Several transient luminous events illuminate pockets of Earth’s upper atmosphere. A line of thunderstorms off the coast of South Africa powers the rare phenomena. via NASA https://ift.tt/gQKd7lX
These three bright nebulae are often featured on telescopic tours of the constellation Sagittarius and the crowded starfields of the central Milky Way. In fact, 18th century cosmic tourist Charles Messier cataloged two of them; M8, the large nebula above center, and colorful M20 below and left in the frame. The third emission region includes […]

These clouds are doubly unusual. First, they are rare noctilucent clouds, meaning that they are visible at night — but only just before sunrise or just after sunset. Second, the source of these noctilucent clouds is actually known. In this rare case, the source of the sunlight-reflecting ice-crystals in the upper atmosphere can be traced […]

Space shuttle Columbia heads skyward after clearing the fixed service structure tower at Launch Complex Pad 39A at NASA’s Kennedy Space Center in Florida. Plant life appears in the foreground. Launch occurred at 12:43 pm Eastern Daylight Time (EDT) on July 8, 1994. Once in Earth orbit, STS-65’s six NASA astronauts and a Japanese payload […]
Do other stars have planets like our Sun? Surely they do, and evidence includes slight star wobbles created by the gravity of orbiting exoplanets and slight star dimmings caused by orbiting planets moving in front. In all, there have now been over 5,500 exoplanets discovered, including thousands by NASA’s space-based Kepler and TESS missions, and […]
Mostly Sunny today! With a high of 25C and a low of 25C. 90 Humidity. 12 C currently. 6 Km/h Wind from South.
Why are these clouds multi-colored? A relatively rare phenomenon in clouds known as iridescence can bring up unusual colors vividly — or even a whole spectrum of colors simultaneously. These polar stratospheric clouds also, known as nacreous and mother-of-pearl clouds, are formed of small water droplets of nearly uniform size. When the Sun is in […]
