NASA Scientists and Astronauts Practice for Space Missions on the Seafloor

A female-led crew trained for nine days in an undersea laboratory in the Atlantic to get a sense of what it’s like to live and work in microgravity

An artist's visualization of the star S0-2 as it passes by the supermassive black hole at the galactic center. As the star gets closer to the supermassive black hole, it experiences a gravitational redshift that is predicted by Einstein's general relativity. By observing this redshift, we can test Einstein's theory of gravity.
