APOD: Milky Way Auroral Flower (2022 Oct 18)

Post by APOD Robot » Tue Oct 18, 2022 4:09 am

Image Milky Way Auroral Flower

Explanation: Could the stem of our Milky Way bloom into an auroral flower? No, not really, even though it may appear that way in today’s featured all-sky image. On the left, the central plane of our home galaxy extends from the horizon past the middle of the sky. On the right, an auroral oval also extends from the sky's center -- but is dominated by bright green-glowing oxygen. The two are not physically connected, because the aurora is relatively nearby, with the higher red parts occurring in Earth's atmosphere only about 1000 kilometers high. In contrast, an average distance to the stars and nebulas we see in the Milky Way more like 1000 light-years away - 10 trillion times further. The featured image composite was taken in early October across a small lake in Abisko, northern Sweden. As our Sun's magnetic field evolves into the active part of its 11-year cycle, auroras near both of Earth's poles are sure to become more frequent.

At the reflecting lake level it appears as though an owl has come face-to-face with its short ionic lifespan.

Sorry - not sure what you're referring to. I'm sure it's a brilliant observation but it apparently just whooshed over my head as those have been known to do.
