In 1894, Lovell actively engaged in astronomy, realized his youthful dream. In the same year in Flagstaff (Arizona), he founded the observatory, designed specifically for the study of the planets.
Of particular interest Lovell called Mars, the observations which he devoted the most attention. Lovell argued that the observed Mars through a telescope mysterious straight lines — "channels" — are the bands of vegetation along the man-made waterways.
His presentation outlined in the book "Mars as a haven of life" in 1908. Parascientific his theory of the existence of an advanced civilization on Mars was not accepted by his contemporaries.
He spent many years in search of the ninth planet of the solar system — and 14 years after his death Clyde Tombaugh was discovered dwarf planet, called Pluto. The name was not chosen by chance — so that is not a loose mythological series, it also includes the initials of Lovell.
