A meteoroid that skimmed across Earth’s atmosphere at more than 35,000 miles per hour before flying back out into space was a rare example of a ‘grazing fireball.’ The 808 mile (1,300 km) -long fiery trail formed by the space rock as it began to burn up in the atmosphere was spotted over Australia in the July of 2017. Only a limited number of such events have been scientifically observed — including a procession of meteors seen in 1860 — with the latest notable for its low altitude. Scroll down for the video A meteoroid, pictured from four viewpoints, that skimmed across Earth’s atmosphere at more than 35,000 miles per hour was a rare example of a ‘grazing fireball’ The fireball was observed by space scientist Patrick Shober of Australia’s Curtin University in July 2017 using the so-called ‘Desert Fireball Network’. This is the largest meteoroid-tracking network in the world — which covers 64.7 million square miles (2.5 million square kilometres), or a third of the Australian skies — with its set of 50 autonomous cameras. ‘The meteoroid transited the atmosphere for over 90 seconds and reached a minimum height of 58.5 km before returning to interplanetary space,’ the researchers… Read full this story
