He was the first to detect the comet of 1815 (Comet Olbers, period 72.7 years).
Considering their orbits and those of the other asteroids then known, Olbers concluded that they are fragments of a disrupted planet that had formerly revolved around the sun.
He is best remembered for Olbers' paradox: “Why is the sky dark at night?” Assuming that space is infinite and filled with stars, he suggested, the entire sky should be as bright as the surface of the sun.

 Olbers' paradox   (Site not responding. Last check: 2007-11-07)
Olbers' paradox, described by the German astronomer Heinrich Wilhelm Olbers in 1823 and earlier by Johannes Kepler in 1610 and Halley and Cheseaux in the 18th century, is the paradoxical statement that in a static infinite universe the night sky should be bright.
If the universe is assumed to be infinite, containing an infinite number of uniformly distributed luminous stars, then every line of sight should terminate eventually on the surface of a star.
It is currently not known whether this is true or not, although recent satellite studies have found the cosmic microwave background radiation is isotropic to 1 part in 10000.

In March 1802 he discovered Pallas and became convinced that asteroids are the broken-up remnants of a medium-sized planet that once orbited in the asteroid belt region.
In 1811 Olbers formed the theory that the tail of a comet always points away from the Sun because of pressure from the Sun's radiation.

 Olbers, Heinrich Wilhelm Matthäus (1758-1840)
The method he developed to figure out the orbit of a comet that he discovered in 1786 became standard in the nineteenth century.
William Olbers was also a supporter of pluralism and of the increasingly contentious idea that the Moon was inhabited by intelligent beings (see Moon, life on).
In the same paper in which he presented his famous paradox, he wrote that it is "most highly probable" that "all of infinite space is filled with suns and their retinues of planets and comets."

If the Universe were infinitely old, infinite in extent, and filled with stars, then every direction you looked would eventually end on the surface of a star, and the whole sky would be as bright as the surface of the Sun.
This is known as Olbers' Paradox after Heinrich Wilhelm Olbers (1757--1840) who wrote about it in 1823--1826 (though it had been discussed earlier).
The resolution of Olbers' paradox comes by recognizing that the Universe is not infinitely old and it is expanding.

He suggested a theory for why the tails of comets point away from the sun and discovered the second and third known asteroids—Pallas (1802) and Vesta (1807).
Astronomers at the time assumed an infinite universe in which the night sky should be covered with stars, and his formulation of why, in that case, the night sky is dark became known as Olbers' Paradox.
