New Stars on the Block
  Groups of young stars located in the solar neighborhood have recently received a lot of attention. These stars, which are $\lesssim$ 10 million years old, can provide insights into the birth of stars and planetary systems. For example, the TW Hydrae Association is just at the age when planets are believed to form, while MBM12 represents an earlier stage. In this Perspective, I briefly discuss recent research in this field.
