Science Interest Group
Galaxies
The Galaxies Science Interest Group (Galaxies SIG) offers an opportunity for researchers across all career stages studying galaxies.
About Galaxies SIG
Exploring galaxies throughout the universe
The Cosmic Origins program is forming a science interest group (SIG) that will help NASA understand and implement recommendations from the upcoming decadal survey in the area of galaxies. This group will also sponsor discussions, research seminars, and periodic meetings.
Participating in a science interest group is an opportunity to meet people and make professional connections. It is an opportunity to learn about NASA astrophysics and share in the joy of creative science. It is also an opportunity to help others and give back to the astronomical community.
