Astronauts Use Gamma Rays To Measure Distance

1 min read


Astronomers have discovered a new way to measure the distance of the ancient universe. Because there are no landmarks or landmarks in space, it is difficult to perceive depth. They are using the ‘standard candles’ to know the brightness to measure distance in the space.

Absolute brightness refers to an object viewed from up close, and apparent brightness refers to an object viewed from a distance such as Earth.

The distance can be measured by calculating apparent brightness with absolute brightness. However, for objects more than 11 billion light-years away, measuring distances is challenging because there are no visible standard candles.
