    Asteroid Day this year, June 30, 2021, is 113 years after the Tunguska impact event in Siberia, which destroyed an area of pristine forest the size of Tokyo. With blasted and burnt tree trunks leveled and stripped bare over such a vast area, it is as though a large atomic bomb had been dropped on the forest. The debate still goes on in the research literature, but a popular theory is that this impact was caused by a small comet fragment, in the region of 328 feet (100 meters) in diameter, that exploded at an altitude of around 5 miles...

    Sunday is International Asteroid Day, commemorating the Earth's largest recorded asteroid impact while focusing on the real danger of asteroids that could collide with Earth. In 1908, a powerful asteroid struck the Podkamennaya Tunguska River area in a remote Siberian forest of Russia. Six years ago, an asteroid entered Earth's atmosphere over Chelyabinsk, Russia. It exploded in the air, releasing 20 to 30 times more energy than that of the first atomic bombs and generating brightness greater than the sun. It damaged more than 7,000 buildings and injured more than 1,000 people. The shock wave broke windows 58 miles away....

    The European Southern Observatory (ESO) and ESA (European space agency) teamed up to produce a packed Asteroid Day webcast. There were interviews with ESA and ESO scientists. Updates from Europe’s asteroid hunters and some of the most recent asteroid science results, including the blockbuster news on Oumuamua, the first-ever interplanetary visitor. The programme also included an interview with ESA astronaut Luca Parmitano on the challenges of future human missions to asteroids, as well as a surprise segment that answered the age-old question: What really killed off the dinosaurs? More than 1M asteroids have the potential to impact Earth and through...

    Heavenly bodies stir up routine catastrophes March 18 2003 at 01:30PM By Graeme Addison Legend has it that when two people get together and er... bond, the Earth will move – at least in a metaphorical sense. Likewise, it takes two heavenly bodies, an impactor and a target, to come together with Earth-shattering force to form a crater. There’s nothing dreamlike about this: it happens, frequently, throughout the solar system. Impact catastrophes are routine. Just over two-billion years ago, a chunk of asteroid at least the size of Table Mountain struck the landmass that is now South Africa. It hurtled...

    An Empire's Epidemic Scientists Use DNA in Search for Answers to 6th Century Plague By THOMAS H. MAUGH II, Times Staff Writer By the middle of the 6th century, the Emperor Justinian had spread his Byzantine Empire around the rim of the Mediterranean and throughout Europe, laying the groundwork for what he hoped would be a long-lived dynasty. His dreams were shattered when disease-bearing mice from lower Egypt reached the harbor town of Pelusium in AD 540. From there, the devastating disease spread to Alexandria and, by ship, to Constantinople, Justinian's capital, before surging throughout his empire. By the time...

    Sun's Movement Through Milky Way Regularly Sends Comets Hurtling, Coinciding With Mass Life ExtinctionsA large body of scientific evidence now exists that support the hypothesis that a major asteroid or comet impact occurred in the Caribbean region at the boundary of the Cretaceous and Tertiary periods in Earth's geologic history. Such an impact is suspected to be responsible for the mass extinction of many floral and faunal species, including the large dinosaurs, that marked the end of the Cretaceous period.
