Milky Way Alert –“Sagittarius A* Our Galaxy’s Black Hole Suddenly Flashing 75-Times Brighter”

A UCLA astronomer at the Keck Telescope, astrophysicist Tuan Do, Deputy Director of the Galactic Center Group, reports that in the space of two hours, the brightness of black hole the heart of our galaxy usually a passive flickering object about twenty-five thousand light years from Earth, has increased 75-fold – the brightest it has been since scientists first started studying it more than 20 years ago.

Do was watching the Keck telescope in Hawaii as it was pointed at the center of the Milky Way on the evening of May 12. He reports that he was baffled by an unusually bright spot on the readings at first, thinking it was the nearby star S0–2, when he was aware as it became brighter that it was the enigmatic supermassive monster , which is four million times the mass of our sun.

or lensing something beyond, or something else. Too early to tell. :dunno:

The first EHT image of Sag. A* shouldn't be too far from public release too... :party:

Here's a twitter link to a gif of the brightening by researcher Tuan Do.
