It gives a strange luminosity to the hills, especially under a dark sky, adding almost a lunar atmosphere to the landscapes.

The researchers say their observations have enabled them to rule out some theories on the origin of the lunar atmosphere.

The mass spectrometer made measurements of the extremely thin lunar atmosphere.

The lunar atmosphere probably originates from outgassing of warm material below the surface.

We must not be in a hurry to proclaim the existence of a lunar atmosphere.

There were enough traces of lunar atmosphere to interfere with the readings, so the whole program was shifted out into space.

The near-absence of a lunar atmosphere means that stellar imaging is possible at many wavelengths which are not visible from Earth.

The goal was to detect and determine the composition of the lunar atmosphere.

Herschel himself never inferred from them the necessity of a lunar atmosphere.

A favorable circumstance if, as they thought, the lunar atmosphere was stored only in its depths.
