Nearly imperceptible quantum flickers used to limit how precisely we could detect the way space-time ripples, but squeezing the laser light used in detectors overcomes this and doubles the number of gravitational waves we can see

Genetic analysis shows that microbes growing inside the International Space Station have adaptations for radiation and low gravity, and may pose a threat to astronauts

Medically evacuating an astronaut from space is difficult and expensive, and a new model predicts that one in three long-duration moon missions may require it

A distant planet should have been consumed when its star expanded to become a red giant, perhaps offering insights into planetary migration

Astronomers listened for radio signals emanating from planets in the TRAPPIST-1 system, but found no evidence of any interplanetary communications

A computer simulation suggests that some collisions between exotic, hypothetical stars would make space-time ripple with detectable waves

The first 18 satellites of a planned Chinese mega constellation are brighter than all but 500 stars in the sky, raising fears of a huge impact on astronomy
