Comets, Asteroids, Meteors and Dust


Hale-Bopp CometComets are very special phenomena in our Solar System. People have always been fascinated by their sudden and brief appearance in the dark sky, only to last for some weeks or months at the very most.

They are also a very peculiar spectacle. Although they often do not glitter spectacularly, they can have a long tail that lights up a large part of the sky, whenever they are observed from a dark place with few light pollution.

BRAMSA meteoroid is a particle of debris in the Solar System. The visible phenomenon due to the fly of a meteoroid through the atmosphere is called a meteor. If a meteor reaches the ground, then it is called a meteorite.

BRAMS (Belgian RAdio Meteor Stations) is a set of radio receiving stations using forward scattering techniques to study the meteoroid population. The project is coordinated by the Royal Belgian Institute for Space Aeronomy (BIRA-IASB), in the frame of the Solar-terrestrial Centre of Excellence (STCE).
