Blowing bubbles in the Milky Way’s magnetic field

June 1, 2016 An international team of astronomers has discovered a possible connection between the magnetic fields of supernova remnants and that of our own Milky Way Galaxy. The study, recently published in the journal Astronomy & Astrophysics, found that the orientation of supernova remnants can help astronomers understand the nature and shape of the …

Close-up view of galaxies prompts re-think on star formation

This is the “South Pillar” region of the star-forming region called the Carina Nebula. Like cracking open a watermelon and finding its seeds, the infrared telescope “busted open” this murky cloud to reveal star embryos tucked inside finger-like pillars of thick dust. Credit: NASA November 10, 2015 Astronomers have identified for the first time one …
