  • Immense fireball Rips Across Tokyo, sonic boom reported

    A bright fireball streaked across Japan's capital Tokyo at 17:32 UTC on July 1, 2020 (02:32 JST, July 2). Many people reported hearing a sonic boom minutes after the meteor exploded, which is considered rare, according to the National Astronomical Observatory.

    Daichi Fujii, a curator at Hiratsuka City Museum in Kanagawa Prefecture, caught the spectacular phenomenon with a camera installed at his home. The fireball traveled from west to east. 

    Many residents reported hearing a sonic boom minutes after the fireball exploded.

    "A few minutes later, I heard a roar that could be heard indoors, which may be relevant," one of the locals said.

    "I thought a person living [in the condo] above knocked down a shelf," one Twitter user wrote.

    "I thought my child sleeping on the second floor fell out of bed," another one posted. Other residents said the explosion sounded like a thunder.

    Chief Cabinet Secretary Yoshihide Suga announced at a national press conference that authorities are gathering information about the event, adding that no damage has been reported so far.

    The National Astronomical Observatory said it is rare for witnesses to hear anything after a fireball event.

    "One station of the International Monitoring System of the Comprehensive Nuclear-Test-Ban Treaty Organisation was almost 1 150 km(715miles) away from the event but in its waveforms a signature of the fireball could be identified," International Meteor Organization's Theresa Ott and Esther Drolshagen noted.

    "We were able to calculate source energy of the entering asteroid of about 150 t TNT. With an assumed velocity of 14 km/s and a density of 3000 kg/m3 the size would be around 1.6 m (5.2 feet), with a mass of about 1.6 t."

  • Large Asteroid Blazes Across the Sky in Australia

    Residents from Western Australia to Victoria Australia have witnessed an amazing light show when the night sky turned glowing green as a huge asteroid blazed across Australia on June 14, 2020.

    Australian skywatchers have been treated to a stunning show by what astronomers believe was a distant asteroid.

    Residents from across Australia shared vision to social media of the object streaking across the sky on Sunday night, creating a green glow.

    Night owls in a remote part of western Australia captured a stunning green fireball streaking across the night sky.

    Astronomers believe it was “asteroid 2002 N-N-4,” which was scheduled to pass Earth around 11:20 p.m. on Sunday.

    The asteroid, around 570 metres wide, was an estimated 5.2 million kilometres from Earth, but still created a spectacular light show. 

    The asteroid was seen from Victoria to Western Australia and it created a stunning green glow in the sky as it passed by.

    NASA had identified 958,703 asteroids, and said impacts with Earth can be expected every 200-300 years. 

    Asteroids range in size from Vesta, the largest at about 530 kilometers in diameter, to bodies that are less than 10 meters across,‘ a NASA statement read.

    We were lucky, asteroid 2002 NN4 was millions of kilometers away. The next time 2002 NN4 will be anywhere near this close to the Earth will be in June 2029.

    The latest asteroid event over Australia just shows that our technology isn’t ready to hinder a catastrophic impact right now.
