A heliostat is a device that uses mirrors to track the movement of the sun and reflect sunlight onto a specific target, such as a solar panel or a building. It is commonly used in solar energy systems to maximize the amount of sunlight that can be captured and converted into usable energy.
Usually it's simply called a "solar telescope, but there are other names such as "helioscope" (specialising in sunspot observation).
By letter (or personal messenger)by the help of doves,pigeons,and faithful owls n eagles, by foot, horse, or ship. There was also semaphore, helioscope (flashing mirrors), and smoke signals for relatively short, important messages.
The fastest method of DNA sequencing as of Jul, 2008 is a tech called HelioScope(tm) that claims to be able to sequence 1.2 Billion bp in 1 hour, using advanced fluorescent microscopy and a suitable marker system. The sequencer costs a scratch over 1 million dollars US, and is probably going to redefine genomics as we know it.
Because they are highly luminous, stars may be observed directly in visible light frequencies. One example is the Sun, which is close to Earth and can be examined easily in the daytime, for example with a helioscope.
