This evening waxing gibbous Moon is making a close pass just above bright star Aldebaran, "the Eye of the Bull" in constellation of Taurus. Every hour the Moon moves about its own diameter eastward (leftward) against the sky, best seen when a bright star or planet is nearby

It seems to me you lived your life like a rover in the wind never fading with the sunset when the dust set in. Your tracks will always fall here, among Mars' reddest hills; your candle's burned out long before your science ever will. . I owe you so much.

Still brutally cold but skies have cleared off for a change. If you're out walking the dog or taking the garbage to the curb, look up! The thick crescent Moon is setting in the WSW. Trailing behind it is the rich swath of bright winter stars known as the "Heavenly G"

Light pillars are perhaps the prettiest form of light pollution, but they are the result of unshielded artifical light shining up into the sky. Ice crystals in the air are responsible for the "pillars", whose colours are due to the type of light source

The new 3D model suggests the two lobes are fairly similar in volume & presumably mass

Elk Island National Park's bison don't hibernate, and neither should you. Explore this wildlife and dark sky preserve just east of Edmonton.

Atmospheric refraction causes not only scintillation (twinkling) of stars, but also produces colour flashes across the spectrum. The brighter the star,& the closer it is to the horizon,the more pronounced the effect. The night sky's brightest star, Sirius, is especially colourful
