ScienceDaily reported, a team of Japanese astronomers has discovered that our galaxy’items’ => 4,s central black hole let loose a powerful flare three centuries ago by using NASA, Japanese, and European X-ray satellites.
This finding helps resolve a long-standing mystery: why is the Milky Way’items’ => 4,s black hole so quiescent? Black Hole is an extremely dense celestial body that has been theorized to exist in the universe. The gravitational field of a black hole is so strong that, if the body is large enough, nothing, including electromagnetic radiation, can escape from its vicinity. The new study will appear in the Publications of the Astronomical Society of Japan, combines results from Japan’s Suzaku and ASCA X-ray satellites, NASA’items’ => 4,s Chandra X-ray Observatory, and the European Space Agency’items’ => 4,s XMM-Newton X-ray Observatory.
