Chicken Asteroid #WrongWay #

99.99% of objects in the solar system orbit the Sun in the same direction – counter-clockwise as viewed from above the up above the Earth’s North pole. But, as always, there is always the odd exception to prove the rule. This newly discovered asteroid is in a giant game of chicken with Jupiter

Wrong-Way, Daredevil Asteroid Plays ‘Chicken’ with Jupiter

Astronomers have found a bizarre asteroid orbiting the sun in the wrong direction while playing a risky game of “chicken” with the largest planet in the solar system.

The unnamed asteroid shares Jupiter’s orbital space while moving in the opposite direction as the planet, which looks like a recipe for a collision, astronomers said. Yet somehow, the asteroid has managed to safely dodge Jupiter for at least tens of thousands of laps around the sun

 

The Hunt for Life #Aurora #Juno

Aurora on Earth are caused by particles from the Sun interacting with our planet’s protective magnetic field. Without that magnetic field on Earth, we would not be here. All life is entirely dependent on the shielding that our magnetic field provides. So if we are to search for life elsewhere, one good way to separate out those planets that may harbor life from those that do not, will be to search for Aurora. Except we’re not at the stage in our technology where we can image planets around other stars well enough to see aurora. So we have to find another way.

Luckily, the aurora also produces radio waves. So instead of watching, we can listen.
