What created this giant X in the clouds? It was the shadow of contrails illuminated from below. When airplanes fly, humid engine exhaust may form water droplets that might freeze in Earth’s cold upper atmosphere. These persistent streams of water and ice scatter light from the Sun above and so appear bright from below. On […]

Behold one of the more detailed images of Earth. This Blue Marble Earth montage—created from photographs taken by the Visible/Infrared Imager Radiometer Suite (VIIRS) instrument aboard the Suomi NPP satellite—shows many stunning details of our home planet. via NASA https://ift.tt/wyH0Yql
Yes, but can your volcano do this? To the surprise of some, Mt. Etna emits, on occasion, smoke rings. Technically known as vortex rings, the walls of the volcano slightly slow the outside of emitted smoke puffs, causing the inside gas to move faster. A circle of low pressure develops so that the emitted puff […]
Partly Cloudy today! With a high of 8C and a low of 8C. 84 Humidity. 2 C currently. 13 Km/h Wind from Northeast.
Watch Juno zoom past Jupiter. NASA’s robotic spacecraft Juno is continuing on its now month-long, highly-elongated orbits around our Solar System’s largest planet. The featured video is from perijove 16, the sixteenth time that Juno passed near Jupiter since it arrived in mid-2016. Each perijove passes near a slightly different part of Jupiter’s cloud tops. […]
Snow to Rain today! With a high of 6C and a low of 6C. 98 Humidity. 3 C currently. 11 Km/h Wind from Southwest.
When the dark shadow of the Moon raced across North America on April 8, sky watchers along the shadow’s narrow central path were treated to a total solar eclipse. During the New Moon’s shadow play diamonds glistened twice in the eclipse-darkened skies. The transient celestial jewels appeared immediately before and after the total eclipse phase. […]
Showers today! With a high of 8C and a low of 8C. 90 Humidity. 4 C currently. 11 Km/h Wind from Southwest.
This image from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) of star-forming region NGC 604 shows how stellar winds from bright, hot young stars carve out cavities in surrounding gas and dust. via NASA https://ift.tt/iSaZpxP
