For the second time in history, a human-made object has reached the space between the stars. NASA’s Voyager 2 probe now has exited the heliosphere – the protective bubble of particles and magnetic fields created by the Sun.

A startup is developing a 100-gigawatt laser to propel a probe to another star system. That may be powerful enough to 'ignite an entire city. JPL, Honda and CalTech make a better battery!

Listen to Martian wind blow across NASA’s InSight lander. The spacecraft’s seismometer and air pressure sensor picked up vibrations from 10-15 mph (16-24 kph) winds as they blew across Mars’ Elysium Planitia on Dec. 1, 2018.
