Quasars
5th October 2010Astronomy
Quasars (QUAsi-Stellar Radio Source) is a very energetic and distant galaxy with an active galactic nucleus. They are the most luminous objects in the universe.
Pulsars
5th October 2010Astronomy
Pulsars are highly magnetised, 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

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.

Binoculars play a big part in astronomy for beginners and experienced amateurs alike. They are generally cheaper and much easier to use than telescopes and offer a broad range of what's on offer in the night's sky.
The Danjon Scale
2nd June 2010Astronomy
The Danjon Scale of Lunar Eclipse Brightness is a five-point scale useful for measuring the appearance and luminosity of the Moon during a lunar eclipse. It was proposed by André-Louis Danjon when he was measuring the Earthshine on the Moon.
