NASA explores the mysterious in air and space, innovates for the good thing about humanity, and evokes the world via discovery.
The modern era of physical cosmology started in 1917, when Albert Einstein 1st applied his typical principle of relativity to product the structure and dynamics of your universe.[224] The discoveries of the era, and the concerns that continue to be unanswered, are outlined during the sections higher than.
Although Earth is only the fifth greatest planet inside the solar system, it is the only world in our photo voltaic system with liquid water around the surface area.
