Earth-wide telescope
confirms black hole shadow is ‘real’
What's
in the news?
●
Scientists have unveiled new details of a colossal black hole 53 million light years
away first photographed by the earth-wide Event Horizon Telescope (EHT) in
2017.
●
The feat provided the first visual
evidence that black holes exist, confirming a fundamental prediction of
Einstein’s general relativity.
Key
takeaways:
●
The Event Horizon Telescope is a worldwide
network of radio telescopes that
work together.
Key
Findings by Event Horizon Telescope:
1.
Improved Resolution & Coverage:
●
Major Event Horizon Telescope findings
include improved resolution & Coverage as compared with previous one.
2.
Valuable Insights:
●
It provides valuable information into the
intricate dynamics near the Event horizon.
3.
Bright Ring & Dark Central Region:
●
They again find a bright ring of the same
size, with a dark central region and one side of the ring brighter than the
other.
4.
Asymmetric Ring Structure:
●
The finding confirmed the presence of an asymmetric
ring structure consistent with Gravitational lensing.
5.
Stable Ring Formation Process:
●
The findings have reaffirmed the Stable
ring formation process & other physical characteristics.
Event
Horizon Telescope:
●
It is a planet-scale array of eight
ground-based radio telescopes forged through international collaboration.
Objective:
●
It was designed to capture images of a black hole.
●
It offers scientists to research new frontiers of the Universe.
Technology
Deployed:
●
The Event Horizon Telescope observations
use a technique called very-long-baseline
interferometry (VLBI) to capture the images of black holes.
Partners:
●
Thirteen
partner institutions worked together to create the EHT.
●
Key funding was provided by the US
National Science Foundation (NSF), the EU's European Research Council (ERC),
and funding agencies in East Asia.
