Astronomical Objects

Astronomical objects or celestial objects are naturally occurring physical entities, associations or structures that current science has demonstrated to exist in the observable universe. Astronomical (or celestial) body refers to a single, cohesive structure that is bound together by gravity and include asteroids, moons, planets and the stars. Astronomical objects are gravitationally bound structures that are associated with a position in space, but may consist of multiple independent astronomical bodies or objects and can include star clusters, nebulae or entire galaxies.

The Kuiper belt is an area of the solar system extending from the orbit of Neptune (at 30 AU) to 50 AU from the Sun. The objects within the Kuiper Belt together with the members of the scattered disk extending beyond, are collectively referred to as trans-Neptunian objects.

Pulsars are highly magnetized, rotating neutron stars that emit a beam of electromagnetic radiation. The radiation can only be observed when the beam of emission is pointing towards the Earth. This is called the lighthouse effect and gives rise to the pulsed nature that gives pulsars their name.
Supernova and Supernovae
05/10/2010Astronomical Objects
Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months.
What is a Galaxy?

Billions of galaxies populate our universe, each one a vast group of stars that exist together in space. We live in one of these galaxies called the Milky Way, named after the path of milky light that it's stars make across the Earth's sky.
Types of Nebula and Nebulae

A Nebula (or Nebulae plural) is a mixture of interstellar dust, hydrogen gas, helium gas and plasma. The name comes from the latin meaning cloud.
Asteroids, Meteors and Comets

Asteroids, Meteors and Comets are cosmic visitors from the far reaches of space. Commonly grouped together as they are basically the same thing - rock and ice from deep space.
