Why is it so light outside tonight

On these December evenings, turn toward the northern sky and see its famous constellation Cassiopeia the Queen. At mid-month, Cassiopeia swings directly over Polaris, the North Star, at around 7:p. The rock-comet itself is closest to Earth December 16.


This collection of lunar plains – the solidified remnants of ancient seas of molten magma – actually makes the near side of the moon reflect less light than the far side does, which lacks the maria. So when the atmosphere is thicker, it scatters more blue light but retains that reddish tint which can give the moon an orangey hue.

Picture, then, a “supermoon” shining outside their window.

If the light kept just one or two patients awake, it could easily lead to others being disturbed.

Sky Tonight Credits: Sky Tonight . The peak time for the shower are the nights of the 13th and 14th of the month, so you may notice more meteors than usual around this time, but the waning last quarter Moon could drown out the fainter meteors . A “BEAVER Moon” will light up the sky tonight. The phenomenon, the second supermoon of the year, was so named because traditionally it was the time when fur hunters set beaver traps. All about the Beaver Moon appearing in the skies tonight. So there is no long period of darkness between sunset and moonrise.


Tonight – or any December evening – find the famous constellations Orion the Hunter, and see the Milky Way running behind it. Orion is bright and can be seen from inside smaller cities. Skyglow (or sky glow) is the diffuse luminance of the night sky, apart from discrete light sources such as the Moon and visible individual stars. While usually referring to sky luminance arising from artificial lighting, skyglow may also involve any nighttime sources of diffuse light , . For example, if you go outside tonight at 7:and tomorrow at 11:0 you would see the moon in two very different places in the sky.


This particular moon tends to appear massive and often . Sirius is the nearest star to the sun that is visible from Los Angeles. The waning moon makes its appearance nearly an hour later from one night to the next through the 13th. Its phase changes from gibbous to last quarter on the night of the 9th, and then it is crescent on the following nights. So get ready for some fist-shaking at the moon tonight ! You might see some bright Geminids flying in the moonlight! The bright waning gibbous moon might obstruct your view of Orion and the stars tonight , but the moon will rise approximately an hour later with each passing night.


Earth, Space, Human Worl Tonight. Light pollution washes out the night sky, dramatically reducing the number of fainter meteors you will see. Focus on stars Betelgeuse and Rigel. We love your photos and welcome your news tips.


Why is Mars so faint now, while Venus is so bright ? Venus, the larger of these two planets, is always bright in our sky, in part because of its nearness to us, but also because its surface is covered with highly reflective clouds. Mars lacks those thick clouds, and is far across the solar system from Earth now. These images of Mars, Jupiter, and Saturn (top to bottom) were captured by Griffith Observatory Telescope Demonstrator Blake Estes on. Before dawn is far advance the bright planets Jupiter, in the constellation Libra the Scales, and Mars, that moves from Virgo the Maiden into Libra on the 21st, are .
