Hi everyone, how are you doing? This is my last post for this school year and I thought of making it something straightforward and captivating at the same time. Surfing the Net I found five breathtaking pictures that I want to share just to make you witness the magnificence of our world ...... so fasten your seatbelts and get ready for an astonishing voyage!
THE GALAXY TREE
This picture taken in the town of Salamanca shows the silhouette of a pruned oak tree ''witnessing'' the Milky Way galaxy . Thanks to the alignment of the two , the dust lanes in the galaxy appear to be natural continuations to branches of the tree and the relatively bright horizon maintain a certain contrast with the background .
THE JELLYFISH AND MARS
In this alluring scene , the elusive nebula is surrounded by two yellowish stars, Mu and Eta Geminorum ( on the left ) and by Mars (on the right ). The Jellyfish Nebula itself floats below and left of center , a bright arcing ridge of emission with dangling tentacles . In fact , the cosmic jellyfish is part of bubble-shaped supernova remnant IC 443 , the expanding debris cloud from a massive star that exploded .
LIGHTNING AND ORION BEYOND ULURU
Uluru is an extraordinary 350 meters high mountain in central Australia that rises sharply from nearly flat surroundings . Composed of sandstone , Uluru has slowly formed over the past 300 million years as softer rock eroded away . In the photo to the left of the monumental formation a raging thunderstorm is visible and raising our eyes, the constellation of Orion is discernible in the sky full of stars .
SPACE STATION, SOLAR PROMINENCE, THE SUN
The ambiguous dot in the center is not a sunspot . It's the International Space Station caught passing in front of the Sun . Sunspots , individually , have a dark central umbra and a lighter surrounding penumbra . By contrast , the ISS is a complex and multi-spired ( da spire inteso come pinnacolo non so se si può scrivere così ) mechanism , one of the largest and most complicated spacecraft created by humanity .
RED SPRITE LIGHTNING OVER THE ANDES
This image was taken from Las Campanas observatory in Chile over the Andes Mountains in Argentina .These baffling-red filaments are called ''red sprites ''. Recent researches have shown that following a powerful positive cloud-to-ground lightning strike , red sprites may start as 100 meter balls of ionized air that shoot down from about 80km high at 10% speed of light. They are quickly followed by a group of upward streaking ionized balls .
