Objects in the Night Sky

Introduction:

Night sky is a generally used term most often employed to refer to the sky as it is seen at night. The term is usually associated with astronomy, with reference to view of heavenly bodies such as stars, the Moon and planets that become visible on a clear night after the Sun has set. The visibility of space objects in the night sky is affected by light pollution.


Objects seen in Solar System at Night:


The Moon

A source of surprise, romance, and reflection since man stand up and then looked up. The brightest object in the night sky is simply visible with the naked eye, but with a pair of binoculars, much detail is revealed.

The Mars

Mars is a small planet, similar in size to our Moon than to the Earth. It can be easily seen with naked eye in the sky at night.

The Jupiter

Jupiter can be seen at night. Binoculars are all needed to see the largest planet of solar system. The moons are really bright enough to see with the naked eye, but are washed-out from Jupiter’s powerful glare. The binoculars will show them as small stars grouped around the gas giant.

Asteroids

Although too dim for binoculars to pull in under city lights, it is well within their reach from a dark sky when the Moon is out of the way.

Comets

Comets will expand daily, glowing pale yellow and looking in binoculars and telescopes like a circular "gas bubble" surrounded by a green halo. Although the comet has washed out a little in recent days, it is still visible with the naked eye from suburban sites.

Meteors

Several meteors per hour may be seen can be seen during in the night sky with naked eyes.


Galaxies visible at Night:


Andromeda Galaxy

Andromeda is the farthest thing you can see with the naked eye appearing as a faint smudge in the night sky. It makes an outstanding object for binoculars. It’s usually the first thing to locate when we look up at night with a pair of binoculars.

The Milky Way

The flimsy, silvery cloud stretching across the sky on dark, clear nights is our home galaxy: the Milky Way. No part of the sky is more heavily packed with visible stars than the Milky Way, or more pleasantly addictive to behold with binoculars.
