Blue Origin’s all-female space flight crew, which includes popstar Katy Perry, is set to take off this spring.
Whether a galactic environment has the right conditions for habitable planets to form could depend on how the black hole in that galaxy is rotating.
An astronomer says goodbye to Gaia, the satellite that mapped the galaxy.
As ‘space tourism’ grows and private companies become more involved in orbital missions, space law has failed to keep up. Urgent reform is called for.
