Dave Pooley, one of the discoverers of SN2006gy, says that if Eta Carinae exploded in a similar fashion, it would be bright enough that one could read by its light here on Earth at night, and would even be visible during the daytime.
SN 2006gyの発見者の一人Dave Pooleyはもしりゅうこつ座η星が同じように超新星爆発を起こせば、地球では夜でも本が読め、昼でもその明かりが見えるほどに明るくなるだろうと語っている。
