Four Spiral Arms Walk into a Bar…
Mapping the structure of dense gas in the Milky Way is a huge undertaking… which is why we have huge surveys!

ALMA line survey shows chemical abundances of several complex organic molecules are similar across four different molecular clouds with hugely varying properties!
When molecular clouds collide, spectacular things can happen, including star formation!
The discovery of table salt and super-heated water in two massive protostellar disks hints at a new type of “hot-disk” chemistry.
A spectral line survey toward two nearby protoplanetary disks discovers new molecules and offers a comprehensive view of disk chemistry.
In the last few years, astronomers have used ALMA to measure circumstellar disk masses for the first time, but found most of the mass to be missing. If these low disk masses are real, they would suggest planet formation is much faster than we think! But could it be that this missing mass is there and we just can’t see it?
