In recent years, certain luminous extragalactic optical transients have been observed to last only a few days1. Their short observed duration implies a different powering mechanism from the most common luminous extragalactic transients (supernovae), whose timescale is weeks2. Some short-duration transients, most notably AT2018cow (ref. 3), show blue optical colours and bright radio and X-ray emission4. Several AT2018cow-like transients have shown hints of a long-lived embedded energy sourc...

By Dean Murray A galaxy has mysteriously redirected a powerful jet of radiation at Earth. Research has revealed that galaxy, named PBC J2333.9-2343, has changed the direction of the jet “drastically by an angle of up to 90 degrees”. A study by a team of international astronomers explains the jet is observed “going from being

The event marks the first observation of a reorientation so dramatic that it changes the category a galaxy fits into.
