...already long list of odds against the experiment, Astronomer Earl C. Slipher of Lowell Observatory had added another: his belief that it had been snowing on Mars last week...
Earl Carl Slipher of Lowell Observatory (Flagstaff, Ariz.) has spent more time looking at Mars than any other living astronomer. Some years ago he made photographs showing that there are clouds and storms in the atmosphere of Mars, mostly in the neighborhood of the Martian equator. These are thickest in the early Martian morning, quickly vanish as the sun climbs...
Since there is a better view of Mars this time from the Earth's southern hemisphere than from the northern, Dr. Slipher was last week posted at Harvard's observatory near Bloemfontein in South Africa. He discovered that Solis Lacus, a dark spot on Mars as big as the U. S. and located near the Martian south pole, had assumed a shape never before seen, or at least not in the last half-century. This change of shape, reasoned Old Marster Slipher, could be plausibly ascribed to the growth of fresh vegetation...
...light from the sun which reaches Earth and is reflected back to the moon. By spectroscopic analysis of this "earthshine" and by inferring additional details from the known phenomena of optics, astronomers can form a plausible idea of how Earth looks from other planets. Last week Director Vesto Melvin Slipher of Lowell Observatory (Flagstaff, Ariz.) told how Earth must look to Mars. The Martian astronomer sees a planet bluer than Venus and bigger. If he looks sharp he can see the polar caps shrinking and spreading with the change of seasons. Through rifts in the cloud veil, he discerns great...
...shells of tremendously hot gas at 1,000,000 m.p.h. By last week it had jumped 13 magnitudes to the first, acquired a name, Nova Herculis 1934. Its radiation had increased 200,000 times; it was among the twelve brightest stars in the sky. Directors Vesto Melvin Slipher of Lowell Ob servatory (Flagstaff, Ariz.) and Harlow Shapley of Harvard Observatory obtained remarkable spectra, said the star might be the most important stellar outburst ever witnessed...
