After all, in recent years we have seen many types of solar systems containing the thousands of exoplanets that have been discovered, and realized that most of them are very different in format from our own solar system. Generalizing from our own solar system turned out to be very wrong. Still, as far as we can tell, light and heat have been of central importance. The Earth would not have life on it if the Sun had not brought the surface temperature of our planet above the freezing point of water, but well below the boiling point.

The entire 200-ton (≈180,000 kg) central structure and observing platform is suspended near the top in a 10-ton (9000 kg) tank of mercury.
Note that the entire telescope is suspended on a trough of liquid mercury (labelled Float in the diagram) in order to reduce vibrations and so the central structure can turn to keep up with the image rotation provided by the use of a heliostat, and that the observer stands on a platform attached at ground level, about two-thirds of the way from the base up the tower (labelled 40 Foot Dia. Table), in order to have access to the focused image. This facility is part of the National Solar Observatory, which also operates the McMath-Pierce Solar Telescope – the largest solar telescope in the world, until the size is superseded 15 From sun Turret 136 Feet above ground Azimuth mirror (44 in.
