More Info

Nachtricht is back from an astral journey on the tails of multiple comets, those mostly tiny Solar System bodies made of ice and rock, the nucleus containing frozen water, super cold methane and nitrogen, plus metallic bits of Solar System debris left over from its formation. When heated by the Sun these parts begin to sublimate. The mixture of ice crystals and dust blow away from the comet nucleus to create a double tail, the dust one that we normally see and a plasma one which forms when molecules of gas are excited by interaction with the solar wind. This secondary tail is not normally viewed with the naked eye, but can be imaged.

Comets usually orbit in their origins in the Oort cloud and Kuiper belt in the outer most regions of The Solar System beyond Neptune. The most common of several categories of comet are the periodic and non-periodic, and are these days named after a set of rules that don't always acknowledge directly the astronomer, amateur or professional, who was first to see and record them. Well known comets include the non-periodic Hale Bopp, Hyakutake, McNaught, and Lovejoy which flared brightly in our skies but then disappeared into obscurity. In addition, comet Shoemaker-Levy alarmed us all by its break-up and collision with Jupiter. The famous periodic comet Halley returns to our skies every 76 years, but there are other well-known periodics such as 2P/Encke, and 9P/Tempel, which was visited by the Deep Impact and Stardust probes.

We see comets not only directly, on lucky occasions, but also through such delights as the annual Persiads. These meteors, like some others, are comet tail debris breaking up in our atmosphere to provide what we call shooting stars. The closest point of a comet's orbit to the Sun is called Perihelion, the most distant point Aphelion. Material streaming out from the comet as it approaches the Sun populates the comet's orbit, falling to Earth as meteor showers like the Persiads. Comets break up if they come too close to the Sun or a planet in their orbit. Comet orbits are usually elliptical.

In ancient history comets were often interpreted as sky Gods, rather than the scientific explanation we have today - but then, what do we know? Maybe the scenic excursions of the Nachtricht space craft will open our eyes - or ears - just that little bit more.

Good journeying Earthlings...
