We will one day grow food in conditions as extreme as Mars. Developing the controlled environments required will help not only space explorers but also support our own survival here on Earth.
These ripples in the very fabric of the universe were hypothesized by Einstein a century ago. Now scientists have detected them for the third time in a year and a half – ushering in a new era in astrophysics.
To get us to Mars and beyond, a team of students from around the world has a plan involving lunar rovers mining ice and a space station between the Earth and the moon.
People used to think that when they looked up at the night sky, they were seeing all of space. Then American astronomer Edwin Hubble found out something so amazing, NASA named a telescope after him.
Astronomers are surprised by what they’re finding out about galaxies that formed in the early days of our universe, now that sensitive telescopes allow direct observation, not the inference of old.
Every moment of life on our planet has had the force of gravity in the background. But the prospect of long-distance space travel means it’s time to figure out what happens to our biology in its absence.
