Astronomers imaged a snow line in a protoplanetary disk with ALMA – a step towards a better understanding of the theory of planet formation.
I’ve got pretty bad eyesight. If I take off my glasses and look at the flowers on my window sill, they look like a fuzzy yellow blob. But with glasses, the petals and the patterns cast on them come into focus. This is how I felt when looking at the new observations of the debris disk around AU Mic. Putting on our ALMA glasses, the fuzzy debris disk around AU Mic is sharpening into something surprisingly consistent with our own Solar System.
Amid all of the swirling chaos during star formation, the universe finds a way to order its diffuse gas into shining young stars. ALMA Science Verification observations give new insight.
Molecular outflows are important components of the star formation process. These authors present observations of a butterfly-shaped outflow in Orion, and present several possible scenarios for this morphology.
This paper presents ALMA observations of the first ever measurement of both ionized nitrogen and carbon for the galaxy “LESS J0332”, which is determined to be at a redshift of 4.76 and have a metallicity similar to that of our sun. This suggests that the galaxy at a much earlier time in the universe had already evolved quite a bit.
