Conclusion aconitum vilmorianum kom regulates the content of inorganic elements through its active assimilation . It has a good cooperated effect on the accumulation of ni and cr , fe and co , sn and co , and fe and sn .
What makes this one -- dubbed sn 1979c -- special is that it has been observed over the years with a series of orbiting x-ray telescopes , most lately the chandra x-ray observatory .
Those observations have revealed that sn 1979c has not dimmed in the 31 years since its birth , as would be expected if this was anything less than a genuine black hole .
If the object that was sn 1979c was a neutron star , the brightness of the x-rays it emits would tail off with time . But if it was a black hole , the x-rays would stay nearly as bright as the black hole gobbled new material .
