A NASA astronomer explains how astronauts dispose of their, uh, dark matter.
- When nature calls in micro-gravity, astronauts must answer. Space agencies have developed suction-based toilets – with a camera built in to ensure all the waste is contained before "flushing".
- Yes, there have been floaters in space. The early days of space exploration were a learning curve!

It has already found several bizarre planets outside of our solar system.
- The Kepler program closed down in August, 2018, after nine and a half years of observing the universe.
- Picking up where it left off, the Transiting Exoplanet Survey Satellite (TESS) has already found eight planets, three of which scientists are very excited about, and six supernovae.
- In many ways, TESS is already outperforming Kepler, and researchers expect it to find more than 20,000 exoplanets over its lifespan.
China's Chang'e 4 biosphere experiment marks a first for humankind.
