‘Old Faithful’ galaxy has brilliant outbursts every 114 days

An “Old Faithful“-like event in space may shed light on the nature of stars near supermassive black holes embedded in galaxies.

Researchers saw repeated outbursts — every 114 days, on average — in a galaxy some 570 million light-years away from Earth. (For perspective, the nearest star system to Earth is roughly 4 light-years away.) The event, known as ASASSN-14ko, is flaring vehemently and in several wavelengths of light.
