Россия надеется, что польские власти пересмотрят свои планы относительно сноса советских памятников, заявила официальный представитель МИД РФ Мария Захарова.
Given how brief the flash was, and how bright, I’m sure it wasn’t terribly big, probably in the tens-of-meters wide range. I know that sounds small, but remember, Jupiter has ferocious gravity, and velocity is critical here! The energy released by an object slamming into another depends linearly on the mass (double the mass, double the energy), but on the square of the velocity: double the velocity, quadruple the energy.The average velocity of an object impacting Jupiter will be five times greater than an object colliding with Earth, meaning that the impact energy will easily be 25 times as high — which is why even a rock smaller than a football field can make a splash visible to amateur telescopes from over 400 million miles away. In fact, similar flashes on Jupiter have been caused by rocks just 10 meters (32 feet) across.
