That View Though. Oval Storms Dot The Cloudscape In This Enhanced Color JunoCam Image Of Jupiter’s

esta vitoria da conquista 

You’ve just crossed over into the Twilight Zone. This image captures the swirling cloud formations in Jupiter’s terminator – the region where day meets night.

This image is one in a series of images taken in an experiment to capture the best results for illuminated parts of Jupiter’s polar region. For JunoCam to collect enough light to reveal features in Jupiter’s dark twilight zone, the much brighter illuminated day-side of the planet becomes overexposed with the higher exposure.

On that day in 1957 was launched the satellite Sputnik 1, the Earth’s first artificial satellite.

The Soviet Union launched it into an elliptical low Earth orbit on 4 October 1957, orbiting for three weeks before its batteries died, then silently for two more months before falling back into the atmosphere. It was a 58 cm (23 in) diameter polished metal sphere, with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable even by radio amateurs and the 65° inclination and duration of its orbit made its flight path cover virtually the entire inhabited Earth. This surprise success precipitated the American Sputnik crisis and triggered the Space Race, a part of the Cold War. The launch ushered in new political, military, technological, and scientific developments.
