As­tro­no­mers have used com­put­er sim­ula­t­ions to cal­cu­late that a black hole at the heart of one the larg­est near­by ga­lax­ies is two to three times heav­i­er than pre­vi­ously thought.

Weigh­ing the equiv­a­lent of about 6.4 bil­lion Suns, the black hole in gal­axy M87 is the most mas­sive yet meas­ured with a re­li­a­ble tech­nique, and sug­gests that the ac­cept­ed black hole mass­es in near­by large ga­lax­ies may be off by si­m­i­lar amounts, ac­cord­ing to re­search­ers.
