Universe has show us much incredible things that just NASA can explain it with their highlight telescopes. Oneday NASA's NuSTAR (Nuclear Spectroscopic Telescope Array) mission detects that A Monster Black Hole and it sometimes lurks behind gas and dust, hiding from the gaze of most telescopes, and identified two gas-enshrouded supermassive black holes, located at the centers of nearby galaxies. Both of these black holes are the central engines of what astronomers call "active galactic nuclei," a class of extremely bright, hot, and emit radiation objects that includes quasars and blazars. Instead of seeing the bright central regions, our telescopes primarily see the reflected X-rays from the doughnut-shaped obscuring material.
Researchers analyzed NuSTAR data from this object and compared them with previous observations from NASA's Chandra X-Ray Observatory and the Japan-led Suzaku satellite. They found that something suprisingly which is more sensitive to higher energy X-rays than these observatories, confirm the nature of IC 3639 as an active galactic nucleus. Annuar's study discovered that this galaxy also has a thick column of gas hiding the central black hole, which could be part of a doughnut-shaped region. Researchers also found that NGC 1448 has a large population of young (just 5 million year old) stars, suggesting that the galaxy produces new stars at the same time that its black hole feeds on gas and dust. A black hole's location can be hard to pinpoint because the centers of galaxies are crowded with stars. Though it is hard, they are still detect around the black holes with large optical and radio telescopes so that astronomers can find their location and piece together the story of their growth.
