New Light Discovery Means Major Breakthrough In Understanding Black Holes!
2016 has progressed to an exciting start in the astronomy world! Scientists have observed the rare sight of visible light emanating from beside a black hole. Didn't know black holes existed? You're not alone. The National Aeronautics and Space Administration (NASA) explains in layman's terms what exactly a black hole is. According to NASA, a black hole is, "A place in space where gravity pulls so much that even light cannot get out." Scientists believe that these black holes have been around since the universe began.
This particular black hole is in the Cygnus constellation and is nearly 8,000 light years away. The Guardian News and Media clarifies that what creates this light that is apparently shining from a black hole is when material from surrounding space falls into one of the holes emitting x-rays that can appear as bursts of light. When matter and dying stars get sucked into the pits of gravity, the energy emitted is visible and while it may look like the light is coming out of the black hole, it is actually coming from beside it.
Typically, through the use of satellites and advanced telescopes, scientists are able to study these black holes. These tools help NASA and other agencies to track and measure these pockets of gravity. But, the Cygnus black hole is special. Researcher Mario Kimura spoke to space.com about this phenomenon saying, "We find activity in the vicinity of a black hole can be observed in optical light at low luminosity for the first time."
Measuring energy in the visible range is easily accomplished with the Konica Minolta CS-2000 Spectroradiometer. The CS-2000 measures the whole visible light range from 380nm to 780nm in 1nm increments. It can display all the radiometric and photometric data you need. It is also our most sensitive meter and can accurately measure color down to 0.003cd/m2.
