Here and There
The Very Quiet Solar Wind (Sky and Telescope)
.The solar wind's lack of punch has never been less in 50 years. It is weaker than expected even for the current era of the Sun's inactivity.
Fermi Spacecraft : More Gamma Ray Pulsars (NASA)
Ordinary pulsars are detected by means of their narrow beam radio signals or x-ray emissions. Some pulsars have remained hidden because they are oriented such that the beams miss Earth. They do, however, emit more broadly in gamma rays. Fermi finds these.
Milky Way Galaxy : Has 4 Arms, More Mass, and Spins Faster (National Radio Astronomy Observatory)
New observations give the Milky Way more arms. The mass and the spin have also increased. It is now thought to be more massive than the well known galaxy in Andromeda though the latter has more stars.

New Cosmic Background Radiation (Goddard Space Flight)
This background is a radio hiss. It is a relatively loud hiss.
Methane From Mars (NY Times)
Is it from Martian bacteria, dead or alive? Is it from volcanoes? In any case it came from Terra Sabae, Nili Fossae, and Syrtis Major.
