Defying expectations, solar activity is back in a big way, with the number of sunspots counted on the Sun’s surface last month reaching levels not seen in nearly 23 years, more than twice the number predicted by previous forecasts. This newfound activity signals not only that the Sun is wellread more
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
