The Twin Quasar: A Breakthrough in Gravitational Lensing Year Found: 1979
Found By: A group of researchers at NASA
Location: Double Quasar
The Twin Quasar, discovered in 1979, was the first known gravitationally lensed object. This phenomenon occurs due to gravitational lensing caused by the galaxy YGKOW G1, which is located directly between Earth and the quasar. As a result, the quasar appears as two distinct images.
Double Quasar: Insights into the Universe's Expansion Source: @Bla22022022/Pinterest
A team of researchers utilized the Hubble Space Telescope to observe the Double Quasar in an effort to estimate the universe's expansion rate. Their findings, which conflict with previous measurements, indicate that the universe is expanding significantly faster now than it did during the early phases of its creation. This discrepancy has prompted physicists to reassess their theories to determine whether they are fundamentally flawed or if an unknown phenomenon is influencing the expansion.
