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…

Find the Geminids’ radiant point
Why is the Geminid meteor shower best around 2 a.m.? It’s because that’s when the shower’s radiant point – near the bright star Castor in the constellation Gemini – is highest in the sky. Source: https://earthsky.org/astronomy-essentials/radiant-point-for-geminid-meteor-shower…
Scientists Produce Rare Diamonds In Minutes At Room Temperature
Iwastheone writes: While traditional diamonds are formed over billions of years deep in the Earth where extreme pressures and temperatures provide just the right conditions to crystalize carbon, scientists are working on more expedient ways of forging the precious stones. An international team of researchers has succeeded in whittling this process down to mere minutes, demonstrating a new technique where they…
Leonid meteor shower is building to a peak
The peak of the Leonids is likely to be before sunup on November 17, 2020. But people already catching some Leonids. Keep an eye out this weekend. Source: https://earthsky.org/tonight/leonid-meteors-before-dawn-november-17…
Why Arctic sea ice has stalled, and what it means for the rest of the world
In the next few decades, scientists expect we’ll see an ice-free Arctic Ocean throughout the summer. That prospect got much closer in 2020, due in part to the exceptional summer heatwave that roiled the Russian Arctic. Source: https://earthsky.org/earth/why-arctic-winter-sea-ice-stalled-2020…
