Winners of the Close-up Photographer of the Year 2021The top 100 winners of Close-up Photographer of the Year 03 (2021) or CUPOTY 03 are now featured on its website showing the winners gallery.The Close-up Photographer of the Year website was the brainchild of husband-and-wife duo Tracy and Dan Calder of Winchester, UK. They wanted to put close-up, macro and micro photography on the center stage and be celebrated in its own right.Tracy, a former editor of Outdoor Photography and a features editor at Amateur Photography, has over 20 years experience in the photo magazine industry. She’s also a photography instructor at West Dean College in Sussex, and an author of Close-up & Macro Photography, which has been translated into French and Chinese. Dan is a contributor to Black + White Photography magazine.This year’s Close-up Photographer of the Year (CUPOTY 03) has more than 9000 photos from 55 countries across nine different categories. These categories are insects, animals, plants and fungi, underwater, butterflies and dragonflies, intimate landscape, manmade, micro, and young.From each category, the top three winners were chosen alongside with the other finalists. Here are the top three winners per category.#photography #CUPOTY #MacroPhotography #CloseupPhotography #photographycompetitionInsects

Meteorite Crashes Landed on a Woman's Bed while She Slept, Barely Missing Her HeadA meteorite crashes on the bedroom of a woman's home in Golden, B.C. Ruth Hamilton was sound asleep when the sound of her dog barking woke her up. She said in an interview that the next thing that happened was just a huge explosion and that debris was all over her face. As she rolled back the pillows where she was sleeping, a charcoal-grey chunk of rock, roughly the size of a melon, was found. After piercing into the roof, the meteorite that landed on the floral pillowcases was just inches away from Hamilton's head before getting up at the sound of the dog’s bark. That was a close call!Initially, the meteorite was suspected to be debris from a construction site on a nearby highway. After reporting the rock to a team of experts from the Western University in London, Ont., the meteorite was confirmed to come from space.All Images: Ruth Hamilton#Meteorite #CloseCall #Astronomy

Dashcam Footage Used to Calculate Trajectory and Track the Location of Meteorite in SloveniaFebruary 28, 2020. People in southern Slovenia were suddenly disturbed with loud explosions and a 3.5-second flash which left a visible trail of dust. A bright ball of light in the sky was also seen in various countries on that day. It was recorded in dashcams, helmets, and security cameras.The ball of light in question was a rock from a distant asteroid. The rock was about one meter across and weighed about four metric tons before entering our atmosphere before it broke down into 17 pieces.But where exactly did these rocks fall? To solve this, scientists have combined observations from cameras to measure the trajectory of the fireball. In doing so, they can determine where in the Solar System it came from, and where it went. This approach proved effective at night. However, because the ball was spotted during the day, scientists needed a different method. They asked local people to take pictures from various locations to help compute the trajectory.See the full story over at the Europlanet Society.(All Videos: Europlanet Society)#Meteorite #TrajectoryCalculation #Asteroid #SpaceRock #Slovenia

Early Earth was Regularly Hit by City-Sized AsteroidsScientists know that early Earth was bombarded by meteor strikes, but new analysis revealed that the number of those impacts were actually much, much higher than originally thought.The size of the meteor was also much larger - some are city-sized asteroid, with estimated size of more than 10-km wide."We have developed a new impact flux model and compared with a statistical analysis of ancient spherule layer data. With this approach, we found that current models of Earth’s early bombardment severely underestimate the number of known impacts, as recorded by spherule layers", said Physicist Simone Marchi of the Southwest Research Institute in Boulder, Colorado."The true impact flux could have been up to a factor of 10 times higher than previously thought in the period between 3.5 and 2.5 billion years ago. This means that in that early period, we were probably being hit by a Chicxulub-sized impact on average every 15 million years. Quite a spectacle!"The Chicxulub impact was caused by a 10 km (6.2 miles) diameter asteroid, and was thought to cause a mass extinction of 75% of plant and animal species on Earth, including all non-avian dinosaurs.Via EurekAlertImage: Meteor Crater in Arizona, which was the result of an impact of a 50 meter (164 feet) meteor, by Dr Dale Nations/AZGS.#meteor #asteroid #massextinction #meteorite #EarlyEarth #ChicxulubImpact
