Mon, 12 Nov 2007 02:59:03 GMT

The apparent magnitude which a star would have if it were observed from a standard distance of 10 parsecs.

apparent magnitude

Mon, 12 Nov 2007 02:58:37 GMT

The apparent brightness of a celestial body; the lower the magnitude, the brighter the object.

azimuth

Angular measure around the horizon or parallel to it in the sky.

astronomical unit

Mon, 12 Nov 2007 02:10:38 GMT

Literally a "bright spot." It is used in planetary nomenclature for naming certain surface features of planets and moons, and is also a type of surface phenomenon on the Sun.

envelopes

Mon, 12 Nov 2007 01:43:06 GMT

eclipses

Mon, 12 Nov 2007 01:36:28 GMT

Occurs when one celestial object moves into the shadow of another.

NT lunar eclipses
NT solar eclipses

bolides

Mon, 12 Nov 2007 01:35:05 GMT

An exceptionally bright fireball, particularly one that explodes (sometimes called a detonating fireball).

accretion disks

Mon, 12 Nov 2007 01:30:39 GMT

An accretion disc (or accretion disk) is a structure formed by diffuse material in orbital motion around a central body. The central body is typically either a young star, a protostar, a white dwarfs, a neutron star, or a black hole.

BT eclipses

heliacal rising

Thu, 08 Nov 2007 12:45:00 GMT

Occurs when a star (or other body such as the moon or a planet) first becomes visible above the eastern horizon at dawn, after a period when it was hidden below the horizon or when it was just above the horizon but hidden by the brightness of the sun.

grazing occultations

Thu, 08 Nov 2007 12:41:00 GMT

A special type of lunar occultation that occurs within a mile or two of the edge of an occultation's predicted path, referred to as its northern or southern limit. Within that narrow zone, an observer may see the star intermittently disappearing and reappearing as the irregular limb of the moon moves past the star, creating what is known as a grazing occultation. From an observational and scientific standpoint, these "grazes" are the most dynamic and interesting of lunar occultation.

electromagnetic radiation

Thu, 08 Nov 2007 12:38:00 GMT

NT gamma rays

gamma rays

Thu, 08 Nov 2007 12:37:00 GMT

Forms of electromagnetic radiation (EMR) or light emissions of a specific frequency produced from sub-atomic particle interaction, such as electron-positron annihilation and radioactive decay; most are generated from nuclear reactions occurring within the interstellar medium of space.
