A new paper from an international team of physicists has outlined the possibility that we may be able to detect the gravitational waves that spill out of a malfunctioning warp drive—provided a spacetime-bending craft belonging to one of our interstellar neighbors happens to be nearby—using technology that is already lookingread more
A potential biosignature indicating the presence of ancient lifeforms has turned up in a rock on the surface of Mars, in the form of what may be traces of chemical reactions from the life processes of ancient microbes. Although the sample will need to be returned to Earth to confirmread more
The most powerful solar storm in twenty years has just occurred, generated from a large cluster of sunspots that produced five X-class solar flares and three coronal mass ejections that resulted in a weekend-long geomagnetic storm strong enough to cast aurorae as far south as Hawaii, and in the southernread more
Earth’s night sky could have a “new” star blaze into the firmament over the next few months—despite humans having already seen this star a number of times throughout our history—in the form of what is known as a recurrent nova. Located between Hercules and Boötes, this recurrent stellar nova willread more
