A few astro physics news :
|| Planet X might be a black hole.
Planet X, the assumed planet that circles sun from 10 times distance of sun-pluto, might be a small black hole instead - scientists say. And if that's true, then the universe is full of small blackholes and we can substitute these blackholes for dark matter, the unfound substance that solves the puzzle of what holds the galaxies in place.
|| Four asteroids to pass earth today
One will pass at 40% distance of earth-moon and sized like a car. The others though larger will pass further than the moon and thus don't count. The thing is, all these were discovered at the last hour, and IF they were on a collision course, we won't had time to prepare.
|| Solar black spot at historic low.
Historic as in lowest in a hundred years. Resulting in cosmic rays hitting earth even more as sun's magnetic field deter those. Another article says its only a matter of time that a catastrophic solar mega storm will hit earth. This happens every 100 years.
Interestingly we are between fire and ice. Too less solar activity and we are hit by cosmic rays from space. Too much and we are hit by solar flare. A third article says this is one reason why life can't exist on other planets. There's a delicate balance which is an extremely rare phenomenon.
Earth is almost one of its kind.
