description Edward Maunder Overview

Edward Walter Maunder was a British astronomer whose work at the Royal Observatory, Greenwich, concentrated on sunspots and other solar phenomena. He documented a prolonged scarcity of observed sunspots between about 1645 and 1715, a period later named the Maunder Minimum. His research remains relevant to the historical study of solar activity and its possible relationship to conditions on Earth.

help Edward Maunder FAQ

What is the Maunder Minimum?

It's the period between roughly 1645 and 1715 when astronomers documented an unusually low number of sunspots, based on the historical records Edward Maunder compiled at Greenwich. The interval coincided with some of the coldest decades of the so-called Little Ice Age, though the exact link remains debated.

Where did Edward Maunder work as an astronomer?

He spent his career at the Royal Observatory, Greenwich, where his duties centered on observing and photographing sunspots and other solar phenomena. It was this systematic solar record-keeping that led him to identify the long sunspot drought now bearing his name.

Did Edward Maunder believe in the canals of Mars?

No — he was an early skeptic, arguing that the 'canals' reported by observers like Percival Lowell were optical illusions produced by the human eye connecting faint, scattered markings. His position was later vindicated by spacecraft imaging in the 1960s.

Who was Annie Maunder, and what was her connection to Edward?

Annie Scott Dill Maunder was his wife and scientific collaborator, a talented astronomer who photographed solar eclipses and co-founded the British Astronomical Association with him in 1890. Both Maunders are commemorated with craters named after them — on the Moon and on Mars.
