galaxy is a vast system of stars, #space #galaxies #shorts

A galaxy is a vast system of stars, gas, dust, and dark matter, held together by gravity. It is one of the fundamental building blocks of the universe. There are billions of galaxies in the universe, varying in size, shape, and composition. Our own galaxy, the Milky Way, is a barred spiral galaxy containing hundreds of billions of stars. Galaxies can be classified into different types, including spiral, elliptical, and irregular, based on their shape. They can also interact and collide with each other, leading to the formation of new stars and the restructuring of the galaxies. The study of galaxies, known as galactic astronomy, helps in understanding the evolution and structure of the universe

4. Collaborative Missions: NASA often collaborates with international partners on major space missions. For instance, the Mars Science Laboratory (Curiosity Rover) mission involved contributions from numerous international researchers and institutions. These collaborations help leverage expertise and resources from multiple countries and increase the scientific output of such missions.

5. Joint Research Projects: NASA supports collaborative research projects involving international scientists and institutions. Through various programs and grants, NASA fosters scientific cooperation to address fundamental scientific questions and advance our understanding of space exploration-related topics.

Overall, NASA actively engages in international collaborations and strives to share its findings and knowledge with the global scientific community. These efforts promote cooperation, enable scientific advancements, and increase our understanding of the universe.
