Scientific observations from Mount Wilson telescope reveal the Moon's extreme temperatures: hotter than boiling water in sunlight, -254°F in shadow. The Moon lacks atmosphere, unlike Earth. Astronomers study planetary atmospheres for signs of life, possible only on Mars. Upcoming 200-inch telescope may provide evidence of Martian population.

The hottest object anywhere near the Earth is the Moon. Also it is the coldest. Observers using the 100-inch telescope on Mount Wilson have been measuring the moon's temperature for a year.
They report that the parts of the moon on which the sun shines are hotter than boiling water, and the side away from the sun is at least 254 degrees below zero.
The reason for this is that moon is a dry, dead mass of cooled-off lava, or melted rock. It has no water, no vegetation, no life, nothing to make clouds to temper the rays of the sun. If it were not for water vapor in the earth's atmosphere, we could not live on it. The blanket of vapor keeps the heat from burning us up in the daytime, prevents that heat from escaping at night.
One way astronomers can tell whether other planets than ours are probably inhabited or not is by studying their atmosphere through their great telescope. The only one, on which it seems possible, for life is what we know it to exist is Mars.
When the new 200 inch telescope is finished we will probably get evidence to the population.

Observers measure Moon's temperatures using 100-inch telescope: sunlit parts hotter than boiling water, shadowed parts -254°F below zero. Moon is lifeless lava mass without atmosphere. Earth's water vapor enables life. Astronomers study atmospheres for habitability; Mars possible. New 200-inch telescope may reveal Martian population evidence.
