The rings formed like ripples in a pond after a blue dwarf galaxy ripped through LEDA 1313424’s heart some 50 million years ago. (The interloper appears just left of center.) ...

This is part of what makes galaxy clusters like PLCKG 287.0+32.9 (pronounced “Planck 287” for short) interesting to astronomers — “they carry memories of our early universe, therefore ...

The Associated Press reported last week that astronomers in Finland have determined that our galaxy has a 50-50 chance of colliding with the neighboring Andromeda within the next 10 billion years.
