But then there comes that moment rare
When, for no cause that I can find,
The little voices of the air
Sound above all the sea and wind.

The sea and wind do then obey
And sighing, sighing double notes
Of double basses, content to play
A droning chord for the little throats—

The little throats that sing and rise
Up into the light with lovely ease
And a kind of magical, sweet surprise
To hear and know themselves for these—

For these little voices: the bee, the fly,
The leaf that taps, the pod that breaks,
The breeze on the grass-tops bending by,
The shrill quick sound that the insect makes.

NASA Astronomy Picture of the Day:

In the words of today's astrophotographer, Rositsa Dimitrova, "What have these silent sentinels watched pass across the sky?" The volcanic mo'ai (meaning statue) of Ahu Tongariki stand guard over Rapa Nui (Isla de Pascua, Easter Island), a Polynesian island (annexed by Chile in 1888) located thousands of kilometers off the coast of South America in the Pacific Ocean. Due to the island's remoteness, the mo'ai, with their backs to the dark ocean, are able to gaze upon a clear and vibrant night sky. Pictured, these larger-than-life statues stare at the bright band of the Milky Way, partly obscured by interstellar dust and blurred by Earth's clouds. Under such clear night skies, the Rapa Nui created observatories and used astronomical observations for navigation, calendar calibration, celebrations, and more. Images like this one remind us of the importance of dark skies, protecting the land underneath them, and preserving the culture that they inspire.

NASA Astronomy Picture of the Day:

Is gravity the same over the surface of the Earth? No -- in some places you will feel slightly heavier than others. The featured Earth map video shows in colors and exaggerated highs and lows where the gravitational field of Earth is relatively strong and weak. A low spot, where you would feel slightly lighter, can be seen just off the coast of India, in blue, while a relative high occurs in the mountains of Chile in South America. The cause of these irregularities does not always follow present surface features. Scientists hypothesize that other important factors lie in deep underground structures in Earth's mantle and may be related to the Earth's appearance in the distant past. The featured map was composed from data taken by NASA's twin GRACE satellites that orbited the Earth from 2002 to 2017. GRACE mapped Earth's gravity by carefully tracking tiny changes in the distance between the two satellites.
