. Washington, D.C., as well as parts of Georgia, Texas and elsewhere plan to end a week to several weeks early. Schools have struggled to…
Massive protostar keeps growing despite ionization heating by ultraviolet light
A gigantic embryonic star is still getting bigger, even though it propels vast plumes of hot gas away from itself, RIKEN astronomers have found. The discovery could help to solve an enduring mystery about how massive stars grow so large. Source: https://phys.org/news/2020-02-massive-protostar-ionization-ultraviolet.html…
