A bright meteor was caught in many dashcam videos – in broad daylight – on April 6, 2019, over the Russian city of Krasnoyarsk. See a video compilation here.
The raw materials from a comet have been found sealed inside a pristine, primitive meteorite.
While two of these space rocks are not coming back any time soon, the other two hit their closest approach to Earth for a long while to come.
Climate change is a serious threat to human society. But even the most extreme worst-case future scenario wouldn’t wipe out humanity instantly. There’s only one thing that might do that — a major asteroid or comet impact.
Metallic asteroids are the cooled cores of disrupted planetesimals. They originated early in the history of our Solar System when planets were beginning to form. University of California Santa Cruz planetary researchers Jacob Abrahams and Professor Francis Nimmo think that as the metal cooled and solidified, volcanoes spewing liquid iron could have erupted through a solid iron crust onto the surface of the metallic asteroid.
Scientists hope samples from Hayabusa 2 will provide clues about origins of life on Earth
Research that had been kept secret for years that captured a fossilized snapshot of the day nearly 66 million years ago when an asteroid hit Earth, wiping out nearly all life on the planet, including the dinosaurs, has finally been released, shocking the scientific community.
The asteroid is estimated to be twice as big as the Pyramid of Khufu in Giza and will return for another visit 16 years from now.
A shock discovery is in from Bennu. The NASA spacecraft analysing the asteroid has observed it shooting out plumes of dust that surround it in a dusty haze – a phenomenon we’ve never seen in an asteroid before.
