The black hole's X-ray emission documented by NASA was massive enough to note, offering hints at the great void's behavior at the center of the galaxy. The Milky Way revolves around a black hole, which at the center is 4.5 million times larger than the sun.

Is the massive black hole's x-ray emission a cause for alarm? Fortunately not; in spite of the event happening in a relatively quiet region of the galaxy, NASA has a couple of theories for the detected X-ray flare. The documented event happened September 2013, 400 times brighter than normally detected in the Sagittarius A* region (nasa.gov).

NASA's first theory is pretty mundane, and it involves an asteroid coasting too close to the black hole's proximity.

"If an asteroid was torn apart, it would go around the black hole for a couple of hours -- like water circling an open drain -- before falling in," MIT's Fred Baganoff said. He was referring to the superheated debris that emitted the X-rays while the asteroid was crossing the black hole's event horizon (cnet.com).

"That's just how long we saw the brightest X-ray flare lasts, so that is an intriguing clue for us to consider."

It's also possible the magnetic energy within the gas in Sagittarius A* got entangled, thus releasing the X-rays. The event is comparable to solar flares, according to NASA.

Gabriele Ponti of the Max Planck Institute for Astrophysics in Garching, Germany admits there's yet to be a concrete explanation for the black hole's X-ray emission, though: "The bottom line is the jury is still out on what's causing these giant flares from Sgr A*."

"Such rare and extreme events give us a unique chance to use a mere trickle of infalling matter to understand the physics of one of the most bizarre objects in our galaxy."

The event was discovered while scientists were using NASA's Chandra X-ray Observatory to observe how the region reacts to a neighboring gas cloud, known as G2.
