An astronaut took this photograph of the Aurora Australis in August 2017. At the time, the International Space Station was moving over the southern Indian Ocean towards the Great Australian Bight and Melbourne, Australia.
The James Webb telescope has revealed a jet stream on Jupiter that is is more powerful than a category-five hurricane. It’s also estimated to be 3,000 miles (4,800 kilometers) wide and was traveling at 320 miles per hour (515 kilometers per hour).
And to top it off, JWST also captured evidence of auroras on Jupiter.
For those of you interested in aurora-watching: There've been a couple of CMEs in the last day or so, and the wavefront of one of them is in the process of arriving in Earth orbit this evening. The larger one will be arriving sometime tomorrow.
There's no telling for sure whether significant auroral activity might be happening where you are... but if you want to be able to make an educated guess, the link above is for you. The maps there will give you 30-minute warning of whether anything's incoming that's likely to be visible.
The aurora borealis lights up the night sky behind Iceland's iconic Kirkjufell volcano. Auroras are caused when charged particles from the sun collide with gases in Earth's atmosphere. The color signifies the layer of Earth's atmosphere where these interactions are happening.
