Bridging the Gap between Climate and Weather
The distinction between climate and weather was expressed most succinctly by science fiction writer Robert A. Heinlein: “Climate is what you expect; weather is what you get.” But as global warming produces more noticeable changes on a planetary scale, how do we even know what to expect in a particular region?

High-Mass Star Formation
The formation of high-mass stars remains one of the most significant unsolved problems in astrophysics
These stars, with masses from 10 to 100 times the mass of our sun, eventually explode as supernovae and produce most of the heavy elements in the Universe. They also have a major influence on the structure and evolution of galaxies. But observing the formation of massive stars is difficult, because they are born in distant, dense, and dusty regions of space, and they swallow up much of their birth environment as they are born.
