Polar stratospheric clouds!
The best Polar stratospheric cloud display in decades is currently happening. From Spaceweather.com...
Polar stratospheric clouds are rare. Normally, the stratosphere has no clouds at all. A few times each winter, however, icy clouds form when the temperature in the stratosphere drops below -85C. Such staggeringly-low temperatures are required to help sparse water molecules stick together. This winter, the clouds have been appearing daily since late December, a sign of unusually cold conditions in the stratosphere.
Stratospheric clouds are widely regarded as the most beautiful clouds on Earth. Because of their intense colors (caused by high-altitude sunlight hitting tiny ice crystals), novice sky watchers sometimes mistake the clouds for auroras.

Starlink photobombs a meteor shower...
The Global Meteor Network camera captured an outburst of alpha Monocerotid meteors on Nov. 22nd. Earth was passing through a filament of comet dust, prompting a flurry of meteors to emerge from the constellation Monoceros (the Unicorn). However Starlink satellites showed up and photobombed the meteor shower!

The Transit of Mercury seen from Space
"More than 22,000 miles above Earth's surface, NASA's Solar Dynamics Observatory (SDO) recorded an incredible movie of the transit. This movie is unlike any recorded on Earth. High above our planet's atmosphere, extreme ultraviolet telescopes onboard SDO were able to see Mercury making first contact with the sun's outer atmosphere, the corona. The wavelengths required to gain this view are blocked by air and only visible from space."

A moment to remember
Today is Remembrance Day here in Canada, and in many other countries around the world.
Every year on November 11, Canadians pause to remember the men and women who have served, and continue to serve our country during times of war, conflict and peace. We honour those who fought for Canada in the First World War (1914-1918), the Second World War (1939-1945), and the Korean War (1950-1953), as well as all those who have served since then.
Each year, millions of Canadians wear poppies as a symbol that they will never forget, and to honour those who have paid the ultimate sacrifice.
