Galaxies have magnetic fields, too! Images here
Until recently, magnetic fields in the outskirts of galaxies were too faint to be detected. Although it’s still not clear what causes them or how they’re maintained, astronomers have started to create images of their observations of galaxies’ magnetic fields producing beautiful aurora-like effects. See them here. Source: https://earthsky.org/space/images-of-magnetic-fields-in-galaxies…
The myths behind the southern and northern lights
For millennia, humans have viewed the northern and southern lights – aurora borealis and aurora australis – and created myths and folklore to explain the dancing lights they saw in the sky. Source: https://earthsky.org/human-world/legends-folklore-myths-northern-southern-lights-auroras…
Photos of fiery Mars, nearly at its best in 2 years
Photos from the EarthSky community of the bright planet Mars, now nearly at its best. Earth will pass between Mars and the sun – bringing the planet to a once-in-two-years opposition – on October 13, 2020. Source: https://earthsky.org/astronomy-essentials/photos-mars-at-its-best-sep-oct-2020…
What is pareidolia?
Seeing a dog in a patch of clouds, or a face in the moon, are examples of what’s called pareidolia. Look here for photos to test your own ability to see things that aren’t there. Source: https://earthsky.org/human-world/seeing-things-that-arent-there…
Citizen scientists identify new form of northern lights
Space researchers and amateur photographers in Finland have identified a new type of aurora, or northern lights. They call them “dunes.” Read more and see a video. Source: https://earthsky.org/earth/citizen-scientists-new-aurora-northern-lights-dunes…
New Type of Aurora Called ‘The Dunes’ Documented
davidwr writes: Remember the aurora-that-wasn’t called STEVE from last April? Well, amateur stargazers in Finland are at it again. This time it’s for a new kind of aurora dubbed “the dunes.” These new aurora are thought to be an example of a “mesosphereic bore” in which oxygen is exited by the solar wind or possibly gravity waves. The original paper can…
