Celestial Objects
Lunar Eclipse
Moon is natural satellite of earth and rotate around the earth ,but it brights when sun'slight incident on it. Lunar eclipse occurs when earth's shadows block the sun 'slight which otherwise reflects off the moon . There are basically three types : partial,total and penumbral with the most dramatic being a total lunar eclipse in which earth shadow completely cover the moon & Read More
Conjuctions
Conjuctions occurs when two objects appear to be close together in sky having either same right ascension or same ecliptic longitude observed from earth
A number of coordinate systems are used in astronomy to define where an object appears in the sky, similar to the latitude and longitude system we use on the Earth. The first, the celestial coordinate system of right ascension and declination, is fixed to certain standard points in the sky and is aligned with the tilt of the Earth.
Another, known as the ecliptic coordinate system, is fixed instead to the orientation of our Solar System within our galaxy and is measured in ecliptic latitude and longitude.& Read More
Transits
when a celestial body passes directly between a larger body and the observer. As viewed from a particular vantage point, the transiting body appears to move across the face of the larger body, covering a small portion of it.In our own Solar System it is possible to view the transit of Mercury or Venus across the face of the Sun & read More
Nebulae
A cloud of gas and dust located between stars and/or surrounding stars. Nebulae are often places where stars form.
The Helix Nebula is a layered and complex cloud of gas expelled and illuminated by the dying star at its center. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries"& read More
Nearby Galaxies
Our planetary system is located in an outer spiral arm of the Milky Way galaxy.although several dozen minor galaxies lie closer to our Milky Way, the Andromeda galaxy is the closest large spiral galaxy to ours. Excluding the Large and Small Magellanic Clouds, visible from Earth's Southern Hemisphere, the Andromeda galaxy is the brightest external galaxy .The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula, is a barred spiral galaxy approximately 2.5 million light-years from Earth.
Meteor Showers & Comets
A meteor is a space rock—or meteoroid—that enters Earth's atmosphere. As the space rock falls toward Earth, the resistance—or drag—of the air on the rock makes it extremely hot. What we see is a "shooting star." That bright streak is not actually the rock, but rather the glowing hot air as the hot rock zips through the atmosphere.
When Earth encounters many meteoroids at once, we call it a meteor shower.
