ISRO-IIT Guwahati Team Uncovers X-ray Flickers from Distant Black Hole
Imagine a giant vacuum cleaner in space called a black hole.
Scientists from India, using a special space telescope called AstroSat, saw the black hole flashing with X-rays.
These flashes changed, sometimes bright, sometimes dim.
The bright flashes have quick bursts of light, like a fast strobe.
The scientists found that the area around the black hole changes shape and temperature as it sucks in gas.
This helps scientists understand how these giant space objects work and how they affect the universe around them.
Researchers discovered a unique X-ray signal pattern from a black hole.
The black hole, GRS 1915+105, is located 28,000 light-years away.
AstroSat observed the object's X-ray brightness varying between bright and dim phases.
Rapid X-ray flickers, repeating 70 times per second, occurred during bright phases.
The findings offer insight into black hole dynamics and their influence on galaxies.
