High circular polarization (the red and white regions in the image) observed in the infrared light from reflection nebulae in the star-forming region Orion OMC1 (Bailey et al. 1998). It is caused by alignment of the dust particles in magnetic field,...

Version 0.15.1 introduces a few new exciting features. - The Digital Sky Survey (DSS) can be shown (requires online connection). - AstroCalc is now available from the main menu and gives interesting new computational insight. - Stellarium can act...

AAS Nova: Editor’s note: In these last two weeks of 2016, we’ll be looking at a few selections that we haven’t yet discussed on AAS Nova from among the most-downloaded papers published in AAS journals this year. The usual posting schedule will resume...

We have studied formation of galactic outflows from supernova explosions (SNe) with the moving-mesh code AREPO in a stratified column of gas with a surface density similar to the Milky Way disk at the solar circle. The movie shows a comparison of different...

We have developed a method for deriving the distribution of the Milky Way's interstellar medium as a function of longitude, latitude, distance and line-of-sight velocity. This method takes as input maps of reddening as a function of longitude, latitude...
