Coronal hole

morreale Tuesday 13 of January, 2015
The Cosmos website has posted an interesting article on the coronal hole that developed on the south pole of the Sun recently. The Sun has an magnetic field that flips every 11 years. The exact details of how the coronal hole develops is not well understood, but the north pole has flipped and the south pole magnetic field flip is still catching up. This could be part of the process that causes the coronal hole.

Star and planet magnetism

morreale Thursday 20 of November, 2014
Researchers are studying the magnetic field interactions between stars and their orbiting planets with magnetic fields. 3D models of this magnetic field interaction indicate that a planet with a magnetic field can induce hot spots on the surface of its sun. This may lead to another means of detecting exoplanets.


Comet landing

morreale Tuesday 11 of November, 2014
The ESP Rosetta spacecraft will be dropping a lander onto the comment 67P/Churyumov–Gerasimenko tomorrow. It's a wild mission and mission scientist need a lot of luck for the lander to successfully land on the comment. It turned out the comet 67P is vastly different than what they planned on landing on as the intended comet could not be found.
