NASA has released images of a meteor exploding over the Bering Sea last December with a force over 10 times greater than the atomic bomb that destroyed Hiroshima in 1945. The giant fireball exploded 16 mi (26 km) above the Earth's surface and is estimated to have released 173 kilotons of energy.

The lack of gravity in space means that muscles begin to waste away, and scientists have been studying these health effects on Earth with extended bed-rest experiments. In the latest, those beds will be put in a centrifuge to mimic artificial gravity, to see if that can help offset the issues.

It's hard to really understand the large-scale structure of the Milky Way. Now, astronomers have peered towards the center of the galaxy using the ESA's X-ray telescope XMM-Newton, and discovered two colossal "chimneys" pumping huge amounts of energy and gas out into intergalactic space.

The universe is full of fascinating stories, and NASA’s Fermi Gamma-ray Space Telescope has just spotted a doozy. About 10,000 years ago a star went supernova, and the explosion shot the resulting pulsar off like a cannonball, with enough force to send it hurtling out of the galaxy altogether.

Humans weren’t built for space travel. The immune system takes a beating, leaving us more vulnerable to infection. Astronauts have now tested a new antimicrobial coating on board the International Space Station (ISS), and found it kept space-faring bugs at bay for well over a year.

NASA’s OSIRIS-REx spacecraft is not due to bring home samples from the asteroid Bennu until some time in 2023, but already it is turning up some fascinating discoveries about this distant world, the latest being a far rockier surface than anticipated.
