Four high redshift quasars puzzle astronomers

A team of astronomers led by Joseph Hennawi of the Max Planck Institute for Astronomy, using the W.M.  Keck observatory in Hawaii, have discovered the first quadruple quasar: four quasars with approximately the same redshift of about z ~ 2 and located on the sky in close proximity.  The online article1 from Max Planck Institute is titled “Quasar quartet puzzles scientists” with the subtitle “Astronomers must rethink models about the development of large-scale cosmic structures.” This is a discovery of the first known group of four quasars with the same redshift found in the same location on the sky. A research paper has been accepted for publication in the journal Science and a preprint is now available.2

The quartet resides in one of the most massive structures ever discovered in the distant universe, and is surrounded by a giant nebula of cool dense gas. Either the discovery is a one-in-ten-million coincidence, or cosmologists need to rethink their models of quasar evolution and the formation of the most massive cosmic structures.1

The quasars are embedded in a giant nebula of cool dense gas visible in the image as a blue haze. The nebula has an extent of one million light-years across, and these objects are so distant that their light has taken nearly 10 billion years to reach telescopes on Earth. This false color image is based on observations with the 10-m-Keck-telescope on the summit of Mauna Kea in Hawaii. Credit: Arrigoni-Battaia & Hennawi / MPIA  (Ref. 1)

We look for the Saviour

If you survey the internet you’ll find almost an infinity of ideas and warnings of the End-times — the period around the return of Jesus Christ. People speak of the “blood moons” — lunar eclipses — the last of which just occurred in April 2015. I believe the excitement here is related to the biblical symbolism of the phrase “moon turned to blood” found in Joel 2:31, and repeated in Acts 2:20:

Joel 2:31 The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD come.

The “great and terrible day of the Lord” is the day of Christ’s return to rule as King. However, blood moons are astronomical phenomena, which occur like clockwork and can easily be predicted well in advance, because God has so ordered the heavens, like clockwork.  The “sun turned into darkness” symbolises a solar eclipse, which also can be predicted like clockwork. However God does use natural occurrences as signs and symbols. He used a rainbow to symbolise a covenant with Noah that He would never flood the whole earth again. The rainbow was not new to Noah, but God gave it a new meaning (Genesis 9:13-16). And in Acts 2:19 we read,
