Explanation: No sudden, sharp boundary marks the passage of day into night in this gorgeous view of ocean and clouds over our fair planet Earth. Instead, the shadow line or terminator is diffuse and shows the gradual transition to darkness we experience as twilight. With the Sun illuminating the scene from the right, the cloud tops reflect gently reddened sunlight filtered through the dusty troposphere, the lowest layer of the planet's nurturing atmosphere. A clear high altitude layer, visible along the dayside's upper edge, scatters blue sunlight and fades into the blackness of space. This picture was taken in June of 2001 from the International Space Station orbiting at an altitude of 211 nautical miles. Of course from home, you can check out the Earth Now.

<<In Norse mythology, Ragnarök is a series of events, including a great battle, foretold to lead to the death of a number of great figures (including the gods Odin, Thor, Týr, Freyr, Heimdallr, and Loki), natural disasters and the submersion of the world in water. After these events, the world will resurface anew and fertile, the surviving and returning gods will meet and the world will be repopulated by two human survivors. The singular form ragnarøk(k)r is found in a stanza of the Poetic Edda poem Lokasenna, and in the Prose Edda. The noun røk(k)r means "twilight" (from the verb røkkva "to grow dark"), suggesting a translation "twilight of the gods.">>
Götterdämmerung (Twilight of the Gods), is the last in Richard Wagner's cycle of four music dramas titled Der Ring des Nibelungen (The Ring of the Nibelung, or The Ring for short).
The title is a translation into German of the Old Norse phrase Ragnarök, which in Norse mythology refers to a prophesied war among various beings and gods that ultimately results in the burning, immersion in water, and renewal of the world. Wagner's account diverges significantly from his Old Norse sources.
The three Norns, daughters of Erda, gather beside Brünnhilde's rock, weaving the rope of Destiny. They sing of the past and the present, and of the future when Wotan will set fire to Valhalla to signal the end of the gods. Without warning, their rope breaks. Lamenting the loss of their wisdom, the Norns disappear.
As day breaks, Siegfried and Brünnhilde emerge from their cave, high on a mountaintop surrounded by magic fire. Brünnhilde sends Siegfried off to new adventures, urging him to keep their love in mind. As a pledge of fidelity, Siegfried gives her the ring of power that he took from Fafner's hoard. Bearing Brünnhilde's shield and mounting her horse Grane, Siegfried rides away as an orchestral interlude (Siegfried's Journey to the Rhine) starts.>>
The "you can check out the Earth Now" link (https://climate.nasa.gov/earth-now) - from the description shows a gaping absence of data over Antarctica. Anyone know why?
