A seemingly regular, Sun-like star began acting really weird, flickering haphazardly as its light faded in and out. The cause of the star’s strange behavior may have been a cosmic catastrophe that’s ...

The Sun has been a powerful source of energy fueling the solar system for billions of years, but our host star may have had rough beginnings. A new study suggests the Sun migrated away from the center ...

A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown mini-galaxy leftover from an ancient cosmic crash. The "collision within a collision" ...

A selection of active galaxies with supermassive black holes at their centers, illustrating the variety of shapes that can result from the activity of black holes and their interaction with the ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the ...

Most of the time, Professor of Physics and Engineering Jay Tang and Ph.D. candidate Thomas Dutta GS research the movement of bacteria in water. But their new study takes fluid mechanics beyond the lab ...

Astronomers from UCT have uncovered the true scale of one of the largest hidden structures in the nearby Universe.

Analysis reveals what appears to be a channel of hot, low-density plasma stretching out from our solar system toward distant ...

For billions of years before reaching its current location, the Sun may have slowly travelled as part of a large group, or “wave,” of stars drifting out from the inner parts of the Milky Way. This ...

For four decades, many SETI experiments have focused on finding sharp spikes in frequency but the new study says signals may not stay narrow as they travel away from their home system.
