Known as the Tunguska event, the blast flattened more than 80 million trees in seconds, over an area spanning nearly 800 square miles (2,000 square kilometers) — but left no crater. A meteor that exploded before…

The Tunguska explosion could have been caused by an asteroid that still orbits the sun
On a cool summer morning in 1908, a fireball appeared over northern Siberia. Eyewitnesses described a column of blue light that moved across the sky, followed by a tremendous explosion that leveled trees across more than 2,000 square kilometers. The explosion is consistent with a large meteor strike, but to this day, no evidence of a crater has been found. Now…
Scientists scour Tunguska for ‘cosmic matter’

Earth’s 2nd largest meteorite crater much younger than thought
Earth’s biggest meteorite crater is Meteor Crater in Arizona. The 2nd biggest is Australia’s Wolfe Creek Crater, likely formed when a 50-foot meteor struck about 120,000 years ago. Source: https://earthsky.org/earth/how-old-is-wolf-creek-crater…
Arecibo gets $19M grant to find and study NEOs
NEOs are near-Earth objects, asteroids and small comets that sweep near Earth and have the potential to cause harm. Arecibo Observatory in Puerto Rico has, since the 1990s, been finding about 60 to 120 of these objects every year. Source: https://earthsky.org/human-world/arecibo-observatory-19-million-grant-neos…
