TEHRAN, May 07 -A space-based constellation of black- hole -hunting radio telescopes would be able to measure differences in the behavior of real black hole s and the characteristics predicted by Einstein's theory.
TEHRAN, Apr 10 - An international scientific team on Wednesday announced a milestone in astrophysics - the first-ever photo of a black hole - using a global network of telescopes to gain insight into celestial objects with gravitational fields so strong no matter or light can escape.
TEHRAN, July 15, YJC - The US Space Agency, NASA, says it has identified a huge hole on the surface of the Sun.The hole measures an estimated 75,000 miles wide. The telescopes at NASA's Solar Dynamics Observatory captured the large sunspot rotating into view from July 5 to 11. Sunspots are the cooler areas on the Sun’s surface, triggered by interactions with the star’s magnetic field. The hole is capable of producing huge solar flares, which send huge amounts of radiation out into the solar system. Scientists say it is still too early to predict how the sunspot will behave.
